Cinnamon Sugar Sweet Potato Fries with Vanilla Icing Dip.

Crispy baked sweet potato fries coated in cinnamon sugar and served with a sweet vanilla icing. I call these fries a potassium-rich dessert!

Cinnamon Sugar Sweet Potato Fries by @sallybakeblog

A couple weekends ago, Kevin and I met a few friends at a brewery in downtown Baltimore. We ordered some beer, shared a few appetizers, and while browsing the menu for dessert (always dessert) – our waitress suggested a plate of the sweet potato fries.

Um, what?

She said the fries are one of their most popular dessert items. These fries, coated twice with cinnamon sugar, are served with a lip-smackin’ sweet vanilla icing dip. There’s never a crumb left, she says. Well, twist my arm. Let’s order ’em.

Vegetables for DESSERT.

We ordered a plate and within 1 minute, the fries were gone. Cinnamon sugar coated our fingers and I considered licking the plate clean, only to be reminded we were in public.

Oh my gosh. I couldn’t get those overloaded sweet potato fries out of my head!! I made them the first chance I got. (The next day, clearly.)

Today I’m bringing you a baked version of their most popular dessert. But these aren’t just regular cinnamon sugar sweet potato fries! No no no. I brush them with a bit melted coconut oil, coat them twice with a heavy dose of sugar, and a generous spicy-sweet layer of cinnamon. The best darn way to eat your potassium and fiber if you ask me.

You’ll begin preparing the cinnamon sugar sweet potato fries exactly how you prepare my regular sweet potato fries. Wash and peel some sweet potatoes. The amount of potatoes depends on how many fries you want to make. For the two of us, I always use 2-3 large sweet potatoes. Rule of thumb: about 1 potato per hungry person.

Cut them into french fry shapes with a very sharp knife. I like to cut the fries to be a little thin. Not shoestring-style and not too thick. About 1/4 inch wide. Don’t stress about cutting them perfectly. They will all taste good… even the weird shaped ones.

Here’s a trick I’ve learned: toss your fries in a touch of cornstarch right after you slice them. Why? This creates a very thin layer of coating which helps the fries get crispy in the oven. You want cornstarch to go onto the fries before the oil and cinnamon sugar.

Here are the fries coated with cornstarch (left). And again after I’ve lightly coated them with coconut oil and sprinkled with cinnamon sugar (right). If you do not have coconut oil, you may use olive oil. Your fries will not taste like coconuts if you use coconut oil, don’t worry. You only need 2 Tablespoon per 3 potatoes for a light coating.

The coconut oil moistens the cinnamon-sugar. Sort of looks like brown sugar, right? When placing on the baking sheet, be sure not to crowd the sweet potatoes. Rather, make sure the fries have a bit of space in between one another. The less on the sheet, the better.

Why? Too many fries shoved together and they’ll just steam – not bake.

Cinnamon Sugar Sweet Potato Fries by @sallybakeblog

The fries bake in a hot oven at 400F degrees. Only about 18 minutes, flip, then 10-15 more minutes. As the fries bake, the cinnamon-sugar will melt into the coconut oil creating a little bubbly glaze. This is normal!

Here’s another trick that I’ve learned: once the fries are done, turn the oven off and crack open the door. Keep the baked sweet potato fries inside and let them sit inside for about 30+ minutes. Sitting in the oven as it cools down, rather than sitting at room temperature, will help your fries get crispier. When it comes to fries… the crispier, the better!

Obviously you may not have time for that last step, so it’s not mandatory. No matter what you do though, some fries will still be on the soft side. There is just no way around it! Sweet potatoes are packed with moisture.

Once the fries are done baking, you will coat them again in cinnamon sugar. These baked sweet potato fries are absolutely not health food with all that sugar. No wonder they are considered dessert!

Let’s not forget about the glaze. A simple combination of confectioners’ sugar, cream, and vanilla. Three of my favorite ingredients in one. Double dipping is absolutely encouraged.

Or just drizzle the glaze all over. ↑ That was Kevin’s idea. I knew I was marrying this man for a reason. My god, I could eat this entire plate right now. Enjoy!

Cinnamon Sugar Sweet Potato Fries with Vanilla Icing Dip

Crispy baked sweet potato fries coated in cinnamon sugar and served with a sweet vanilla icing. I call these fries a potassium-rich dessert!

Ingredients:

  • 3 large sweet potatoes1
  • 1 Tablespoon cornstarch
  • 2 Tablespoons melted coconut oil (or olive oil)
  • 2/3 cup granulated sugar
  • 1 teaspoon ground cinnamon

Vanilla Glaze Dip

  • 1 cup confectioners' sugar
  • 2-3 Tablespoons heavy cream (or milk for a less creamy texture)
  • 1/4 teaspoon vanilla extract

Directions:

  1. Preheat oven to 400°F (204°C). Line a large baking sheet with parchment paper or a silicone baking mat. 2 large sliced potatoes are usually too crowded on 1 sheet, but it depends on their size. You may need an additional sheet. Set aside.
  2. Wash and peel the potatoes. Cut off the ends. With a very sharp knife, cut the potatoes into thin slices about 1/4 inch wide. Place in a large bowl or ziplock bag and toss with cornstarch. You want a nice thin coating. Pour the potatoes into a strainer to get rid of any extra cornstarch. Discard the extra cornstarch out of the mixing bowl too. Place potatoes back into the bowl and add the melted coconut oil. Toss to coat. Mix together 1/3 granulated sugar and 1/2 teaspoon cinnamon. Pour cinnamon sugar over sweet potatoes and toss to coat.
  3. Line the coated sweet potatoes onto the baking sheet. Try not to crowd them or else they won't bake, they'll just steam. Bake for 15-18 minutes. Remove from the oven and flip. Place back into the oven for 10-15 more minutes. Make sure to rotate the pan to avoid uneven browning. Don’t fret if the edges are a little brown, they will taste more caramelized than burnt. **It's expected for the oil and cinnamon/sugar to create a glaze on the baking sheet and on top of the fries.
  4. Turn the oven off and keep the fries inside as the oven cools down for about 30 minutes. This step will help the fries get crispier. You may not have time to keep them in the oven for an additional 30 minutes as it cools, so it’s not mandatory. No matter what you do though, some fries will still be on the soft side. Sweet potatoes are packed with moisture.
  5. Remove fries from the oven and place in a large bowl. Combine the remaining 1/3 cup granulated sugar and 1/2 teaspoon cinnamon and pour over fries. Toss gently to coat.
  6. Serve with vanilla glaze dip. For the dip, simply whisk all of the ingredients together. I usually start with 2 Tablespoons of the cream and add 1 more if it seems too thick. Enjoy immediately.
  7. Make ahead tip: Freeze these fries! Baked sweet potato fries freeze well for up to 3 months. Bake in a 375°F (190°C) oven for 15 minutes or until defrosted and crisp.

Recipe Notes:

  1. I estimate about 1 large sweet potato per person. The amounts above are for about 2-3 people. For a large batch, double the recipe.

    Ummmm I love you. Can I just say that? HEALTHY dessert made with the greatest vegetable known to mankind? Oh gosh I have all the ingredients to make this too… brb 🙂

    • Kristen on June 5, 2014 at 3:41 am

      Its not healthy! Lotsa sugar in the glaze. But don’t care about that! Its too delcious looking!

    • Sally on June 5, 2014 at 5:42 am

      Yeah! I wouldn’t call them healthy but hey, still loaded with vitamins for sure 😉

      • Hayley on June 5, 2014 at 10:09 am

        Oh…. I live in this special world where sugar is good for you. 😉



      • Sally on June 5, 2014 at 11:19 am

        Can I move there?



      • Hayley on June 5, 2014 at 11:46 am

        Sure! All sugar-lovers are welcome 🙂



  2. Amy @ Thoroughly Nourished Life on June 5, 2014 at 2:20 am

    These look absolutely amazing! Perfect warm wintertime dessert for us down here in Aus too 🙂
    Something in me is imagining them with a savoury topping as well…maybe just some salty cottage cheese. Yum 🙂
    Thanks Sally for a little healthy somethin’ somethin’ to add to my dessert menu!

  3. Amy @ Amy's Healthy Baking on June 5, 2014 at 2:38 am

    These are so creative — I love it!! Just one more reason I’m a dessert-aholic: I can say it’s healthy because I’m getting an entire serving of veggies. And your version is even better because they’re baked, not fried! 😉 I always wonder how chefs come up with these brilliant ideas. Was it pure accident that they spilled cinnamon sugar on one customer’s savory sweet potato fries? Or did the vanilla icing for cupcakes somehow drip onto someone’s burger and fries? Or was it completely planned from the start? Whatever it is, I wish I had more of those genius moments myself!

    • Sally on June 5, 2014 at 5:41 am

      Spilling vanilla icing on fries and a burger just made me laugh for some reason. Who knows, maybe that’s true!

  4. Liz S. on June 5, 2014 at 2:43 am

    WOW! What a delectable way to enjoy sweet potato fries.

  5. Averie @ Averie Cooks on June 5, 2014 at 3:20 am

    These have got to be like eating straight up dessert and I love that! Between the coconut oil, and how I love it with sweet potatoes, the cinn/sugar, the icing, omg so good! I did a sweet-and-savory sweet potato recipe that I put in my first cookbook. They were PB & J fries but the jelly was like a savory jelly with savory peanut sauce. I remember that shoot like it was yesterday but I digress 🙂 These are great, Sally! Pinned!

    • Sally on June 5, 2014 at 5:39 am

      It WAS our dessert at the restaurant. These are so, so good. You’d love them!

  6. Virginia G on June 5, 2014 at 3:53 am

    This is gorgeous and looks delicious! There’s just no way I would ever be that patient! I’m thinking more like cinnamon sugar mashed sweet potatoes. Like a hot version of ice cream or something. I barely have the patience to peel my sweet potatoes, much less chop them into tiny strips and bake them and let them rest. But if someone wanted to do it for me…

    • Sally on June 5, 2014 at 5:38 am

      I absolutely am making cinnamon sugar sweet potatoes soon now.

  7. Taylor @ Food Faith Fitness on June 5, 2014 at 6:04 am

    WHOA BABY. I didn’t think sweet potato fries got much better – but, cinnamon sugar and vanilla icing dip! I MUST TRY THIS.
    I like Kevin’s drizzling the icing all over idea. Sometimes these men come up with some good ones! Pinned!

  8. Caley on June 5, 2014 at 6:13 am

    I’m glad you have a wonderful souvenir from Colorado 🙂 These look fantastic…so incredibly delicious. They are like much healthier churros or something 🙂 I’m sure icing on top or cream-cheese frosting to dip would be great with them…or caramel! Or maple syrup! 😀

    • Sally on June 5, 2014 at 8:25 am

      Caramel!!! This is why I love you Caley.

  9. Chloe @ foodlikecake on June 5, 2014 at 6:41 am

    Yum! These look amazing!

  10. Bearecetasymas on June 5, 2014 at 7:33 am

    They look great and so creative, like them so much!!!

  11. Gayle @ Pumpkin 'N Spice on June 5, 2014 at 8:07 am

    Aren’t these fries the best?! I made cinnamon sweet potato fries about a month ago, and they were hands down my favorite fry ever! I love the added touch of the vanilla icing!

    • Sally on June 5, 2014 at 8:24 am

      Yes, absolutely the BEST Gayle! Happy you love ’em too.

  12. youmna on June 5, 2014 at 8:43 am

    they look absolutely amazing sally!

  13. Mary Frances on June 5, 2014 at 8:52 am

    Anything baked means its breakfast worthy! My family has always eaten sweet potatoes for dessert, but not in fry form and definitely not covered in addictive finger licking cinnamon and sugar goodness. I think this might be the best thing since sliced bread, Sally!

    • Sally on June 5, 2014 at 11:21 am

      Mary Frances, I knew I loved ya for a reason. Fries for breakfast is how everyday should start… right?

  14. Linda @ Veganosity on June 5, 2014 at 9:03 am

    I LOVE, LOVE, LOVE sweet potato fries, but for dessert? Who knew?!? These are on my to make list. I might skip the glaze though, I’m not a fan of sticky, or too sweet, so the cinnamon sugar and the sugar from the potatoes should be just right.

    Thanks for sharing this, and the tip about letting them cool in the oven. Brilliant!

  15. Lina on June 5, 2014 at 9:28 am

    Wow, these look absolutely incredible. As soon as I saw the title, I said, “Sweet potato fries for DESSERT?!?!” You had me hooked, and as I read the recipe, I started salivating. I need to try these ASAP!!!

    • Sally on June 5, 2014 at 11:20 am

      Thanks Lina – let me know if/when you try them.

  16. Lindsay @ Life, Love and Sugar on June 5, 2014 at 9:51 am

    Ok, these are absolutely criminal! I’m dying! As if the cinnamon sugar coating wasn’t enough, you had to add the vanilla icing! It’s a like a dream come true!

  17. Violet on June 5, 2014 at 10:06 am

    I can’t wait to try this recipe…sweet potato fries are one of my most favorite things ever, and these definitely kick it up a notch!!!! Yummers…

  18. Beth @ bethcakes on June 5, 2014 at 10:13 am

    I saw that first photo and almost fell out of my chair. Lol! These look sososo good and I’m not even the biggest sweet potato fan. I love that you brushed them with coconut oil first and then added the cinnamon sugar. Yes, I’ll have some potassium and fiber with my vanilla icing dip, thanks. 🙂

    • Sally on June 5, 2014 at 11:19 am

      Hahaha Beth I love a recipe that has both vitamins and fiber, as well as vanilla icing.

  19. Lisa @ Simple Pairings on June 5, 2014 at 10:34 am

    Salty + sweet heaven! I love sweet potatoes anyway, but what you’ve done to them is incredible! I love how something so simple can be so enticing.

  20. Karly on June 5, 2014 at 10:52 am

    Fries for dessert. I can get down with that.

  21. Kristy @ Sweet Treats & More on June 5, 2014 at 11:08 am

    Can I eat these for breakfast? Because I’m totally craving some now:) Anything is acceptable when pregnant right?!?

    These look amazing Sally!!

    • Sally on June 5, 2014 at 11:15 am

      YES. I approve of that breakfast. 🙂

  22. Faith @ Pixie Dust Kitchen on June 5, 2014 at 11:10 am

    I love that these are sweet and not savory! I’m not a huge fan of sweet potatoes but coated with that dreamy vanilla glaze? YES PLEASE.

  23. Jordan @ The Blonde Vegan on June 5, 2014 at 11:22 am

    Hooooly crap these look amazing. I will have to figure out a vegan-friendly version, or else I will just be drooling over these food photos all day!! (That wouldn’t be so bad either.)

    • Sally on June 5, 2014 at 11:33 am

      Besides the cream in the icing dip, this recipe is vegan. Maybe a soy milk or nondairy creamer would be best. Enjoy!

  24. Lauren on June 5, 2014 at 11:41 am

    This isn’t a health food?! I have been reading everywhere sweet potatoes are totally better for you than white potatoes. And I mean, they’re just considered one of the top health foods… So this HAS to be healthy 😉

    I love my fries to be crispy, so I love the idea of keeping them in the warm oven! Totally brilliant but almost impossible to wait so long! Ha!

    • Sally on June 5, 2014 at 3:47 pm

      I love your logic, Lauren 😉

  25. danielle on June 5, 2014 at 11:55 am

    YUM!! Pinned – I need these 🙂

  26. Ala on June 5, 2014 at 12:45 pm

    I know exactly what I’m making for tomorrow’s friend dinner–I made savory sweet potato fries last night, but now I”m craving these like crazy (and let’s face it, I could use the help in finishing these off–last night I ate two WHOLE sweet potatoes in one sitting! Yeeps!). So glad you could share these wonderful spin-offs!

    • Sally on June 5, 2014 at 3:44 pm

      Ala, I could easily eat 2 large sweet potatoes worth of fries without batting an eye. It sounds like you love the fries as much as I do!

  27. Jess @ On Sugar Mountain on June 5, 2014 at 1:40 pm

    Oh man I never think to do sweet potato fries like this (I always go for a savory touch) but these look amazing Sally! That icing!

  28. Madeleine on June 5, 2014 at 1:50 pm

    Wow, what a great recipe! I could totally see myself using these as a base for a “dessert nacho” type of dish. Maybe load them up with chopped nuts and chocolate/caramel as well? Not exactly health food, but I’m all about finding a balance when it comes to food!

    • Sally on June 5, 2014 at 3:44 pm

      Love those ideas – especially with a drizzle of caramel and chopped nuts!

  29. Polly @ Tasty Food Project on June 5, 2014 at 2:28 pm

    I love sweet potato fries and that vanilla icing dip looks amazing!!

  30. PJ on June 5, 2014 at 2:39 pm

    These look amazing! Another great dessert idea 🙂 thanks Sally!
