I leave for St. Lucia on Thursday! My friend from college, Kristin, is getting married and we are headed down for a long weekend for the wedding! I’ve never been to the Caribbean before. Kevin’s not able to go because he has a wedding to go up here in Maryland. It’s wedding season! Anyway, I’m excited to spend some much needed time with my girlfriends.

There will be sundresses, laughs, frozen drinks, and many trips down memory lane.

Today’s recipe has nothing to do with my upcoming tropical vacation (other than these cookies are NOT bikini-friendly), but it is certainly a recipe I couldn’t wait to share with you. I had plenty of leftover Reese’s Pieces from my Lightened-Up Peanut Butter Ice Cream Pie last week, so I made us a new batch of cookies.

Today’s cookies win first prize in the soft cookie category. Can’t you just see how tender they are? They will melt in your mouth. Try crumbling them on top of vanilla frozen yogurt! The recipe I used to make them is the same base recipe as my ever-so-popular Chewy Chocolate Chunk Cookies. Talk about going viral – in the first 10 days these cookies were posted, they were pinned on Pinterest over 120,000 times! I am floored. But, simultaneously, not surprised at all.

It’s a base recipe I tested over and over and over again. And then, I tested it some more. I was swimming in cookies during April. The trick to getting them so soft? So chewy? So thick? So… perfect? Extra brown sugar, less white sugar, extra baking soda, add cornstarch, add an extra egg yolk, extra underbake them, melt the butter, chill the dough, and use just enough flour.

Wow – who knew there was so much going into baking a cookie? Well, there is. Baking cookies is like a science. And while science was never my forte in school, I’m a huge cookie science nerd. I feel like a mad scientist in the kitchen sometimes. Ahh!

Here is the cookie dough, just so you can see how soft it is. Note it is pictured with chocolate chips and not today’s add-ins. 🙂 But you get the idea!

Chocolate Chip Cookie Dough

The cookie dough is straightfoward. There’s nothing strange or unheard of going into the dough. The preparation is simple. There is no mixer required – just two bowls and some stirring.  And as long as you follow the instructions and chill the dough for the recommended time (the most important step!), your cookies will come out wonderfully.

Butterscotch and Reese’s Pieces are my add-ins of choice. What a combination! You would think I work for Reese’s Pieces for as many times that I use them in recipes, but I assure you – I don’t. I just love them that much.  Did you know that inside a box or bag of Reese’s Pieces you will find 50% orange, 25% yellow, and 25% brown?  I always wondered why there were so many orange! It’s my favorite color.

Moving along.

If you’ve never tried butterscotch and peanut buttery things together, I highly recommend that you do.  Butterscotch and its rich caramel/brown sugar notes pairs wonderfully with Reese’s anything.  The butterscotch chips fooled many taste-testers for peanut butter chips upon first site. It was a pleasant surprise after the first bite, they said!

This is an easy cookie recipe you need to add to your rotation. Simple clean-up and simple process leading to out of this world results. These soft, buttery, chunky cookies are a new favorite!

Soft-Baked Reese's Pieces Butterscotch Cookies

Soft-baked and ultra chewy cookies loaded with butterscotch and Reese's Pieces candies. Use any of your favorite add-ins instead!

Yield: 16 large cookies

Ingredients:

  • 2 and 1/4 cup all-purpose flour (spoon & leveled)
  • 1 teaspoon baking soda
  • 1 and 1/2 teaspoons cornstarch
  • 1/2 teaspoon salt
  • 3/4 cup (1.5 sticks) unsalted butter, melted and slightly cooled1
  • 3/4 cup light brown sugar, loosely packed
  • 1/2 cup granulated sugar
  • 1 large egg + 1 egg yolk2
  • 2 teaspoons vanilla extract
  • 3/4 cup butterscotch chips
  • 1/2 cup Reese's Pieces

Directions:

  1. Whisk the flour, baking soda, cornstarch, and salt together in a large bowl. Set aside.
  2. In a medium bowl, whisk the melted butter, brown sugar, and granulated sugar together until no brown sugar lumps remain. Whisk in the egg, then the egg yolk. Finally, whisk in the vanilla extract. The mixture will be thick. Pour the wet ingredients into the dry ingredients and mix together until combined. The dough will be very soft, yet thick. Fold in the chocolate chips. The chips may not stick to the dough because of the melted butter, but do your best to combine them. Cover the dough and chill in the refrigerator for 3 hours or up to 2-3 days. Chilling is mandatory. I highly recommend chilling the cookie dough overnight for less spreading.
  3. Take the dough out of the refrigerator and allow to slightly soften at room temperature for 10 minutes.
  4. Preheat oven to 325°F (163°C). Line two large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.
  5. Roll the dough into balls, about 3 Tablespoons of dough each. The dough will be crumbly, but the warmth of your hands will allow the balls to stay intact. Roll the cookie dough balls to be taller rather than wide, to ensure the cookies will bake up to be thick. Put 8 balls of dough onto each cookie sheet. Press a few more butterscotch/Reese's on top of the dough balls for looks, if desired. Bake the cookies for 11-12 minutes. The cookies will look very soft and underbaked. They will continue to bake on the cookie sheet.
  6. Allow to cool on the cookie sheet for 10 minutes before moving to a wire rack to cool completely.

Make ahead tip: Cookies stay fresh covered at room temperature for up to 1 week. You can make the cookie dough and chill it in the refrigerator for up to 2-3 days. Allow to come to room temperature then continue with step 4. Baked cookies freeze well for up to 3 months. Unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Click here for my tips and tricks on freezing cookie dough.

Recipe Notes:

  1. Salted butter can be used instead. Reduce salt in the cookie dough to 1/4 teaspoon.
  2. Room temperature egg + egg yolk are preferred. Typically, if a recipe calls for room temperature or melted butter, it's a good idea to use room temperature eggs as well. To bring eggs to room temperature quickly, simply place the whole eggs into a glass of warm water for 5 minutes. What to do with the extra egg white? Make these or these.

  1. I am sitting here letting them chill now before baking and OOPS I did an egg and extra egg white, not a yolk haha. Will let you know how they turn out but I am sure they’ll still be amazingly delicious!

  2. SALLY. SWEET SALLY.  How have these been on your site for two years and I am just making them now??  Anyway, I usually make your peanut butter lovers cookies (and they are great!) but I was looking for something different.  I saw this recipe and (thinking it was a peanut butter cookie recipe because I didn’t read carefully (distracted by the oh so awesome photos)) I just had to try it.  I put Reese’s chips and chocolate chips in the batter.  OH. MY. GOD. cookie perfection.  Every single one came out beautifully.  They are a little crisp on the outside and soft on the inside.  I have made a lot of cookies Sally, a lot of cookies.  These are the best cookies I have ever made.  That is a very bold statement!!  Everyone is raving about them.  You say they stay fresh for a week…I guarantee they will not last that long!!  Can’t wait to try them with the other mix-ins you suggest.  Thanks!! 🙂

  3. Can I make them using margarine? 

  4. Question: i want to make these cookies (soft baked reeces…) but bite sized instead of full sized for goody bags. How would i adjust baking time or do I need to?

  5. Yay, I made this dough yesterday. Can’t wait to get up in a few and get to baking! I even made 2 batches lol. 

  6. Never thought I’d find a cookie that I like…no…love, more than white chocolate macadamia…well this recipe knocks it out of the ballpark!  These are beyond delicious!!!
