Chocolate Peanut Butter Protein Smoothie

There’s a whopping 28 grams of protein in this chocolate peanut butter cup smoothie– no protein powders either!

I’m publishing this post from Kevin’s parents’ home. Our apartment’s pipes bursted today and our home flooded. Water gushing from the ceilings and up through the floor. I pre-wrote this recipe about 1 hour before it all happened. We had to pack up everything and move to a new apartment. Our new place does not have internet or running water yet. Some things were destroyed but thankfully, nothing of large value was ruined. Everything will be just fine. Worse things have happened to better people, at least that’s what I always think in a calamitous situation.

Ok, let’s move onto more positive things!

Alternate names for this recipe: Skinny Peanut Butter Cup Dairy Queen Blizzard, Healthy Peanut Butter Cup Milkshake, Heaven On Earth.

If you’re anything like me, when life throw’s you a curveball – the only thing to keep you afloat is a spoonful of peanut butter studded with chocolate chips. And/or a sale on boots at Nordstrom. Peanut butter and chocolate is a winning combination no matter how it’s paired. I mean a batch of dreamy Reese’s Stuffed Peanut Butter Cookies could probably change lives. Don’t believe me? Try them.

I’m a self proclaimed peanut butter chocolate addict. Don’t send help.

Despite the 3 degree temperature outside (with -15 degree windchill – it’s even colder in the midwest!) I’ve been drinking my weight in cold, creamy smoothies. Earlier this week I made a concoction with blueberries, frozen bananas, strawberries, almond butter, spinach, and everything but the kitchen sink. Purely delightful.

But today? I wanted life’s most comforting flavor combination after my workout this morning. And it just so happens this drink is full of protein. Well, it’s actually pure protein. A whopping 28 grams of protein in 1 huge smoothie.

I am not a fan of protein powder at all because it tastes like chalk dust to me. Maybe I haven’t found a good brand yet? I’ve been searching for years. And to be honest, it’s quite pricey! I’d rather take in protein from pure sources.

Here’s the protein breakdown of my new favorite smoothie:

  • 6 oz greek yogurt → 18 grams
  • 3/4 cup skim milk → 6 grams 
  • 1 Tablespoon Skippy natural peanut butter → 4 grams

28 grams. Unreal, right? Because of all the protein, this smoothie will not have you starving 5 minutes later. It held me over for hours. And the best part? It tastes so damn good. There, I said it. Damn good, you guys.

It’s like a drinkable, protein-packed peanut butter cup.

Like most of my healthy smoothie and milkshake recipes, you’ll start with frozen banana chunks. What’s so great about frozen banana chunks? It makes the healthiest, purist, creamiest base for a super thick smoothie. In fact just the other day I had a giant bowl of blended frozen “banana whip” (just 2 frozen bananas cut into chunks then blended with a touch of milk) and sprinkled mini chocolate chips on top. Tastes like ice cream, not kidding. Try it!

So today’s smoothie starts with 1 ripe banana, cut into chunks and frozen. Don’t worry, you won’t be able to taste the banana with the chocolate and peanut butter. Blend the banana up with some Greek yogurt, milk, cocoa powder, honey, and peanut butter. The 1 teaspoon chocolate syrup swirl you see is just because I was feeling fancy. 🙂

And for the peanut butter? Use homemade honey-roasted, natural style, crunchy, creamy, flavored, any of the 20 jars of peanut butter I know you have in your pantry right now. Or is that just me? Moving on…

Blend it all up into creamy oblivion. And by creamy, I mean out of this world creamy. So creamy and thick, this smoothie should really be called a milkshake. If you want the smoothie a little thinner, add a little more milk. If you want it more chocolate-y, add more cocoa powder. There’s a lot of ways to play around with this recipe.

And hey, guess what? Feel free to go all green on me. Add a handful of greens like spinach or kale. You absolutely won’t be able to taste them underneath all the peanut butter and chocolate tastes.

So go ahead, indulge in life’s best flavors swirled together. Fuel your muscles, please your tastebuds, brighten your day (because you never know when your life will be turned upside down), and jump for joy. Cheers!

Chocolate Peanut Butter Protein Smoothie

  • Author: Sally
  • Prep Time: 5 minutes
  • Cook Time: 0 minutes
  • Total Time: 5 minutes
  • Yield: 1 large smoothie
  • Category: Drinks
  • Cuisine: American


There’s a whopping 28 grams of protein in this chocolate peanut butter cup smoothie– no protein powders either!


  • 1 large banana, peeled, sliced, and frozen
  • 3 Tablespoons unsweetened cocoa powder
  • 6 oz Chobani 0% Greek yogurt (or 2%, flavored or unflavored)
  • 3/4 cup skim milk (or your favorite kind of nondairy or dairy milk)
  • 1 Tablespoon honey, maple syrup, or agave
  • 1 Tablespoon peanut butter (any kind you like)


  1. Make sure you have a strong, powerful blender that will blend up the frozen banana. I like this Ninja or this Vitamix.
  2. Put all of the ingredients into the blender, in the order listed, and blend on high until thick and smooth. I would start with only 2 Tablespoons of cocoa powder, blend, and then add 1 more for a stronger chocolate taste. You may need to stop and stir/scrape down the sides of the blender a few times.
  3. Drizzle glass with 1 teaspoon of chocolate syrup (optional) and enjoy!


  1. So many ways to play around with this simple smoothie! If you prefer a less sweet smoothie, you can leave out the honey. Add more peanut butter for a stronger peanut butter taste. Add more milk to make the smoothie thinner, if desired. Add 1 cup of your favorite greens for added nutrition.

    Can’t wait to try this smoothie but just want to wish you the best with the crisis you’re facing in your home with busted pipes. I have a similar attitude of “it could always be worse”. Best regards.

  2. I calculated the calories in the smoothie, its approximately 375 if you use 1 tsp maple syrup and 2 T cacao powder. However there is only 20 g protein, where did you get 28 g from? I haven’t made it yet, so I can’t comment on the taste but im looking forward to trying it in the morning. Thanks for creating this recipe without protein powder. I’m thinking of adding hemp hearts to add some more protein and maybe some pumpkin seeds too, we’ll see. 

    1. 4g in the PB, 18g in Greek yogurt, 6g in skim milk. Enjoy!

  3. Hi, Sally. I’m eager to try this smoothie but have a couple questions:

    1 – How prominent is the banana flavour in this? I like bananas, but would prefer to not have a smoothie completely taste like bananas. 
    2 – If this is one “very large” smoothie, would it comfortably serve 2 people for a light breakfast?
    3 – Which do you like better (sorry if it’s a hard question!) your peanut butter chocolate smoothie or your peanut butter & jelly one? 

    Thanks so much 🙂

    1. Hey Hayley! The banana flavor is not prominent at all. The chocolate and peanut butter mask pretty much all of it. It can easily serve 2 for a light breakfast. I’m a die-hard fruit lover, so the peanut butter and jelly version easily wins 🙂

  4. Pam Holland says:

    How can I make smoothie without bananas? I’m allergic to raw banana but can eat like a banana cake with it cooked.

  5. What plain greek yogurt are you using that has 18 grams of protein in it, because all the kinds that I have do not have that much protein in them.

  6. I made this but used Sweet Leaf stevia instead. Fantastic and it doesn’t send my blood sugar into the atmosphere. I also put 8-10 ice cubes in it. Turned out to be a choco/banana/pb milk shake. Yum!

  7. Yummy!! This is a lot like the cheerful chocolate smoothie in your cookbook! I love it. thank for make incredible chocolate smoothie….

  8. Jacki Lemmerman says:

    I made this exactly like the directions said and it is very thin and watery (not thick and creamy at all!) what did I do wrong?

  9. Ellie Macdonald says:

    This chocolate smoothie is really great! This looks delicious and I’m sure I’ll like it! Thanks for share..

  10. Hi, I just made it and it was lovely! I didn’t have any banana, so I used avocado instead. It seemed like a really big smoothie, so I only made half, and it was enough for one. Thank you for the amazing recipe!

  11. Do you think it would last in the fridge overnight?

    1. It should, yes!

  12. Jane Rothwell says:

    How many calories is in this… I counted over 5oo…. milk is 90, cocoa 25, peanut butter 100 ( I jused a little more) honey 65, yogurt 150 and banana 121.

  13. How do you think pb2 would work with this? I know it wouldn’t be quiet as creamy without the added fat…

    1. Hi Heather, I haven’t tried it with PB2 but the frozen banana and yogurt should still keep it pretty creamy. Let me know if you try it!

  14. American Pit Bull Terrier says:

    This website really has all the information and facts I
    wanted about this subject and didn’t know who to ask.

  15. Do you have to use frozen bananas or can they be fresh?

  16. I just made this smoothie and it is delicious! I used your exact recipe but added 1 scoop of vanilla protein powder.

  17. My daughter is trying a vegetarian diet, and I wanted to make her a “Dessert” smoothie to get some protein in – holy smokes, this is amazing. I doubled it bc life is hard. Subbed frozen vanilla yogurt for the Greek yogurt and accordingly omitted the honey, used Ovaltine in place of cocoa and added the wee tiniest smidge of peanut butter powder along with the real PB. I’ll use the cocoa next time bc I sacrificed some flavor by using the Ovaltine. And there will definitely be a next time!
