I never believed I could add protein powder to a peanut butter cup and still *actually* enjoy the flavor. That’s why I’m so excited about these protein peanut butter cups. They have 9 grams of protein per cup, and don’t taste like protein powder at all. (Seriously!)

If you love candy as much as I do, you’ll also love my healthy Snickers, homemade crunch bars, healthy Almond Joy, and gluten-free Twix bars.

Why You’ll Love These Protein Peanut Butter Cups

They actually taste good. Have you ever tried a recipe with protein powder and thought it was “fine” but not “great?” That’s not the case here. These actually don’t taste like protein powder AT ALL. Like, you’d never guess if you didn’t just make them yourself.

They are easy. The peanut butter filling has 4 simple ingredients that you can stir together fast. The hardest part is melting the chocolate chips!

They have extra protein without being chalky. Texture matters with peanut butter cups, so I tested a few different types of unsweetened protein powder (no stevia!) to see what worked best. Just read the comments below if you don’t believe me.

Ingredients You’ll Need

peanut butter, collagen, maple syrup, and chocolate chips labeled.
  • Peanut Butter. Use all-natural creamy peanut butter for the best peanut butter flavor. This means you’ll have to stir well when you first open the jar. If you prefer a crunchy texture, crunchy peanut butter works, too. Use sunflower seed butter for a nut-free treat, or use cashew butter or almond butter for a peanut-free option.
  • Collagen Peptides. I use unsweetened collagen peptides to thicken the peanut butter center and add protein to each cup. If you want to experiment with another protein powder, keep in mind that flavor and texture can vary dramatically by powder. When I tried using a plant-based protein powder, just 1 tablespoon was too much flavor-wise.
  • Maple Syrup. This natural sweetener adds the perfect amount of sweetness to the peanut butter center.
  • Salt. When making a sweet treat, don’t omit the salt. It helps make the flavor irresistible.
  • Chocolate Chips. The coating is easiest to make with melted chocolate chips and a teaspoon of coconut oil to thin the texture. Use semi-sweet chocolate for a sweeter flavor, or use darker chocolate if you prefer less sugar.

How to Make Protein Peanut Butter Cups

Step 1:

Line a muffin tin with 9 paper or silicone muffin liners. Combine the chocolate chips and coconut oil in a heat-safe bowl that fits snugly over a small saucepan. Add an inch of water to the saucepan and bring it to a boil on the stovetop. 

Once the water is boiling, place the heat-safe bowl filled with chocolate chips over the top of the pan. Stir until the steam gently melts the chocolate; the coconut oil will dissolve, thinning the texture and making it pourable. 

Note: Alternatively, you can microwave the chocolate in 30-second intervals. The chocolate won’t melt quite as evenly with this method, and it won’t stay melted as long as it does when you keep the bowl over the pan of hot water. The double-boiler method mentioned above is preferred.

Step 2:

Add 2 teaspoons of melted chocolate to each muffin liner. Then, tilt the pan to swirl the chocolate around the lower edges of each cup. Place the pan in the freezer for 10 minutes, or until the chocolate sets. 

Meanwhile, add the all-natural peanut butter, collagen, maple syrup, and salt to a medium bowl. Stir until the mixture resembles moist cookie dough. (You should be able to roll it into a ball, almost like Play-Doh.)

Step 3:

Remove the pan from the freezer and add a tablespoon of the peanut butter mixture to the center of each cup. Flatten the peanut butter layer slightly, leaving some room around the edges of each muffin cup so the chocolate can coat them. 

Once you’ve used all of the peanut butter mixture, add 2 more teaspoons of melted chocolate to the top of each cup. It should totally coat the top and edges of each muffin cup. 

Sprinkle flaky sea salt on top, if you like.

Step 4:

Return the muffin pan to the freezer until the chocolate is firm. Then these are ready to enjoy! Because coconut oil has been added to the chocolate, these treats could melt at room temperature.

Store in an airtight container in the refrigerator for up to a month, and enjoy chilled for the best texture. (They will not last a month before you eat them all… we’re lucky if they last 3 days!)

Lower-Calorie Option

You can use less chocolate and therefore lower the calories by adding it only to the top of each peanut butter cup. (Skipping the bottom and sides.) See the photo below to picture what that looks like!

Protein Peanut Butter Cup Recipe FAQs

Can I make peanut butter cups in a mini muffin tin?

Of course! Check out my mini peanut butter cups recipe for photos; I use a teaspoon of chocolate on the top and bottom, with less peanut butter mixture per cup. You should get at least twice as many peanut butter cups this way. 

Can I skip the chocolate chips?

You can make your own chocolate shell using my magic shell recipe, if you prefer, but the peanut butter cups may melt too quickly in that case. Coconut oil will melt in your hands, so using dark or semi-sweet chocolate chips makes this recipe more shelf-stable.

Protein Peanut Butter Cups (That Taste Good!)

5 from 7 votes
These Protein Peanut Butter Cups taste better than the Reese's version, so you'd never guess they have extra protein hidden in each bite. (Truly, you can't taste the protein powder at all.) They have 9 grams of protein per cup, so they will leave you feeling satisfied longer than a traditional candy bar, too.

Instructions

  • Line a standard muffin pan with 9 parchment paper liners. To melt the chocolate, add an inch of water to a small saucepan and bring it to a boil on the stove top. In a heat-safe bowl that will fit snugly over the top of the saucepan, add the chocolate chips and coconut oil. The steam from underneath the bowl will gently melt the chocolate; stir occasionally until smooth. The coconut oil will thin the consistency so it's easier to pour.
  • Add 2 teaspoons of melted chocolate to each muffin liner. Then gently tilt the pan on all sides, so the chocolate starts to coat the lower edges of each muffin cup. (This will help create nice edges, but is optional.) Place the pan on a flat shelf in your freezer while you work on the next step.
  • In a medium bowl, combine the peanut butter, collagen, maple syrup, and salt. Stir well, until the dough looks uniform. Then, remove the pan from the freezer and scoop about a tablespoon of peanut butter into the center of each muffin cup.
  • Gently flatten the top of each peanut butter mound with your fingers, so it will be easier to cover in chocolate. It's ideal if the peanut butter doesn't go all the way to the edges of the muffin cups, so chocolate can fill-in the sides. Pour 2 teaspoons of the melted chocolate mixture on top, spreading it around evenly with the back of a spoon. Sprinkle flaky sea salt on top, if you like.
  • Place the pan in the freezer to firm up. Once they are firm (about 10 minutes or so), they are ready to enjoy. Transfer to an airtight container to preserve their flavor and store them in the fridge for up to 1 month. Serve chilled for the best texture; these can melt in your hands if they warm up too much.

Notes

Nutrition information is for 1 peanut butter cup, assuming you use all of the melted chocolate (you might not!) and get 9 cups from this batch. This information is automatically calculated so it’s just an estimate, not a guarantee.
Want to make a holiday shape? Turn this recipe into Peanut Butter Hearts or Peanut Butter Eggs, instead. (See the linked posts for a photo tutorial.)
Chocolate Chip Note: For a lower calorie treat, you can reduce the dark chocolate chips to only 1/4 cup. In this case, you’ll only be able to coat the top of each peanut butter cup. (Not the bottom and sides.) So, start by pressing the peanut butter filling into the bottom of the muffin cup, then add chocolate to only the top.
Dairy-Free Note: This recipe is dairy-free when you use allergy-friendly chocolate chips, such as Enjoy Life brand.
