What’s great is that you can enjoy dessert without the guilt! I love snacking on these after a workout or whenever I need a sweet boost during the day. Yum!
Key Ingredients & Substitutions
Natural Peanut Butter: Choose creamy or crunchy based on your texture preference! If you’re looking for nut-free options, almond butter or sunflower seed butter work well as substitutes.
Protein Powder: I use vanilla flavored for a little sweetness. If you want to avoid it, you can replace it with ground oats or skip it entirely, although that may change the texture a bit.
Honey or Maple Syrup: Both sweeteners add great flavor! If you’re vegan, stick with maple syrup. You can also use agave or a sugar-free alternative if desired.
Dark Chocolate: For that rich flavor, I recommend at least 70% cocoa. If you’re looking to reduce sugar, try unsweetened chocolate or a lighter chocolate. Just adjust the sweeteners accordingly!
How Do I Get the Perfect Chocolate Coating?
Melted chocolate can be tricky, so here’s how to get it just right:
- Use a microwave-safe bowl, and melt the chocolate in short bursts of 30 seconds to avoid burning.
- Stir between each heating to help the chocolate melt evenly. Get it to a smooth consistency!
- When you spoon the chocolate into the muffin tin, gently tap it on the counter. This helps the chocolate spread evenly and prevents air bubbles.
Following these tips will give you a nice smooth coating and a beautiful finish to your Peanut Butter Cups!

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and another 35 minutes for chilling. You’ll be able to enjoy delicious homemade Protein Peanut Butter Cups in under an hour!
Step-by-Step Instructions:
1. Prepare the Peanut Butter Mixture:
In a medium bowl, combine the natural peanut butter, protein powder, honey (or maple syrup), vanilla extract, and salt (if using). Mix everything together until it’s smooth and well blended. This will be the creamy filling for your cups!
2. Prepare the Muffin Tin:
Grab a mini muffin tin and line it with paper or silicone cupcake liners. This will make it easy to remove the cups once they’re set. You can also lightly spray the liners with cooking spray to ensure easy removal.
3. Melt the Chocolate:
In a microwave-safe bowl, melt the dark chocolate chips. Heat them in 30-second intervals, stirring well between each session until the chocolate is fully melted and smooth. Be careful not to burn the chocolate!
4. Create the Chocolate Base:
Using a spoon, pour about 1 teaspoon of melted chocolate into the bottom of each muffin liner. Gently tap the muffin tin on the counter to spread and flatten the chocolate layer evenly.
5. Chill the Chocolate Base:
Place the tin in the freezer for about 5 minutes. This will allow the chocolate layer to firm up nicely.
6. Add the Peanut Butter Layer:
After chilling, take the muffin tin out of the freezer. Spoon about 1 tablespoon of the peanut butter mixture on top of the hardened chocolate layer in each liner. Use the back of your spoon to flatten it into an even layer.
7. Cover with More Chocolate:
Now, take another teaspoon of the melted chocolate and pour it over the peanut butter layer, making sure to cover it completely. This will give you that delicious chocolatey top!
8. Finish with Sea Salt:
Sprinkle a small pinch of sea salt flakes on top of each cup for an extra flavor pop. This step is totally optional, but trust me, it adds a delightful touch!
9. Freeze to Set:
Put the muffin tin back into the freezer for at least 30 minutes so the peanut butter cups can fully set. You’ll know they’re ready when they’re firm to the touch.
10. Enjoy!
Once set, carefully remove the cups from the liners. Store them in an airtight container in the refrigerator if you want them soft and chewy, or in the freezer if you enjoy them chilled. Enjoy these incredible Protein Peanut Butter Cups as a high-protein snack or dessert any time you like!
Can I Use Almond Butter Instead of Peanut Butter?
Absolutely! Almond butter is a great alternative if you’re looking for a different flavor or if you have a peanut allergy. Just keep in mind that it may alter the taste slightly, but it will still be delicious!
How Should I Store Leftover Peanut Butter Cups?
Store leftover Protein Peanut Butter Cups in an airtight container. They can be kept in the refrigerator for about a week or in the freezer for several months. Just make sure to separate layers with parchment paper to prevent sticking.
Can I Use Milk Chocolate Instead of Dark Chocolate?
Yes, you can! Milk chocolate will give a sweeter flavor, but keep in mind that it will also increase the sugar content. If you love that sweet contrast with the peanut butter, go for it!
What If the Peanut Butter Filling Is Too Sticky?
If your peanut butter filling turns out too sticky, you can add a bit more protein powder to help with the texture. Adding a pinch of powdered sugar can also help if you’re looking for a sweeter option. Just mix until you reach your desired consistency!
