These yummy Protein Peanut Butter Cups are the perfect treat for a sweet tooth and a protein boost! Creamy peanut butter wrapped in chocolate makes for a delightful snack.
Whenever I make these, I can’t resist sneaking a few bites before they’re fully set! 😋 They’re so easy to whip up, making snack time both tasty and fun!
Key Ingredients & Substitutions
Peanut Butter: Natural creamy peanut butter works best here. If you’re looking for a nut-free alternative, try sunflower seed butter or almond butter. Just check that they’re smooth and unsweetened!
Protein Powder: Use your favorite vanilla or unflavored protein powder. If you’re dairy-free, a plant-based protein option is a great substitute. I like to use a blend for a balanced flavor.
Coconut Flour: This is optional but can help with thickness. If you don’t have coconut flour, you can omit it or use almond flour instead, but adjust the amount as you may need less.
Sweetener: Honey gives a nice touch of sweetness, but maple syrup works too if you want a vegan option. You can always adjust the amount based on your sweetness preference.
Dark Chocolate: You can swap dark chocolate chips with semi-sweet chocolate for a sweeter taste or even use dairy-free chocolate chips. Just ensure they melt well!
How Do I Melt Chocolate Without Burning It?
Melted chocolate is a key component, but it can burn easily! Here are some tips for melting it smoothly:
- Use a double boiler: Place a heatproof bowl on top of a saucepan with simmering water. Make sure the bowl doesn’t touch the water.
- Microwave method: Heat chocolate in a microwave-safe bowl at 50% power, stirring every 30 seconds until smooth. This prevents overheating.
Whichever method you choose, be patient and stir as you go; this keeps the chocolate nice and soft. Happy melting!

How to Make Protein Peanut Butter Cups
Ingredients You’ll Need:
- 1 cup natural creamy peanut butter (no sugar added)
- 1/4 cup vanilla or unflavored protein powder (whey or plant-based)
- 2 tablespoons coconut flour (optional, for thickness)
- 2 tablespoons honey or maple syrup (for sweetness)
- 1/2 teaspoon vanilla extract
- 1 1/2 cups dark chocolate chips (or chopped dark chocolate)

How Much Time Will You Need?
This quick and easy recipe takes about 15 minutes for preparation, plus an additional 30 minutes to set in the fridge or freezer. So, in about 45 minutes, you can enjoy these healthy and delicious Protein Peanut Butter Cups!
Step-by-Step Instructions:
1. Mix the Peanut Butter Filling:
In a medium bowl, combine the peanut butter, protein powder, coconut flour (if you’re using it), honey or maple syrup, and vanilla extract. Stir well until everything is mixed into a thick, moldable dough. If it feels too soft, just add a little more coconut flour to get it to your desired thickness!
2. Prepare the Muffin Tin:
Line a muffin tin with paper or silicone cupcake liners. This will make it easy to remove the peanut butter cups once they’re set!
3. Melt the Chocolate:
In a double boiler, melt the dark chocolate chips and coconut oil together. If you prefer, you can also do this in the microwave. Heat the chocolate in a microwave-safe bowl in 30-second increments, stirring each time until smooth. Be careful not to burn it!
4. Assemble the Cups:
Spoon about 1 tablespoon of the melted chocolate into the bottom of each liner. Tilt the pan gently to ensure the chocolate spreads evenly. Pop the muffin tin in the freezer for about 5 minutes to let the chocolate set.
5. Fill with Peanut Butter Mixture:
Once the chocolate is hardened, take the peanut butter mixture and form small balls or discs that will fit inside each cup. Press each piece gently into the chocolate layer until it’s snug.
6. Top with More Chocolate:
Now it’s time to cover the peanut butter layer! Spoon another tablespoon of melted chocolate over each cup, ensuring the peanut butter is completely covered.
7. Add Flaky Sea Salt:
For a tasty finishing touch, sprinkle a pinch of flaky sea salt on top of each cup. This will add a yummy contrast to the sweetness!
8. Chill and Set:
Place the muffin tin back in the fridge or freezer for at least 30 minutes, or until fully set. This is the hard part—waiting!
9. Store and Enjoy:
Once the cups are set, you can store them in an airtight container in the fridge for up to a week. Enjoy these delightful treats any time you need a protein-packed snack!
These Protein Peanut Butter Cups are a perfect balance of creamy and crunchy, sweet and salty! Enjoy every bite!
Can I Use Other Nut Butters?
Absolutely! Any nut or seed butter can be substituted for peanut butter, such as almond butter or sunflower seed butter. Just ensure they are creamy for the best texture!
How Can I Make These Vegan?
To make these protein peanut butter cups vegan, use maple syrup in place of honey, choose a plant-based protein powder, and opt for dairy-free dark chocolate. You’ll still get that delicious taste!
Can I Freeze the Peanut Butter Cups?
Yes, you can freeze them! Place the cups in an airtight container and freeze for up to 3 months. Just let them sit at room temperature for a few minutes before enjoying to soften slightly.
What Do I Do If My Chocolate Is Too Thick?
If your melted chocolate is too thick, add a bit more coconut oil while melting. This will help achieve a smoother, pourable consistency, making it easier to coat the cups.
