Protein Peanut Butter Cups are a yummy treat that packs a punch of flavor and energy! These little cups combine creamy peanut butter with rich chocolate, making them a real delight.
They’re so simple to make that you’ll want to whip up a batch every week. I love popping one in my bag for a quick snack on the go—who wouldn’t want chocolate and peanut butter in their life? 😋
Key Ingredients & Substitutions
Natural Peanut Butter: Go for creamy and unsweetened peanut butter for a smooth texture. If you’re allergic, try almond or sunflower seed butter instead. Nut butters provide healthy fats and protein.
Protein Powder: I love using vanilla or unflavored protein powder here. For a dairy-free option, choose plant-based protein. You can even swap it with a scoop of powdered peanut butter for a lighter touch!
Sweetener: Maple syrup gives a nice flavor, but honey works too. If you’re vegan, stick with maple syrup or try agave nectar. Adjust the amount based on your sweetness preference.
Chocolate: Dark chocolate is my go-to for a rich taste. If you want a sweeter cup, semi-sweet chocolate chips work too. For a slightly decadent option, white chocolate can also be used, though it’ll change the flavor.
How Do I Get the Chocolate to Melt Smoothly?
Melted chocolate can be tricky, but it’s totally manageable. Here’s how to make it smooth:
- Use a microwave-safe bowl and microwave in short bursts (20-30 seconds), stirring in between. This prevents it from burning.
- Adding coconut oil helps keep the chocolate silky. It’s optional, but it really does enhance the texture!
- If using a double boiler, heat water in a pot and place a bowl over it, stirring until melted.
Always be patient — it’s worth it for the smooth chocolate that’ll perfectly coat these cups!
How to Make Protein Peanut Butter Cups
Ingredients You’ll Need:
For the Peanut Butter Filling:
- 1 cup natural peanut butter (creamy, unsweetened)
- 1/4 cup vanilla or unflavored protein powder (whey or plant-based)
- 2 tablespoons maple syrup or honey (adjust to taste)
- 1/2 teaspoon vanilla extract

How Much Time Will You Need?
This yummy recipe takes about 15 minutes to prepare and an additional 30-40 minutes to chill in the fridge or freezer. So in total, you’re looking at about an hour before they’re ready to enjoy!
Step-by-Step Instructions:
1. Prepare the Muffin Tin
Start by lining a muffin tin with mini paper cupcake liners or use silicone molds. This will make it easy to pop out the cups later.
2. Make the Peanut Butter Filling
In a medium bowl, combine the peanut butter, protein powder, maple syrup or honey, vanilla extract, and a pinch of salt. Stir everything together until you form a thick and pliable mixture. Feel free to adjust the sweetness to your liking!
3. Melt the Chocolate
In a microwave-safe bowl, add the dark chocolate chips and coconut oil (if using). Microwave them in 20-30 second intervals, stirring well each time until everything is smooth and melted. Be careful not to overheat!
4. Assemble the Bottom Layer
Spoon about 1 teaspoon of the melted chocolate into the bottom of each cupcake liner. Use the back of the spoon to spread and cover the base evenly.
5. Freeze the First Layer
Place the muffin tin in the freezer for about 5-7 minutes, or until the chocolate layer has hardened. You want it firm enough to hold up the filling.
6. Add the Peanut Butter Filling
Take a small amount (about 1 tablespoon) of the peanut butter mixture and form it into a disc or ball. Gently press it on top of the hardened chocolate in each cup.
7. Seal with More Chocolate
Pour another teaspoon of melted chocolate over each peanut butter filling, smoothing it out with the back of the spoon to seal the cups.
8. Sprinkle with Sea Salt
Finish by sprinkling a pinch of flaky sea salt over each cup for that extra flavor kick!
9. Chill Until Set
Refrigerate or freeze the cups for at least 30 minutes or until they are fully set and firm. This is the hardest part, but it will be worth the wait!
10. Store and Enjoy!
Once set, store your protein peanut butter cups in an airtight container in the fridge for up to a week, or in the freezer for longer storage. Now, enjoy every rich and satisfying bite!
Can I Use Crunchy Peanut Butter Instead of Creamy?
Absolutely! Crunchy peanut butter will add a nice texture to the cups. Just make sure it’s natural and unsweetened for the best flavor!
How Can I Make These Peanut Butter Cups Vegan?
To make them vegan, simply use maple syrup in place of honey and ensure your chocolate is dairy-free. Many brands have delicious vegan dark chocolate options!
Can I Use a Different Type of Sweetener?
Yes! You can substitute maple syrup or honey with agave nectar or stevia, but keep in mind that stevia is much sweeter, so start with a smaller amount and adjust to taste.
How Do I Store the Peanut Butter Cups?
Store them in an airtight container in the fridge for up to a week, or freeze them for longer preservation. Just remember to separate layers with parchment paper if you stack them!
