Key Ingredients & Substitutions
Natural Creamy Peanut Butter: Use peanut butter with no added sugar for a healthier option. If you’re allergic to peanuts, almond butter or sunbutter are great substitutes. Just keep an eye on the texture; you want a smooth, creamy consistency.
Protein Powder: I like vanilla protein powder for a bit of sweetness. If you prefer chocolate-flavored or have dietary needs, plain or plant-based protein powders work too. Just note that flavor and sweetness may vary.
Sweetener: Honey or maple syrup adds sweetness. For a low-calorie option, sugar-free maple syrup works well. If you’re vegan, stick to maple syrup or agave nectar.
Dark Chocolate: I use dark chocolate chips (70% cocoa) for a rich taste. Milk chocolate or dairy-free chocolate chips can be alternatives, but they will change the flavor profile.
How Do I Melt Chocolate Without Burning it?
Melting chocolate can be tricky, but with the right technique, it’s easy. Here are a few tips to get it right:
- Use a microwave-safe bowl. Microwave in 30-second intervals. Stir in between to help even out the heat.
- If using a double boiler, place the bowl above simmering water. Stir continuously until melted, but avoid water getting into the chocolate.
- Remove from heat as soon as it’s mostly melted. The residual heat will finish melting the chocolate without burning it.
Following these steps will give you smooth melted chocolate for your cups. Enjoy your homemade treats!

Protein Peanut Butter Cups
Ingredients You’ll Need:
For The Filling:
- 1 cup natural creamy peanut butter (no added sugar)
- 1/4 cup vanilla or unflavored protein powder
- 2 tablespoons honey or maple syrup
- 1/4 teaspoon sea salt, plus extra for topping
For The Chocolate Coating:
- 1 1/2 cups dark chocolate chips or chopped dark chocolate (70% cocoa or higher)
- 1 tablespoon coconut oil (optional, for smoother chocolate)
How Much Time Will You Need?
This recipe takes around 15 minutes for preparation and about 30 minutes in the freezer to set. Ideal for a quick-and-easy treat!
Step-by-Step Instructions:
1. Prepare the Cups:
Start by lining a muffin tin or small silicone molds with cupcake liners. This will make it easy to take the cups out once they are set.
2. Make the Peanut Butter Mixture:
In a mixing bowl, mix together the peanut butter, protein powder, honey (or maple syrup), and 1/4 teaspoon of sea salt. Stir until the mixture is smooth and well combined. If it’s too thick, you can microwave it for about 10-15 seconds to make it easier to mix.
3. Melt the Chocolate:
In a microwave-safe bowl, melt the dark chocolate and coconut oil together. Do this in 30-second intervals, stirring in between each interval until the chocolate is smooth. If you prefer, you can also melt the chocolate using a double boiler.
4. Create the Base:
Spoon about 1 teaspoon of the melted chocolate into each cupcake liner, spreading it evenly to cover the bottom. Once all the bases are done, place the tray in the freezer for about 5 minutes to allow the chocolate to set.
5. Add the Peanut Butter Layer:
Remove the tray from the freezer and scoop about 1 tablespoon of the peanut butter filling on top of the set chocolate layer. Gently press it down to create an even layer.
6. Top with More Chocolate:
Next, spoon another teaspoon of melted chocolate over the peanut butter filling, ensuring it is completely covered.
7. Sprinkle for Flavor:
For that extra touch, sprinkle a pinch of flaky sea salt on top of each cup.
8. Final Chill:
Return the molds to the freezer and chill for at least 30 minutes, or until the chocolate is fully hardened.
9. Enjoy Your Treats:
Once set, carefully remove the peanut butter cups from the liners. Store them in an airtight container in the refrigerator for up to 1 week. Enjoy these delicious and protein-packed treats anytime you need a snack!
Can I Use Natural Peanut Butter with Added Sugar?
It’s best to stick with natural creamy peanut butter that has no added sugar to keep these cups healthier. However, if you prefer a sweeter taste, you can use peanut butter with sugar; just reduce the amount of honey or maple syrup in the recipe.
Can I Substitute the Protein Powder?
Yes, you can use any type of protein powder including whey, soy, or pea protein. If you’re looking for a lower calorie option, consider using a sugar-free protein powder. Just remember that the flavor may change slightly based on your choice.
How Can I Make These Vegan-Friendly?
To make these cups vegan, use maple syrup instead of honey and ensure you’re using dairy-free dark chocolate or chocolate chips. Most brands offer suitable options!
What if I Don’t Have Coconut Oil?
You can skip the coconut oil; it’s optional for making the chocolate smoother. Just be careful when melting the chocolate to avoid burning it. If you notice it getting thick, reduce heat and stir often!
