How to Make 4 Ingredient Peanut Butter Cups
Ingredients
- 1/2 cup Powdered Peanut Butter
- 1 scoop Protein Powder
- 1/2 cup Water
- 1 cup Dark Chocolate Chips
- 1 tbsp Coconut Oil
Directions
- Prepare the Molds: Line a muffin tin with 8 cupcake liners and set aside.
- Prepare Peanut Butter Filling: In a small bowl, combine powdered peanut butter and protein powder. Gradually add water and mix until the filling reaches a slightly thick yet smooth texture. Set aside.
- Melt the Chocolate: Combine chocolate chips and coconut oil in a microwave-safe bowl. Microwave for 45 seconds, stir, then microwave again for 30 seconds and mix until fully melted and smooth.
- Make the First Layer: Add a tablespoon of melted chocolate to each cupcake liner. Tilt, rotate, and shake the liners to coat the bottom evenly, and use a spoon to cover a bit of the sides as well. Place the muffin tin in the freezer for about 10 minutes to set.
- Add Peanut Butter Layer: Remove the muffin tin from the freezer. Using an ice cream scooper or a tablespoon, add a tablespoon of the peanut butter mixture over the set chocolate layer, spreading it evenly with the back of a spoon.
- Top It Off: Spoon another tablespoon of melted chocolate over each peanut butter layer, spreading it to the edges to seal the peanut butter inside. If desired, sprinkle sea salt.
- Chill to Set: Refrigerate the peanut butter cups for at least 30 minutes or until they are completely firm. Once set, remove the peanut butter cups from the liners and enjoy.

No, regular peanut butter will not work the same way. Powdered peanut butter helps keep the filling texture light and easy to spread.
2. Is it possible to make these peanut butter cups vegan?
Yes! Substitute the chocolate chips with dairy-free chocolate and make sure your protein powder is plant-based.
3. Can I add sweeteners to the peanut butter filling?
Absolutely! You can add honey, maple syrup, or your preferred sweetener to the peanut butter filling if you want it sweeter.
