Ingredients you will need
Below is a list of ingredients you will need to make these peanut butter cups. Full measurements are listed down below in the recipe card.

- Creamy peanut butter: I love using peanut butter for this, but you can also use almond butter or any other nut butter.
- Protein powder: I use Whey Protein and vanilla flavor, but you can use any other protein powder. For a vegan option, use plant-based protein powder.

- Coconut oil helps thin out the chocolate and prevents it from becoming too hard when it sets.
How to make protein peanut butter cups
Below is a step-by-step process on how to make these protein peanut butter cups.

1️⃣ Make the peanut butter filling
Place 6 paper liners in the wells of a muffin tin and set aside. In a small bowl, mix the protein powder and peanut butter until smooth.
✏️ Using silicone liners will make it easier to peel the peanut butter cups off the liner. Other paper liners will work, but some may stick.
2️⃣ Melt the chocolate
Place the chocolate chips and coconut oil in a bowl; microwave in 30-second increments until fully melted. Add approximately 1 tablespoon of melted chocolate to the bottom of each liner.
Place the muffin tin in the freezer for 10 minutes or until the chocolate is set.

3️⃣ Add the peanut butter filling
Place 2 teaspoons of the peanut butter mixture on top of the chocolate layer. Spread them out a bit.
✏️ You should make sure the chocolate at the bottom has hardened.
4️⃣ Top the filling with chocolate and cool
Add an additional tablespoon of chocolate on top of the peanut butter mixture. Chill until firm.
✏️ Once they are fully set, you can remove them from the silicone cups and place them in a container. Store in the refrigerator until ready to serve.
