I'm a sucker for chocolate and peanut butter together, which inspired this super easy and delicious filling for cakes and cupcakes alike. You simply throw all of the ingredients in a bowl together and mix, then it's ready to use; it can't get any easier than that! My favorite way to use this is in the center of my favorite chocolate cupcakes...so yum!
Ingredients:
8 tbsp butter, melted
272g (2 cup + 4 tbsp) powdered sugar
400g (2 heaping cups) Peanut Butter
2 tsp vanilla extract
¾ tsp salt
1 tbsp milk
Directions:
Combine all ingredients in a medium bowl and mix together with a spatula. Once ingredients are mostly incorporated, whisk vigorously to remove lumps. The mixture may still be lumpy, but that's okay. If you're looking for a completely smooth filling, I recommend using an electric mixer with a paddle attachment.
Use in between cake layers or to fill the centers of cupcakes. Ensure the cakes are completely cooled before filling.
