Step by Step Instructions

For the Cupcakes

Step 1 – Preheat the oven to 350 degrees Fahrenheit and line 2 muffin tins with cupcake liners.

Step 2 – In a large mixing bowl, whisk together the flour, baking powder, baking soda and salt. Set aside.

Step 3 – In a separate mixing bowl, whisk together the creamy peanut butter, brown sugar, egg, sour cream, milk and vanilla extract.

Step 4 – Create a well in the flour mixture and pour the wet ingredients into the dry ingredients. Stir until combined.

Step 5 – Pour the batter into the cupcake liners filling them up approximately 2/3 of the way full. Bake for 20-23 minutes until a toothpick inserted into the center of the cupcakes comes out clean.

Step 6 – Cool the cupcakes completely on a wire rack before topping with the frosting.

For the Frosting

Step 7 – In a medium bowl, cream together butter and peanut butter until smooth and fluffy with a hand held or stand up mixer.

Step 8 – Gradually add powdered sugar, alternating with milk, beating after each additional until desired consistency.

Step 9 – Pipe the frosting on to the cooled cupcakes, top with a piece of the peanut butter cups and then they are ready to serve and enjoy.

Recipe Tips

Room Temperature Ingredients – Before combining the ingredients we recommend egg and butter come to room temperature. This helps to create a smooth and creamy texture.
Filling Cupcake Liners – Fill the cupcake liners about 2/3 full to prevent the cupcake from spilling over the side. We recommend evenly distribute the batter so that the cupcakes are about the same size.
Cool Cupcakes – Before frosting the cupcakes make sure they have cooled to room temperature.
Piping Frosting – You can spread the frosting on with a knife or pipe it on with piping bags. We like to use a piping bag when we are taking them to a family gathering.
