Step 1

Preheat the oven to 350F then line a baking sheet with parchement paper and set aside.

Step 2

Cream butter, brown sugar, and granulated sugar until light and creamy. Mix in the egg and the vanilla extract until combined.

Step 3

Add the flour, cocoa powder, baking soda, and salt and mix until the flour mixture disappears. Scoop out 7 equally sized cookie dough balls with a large cookie scooper (about 1/4 cup), and place those cookies on a baking sheet leaving about 2 inches of space between each one.

Step 4

Gently press down on the cookies to about 1 inch in thickness, and bake in the preheated oven for 10 minutes. Once the cookies are baked, let them cool down on the baking sheet for 10 minutes before transferring them to a cooling rack.

Step 5

In a medium bowl, whisk the peanut butter, butter, powdered sugar, and vanilla until a thick paste forms.

Step 6

Divide the peanut butter mixture into 7 little balls, top each cooled-down cookie with a peanut butter ball, and press down gently to flatten.

Step 7

Melt the semi-sweet chocolate chips, and top each cookie with it. Spread the melted chocolate and serve.
