Peanut Butter Frosting

• 2 cups powdered sugar
• 1/2 cup unsalted butter, softened

Grease or line a 9" round cake pan with parchment paper. Set aside.

In the bowl of a stand mixer, cream the butter/coconut oil, sugars, and the peanut butter until combined. Add the egg, milk, and vanilla extract and beat until smooth. Add the salt, baking soda, and flour. Mix until combined. Press into prepared cake pan, then refrigerate for 30 minutes. 

Preheat the oven to 350 F.

When dough is cold, bake for 20 to 25 minutes, or until golden brown and a toothpick comes out clean with just a few moist crumbs. Allow to cool completely.

For the frosting, add the butter and peanut butter to the bowl of a stand mixer. Cream together, then slowly mix in the powdered sugar. Add milk as needed until desired consistency. 

Frost cookie cake as desired. Slice and enjoy!
