Cookie Butter Cupcakes

I am obsessed with cookie butter! So naturally, I decided that I should make cookie butter cupcakes!  I went with chocolate cupcakes, chocolate ganache filling, and cookie butter buttercream.

• 1/2 cup cookie butter (I got mine from Whole Foods)
• 1 stick of room temperature butter
• 2 cups of confectioners sugar (add a bit more if consistency is not thick enough)
• 1 tbs milk
• Mix butter and cookie butter first and then mix the remaining ingredients in a mixer on low and then on medium speed until well combined.
