In medium bowl add butter and peanut butter. Beat until smooth. Add vanilla and combine.
Add powdered sugar and beat slowly until combined. Add milk and beat until consistency of creamy frosting. (May need to add more milk. If so add one tablespoon at a time.)
Put peanut butter cream into frosting bag using the tip of your choice. Set aside.
Using a small circular cookie cutter, cut 8-10 small circles out of the KING’S HAWAIIAN Chocolate Dobash Hawaiian Swirl. (Eat the remaining scraps!)
Apply frosting to the tops of the Hawaiian Swirl circles.
Garnish with chopped nuts for added visual and texture.
