Note-the above ingredients can be modified a little. If your frosting seems dry, add a little more milk. If it seems too wet, add a little powdered sugar.
Mix ingredients together until smooth. Put in a ziplock bag and snip off the corner. Pipe frosting onto a cookie and then spread with a knife. Sprinkle with crushed Reese’s Peanut Butter Cups.
I hope you love these chocolate Reese’s peanut butter cup cookies as much as I do! So yummy!
