Sugar Cookie Bars

  • 1 lb packaged sugar cookie dough

Buttercream Frosting

  • 1 cup unsalted butter softened to room temp
  • cups powdered sugar
  • ½ cup unsweetened cocoa powder
  • 3 tbsp milk*
  • ¼ tsp salt
  • 2 tsp vanilla extract


  • Preheat oven to 350°. Let dough stand at room temperature 5-10 minutes to soften. Cut into 1/2" slices. With floured hands (or the bottom of a drinking glass), press dough into an even layer in a greased 13X9 pan. Bake 18-20 minutes or until lightly browned and edges are firm. Allow to cool slightly.
  • With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy – about 2 minutes. Add confectioners’ sugar, cocoa powder, milk, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high speed and beat for 1 full minute. Add 1/4 cup more powdered sugar if frosting is too thin or another tbsp of milk if frosting is too thick.
  • Evenly spread frosting over sugar cookie bars. Allow to set and serve. Store in the fridge, but allow to come to room temperature for the best tasting treat.


  • IF MAKING FROSTING FOR LATER: Cover tightly and store for up to 1 week in the refrigerator or up to 3 months in the freezer. After freezing or refrigerating, thaw in the refrigerator, bring to room temperature then beat the frosting for a few seconds so it’s creamy again. You may need to add a little milk if it’s still too stiff.
