  • Brown Sugar: ½ cup
  • Granulated Sugar: ½ cup
  • Large Egg: 1
  • Vanilla Extract: ½ teaspoon
  • Mint Extract: ½ teaspoon
  • All-Purpose Flour: 2 ½ cups
  • Baking Powder: 1 teaspoon
  • Salt: ½ teaspoon
  • Green Gel Color: as needed

For the Frosting:

  • Unsalted Butter: ½ cup, softened
  • Vanilla Extract: ½ teaspoon
  • Mint Extract: ½ teaspoon
  • Salt: ¼ teaspoon
  • Powdered Sugar: 3 ½ cups
  • Heavy Whipping Cream: 6 tablespoons
  • Green Sanding Sugar: for topping

  1. Prepare the Cookie Base: Preheat oven to 375°F. Line a 9×13 pan with foil and spray with nonstick spray. Beat butter and sugars until creamy. Mix in egg and extracts.
  2. Mix Dry Ingredients: Combine flour, baking powder, and salt. Gradually add to the butter mixture until a stiff dough forms. Color the dough with green gel to desired shade.
  3. Bake: Press the dough into the prepared pan and bake for 14 minutes. Let cool completely.
  4. Make the Frosting: Beat butter, extracts, and salt until creamy. Alternately add powdered sugar and cream, beating until light and fluffy.
  5. Decorate: Spread frosting over cooled bars. Sprinkle with green sanding sugar and top each bar with a dried cherry.


  • Soften butter to room temperature for easier creaming.
  • Add food coloring gradually to reach the desired shade without oversaturating the dough.
  • Ensure cookie base is completely cool before frosting to prevent melting.
  • Dry cherries thoroughly to prevent sugar from dissolving.


  • Can I use peppermint extract instead of mint extract? Yes, peppermint extract will give a stronger, more seasonal flavor.
  • How do I store these bars? Keep them in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • Can I freeze the cookie bars? Yes, freeze them without the frosting for up to 3 months and add frosting after thawing.
