Ingredients

Scale

Cookie Layer

  • 1/2 cup butter, softened
  • 1/2 cup granulated sugar
  • 2 tbsp brown sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 1/2 tsp baking powder
  • 1 1/4 cup all-purpose flour
  • 1/4 tsp salt

Frosting

  • 4 tbsp butter, softened (salted or unsalted)
  • 1 cup powdered sugar
  • 2 tbsp heavy cream
  • 1 tsp vanilla extract
  • Pink gel food coloring (optional)
  • Purple gel food coloring (optional)
  • Valentine’s Day sprinkles

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper or aluminum foil to prevent sticking and for easy removal of the bars.
  2. Make the Cookie Batter: In a large bowl, cream together the butter, granulated sugar, and brown sugar until the mixture is smooth and creamy. Add in the egg and vanilla extract, mixing well until fully incorporated.
  3. Incorporate Dry Ingredients: Gently mix in the all-purpose flour, baking powder, and salt just until the flour mixture barely disappears, avoiding overmixing to keep the cookie bars tender.
  4. Bake the Cookie Layer: Spread the batter evenly into the prepared baking pan and bake for 15 minutes. The center may still look slightly raw, but it will continue baking as the bars cool, so do not overbake.
  5. Prepare the Frosting: In a large bowl, whip the softened butter and powdered sugar together until combined. Add the heavy cream and vanilla extract, then whip until the frosting is light and fluffy.
  6. Color the Frosting: For a marbled effect, divide the frosting into two bowls. Color one with the pink gel food coloring, and the other with the purple gel food coloring. Mix each gently until the color is evenly distributed.
  7. Decorate the Bars: Dollop the pink and purple frosting alternately over the cooled cookie bars. Using a spatula or toothpick, gently swirl to create a marbled look. Sprinkle Valentine’s Day sprinkles over the top.
  8. Set or Serve: You can enjoy the bars immediately for a soft frosting texture, or chill them to allow the frosting to set firmer before slicing and serving.

Notes

  • Do not overbake the cookie layer; it should look slightly underbaked in the center when removed from the oven.
  • Use softened butter for both the cookie dough and frosting to ensure smooth mixing and fluffy texture.
  • Gel food coloring is preferred for vibrant color without altering the frosting consistency.
  • Allowing the bars to chill will make frosting easier to slice cleanly.
  • Store leftover bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
