How to Make It
Follow these simple steps to create your delicious cookie bars:
Preheat oven
Preheat your oven to 350°F (175°C) and prepare a baking dish by lining it with parchment paper.
Mix wet ingredients
In a mixing bowl, cream together 1/2 cup butter, granulated sugar, and brown sugar until light and fluffy. Add the egg, 2 teaspoons of vanilla extract, and almond extract (if using), mixing until well combined.
Combine dry ingredients
In a separate bowl, whisk together the baking powder, all-purpose flour, cornstarch, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined.
Bake the bars
Spread the cookie batter evenly into the prepared baking dish. Bake for 15-18 minutes or until the edges are lightly golden and a toothpick inserted in the center comes out clean. Let cool completely in the dish.
Prepare the frosting
In another bowl, beat together 4 tablespoons of softened butter, powdered sugar, 1 teaspoon of vanilla extract, and heavy cream until smooth and fluffy. Adjust the consistency with more cream if necessary.
Frost the bars
Once the cookie layer has cooled, spread the frosting evenly over the surface. Top with patriotic sprinkles to make them festive.
How to Store It
Fridge: store in an airtight container for up to 7 days.
