Ingredients
  

  • For the Cookie Base:
  • 2 ½ cups all-purpose flour
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 10 tablespoons unsalted butter softened
  • 1 cup granulated sugar
  • 1 large egg
  • 1 egg white
  • 1 ½ tablespoons sour cream
  • 1 teaspoon vanilla extract
  • ½ teaspoon almond extract optional
  • For the Buttercream Frosting:
  • 4 tablespoons butter softened
  • 1 ½ ounces cream cheese softened
  • ½ teaspoon vanilla extract
  • 2 cups powdered sugar
  • 2 tablespoons heavy cream or milk
  • Food coloring and sprinkles optional

Instructions
 

  • Preheat the oven to 375°F and grease or line a 9x13 inch baking pan with parchment paper.
  • Whisk together the flour, baking powder, and salt in a medium bowl and set aside.
  • In a large bowl, cream the softened butter and granulated sugar with an electric mixer until pale and fluffy.
  • Add the egg, egg white, sour cream, vanilla, and almond extract, mixing until smooth.
  • Slowly mix in the dry ingredients on low speed just until combined, being careful not to overmix.
  • Press the dough evenly into the prepared pan using a spatula or damp fingers.
  • Bake until the edges are set and a toothpick comes out clean, then let the bars cool completely in the pan.
  • Prepare the frosting by beating the butter and cream cheese until creamy, then adding vanilla and powdered sugar.
  • Mix in the cream or milk until fluffy, adding food coloring if desired.
  • Spread the frosting over the cooled bars, add sprinkles, and slice into squares.

Notes

• Measuring Flour: Always use the spoon and level method to avoid dry, crumbly bars.
• Don't Overbake: Pull the bars out of the oven when they look matte and soft; they will firm up as they cool.
• Clean Cuts: For the neatest squares, chill the frosted bars in the refrigerator for about 20 minutes before slicing with a clean, warm knife.
• Storage: Keep leftovers in an airtight container in the refrigerator for up to 5 days.
