Ingredients

Scale
  • 2 ¾ cups (345 g) all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (227 g) unsalted butter, softened
  • 1 ½ cups (300 g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons whole milk
  • 2 ½ cups (315 g) powdered sugar
  • 23 tablespoons heavy cream
  • 1 teaspoon vanilla extract (for frosting)
  • Optional sprinkles or sanding sugar

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper.
  2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  3. In a large bowl, use an electric mixer to cream the softened butter and granulated sugar on medium speed for 3-4 minutes until light and fluffy.
  4. Add eggs one at a time, beating well after each addition, then mix in 2 teaspoons vanilla extract.
  5. Gradually add the dry ingredients to the wet mixture and mix on low speed just until combined. Avoid overmixing.
  6. Stir in the whole milk.
  7. Spread the batter evenly in the prepared baking pan using a rubber spatula.
  8. Bake for 28-32 minutes or until edges are golden and a toothpick inserted in the center comes out with a few moist crumbs.
  9. Remove from oven and cool completely on a wire rack (about 1 hour).
  10. To make frosting, beat 1 cup softened unsalted butter until creamy. Gradually add powdered sugar, mixing on low speed.
  11. Add heavy cream and 1 teaspoon vanilla extract, then beat on high for 3-4 minutes until light and fluffy. Adjust cream to desired consistency.
  12. Spread frosting evenly over cooled bars. Add sprinkles or sanding sugar if desired.
  13. Cut into bars with a sharp knife, cleaning the knife between cuts for neat edges.
  14. Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.

Notes

Use softened unsalted butter for best texture and flavor. Avoid overmixing the batter to keep bars tender. Chill dough slightly before baking for a more tender crumb. Frost only when bars are completely cooled to prevent melting. Use a warm knife for clean cuts.
