01 - Preheat oven to 350°F. Grease and line a 9x13 inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking powder, and salt until well incorporated.
03 - In a large bowl, cream butter and sugar together with a mixer until light and fluffy, approximately 2-3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract and almond extract until combined.
05 - Gradually add dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing to maintain tenderness.
06 - Spread dough evenly in the prepared pan. Use a spatula to create a smooth surface. Bake 18-20 minutes until edges are barely golden and center is set.
07 - Beat butter until creamy. Add powdered sugar, vanilla, and 2 tablespoons milk. Beat until smooth and fluffy; add more milk if needed for spreadable consistency. Divide and tint with pastel food coloring if desired.
08 - Spread frosting evenly over cooled cookie base. Decorate with Easter sprinkles immediately while frosting is slightly tacky.
09 - Lift bars from the pan using parchment overhang. Cut into 16 equal squares. Serve immediately or store in an airtight container.
