01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan and line with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking powder, and salt until well blended.
03 - In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, about 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. Do not overmix.
06 - Spread dough evenly in the prepared pan using a spatula to create a smooth surface. Bake for 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, adding more milk as needed for spreadable consistency.
08 - Divide frosting and tint each portion with pastel food coloring if desired, mixing until color is uniform.
09 - Spread frosting evenly over completely cooled cookie base. Decorate with Easter sprinkles while frosting is still soft.
10 - Lift bars from pan using parchment overhang and cut into 16 squares. Store in an airtight container.
