01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan and line with parchment paper, leaving an overhang for easy removal.
02 - Whisk together flour, baking powder, and salt in a medium bowl until thoroughly blended.
03 - Beat softened butter and granulated sugar in a large bowl with an electric 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 incorporated.
05 - Gradually add dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing to maintain tender texture.
06 - Transfer dough to prepared pan and spread evenly using a spatula, creating a smooth surface.
07 - Bake for 18-20 minutes until edges are barely golden and center is set. Cool completely in the pan before frosting.
08 - Beat butter until creamy. Add powdered sugar, vanilla, and 2 tablespoons milk. Beat until smooth and fluffy, adding more milk if needed for spreadable consistency.
09 - Divide frosting and tint each portion with pastel food coloring as desired.
10 - Spread frosting evenly over cooled cookie base. Decorate immediately with Easter sprinkles.
11 - Lift bars from pan using parchment overhang. Cut into 16 squares and serve or store in an airtight container.
