01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan and line with parchment paper, leaving overhang for easy removal.
02 - Whisk together flour, baking powder, and salt in a medium bowl until evenly blended.
03 - Beat butter and sugar in a large bowl with electric mixer until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating thoroughly after each addition. Mix in vanilla extract and almond extract until incorporated.
05 - Gradually add dry ingredients to wet mixture, mixing just until combined. Avoid overmixing to maintain tender texture.
06 - Press dough evenly into prepared pan, smoothing surface with spatula. Bake for 18-20 minutes until edges are lightly golden and center is set.
07 - Beat butter until creamy. Blend in powdered sugar, vanilla, and 2 tablespoons milk until smooth and fluffy. Add remaining milk if needed for spreadable consistency.
08 - Divide frosting and tint with pastel food coloring if desired. Spread evenly over completely cooled cookie base.
09 - Sprinkle with festive Easter decorations. Lift bars from pan using parchment overhang and cut into squares.
