01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan and line with parchment paper, allowing overhang for easy removal later.
02 - In a medium bowl, whisk together the flour, baking powder, and salt until well blended.
03 - In a large bowl, beat softened butter and granulated sugar with an electric mixer until light and fluffy, approximately 2-3 minutes.
04 - Add eggs one at a time, mixing thoroughly after each addition. Blend in vanilla extract and almond extract until incorporated.
05 - Gradually mix in the dry ingredients just until combined. Avoid overmixing to maintain tender texture.
06 - Press dough evenly into the prepared pan, smoothing the surface with a spatula. Bake for 18-20 minutes until edges are lightly golden and center is set. Cool completely in the pan.
07 - Beat softened butter until creamy. Blend in powdered sugar, vanilla, and 2 tablespoons milk until smooth and fluffy. Adjust consistency with additional milk if needed. Divide and tint portions with pastel food coloring as desired.
08 - Spread frosting evenly over the completely cooled cookie base. Sprinkle with festive Easter decorations while frosting is slightly tacky.
09 - Using the parchment overhang, lift the bars from the pan. Cut into 16 squares. Store in an airtight container at room temperature up to 4 days or refrigerated up to 1 week.
