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 evenly combined.
03 - In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, approximately 3-4 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 - Press dough evenly into the prepared pan using a spatula. Bake for 18-20 minutes until edges are barely golden and center is set. Cool completely in the pan.
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. Divide and tint with pastel food coloring if desired.
08 - Spread frosting evenly over the cooled cookie base. Immediately sprinkle with Easter-themed decorations before frosting sets.
09 - Lift the bars from the pan using the parchment overhang. Cut into 16 equal squares and serve or store in an airtight container.
