01 - Preheat oven to 350°F. Grease and line a 9x13 inch baking pan 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 softened butter and granulated sugar 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 if using.
05 - Gradually incorporate dry ingredients into the wet mixture, mixing until just combined. Avoid overmixing to maintain tenderness.
06 - Press dough evenly into 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. Cool completely in the pan.
07 - Beat softened butter until creamy. Add powdered sugar, vanilla, and 2 tablespoons milk, beating until smooth and fluffy. Adjust consistency with additional milk if needed. Divide and tint portions with pastel food coloring if desired.
08 - Spread frosting evenly over the cooled cookie base. Immediately sprinkle with festive Easter sprinkles before frosting sets.
09 - Lift bars from the pan using parchment overhang. Cut into 16 equal squares and serve or store in an airtight container.
