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 well combined.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract and almond extract if using.
04 - Gradually add dry ingredients to the wet mixture, mixing until just combined. Avoid overmixing to maintain tender texture.
05 - Spread dough evenly in 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.
06 - 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. Divide and tint portions with pastel food coloring if desired.
07 - Spread frosting evenly over cooled cookie base. Decorate immediately with Easter sprinkles before frosting sets.
08 - Lift bars from pan using parchment overhang and cut into squares. Store in an airtight container.
