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 well combined.
03 - In a large bowl, beat butter and sugar with a mixer until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract and almond extract.
04 - Gradually add dry ingredients to the wet mixture, mixing until just combined. Do not overmix.
05 - Spread dough evenly in the prepared pan using a spatula to create a smooth surface. Bake 18-20 minutes, or until edges are barely golden and center is set. Let 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 frosting and tint each portion with pastel food coloring if desired.
07 - Spread frosting evenly over cooled cookie base. Decorate with Easter sprinkles. Lift bars from the pan using parchment overhang and cut into squares.
