Preheat & Prep:
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Make the Dough:
In a large bowl, beat the butter and sugar until light and fluffy. Add the egg and vanilla extract, mixing until combined. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms.

Roll & Cut:
Lightly flour a clean surface and roll out the dough to about 1/4-inch thickness. Use Easter-themed cookie cutters (bunnies, eggs, chicks) to cut out shapes. Transfer cookies to the baking sheet.

Bake:
Bake for 8-10 minutes or until the edges are lightly golden. Let cookies cool on a wire rack before decorating.

Make the Icing:
In a bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Divide icing into separate bowls and mix with different food coloring shades.

Decorate:
Use a spoon or piping bag to decorate the cookies with the icing. Add sprinkles for a festive touch. Allow the icing to set before serving.

Serve & Enjoy:
Store in an airtight container for up to 5 days.
