01 - Whisk together flour, baking powder, and salt in a medium bowl until evenly combined.
02 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, about 2-3 minutes.
03 - Mix in egg, vanilla extract, and almond extract until fully incorporated into the butter mixture.
04 - Gradually add dry ingredients to wet mixture, mixing until a soft dough forms. Avoid overmixing.
05 - Split dough into two portions: larger portion (about 2/3) for red, smaller portion (about 1/3) for green. Knead red coloring into larger portion and green coloring into smaller portion until colors are evenly distributed.
06 - Roll red dough into a 10-inch long, 2-inch diameter log. Roll green dough into a rectangle and wrap it around the red log, pressing gently to seal the edges.
07 - Wrap the combined dough log in plastic wrap and refrigerate for at least 1 hour until firm enough to slice cleanly.
08 - Preheat oven to 350°F and line baking sheets with parchment paper.
09 - Cut chilled dough into 1/4-inch thick rounds. Slice each round in half to create watermelon wedge shapes.
10 - Press mini chocolate chips into the red portion of each cookie slice to mimic watermelon seeds.
11 - Bake for 8-10 minutes until cookies are set but not browned. Cool on baking sheet for 2 minutes before transferring to wire rack to cool completely.
