01 - Whisk together flour, baking powder, and salt in a medium bowl until well combined.
02 - Beat softened butter and granulated sugar in a large bowl until light and fluffy. Add egg, vanilla extract, and almond extract, mixing until fully incorporated.
03 - Gradually add dry ingredients to wet mixture, mixing until soft dough forms and no dry streaks remain.
04 - Divide dough into two portions: larger portion (about 2/3) and smaller portion (about 1/3). Tint larger portion with red food coloring, kneading until color is evenly distributed. Tint smaller portion with green food coloring.
05 - Roll red dough into a 10-inch long, 2-inch diameter log. Roll green dough into a rectangle large enough to wrap around the log. Carefully wrap green dough around red log, pressing gently to adhere.
06 - Wrap combined dough log in plastic wrap and refrigerate for at least 1 hour or until firm enough to slice cleanly.
07 - Preheat oven to 350°F. Line baking sheets with parchment paper.
08 - Slice chilled dough into 1/4-inch thick rounds. Cut each round in half to form watermelon slices.
09 - Place slices on prepared baking sheets. Press mini chocolate chips into red portion of each slice to mimic watermelon seeds.
10 - Bake for 8-10 minutes until cookies are set but not browned. Cool on baking sheet for 2-3 minutes before transferring to wire rack to cool completely.
