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, approximately 2-3 minutes.
03 - Mix in the egg, vanilla extract, and almond extract until fully incorporated into the butter mixture.
04 - Gradually add dry ingredients to the wet mixture, mixing until a soft, pliable dough forms.
05 - Separate dough into two portions: approximately 2/3 for the red center and 1/3 for the green rind. Knead red coloring into the larger portion and green coloring into the smaller portion until colors are uniform.
06 - Roll the red dough into a 10-inch log, 2 inches in diameter. Roll green dough into a rectangle and wrap around the red log, pressing gently to seal.
07 - Wrap the dough log tightly 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 the 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 resemble watermelon seeds.
11 - Bake for 8-10 minutes until set but not browned. Cool on baking sheets for 2 minutes before transferring to wire racks.
