Ingredients

  • ¾ cup 150 g granulated sugar
  • ½ cup 113 g unsalted butter, softened
  • 1 large egg room temperature
  • Seeds from 1 vanilla bean or 2 tsp vanilla bean paste
  • 1–1½ tsp watermelon extract start with 1 tsp
  • cups 220 g all-purpose flour
  • ½ tsp baking powder
  • ¼ tsp salt
  • Optional: pink food coloring very small amount
  • Optional garnish: coarse sugar white sanding sugar, or pink crystal sugar

Instructions

  • Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
  • In a large bowl, cream butter and sugar until light and fluffy (about 2–3 minutes).
  • Beat in the egg until fully incorporated.
  • Add vanilla bean seeds and watermelon extract; mix until evenly distributed.
  • In a separate bowl, whisk flour, baking powder, and salt.
  • Gradually mix dry ingredients into wet ingredients just until combined.
  • If using food coloring, fold in a tiny amount for a soft pastel pink.
  • Scoop dough into 1½-tablespoon portions and roll gently into balls.
  • Roll tops in sanding sugar if desired.
  • Bake for 10–12 minutes, until edges are set and centers look slightly soft.
  • Cool on pan for 5 minutes, then transfer to a wire rack to cool completely.

Notes

  • Watermelon extract varies in strength; add gradually and taste the dough aroma before baking.
  • These cookies should stay pale — avoid overbaking to preserve softness and color.
  • Vanilla bean paste works beautifully if whole beans aren’t available.
  • For extra softness, chill dough for 20 minutes before baking.

Flavor Variations

  • Watermelon Creamsicle: Add ¼ tsp almond extract
  • Sparkling Watermelon: Add lemon zest (½ tsp)
