Preheat the oven to 350°F. Line baking sheets with parchment paper.

In a medium bowl, whisk together the flour, baking powder, and salt.

In a large bowl, beat butter and 1 1/4 cups sugar until light and fluffy (about 3 minutes). Add egg, egg yolk, and vanilla, then slowly beat in the flour mixture.

Remove just over half of the dough (about 435 grams) to a separate bowl. To the remaining dough, add crushed freeze-dried strawberries and mix on low speed until combined.

Portion plain dough into 1-tablespoon balls and shape into 5-inch logs. Repeat with strawberry dough.

Press one plain log and one strawberry log together, then gently roll into a flat spiral. Roll the spiral into a ball, keeping the spiral on top. Repeat with remaining dough.

Roll each dough ball in the remaining 1/4 cup sugar to coat evenly. Place on prepared baking sheets, spacing 2 inches apart, and flatten slightly.

Bake for 11 to 12 minutes until set and edges are lightly browned. Cool for 5 minutes before transferring to a wire rack to cool completely.
