Preheat your oven to 400°F (200°C). In a large mixing bowl, whisk together the flour, baking powder, and salt.

Microwave the frozen blueberries for 30-45 seconds until slightly thawed. Mash gently with a fork and set aside to cool.

In a stand mixer, beat together the vegan butter and granulated sugar until light and fluffy, about 2-3 minutes. Add the mashed blueberries and mix gently.

Gradually add the dry flour mixture to the creamy mixture, mixing on low until a cohesive dough forms. Fold in the white chocolate morsels.

Chill the dough in the freezer for about 30 minutes to enhance flavor and maintain shape while baking.

Scoop the dough into 12 equal balls and arrange on a parchment-lined baking sheet. Bake for approximately 10 minutes until the edges are lightly browned. Cool on a wire rack.
