Microwave frozen blueberries for 30 to 45 seconds until softened, then gently mash and let cool.

In a stand mixer, combine softened vegan butter and granulated sugar. Beat for 2-3 minutes until light and fluffy. Mix in cooled mashed blueberries.

Gradually add dry mixture to the wet mixture, mixing until a soft dough forms. Avoid overmixing.

Fold in white chocolate morsels evenly into the dough, then freeze for 30 minutes.
