Preheat your oven to 400ºF (200ºC) and prepare a baking sheet with parchment paper.

In a large mixing bowl, combine the flour, sugar, baking powder, and salt.

Add the frozen coconut oil and break it into the flour until pea-sized pieces form.

Fold in half of the blueberries, then add the vanilla, non-dairy milk, and lemon juice until a dough forms.

Shape the dough into a circle on the baking sheet and cut into 8 wedges.

Bake for 18-25 minutes until golden brown and a toothpick comes out clean.

Cool on a rack and drizzle with glaze made from lemon juice and confectioners' sugar.
