Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the almond flour, baking powder, and salt.
2 cup almond flour, 2 tsp baking powder
Cut in the cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
0.5 tsp salt
In a separate bowl, whisk together the almond milk and apple cider vinegar. Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.
0.25 cup unsalted butter
Drop rounded tablespoons of dough onto the prepared baking sheet.
Bake for 18-20 minutes, or until golden brown.
Let the biscuits cool on the baking sheet for a few minutes before serving.
Notes
For a dairy-free option, use coconut oil instead of butter. Biscuits are best served warm.
