Gluten-Free Buttermilk Biscuits

Preheat oven to 450ºF.

Whisk corn starch, gluten-free flour, baking powder, salt, and sugar.

Cut the stick of butter into chunks and add to the dry ingredients. Using your hands, pinch butter into the dry ingredients until all the pieces of butter are flat and coated in flour. Add buttermilk and egg and stir to combine.

Once the dough has formed, dump it out onto your work surface. Pat down with your hands until dough is 1 inch thick. Use a biscuit cutter and cut out biscuits. Re-form and cut any extra dough until you can shape a biscuit by hand with the remaining dough.

Bake for 15–20 minutes. The biscuits will slightly puff up and become golden brown. Let cool slightly then serve.
