Pro Tips
Butter: Use a cheese grater to cut butter into small pieces. Best if butter is very cold. Then using a fork or a pastry cutter mix the butter into the dry ingredients until mixture is a crumb texture.Buttermilk: Recipe calls for Buttermilk. Make your own buttermilk by combining 1 cup milk with 1 Tablespoon cider vinegar and allow mixture to sit for 10 minutes.
Serve
Enjoy hot blueberry biscuits right out of the oven or serve with glaze drizzle for an extra sweetness.
Storage & Make Ahead
Store: Keep biscuits in an airtight container at room temperature for up to two to three days. For longer freshness, refrigerate for up to a week.
Freeze: Wrap each biscuit individually in plastic wrap, then store in a freezer-safe bag or container for up to three months.
Reheat: Warm biscuits in a 350°F oven for 5-7 minutes for the best texture. A quick 15-20 seconds in the microwave works too, though they’ll be softer.
Make Ahead: Prepare the dough in advance, wrap it tightly in plastic wrap, and refrigerate for up to 24 hours before baking. You can also freeze unbaked biscuits and bake straight from frozen, adding a few extra minutes to the bake time.
