Instructions:
- Prepare Ingredients: Start by cutting the unsalted butter into small pats and placing them on a wax paper-lined cookie sheet. Place the sheet in the freezer for at least 10 minutes. If available, prepare a cast iron skillet with a small amount of bacon grease.
- Preheat Oven: Preheat your oven to 500°F (260°C).
- Make Sauce: In a bowl, whisk together the powdered sugar, milk, and vanilla extract until the powdered sugar is completely dissolved. Set aside.
- Combine Dry Ingredients: In a large mixing bowl, combine the all-purpose flour, baking powder, salt, and sugar.
- Cut in Butter: Add the cold unsalted butter to the dry ingredients. Use a pastry cutter or fork to cut the butter into the flour mixture until it resembles coarse crumbs, with some pea-sized pieces of butter remaining.
- Add Buttermilk: Gradually pour in the buttermilk, stirring until just combined. Add enough buttermilk to form a dough that barely sticks together.
- Knead Dough: Transfer the dough onto a well-floured surface. Press the dough out to a thickness of about 1/2 inch. Sprinkle the blueberries over the dough and knead the dough a couple of times to incorporate the berries.
- Shape Biscuits: Flatten the dough to about 1 inch thickness. Cut out biscuits using a biscuit cutter or a glass, ensuring the biscuits are touching when placed in the prepared cast iron skillet.
- Bake: Bake the biscuits in the preheated oven for 10-12 minutes, or until they are golden brown and the blueberries have burst.
- Brush with Butter: After about 6-8 minutes of baking, remove the skillet from the oven and brush the biscuits generously with melted salted butter. Return the skillet to the oven and continue baking until done.
- Glaze: Once the biscuits are baked, let them cool in the skillet for about 10 minutes. Drizzle the prepared sugar glaze over the warm biscuits.
- Serve: Serve the Sweet Blueberry Biscuits warm and enjoy the delightful combination of juicy blueberries, tender biscuits, and sweet glaze.
These Sweet Blueberry Biscuits are perfect for breakfast, brunch, or as a sweet treat any time of day. Enjoy the burst of blueberry flavor in every bite, and savor the comforting warmth of these homemade biscuits.
