1 ½sticksSalted butter, cold, cut into the smallest cubes you can(12 tbsp)
1cupButtermilk
1Egg
1cupBlueberriesFresh or frozen
For the Glaze
1 ½cupsPowdered sugar
3tbspLemon juice
1tbspButtermilk
Instructions
Preheat the oven to 400F.
In a medium size mixing bowl, combine the self-rising flour, baking powder, baking soda, salt, and granulated sugar.
Transfer the flour mixture to the bowl of a food processor and then pour in the cubed butter. Process on a medium speed until the butter is fully incorporated and the mixture is very crumbly. If you notice large clumps building up on the side, stop the processor and use a spatula to push them down then continue processing. Watch for the color to change from white to a light yellow.
Return this mixture to the mixing bowl and add the buttermilk and egg. Stir with a spoon or spatula until well combined. The final dough will be very sticky, but should not be liquid.
Pour the blueberries into the mixing bowl and use a spatula to gently fold them in. Be gentle so that not many berries pop.
Flour a work surface (you can use either self-rising or all-purpose flour for this) and pour out the dough onto it. Dust the top of the dough with additional flour until you can pat it down without getting too sticky.
Press the dough gently into a rectangle about 1 ½ inches tall and about 9 inches wide. Make it as even as you can. Cut the rectangle into 12 even squares.
Grease a baking sheet. Take one biscuit square at a time and use your hands to gently smooth the edges into a circle and place on the baking sheet, leaving at least an inch between each biscuit.
Bake for 12 - 20 minutes until lightly browned on top. Turn the pan around in the oven after 12 minutes to ensure even browning.
Remove biscuits to a cooling rack and let them sit for 10 minutes.
While the biscuits are cooling, prepare the glaze. Combine the powdered sugar, lemon juice, and buttermilk in a small mixing bowl and use a fork or whisk to whisk until smooth. After the 10 minute cooling time, put the baking sheet under the cooling rack or put the biscuits on a plate and drizzle generously with glaze.
Serve immediately and enjoy. Cover any leftovers with foil or move to a zip top bag and store at room temperature for 2 days, or in the refrigerator for up to a week.
