3 cups all-purpose flour, 1 tbsp baking powder, ½ tsp baking soda, 1 tsp salt, 2 tbsp granulated sugar
Cube the 2 sticks unsalted butter and cut it into the flour mixture using a pastry cutter or fingers until you have pea-sized pieces.
2 sticks unsalted butter
Pour in 1¼ cups cold buttermilk and mix gently until the dough is shaggy and barely combined.
1¼ cups cold buttermilk
Turn dough onto a floured surface and pat it into a 1-inch thick rectangle. Place a few paper-thin slices of the 3 tbsp unsalted butter over the top of the dough (about ⅓ of the slices).
3 tbsp unsalted butter
Fold the rectangle into thirds (like a letter). Rotate 90°, roll it out again to 1-inch thick, and repeat the process two more times, layering butter each time before folding. Do 3 folds total, distributing the thin butter slices evenly.
Roll the dough to ¾-inch thick, cut with a sharp 2½-inch biscuit cutter (press straight down, no twisting), and place biscuits close together on a parchment-lined sheet.
Freeze biscuits for 10 minutes before baking.
Bake at 425°F for 15–18 minutes until golden and tall. Brush tops with melted butter if desired.
Whisk together the chopped 1/2 cup strawberries, 3/4 cup powdered sugar, 1 tsp salt, and1 tsp vanilla extract until silky and smooth.
1/2 cup strawberries, 3/4 cup powdered sugar, 1 tsp salt, 1 tsp vanilla extract
Let the biscuits cool for at least 30 minutes before glazing. Pour an equal amount of the glaze over the cooled biscuits, letting it drip down the sides to fully envelope.
