6 tablespoons/85 grams cold salted butter, cut into 1/2-inch cubes
4 medium strawberries, cut into small 1/4-inch or 1/2-inch pieces (about 2/3 cup/100 grams), or whole blueberries, raspberries or other diced stone fruit
6 tablespoons heavy cream, plus more if needed
¼ cup/30 grams unsifted confectioners’ sugar
Arrange an oven rack in the center of the oven. Heat the oven to 425 degrees. Line a sheet pan with parchment. Set aside.
Whisk the flour, granulated sugar and baking powder together in a large mixing bowl. Toss the pieces of butter into the flour mixture to coat. Using a pastry cutter or your fingers, work the butter into the flour until the mixture is mealy and small pieces of pea-size butter remain.
Add the diced strawberries and toss with a fork to combine. Make a well in the center of the mixture and add 4 tablespoons of the heavy cream and 1/4 cup water. Continue tossing with the fork until the dough is just evenly damp and shaggy, being careful not to overwork the dough too much. Add 1 to 3 teaspoons more water, as needed, if the dough is still too dry to work with.
Drop 6 mounds of dough (each a generous 1/3 cup) onto the baking sheet, leaving at least 1 1/2 inches of space between each mound and gently padding any stray bits of dough back into place as you work. Lightly brush the tops with 1 tablespoon heavy cream and bake until deep golden brown and cooked through, about 15 minutes. Remove from the oven and transfer the biscuits to a wire rack to cool for 5 minutes.
Add the confectioners’ sugar to a small bowl, and whisk in the remaining 1 tablespoon heavy cream, adding more if needed to make a thick icing that is just thin enough to drizzle. Spoon over the warm biscuits; serve warm or at room temperature.
