Once the peaches have cooled, start the biscuits. Preheat the oven to 450ºF.
Gather 1 cup of flour, 2 tablespoons of powdered sugar, 1 tablespoon of granulated sugar, 1 teaspoon of baking powder, and ¼ teaspoon of salt in a large mixing bowl. Mix to combine.
Add the cubed butter and use a pastry cutter to blend into a coarse meal.
Add 6 tablespoons evaporated milk and mix with a fork until a loose dough forms. Use your hands to quickly form it into a ball.
Dust your work surface with flour and turn the dough out onto the floured surface, and use your palm to press it into an oval disc. I like to lightly coat both sides with flour before I roll it out.
Use a floured rolling pin to roll the dough to ½-inch thickness. Use a round cookie cutter (I used a 2½-inch round cutter) to cut the dough into discs. Roll the excess out into another sheet and cut out the remaining biscuits until no more dough remains. The dough should yield 14 to 16 biscuits, depending on the size of your cookie cutter.
