1⁄4 cup granulated sugar
2 tsps baking powder
1⁄2 tsp baking soda
1⁄2 tsp kosher salt
3 cups all-purpose flour, plus more for surface
1⁄2 cup chilled unsalted butter, cut into pieces
1 large egg, beaten
11⁄4 cups heavy cream
11⁄2 cup shredded sharp cheddar cheese, divided
1 cup diced apple, about 2 apples
Preheat oven to 375°F and line a baking sheet with parchment paper.
Whisk sugar, baking powder, baking soda, salt, and flour in a large bowl until combined and set aside. Add butter and toss to coat. Using your fingers, work butter into flour by flattening each piece between your thumb and pointer finger.
Make a well in the center; add eggs and cream to the center and mix, incorporating dry ingredients a little at a time, until shaggy dough forms. Add 1 cup of the cheddar and the apples.
Turn the dough out onto a floured surface and fold over itself 3-4 times to incorporate remaining flour. The dough will seem dry. Roll out the dough until 1” thick. Making sure to keep it as square as possible.
Cut into 12 squares but making 2 cuts in one direction and 3 cuts in the perpendicular direction. Transfer to baking sheet and brush dough with cream and sprinkle with the remaining cheese.
Bake until golden brown, 10-15 minutes.
Enhance by serving with butter and apple butter.
