Fluffy Whole Wheat Biscuits

1 cup all-purpose flour

1 cup whole wheat flour

4 teaspoons baking powder

1 tablespoon white sugar

¾ teaspoon salt

¼ cup butter

1 cup buttermilk

Preheat oven to 450 degrees F (230 degrees C).

Combine all-purpose flour, whole wheat flour, baking powder, sugar, and salt in bowl. Cut in butter with a knife or pastry blender until mixture resembles coarse crumbs; stir in buttermilk until just moistened.

Turn dough out on a lightly floured surface; knead gently 8 to 10 times. Roll to about 3/4-inch thickness; cut with a 2 1/2-inch biscuit cutter. Place biscuits on an ungreased baking sheet.

Bake in preheated oven until biscuits are lightly browned, 10 to 12 minutes.
