2 1/4 cups biscuit baking mix (ie: Bisquick)
2/3 cup buttermilk
1 tsp sugar
1 tbsp melted butter + additional for brushing tops
Preheat oven to 450 degrees.
Mix the baking mix, buttermilk, and sugar together in a bowl; add the melted butter and stir to make a soft dough.
On a floured flat surface, knead the dough 20 times. Roll out to a thickness of around 1/2-inch and cut out with a 2-inch biscuit cutter or a glass. Place close together on an ungreased baking sheet (I like to cover my baking sheet with parchment paper but that is a personal opinion.). Brush the tops with melted butter.
Bake at 450 degrees for 8 to 10 minutes or until lightly browned. Remove from oven and brush again with melted butter.
