Notes
To Make Biscuits: Yields 8 2 1/2 inch biscuits
1 1⁄2 cups homemade bisquick mix
1⁄2 cup milk
2 tablespoons butter, melted
Preheat oven to 400 degrees and spray cookie sheet with non-stick cooking spray or line with parchment paper to prevent sticking.
Combine ingredients in a medium bowl until soft dough forms, do not over mix.
Turn onto a lightly floured surface, roll dough out with a rolling pin to about 1⁄2 inch thick and cut with a 2 1/2 inch wide round cookie cutter (or a different shape with similar diameter).
Alternately, drop into 8 equal size biscuits using a spoon, pat down a little so they aren't too tall.
Bake for 7-9 minutes until lightly browned.
Remove from oven and baste with melted butter. Serve!
