Add the Bisquick, butter, and shredded cheese to a large bowl. Use a pastry cutter to work in the butter and cheese until the mixture is crumbly like coarse bread crumbs. Refrigerate for 15 minutes (this will make them flakier).
Preheat your oven to 400°F and grease a large baking sheet.
Gently stir the milk into the Bisquick mixture until JUST combined. Be careful not to overmix, otherwise the biscuits will be dense; there should be plenty of lumps.
Dust your work surface with Bisquick. Using a rolling pin, flatten the dough into a ½-inch thick rectangle. Cut into shapes using a cookie cutter or knife and place them on the greased baking sheet.
Bake for 10-12 minutes until the tops are lightly brown. Enjoy!
