Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone mat.
In a medium mixing bowl, stir together Bisquick and cheese. Pour in milk and mix until a thick dough forms.
Drop dough onto the baking sheet in heaping spoonfuls. *I use a big spoon (1Tbsp) from our silverware set to scoop the biscuits. They come out to around 2-3 Tbsp of dough.
Bake for 8 to 10 minutes until the biscuits are set, tops are browning, and bottom edges are golden.
In a small bowl melt butter. Stir in garlic powder and parsley. While biscuits are still warm, brush garlic butter over the tops and let soak in. Serve warm at room temperature.
I usually get 10-12 biscuits from this recipe. It all depends on how big you make them and since we're just eyeballing it there is some yield variance.
If you don't have Bisquick available, you can substitute 2 cups flour, 1 tablespoon baking powder, and 3/4 teaspoon salt mixed together with 1/4 cup shortening cut into the flour mixture until a sand-like texture forms.
