Heat oven to 450°F.

Put butter in a 9×9 baking dish; place in oven to melt while making dough.

Cut together Bisquick and sour cream.

Add 7-Up to form a very very soft dough.

Sprinkle some of the extra Bisquick on your work surface and form dough into a square (roughly 9″).

Using a biscuit cutter, cut into 9 biscuits and place in the pan.

Bake for 12-14 minutes or until golden brown.

Optional: brush tops of biscuits with melted butter.
