Step 1

Preheat the oven to 425 degrees.  Add butter to a 9x13-inch baking dish and place in the oven for 5-7 minutes to melt the butter. Keep an eye on the butter, as you do not want it to burn. Remove the pan from the oven.

Step 2

In a large bowl, mix together 4 cups Bisquick, 7up, and sour cream.  The dough will be quite sticky. Sprinkle 1/4 cup Bisquick over a small work area. Spoon dough over top.  Sprinkle 1/4 cup Bisquick over the dough.  Dust hands with Bisquick.

Step 3

Work the dough by patting and folding. Repeat until the dough is workable. Pat the dough out to 1 inch thick. Dip biscuit cutter in Bisquick. Cut the biscuits and place them in the baking dish with the melted butter. Rework the dough just enough to pat it out to cut any remaining biscuits.

Step 4

Bake for 12-14 minutes or until golden brown and cooked through.
