Not one I’ve tried yet, but seems like it would work…
2 c Bisquick mix
1/2 c sour cream
1/2 c 7up
1/4 c melted butter
Preheat oven to 450º
Cut sour cream into your Bisquick mix, then add 7up – it will make a soft dough. Now sprinkle your counter with a little Bisquick mix then add dough and pat it out.
Melt butter and pour it into a 9″ square baking pan. Cut your biscuits up and arrange them in pan on top of melted butter.
Bake 12-15 minutes or until golden brown.
