In a medium size bowl mix sour cream and Bisquick together.
Slowly pour in Sprite, mix until it looks like dough.
Lightly flour a surface and knead the dough for 1 minute or 2. * NOTE* This dough is extremely sticky so you might need to use some additional flour.
Cut the dough into 4 biscuits and place on cookie sheet lined with parchment paper. Brush melted butter on the top of each. Bake till golden brown - about 15 minutes.
Enjoy
