Combine the Bisquick baking mix and sour cream in a large mixing bowl until fully incorporated. Pour in the 7-Up soda and gently mix until a sticky, soft dough forms.

Pour the melted butter into a 9×13-inch casserole dish or baking sheet to create a golden, crispy biscuit bottom.

Place the biscuits into the dish on top of the melted butter, ensuring they touch slightly for proper rising.

Bake the biscuits in the preheated oven for 12–15 minutes until the tops are golden brown. Check at the 12-minute mark to avoid over-baking.
