- 1/4 cup butter, melted
- 5 cups all-purpose buttermilk baking mix
- 1 cup lemon-lime soda (such as 7Up®)
- 1 cup sour cream
- 1/4 cup butter, softened
- Preheat oven to 425 degrees F (220 degrees C). Spread melted butter all over a 9×13-inch baking dish.
- Stir baking mix, lemon-lime soda, sour cream, and softened butter together in a bowl until dough is well-mixed; knead with your hands, adding more baking mix as necessary, until dough is smooth but still sticky.
- Roll dough into 15 equal-size balls and place dough balls in prepared baking dish, turning to coat each completely in melted butter.
- Bake in the preheated oven until biscuits are golden brown, 15 to 20 minutes. Let rest for 5 minutes before serving.
