Creating Apple Bubble-Up Casserole is an enjoyable process. Just follow these straightforward steps:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C).
2. Prep the Biscuit Dough: Open the cans of refrigerated biscuit dough. Cut each biscuit into quarters or smaller pieces for easier mixing and layering.
3. Prepare the Apples: In a large mixing bowl, combine the chopped apples, 1/2 cup of granulated sugar, 1 teaspoon of cinnamon, and 1/2 teaspoon of nutmeg. Toss until the apples are well coated.
4. Layer the Dough: Add the chopped biscuit pieces to the apple mixture. Gently fold them together until the biscuits are thoroughly mixed with the apple mixture.
5. Pour the Cider: In a separate bowl, mix the apple cider or juice with the remaining 1/2 cup of sugar and vanilla extract. Pour this mixture over the apples and biscuit dough, ensuring an even distribution.
6. Transfer to a Baking Dish: Grease a large baking dish (9×13-inch works well). Pour the apple and biscuit mixture into the dish, spreading it out evenly.
7. Melt the Butter: In a small bowl, melt the unsalted butter in the microwave or on the stove. Once melted, pour it evenly over the top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the biscuits are golden brown and the apples are bubbling.
9. Cool Slightly: Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. It will be extremely hot, so this cooling time is essential for safer serving.
10. Serve Warm: If desired, dust the top with powdered sugar for an extra touch of sweetness and presentation.
