Prep:
Preheat your oven to 350°F (175°C). Grease a 9x13 baking pan. Place the 10 cups of prepared apples evenly into the pan.
In a separate bowl, mix the 1 cup white sugar, 1 tablespoon flour, and 1 teaspoon cinnamon together. Sprinkle this mixture evenly over the apples in the pan.
Add Water: Pour the ½ cup of water evenly over the apples.
Create Crumble:
To make the topping, combine the 1 cup oats, 1 cup flour, 1 cup brown sugar, ¼ teaspoon baking powder, ¼ teaspoon baking soda, and ½ cup melted butter in a bowl. Mix until well combined.
Topping and Bake: Crumble the oat mixture evenly over the apple layer.
Bake in the preheated oven for 45 minutes, until the apples are tender and the top is golden-brown.
Notes
Recipe Notes: Aunt Becky's Apple Crisp
The Apple Choice: For the best factual results, use a firm, tart apple like Granny Smith. They hold their structure during the 45-minute bake and balance the sweetness of the crumble.
The Slicing Technique: Slice apples to a consistent 1/4-inch thickness. This ensures even cooking across all 10 cups so you don't end up with some slices crunchy and others mushy.
The Crumb Texture: When combining the butter and dry ingredients, mix only until pea-sized crumbles form. Over-mixing will create a paste rather than a "crisp" topping.
The "9x13" Pan Logic: Because this is a deep-dish crisp, do not skip the 1/2 cup of water. It creates the necessary steam to soften the massive volume of fruit before the oat topping over-browns.
Make-Ahead Best Practice: You can assemble the apple base and the dry crumble separately up to 24 hours in advance. Do not combine them until you are ready to bake to prevent the topping from becoming soggy.
