Can I use a different store-bought apple pie?

Absolutely! Costco's apple pie is especially convenient because it's so large, but you can use another bakery apple pie. Just keep in mind that smaller pies will need less crumble topping and may require a different baking dish.

Do I leave the crust on the Costco apple pie?

Yes! Use the entire pie, including the bottom and top crust. Break everything into pieces and mix the crust with the apple filling before adding the crumble topping.

Can I use unsalted butter?

Yes. I use salted butter, but unsalted butter works just as well. Add ½ teaspoon of salt to the crumble mixture if you're using unsalted butter.

Why isn\'t my crumble topping crunchy right out of the oven?

The crumble may feel slightly soft when it's hot. As it cools, the butter and sugar firm up, helping the topping become crisp. Let the casserole rest for about 15 to 20 minutes before serving.

Can I make Costco apple pie crumble ahead of time?

You can prepare the crumble topping ahead of time and refrigerate it until you're ready to assemble the casserole. For the best texture, I recommend baking the assembled dessert shortly before serving.

What can I do with leftover crumble topping?

Freeze the extra unbaked topping in an airtight container for up to 3 months. You can sprinkle it over apples, peaches, muffins, or a small coffee cake before baking. Remember that the topping contains raw flour, so it needs to be baked before eating.
