Recipe Guide

Can I use fresh apples instead of frozen?

Fresh apples work well; just peel and slice them uniformly. You may need to adjust baking time slightly for moisture.

How do I make the topping extra crunchy?

Adding chopped nuts like pecans or walnuts to the oat mixture boosts crunch and adds rich flavor.

Is it possible to prepare this in advance?

You can assemble the apple base and crumble topping separately and refrigerate them before baking the next day.

Can I substitute brown sugar for white sugar?

Yes, brown sugar enhances depth with its molasses notes, complementing the fruit and oats nicely.

How to ensure the apples don’t become mushy?

Using a mix of tart, firm apple varieties or just thawed frozen apples helps keep texture after baking.
