Questions About This Recipe

Can I use fresh fruit instead of frozen?

Fresh fruit can be used, but frozen fruit provides a consistent texture and helps keep the topping crisp during baking.

How do I make the oat topping crunchy?

Mixing melted butter with rolled oats and brown sugar creates clumps that bake into a golden, crunchy topping.

Can I substitute gluten-free oats and flour?

Yes, using certified gluten-free oats and a gluten-free flour blend allows for gluten-free preparation without compromising texture.

What can I use instead of butter for dairy-free options?

Plant-based butter substitutes or melted coconut oil work well to keep the topping rich yet dairy-free.

Is it better to let the crisp cool before serving?

Allowing it to cool slightly helps the topping set and makes it easier to serve while maintaining warm flavors.
