Recipe Help & FAQs

Can I use fresh fruit instead of frozen?

Yes, fresh fruit can be used; adjust sugar and baking time as fresh fruit releases more juice.

How do I make the topping extra crunchy?

Add chopped nuts like walnuts or pecans to the oat topping for additional texture and crunch.

Is it possible to make a dairy-free version?

Use melted coconut oil or plant-based butter substitutes instead of unsalted butter in the topping.

What type of oats works best?

Old-fashioned rolled oats provide the best texture and absorb moisture well in the topping.

Can I prepare this ahead of time?

Yes, assemble the crisp and refrigerate before baking; bake fresh when ready to serve.
