Recipe Guide

What fruits work best in this dish?

Mixed berries, peaches, and apples are great choices, but any frozen fruit combination works well.

Can I add nuts to the topping?

Yes, adding chopped walnuts or pecans gives a pleasant crunch to the oat topping.

How can I make this dish dairy-free?

Substitute the butter with melted coconut oil or a vegan butter alternative.

Is it better to use flour or cornstarch for the filling?

Both work as thickeners; flour adds heartiness while cornstarch creates a clearer filling.
