Notes
Butter: If you use unsalted butter, add in 1/4 teaspoon salt with the cinnamon. Make-ahead: Prepare the filling and the crumble topping separately. Store in the fridge up to 2 days in an airtight container and assemble while the oven preheats when you're ready to bake.Storage: Keep stored in an airtight container at room temperature up to 2 days. After that, transfer it to the fridge for a few extra days.Freeze: You can freeze this crisp either before you bake it or after once it's completely cooled. Wrap tightly in plastic wrap, or store in a freezer-friendly airtight container up to 3 months.Reheat: You can choose to thaw overnight in the fridge and bring it to room temperature 30 minutes before baking for a faster way to heat it through, or bake it directly from frozen for a little while longer. If you're just reheating a piece or two, you can microwave it at 30-second intervals until warm.
