Ingredients
Equipment
Method
Preheat and prep
- Preheat oven to 375°F and grease a 9x13 baking dish for easy release.
- Grease the baking dish thoroughly so the crisp filling can bubble without sticking.
Make the cranberry apple filling
- Toss apples and cranberries with granulated sugar, brown sugar, cinnamon, nutmeg, orange zest, orange juice, and cornstarch until evenly coated.
- Spread the coated fruit mixture in the prepared dish in an even layer.
Make the oat crumble topping
- Combine rolled oats, all-purpose flour, packed brown sugar, cinnamon, and salt in a bowl.
- Cut cold cubed unsalted butter into the dry mixture until chunky clumps form and no large dry pockets remain.
Bake and rest
- Scatter the oat crumble evenly over the filling, covering it as completely as possible.
- Bake for 40–45 minutes at 375°F until the topping is golden and the cranberry apple filling is bubbling at the edges and thick in the center.
- Rest the crisp for 10 minutes before serving so the filling sets and thickens.
Notes
For best texture, use cold butter for the crumble and aim for chunky clumps rather than fine crumbs—this creates crisp caramelized edges. Store covered in the refrigerator up to 4 days; reheat in a 350°F oven until warmed through. Freezing is not recommended for best oat topping crunch. For a lighter option, swap half the all-purpose flour with whole-wheat flour for a fiber boost while keeping the same baking time.
