Tart cranberries and Honeycrisp apples baked under a buttery brown sugar oat topping. No pie crust and no mixer, and you can assemble it ahead for Thanksgiving.
In a large bowl, mix the flour, oats, brown sugar, cinnamon, and salt. Add the cold cubed butter and vanilla extract and work it in with a pastry cutter or clean hands until the mixture is crumbly and looks like small peas. Place the bowl in the fridge while you make the filling.
2/3 cup all-purpose flour, 3/4 cup old-fashioned oats, 2/3 cup brown sugar, 1/2 tsp cinnamon, 1/2 tsp salt, 1/2 cup butter, 1 tsp vanilla extract
Peel and chop the apples. In a second large bowl, toss them with the cranberries, brown sugar, cornstarch, cinnamon, nutmeg, and vanilla extract. Spread into a 9-inch pie plate or an 8x8-inch square pan.
3 large Honeycrisp apples, 1 1/2 cups cranberries, 1/2 cup brown sugar, 1 tsp cinnamon, 1/4 tsp nutmeg, 1 tsp vanilla extract, 3 tbsp cornstarch
Sprinkle the chilled topping evenly over the fruit. Set the dish on a baking sheet to catch any drips and bake uncovered for 55 minutes, until the topping is golden. If the top darkens too fast, tent it loosely with foil.
Let the cranberry apple crisp rest for 5 to 10 minutes to set before serving with vanilla ice cream or whipped cream.
Notes
Don't skip the cornstarch. It's what keeps the filling from going watery.
Apples: For a more balanced filling, use half Honeycrisp and half Granny Smith.
Make ahead: Assemble up to 3 days ahead and refrigerate, or freeze unbaked and bake from frozen, adding a few extra minutes.
