Method
Preheat and prepare the baking dish
- Preheat oven to 375F, and pour apple cider or water into the bottom of a baking dish so it creates baking moisture. You should see a thin layer of liquid pooling in the dish.
Core and fill the apple cavities
- Core apples from the top, leaving the bottom intact, to create a cavity about 1-1/2 inches wide. The apple should still have a solid base so the filling stays inside.
- Mix brown sugar and cinnamon for the cavity filling, then place a pinch into each apple followed by a piece of butter. The cavities should look partially filled and buttery after this step.
Make the oat crumble
- In a bowl, combine rolled oats, all-purpose flour, brown sugar, cinnamon, nutmeg, and salt. Stir until evenly speckled before adding butter.
- Cut cold butter into the oat mixture until clumpy, using fingertips or a pastry cutter. The crumble should hold together in small clusters rather than becoming smooth.
Assemble and bake
- Pack crumble into and over the top of each apple, building a generous mound. The tops should be well-covered so they bake up golden.
- Bake for 35-40 minutes at 375F until the apples are tender and the crumble is golden. Look for bubbling juices at the edges and crisp, browned oat clusters.
Serve
- Serve immediately with vanilla ice cream and caramel sauce. The ice cream should melt slightly onto the warm apples.
Notes
Pro tip: keep the butter cold for a clumpier oat crumble that bakes up crisp; if it feels greasy, chill the crumble 10 minutes before topping. Store leftovers covered in the refrigerator up to 3 days; reheat in a 350F oven until warmed through (5-10 minutes). Freezing is not recommended for best oat-crisp texture. For a dairy-light swap, use plant-based butter sticks for both the crumble and cavity pieces and serve with dairy-free vanilla ice cream.
