Step 1

For the apple pie spice: Mix together the cinnamon, nutmeg, allspice and cardamom if using in a small bowl.

Step 2

For the apples: Preheat the oven to 400 degrees F.

Step 3

Place the apple halves core-side down on a flat surface. Before slicing, place chopsticks or wooden spoons on either side of them to make sure you don't cut all the way through. Slice almost all the way to the bottom of each apple half at 1/4-inch intervals, then place them on a sheet pan.

Step 4

Mix 1 tablespoon of the butter, 1 tablespoon of the brown sugar, 2 teaspoons of the apple pie spice and the orange juice in a pitcher. Drizzle over the apples, making sure they are well coated and the drizzle goes into the slits. Bake until they are just starting to get tender, about 15 minutes.

Step 5

Meanwhile, mix together the oats, almonds, salt, remaining melted butter, remaining brown sugar, orange zest and remaining apple pie spice. Sprinkle the oat mixture over the apples, making sure to get some between the slices without breaking the apples. Bake until the topping is slightly crisp and golden, another 10 minutes. Drizzle with honey and serve with ice cream.
