Preheat oven to 350°F and lightly grease an 8×8-inch baking dish.
In a large bowl, toss the sliced apples with honey, lemon juice, and cinnamon until evenly coated.
Spread the apple mixture evenly in the prepared baking dish.
In a separate bowl, combine the oats, almond flour, coconut palm sugar, cinnamon, and salt. Pour in the melted butter and stir until the mixture forms coarse crumbs.
Sprinkle the oat mixture evenly over the apples, covering the surface completely.
Bake for 35–40 minutes, or until the topping is golden brown and the apples are tender and bubbly.
Let cool for at least 10 minutes before serving. Serve warm, optionally topped with vanilla Greek yogurt or a scoop of ice cream.
Slice apples evenly: Cutting the apples into uniform slices helps them cook at the same rate so the filling becomes tender without turning mushy.
Toss apples thoroughly: Make sure the apples are evenly coated with the honey, lemon juice, and cinnamon so the flavor is balanced throughout the crisp.
Mix topping until crumbly: The topping should resemble coarse crumbs. This helps it bake up crisp instead of dense.
Don’t pack the topping: Sprinkle the oat mixture loosely over the apples to allow air circulation and promote browning.
Rest before serving: Let the apple crisp cool for at least 10 minutes after baking so the juices thicken slightly and the topping firms up.
