Warm Cinnamon Apple Crisp with Golden Oat Streusel
Tender spiced Honeycrisp and Granny Smith apples baked under a buttery, brown sugar and rolled oat crumble topping, served warm with vanilla bean ice cream.
Why This Recipe Works
- Apple Variety Blend: Mixing tart Granny Smith with sweet crisp Honeycrisp balances flavor and texture so the filling doesn’t turn to mush.
- Cornstarch Binding: A touch of cornstarch creates a silky, spiced syrup around the tender baked apples.
- Cold Butter in Streusel: Cutting cold butter into the oats and flour guarantees distinct, crispy crumb clusters rather than a greasy paste.

Ingredients (US Customary)
-
6 medium apples (blend of Granny Smith and Honeycrisp), peeled, cored, and sliced 1/4-inch thick
-
2 tablespoons pure maple syrup or granulated sugar
-
1 tablespoon fresh lemon juice
-
1 tablespoon cornstarch
-
1.5 teaspoons ground cinnamon
-
0.25 teaspoon ground nutmeg
-
1 cup old-fashioned rolled oats
-
0.5 cup all-purpose flour
-
0.5 cup packed light brown sugar
-
6 tablespoons cold unsalted butter, cubed
Step-by-Step Instructions
-
1Prep Oven & Filling
Preheat oven to 350°F (175°C). Grease an 8×8-inch or 9-inch round baking dish with butter. In a large bowl, toss apple slices with lemon juice, maple syrup, cornstarch, 1 teaspoon of cinnamon, and nutmeg until well coated. Spread evenly into the baking dish.
-
2Make Streusel Topping
In a separate bowl, stir together the rolled oats, flour, brown sugar, remaining 1/2 teaspoon cinnamon, and a pinch of salt. Add cold cubed butter. Use a pastry cutter or your fingertips to work the butter in until coarse, pea-sized crumbs form.
-
3Bake to Golden Perfection
Scatter the oat topping evenly over the apples. Bake for 40 to 45 minutes until the streusel is deep golden-brown and the apple juices are bubbling warmly around the edges.
-
4Cool & Serve
Let cool for 10 minutes so the juices settle slightly. Spoon into dessert bowls and top with generous scoops of vanilla bean ice cream.
Kitchen Notes & Chef Tips
Nut Variation: Add 1/3 cup of chopped pecans or walnuts to the oat topping for extra autumnal crunch.
Reheating: Crisp in a 350°F oven for 8 minutes rather than microwaving to preserve the crunchy streusel texture.
