Apple crisp is my family’s signature fall dessert (and so much easier than baking apple pie!). My grandmother (Grammy) baked with Fuji and Pippin apples from her trees for decades, and I remember my mom pulling warm pans of apple crisp from the oven every fall.
These wise women taught me the three rules of apple crisp: never skimp on the crumble topping, always serve it warm, and enjoy any leftover crisp for breakfast the next day (the best with coffee!).
I’m adding my own twist to my family’s recipe. Dark brown sugar adds extra notes of caramel to the crumble topping and a splash of pure almond extract brings out the sweetness of the fresh apples.

How to Make Apple Crisp, Step by Step
Make crumble topping: Combine rolled oats, all-purpose flour, dark brown sugar, cinnamon, and salt in a medium bowl. Whisk together.


Cut in cold cubed butter with a pastry cutter until completely incorporated and large crumbs form.


Chill crumble topping for 15 minutes in the freezer (briefly freezing the topping prevents it from melting in the oven). You can also make the topping 1-2 days in advance and refrigerate until ready to use.
Make apple filling: Whisk together granulated sugar, arrowroot starch (or cornstarch), salt, and cinnamon in a large bowl.


Add apples and almond extract (or other flavoring) to the bowl. Toss with a spatula to combine.


Spoon apple filling into buttered cast iron skillet (or buttered baking dish – see note in the recipe card). Sprinkle chilled crumb topping over apple mixture.
Place skillet on preheated baking sheet (to catch any drips!) and bake for 55 to 60 minutes at 350°F, until the crumble topping is golden brown and the apple filling is bubbling. Cool crisp on a wire rack for at least 30 minutes (1 hour is even better) before serving.


We love topping warm bowls of crisp with a drizzle of salted caramel sauce or homemade butterscotch topping – so good!

Ingredients
Crumble Topping
- 1 cup (84 g) old fashioned rolled oats
- 1/2 cup (70 g) all-purpose flour
- 1/2 cup (100 g) dark brown sugar
- 1/2 tsp cinnamon
- 1/4 tsp salt
- 1/2 cup (112 g) cold unsalted butter, cubed
Apple Filling
- 2/3 cup (133 g) granulated sugar
- 3 Tbsp (24 g) arrowroot starch or cornstarch
- 1 tsp ground cinnamon
- 1/4 tsp salt
- 7 cups (840 g) peeled and diced apples
- 1/2 tsp pure almond extract
Instructions
- Place a rimmed baking sheet lined with foil in the oven and preheat to 350°F. Lightly grease a seasoned 10-inch cast iron skillet.
- Make crumble topping: Combine oats, flour, dark brown sugar, cinnamon, and salt in a medium bowl. Cut in butter with a pastry blender until well combined and large crumbs form. Chill in the freezer until ready to use.
- Make apple filling: Whisk together sugar, arrowroot starch, cinnamon, and salt in a large bowl. Add sliced apples and almond extract. Toss gently to combine. Spoon apple filling into prepared skillet and sprinkle evenly with crumble topping.
- Bake crisp: Place baking dish on preheated baking sheet and bake for 55 to 60 minutes, until golden brown and filling is bubbling. Cool crisp on a wire rack for at least 30 minutes before serving (cooling for 1 hour is best).
- Store leftover crisp tightly covered (or in an airtight container) in the refrigerator up to 2 days. Reheat in a warm oven (350°F) for 15 to 20 minutes, until heated through.
Notes
Skillet: Bake this crisp in a 9 or 10-inch skillet. For ease, you can also use a 9 or 10-inch ceramic baking dish.
Apple filling: If your apples are especially sweet and flavorful, you can reduce the granulated sugar to 1/2 cup (100 grams).
Flavor options: Pure almond extract pairs wonderfully with the apples. You can also flavor the filling with 1 teaspoon of vanilla extract, or up to 2 tablespoons of amaretto (Italian liqueur), bourbon, or dark rum.
Make ahead: Crisp topping can be made 1-2 days in advance and stored tightly covered in the refrigerator until ready to use. The apple filling can be made 1 day ahead and stored overnight in the refrigerator in a glass bowl. If you’d like to assemble the entire crisp ahead of time, I recommend using a ceramic baking dish (as cast iron may rust in the refrigerator).
Gluten free apple crisp: Make a gluten-free version of this apple crisp by substituting gluten-free oats and gluten-free flour in the topping.
I was so excited to see this as the first bake of the Bake Club because it is a favorite! Love the texture of the crisp and how easy it is to make! I made individual servings and they worked perfectly. So great for fall!
Thanks so much for sharing, Adrienne! 🙂 Love the individual servings idea too!
