Simple and quick: With just a few pantry staples and minimal prep, you can have a warm, bubbling dessert on the table in under an hour and a half.

Uses seasonal apples: This recipe highlights fresh fall apples—firm varieties hold up well in baking and give the crisp a great texture and flavor contrast with the topping.

Customizable sweetness: The recipe works with regular white and brown sugar or reduced-calorie sugar blends if you prefer to cut calories while keeping the sweet flavor.

Versatile serving options: Serve it warm with vanilla ice cream, dollop with whipped cream, or enjoy a scoop over pancakes or waffles for a cozy breakfast twist.

Easy Apple Crisp Ingredients Notes

Apples – The recipe uses Granny Smith apples for their firmness and tartness, which balance the sweet topping. Other good baking apples include Honeycrisp, Braeburn, or Pink Lady.

Oats – Rolled oats give the topping a hearty texture. If you use quick oats, you may want to reduce the butter slightly so the topping doesn’t become too soft.

Sugars – This crisp calls for both white and light brown sugar. You can substitute reduced-calorie blends that mix a natural sweetener with sugar to lower calories, if desired.

Spice – Ground cinnamon is a classic pairing with apples. Feel free to add a pinch of nutmeg, ginger, or pumpkin spice for extra warmth.

See the ingredient list below for exact measurements.

Ingredients

For the apples

  • 6 Granny Smith apples, peeled, cored, and thickly sliced (about 6–8 slices per apple)
  • 1 cup white sugar (or ½ cup reduced-calorie sugar blend)
  • 1 tablespoon all-purpose flour
  • 1 teaspoon ground cinnamon
  • ½ teaspoon kosher salt

For the topping

  • 2 cups rolled oats
  • 2 cups all-purpose flour
  • 2 cups light brown sugar (or 1 cup reduced-calorie brown sugar blend)
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon kosher salt
  • 2 sticks butter, melted (about 1 cup)

How To Make Easy Apple Crisp

  1. Preheat: Set your oven to 350°F (175°C).
  2. Prep the apples: Peel, core, and slice the apples into thick slices. Place them in a 9×13-inch baking dish.
  3. Toss with sugar and spice: Combine the white sugar, 1 tablespoon flour, cinnamon, and ½ teaspoon salt. Pour this mixture over the apple slices and toss until evenly coated.
  4. Make the topping: In a bowl mix the rolled oats, all-purpose flour, brown sugar, baking powder, baking soda, and ½ teaspoon salt. Stir in the melted butter until the mixture is evenly moistened and crumbly.
  5. Assemble: Spread the oat topping evenly over the apples, covering them completely.
  6. Bake: Bake for 45–60 minutes, until the apples are tender and the topping is golden brown and bubbling.
  7. Rest and serve: Let the crisp cool for about 15 minutes before serving. Top with vanilla ice cream, whipped cream, or a drizzle of caramel if desired.

Variations, Substitutions, & Cooking Tips

Add nuts: Fold in toasted pecans or walnuts to the topping for extra crunch and a toasty flavor.

Try different spices: Along with or instead of cinnamon, try nutmeg, ginger, or a pinch of cloves for depth.

Mix fruit: Add a handful of fresh or frozen berries with the apples, or swap some apples for pears for a milder sweetness.

Adjust texture: For a crumblier topping reduce the butter a bit; for a chewier topping use slightly more butter or a little honey or maple syrup mixed in.

Serving ideas: Warm apple crisp is excellent with a scoop of vanilla ice cream, a drizzle of caramel sauce, or a spoonful of crème fraîche.

Storage & Reheating

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. The topping may soften over time.

Freezing: You can freeze portions in a freezer-safe container for up to one month; note the topping texture may change slightly when thawed.

Reheating: Reheat in a 325°F oven for about 10 minutes or until heated through to restore some crispness. For single servings, microwave in 30–45 second bursts until warm.

Nutrition & Notes

This recipe can be made with regular sugar or reduced-calorie sugar blends to lower calories. Nutrition values will vary depending on the ingredients and portion size. If you prefer a lighter version, reduce the brown sugar or swap half the butter for applesauce, keeping in mind the topping texture will change.
