Sliced tart apples are tossed with sugar and cinnamon and baked under a crumbly oat topping.

This baked fruit dessert combines tender, spiced apples with a crisp topping made from flour, butter and rolled oats. The dish requires minimal equipment and relies on standard pantry staples.

It takes around 25 minutes to peel and chop the fruit and mix the topping. The oven handles the rest of the work. The dessert needs to rest after baking so the hot fruit juices can thicken.

Why this works

  • Tossing the apples with a small amount of flour thickens the juices as the fruit bakes, preventing a watery filling.
  • Using cold butter in the topping creates distinct, crisp crumbs that hold their shape in the oven.
  • A brief resting period after baking lets the filling set, making it much easier to scoop into bowls.

Ingredients you'll need

Gather the apples, oats, flour, butter, sugar and spices.
  • Apples: Granny Smith or Honeycrisp hold their shape well during baking. You can mix a few different varieties for a deeper flavor.
  • Oats: Old-fashioned rolled oats give the topping a chewy texture. Avoid instant oats as they turn mushy when baked.
  • Butter: Use cold unsalted butter. If you only have salted butter, omit any extra salt you might normally add to a dessert.
  • Brown sugar: Light or dark brown sugar will work. Dark brown sugar adds a slightly stronger molasses flavor.
  • Lemon juice: A small splash of lemon juice prevents the cut apples from browning and balances the sweetness of the sugar.

How to make it

Step 1: Prepare the crumb topping

Start by mixing the flour, rolled oats, brown sugar and cinnamon in a bowl. Cut the cold butter into small cubes and work it into the dry ingredients. You can use a pastry blender or a fork to mash the butter until the mixture resembles coarse, uneven crumbs.

Step 2: Coat the apples

Peel and chop the apples into even pieces. Toss them in a large bowl with granulated sugar, a little flour, cinnamon and lemon juice. Stir the mixture until every piece of fruit is coated in the sugar and spice blend.

Step 3: Assemble and bake

Spread the seasoned apples across the bottom of a greased 8-inch baking dish. Cover the fruit completely with an even layer of the oat topping. Bake the dish until the crumbs turn golden and the filling begins to bubble.

Serve it with

Serve this dessert warm in individual bowls. A scoop of vanilla ice cream or a drizzle of heavy cream pairs well with the spiced apples.

Storage and reheating

Store leftover apple crisp in an airtight container in the refrigerator for up to 4 days. You can freeze the baked crisp for up to 3 months. Thaw it overnight in the refrigerator and reheat portions in the microwave or a 350°F (175°C) oven until warm.

FAQ

Do I have to peel the apples?

Peeling the apples yields a softer filling. You can leave the skins on if you prefer a chewier texture, but the skins will separate from the fruit as it bakes.

Can I make this ahead of time?

You can prepare the oat topping a day in advance and store it in the refrigerator. It is best to chop the apples right before baking so they do not turn brown and release too much liquid.

Why is my apple crisp watery?

A watery filling usually happens if the apples release too much juice or if the dish is cut while still piping hot. Letting the crisp cool for 20 minutes allows the flour to thicken the juices.

Ingredients

Instructions

  1. Preheat your oven to 375°F (190°C). Coat an 8-inch square baking dish with a light layer of cooking spray or butter.
  2. In a medium bowl, combine 3/4 cup (95g) of flour, the rolled oats, brown sugar and 1/2 teaspoon of cinnamon. Stir until the dry ingredients are mixed.
  3. Add the cold, diced butter to the bowl. Use a pastry blender or a fork to cut the butter into the dry mixture until it looks like coarse crumbs. Set this bowl aside.
  4. In a large bowl, combine the chopped apples, granulated sugar, 2 tablespoons (15g) of flour, 1/2 teaspoon of cinnamon and the lemon juice. Toss the apples until they are evenly coated.
  5. Transfer the apple mixture into the prepared baking dish and spread it into an even layer.
  6. Sprinkle the oat and butter topping evenly over the apples.
  7. Bake for 30 to 35 minutes. The topping will turn golden brown and the fruit juices will bubble around the edges of the dish.
  8. Remove the dish from the oven and let it cool for at least 20 minutes before serving.

Notes

  • Cut your apples into pieces that are similar in size so they cook evenly. Pieces around 3/4-inch thick work well.
  • Keep the butter cold until the moment you cut it into the flour mixture. Warm butter will melt into the dry ingredients and make a paste instead of a crumbly topping.
  • If the topping starts to brown too quickly in the oven, place a sheet of aluminum foil loosely over the baking dish.
