Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

brown sugar
rolled oats
all‑purpose flour
butter (melted)
apples (peeled, cored, chopped)
white sugar
ground cinnamon

Directions

Preheat the oven to 350 °F (175 °C). Lightly grease an 8‑inch square baking pan.
In a large bowl, combine the brown sugar, oats, flour and melted butter. Mix until the mixture becomes crumbly.
Place half of the crumb mixture into the bottom of the prepared pan, spreading it evenly.
Spread the chopped apples over that base layer.
Sprinkle the apples with the white sugar and ground cinnamon.
Top with the remaining crumb mixture, spreading it to cover the apples.
Bake in the preheated oven until the apples are bubbling and the top is crisp, golden brown and caramelized around the edges — about 40 to 45 minutes.
Remove from the oven and allow to rest a few minutes before serving.

Servings and timing

Serves: 8 
Prep time: ~20 minutes 
Cook time: ~40 minutes 
Total time: ~1 hour

Variations

Use a mix of apple varieties: choose firmer apples like Granny Smith for more texture, or sweeter apples like Fuji for a softer filling.
Add chopped nuts (such as walnuts or pecans) into the crumb topping for extra crunch.
Stir a tablespoon of lemon juice and a pinch of nutmeg into the apples for added brightness and warmth.
Swap part of the all‑purpose flour with whole‑wheat flour for a slightly nuttier flavour.
For a gluten‑free version, replace the all‑purpose flour with a gluten‑free flour blend and ensure the oats are certified gluten‑free.

Storage/Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3–4 days.
To reheat, place individual servings in a microwave for about 30–60 seconds, or reheat in a 325 °F (160 °C) oven for about 10 minutes until warmed through.
The topping will crisp up again best if reheated in the oven rather than the microwave.

FAQs

What type of apples work best in this crisp?

Firmer varieties like Granny Smith hold their shape and provide a tangy contrast, while sweeter varieties like Fuji or Gala soften more and yield a juicier filling. Choose based on your texture preferences.

Can I make this ahead of time?

Yes — prepare the dish through step 6, cover it tightly and refrigerate. When ready to bake, bring it to room temperature (if possible) and bake as directed; you may need a few extra minutes in the oven.

Can I reduce the sugar in this recipe?

Absolutely. Because apples themselves can be quite sweet, you can reduce the white sugar sprinkle or the brown sugar in the topping by up to half without major changes in texture.

What if my topping comes out soggy instead of crisp?

Make sure your crumb mixture is evenly spread and that your apples aren’t overly juicy. Avoid packing down the topping too tightly. If the filling is very moist, baking an extra 5–10 minutes may help achieve a crisp top.

Can I use frozen apples instead of fresh?

Yes, you can. If using frozen apples, thaw them first and drain off any excess liquid to prevent a watery filling. You may need to bake a bit longer for full bubbling.

Is it possible to make this dairy‑free?

Yes. Replace the butter with a dairy‑free margarine or solid coconut oil (melted) and proceed as directed. The flavour and texture will be slightly different but still very good.

Can I change the topping to only cover the top instead of both top and bottom?

Yes. The original version places half the topping below the apples and half above, but you may simplify by placing all of it on top if preferred. The difference is mainly texture and assembly.

How can I tell when the crisp is done?

The edges of the topping should be golden brown and the apple filling should be visibly bubbling around the edges. If you insert a fork into the apples and they’re tender, it’s ready.

Could I add other fruits to this crisp?

Yes. You can substitute or mix in fruits like pears, peaches or berries. Adjust baking time slightly if the fruits vary in water content or firmness.

What should I serve with this apple oat crisp?

It’s lovely on its own, but even better with a scoop of vanilla ice cream, a dollop of whipped cream or a drizzle of caramel sauce for extra indulgence.

This apple oatmeal crisp is a timeless dessert that brings together warm spices, tender fruit and a satisfying crunchy topping.
