This simple crumble is full of flavor but takes just a few minutes to prepare. For the best texture, be sure to chop the apples into pieces that are even in size

3. Combine the topping ingredients in a bowl.
4. Spread the topping over the apples.
5. Place the dish in a preheated oven and bake until the oat topping is crispy and golden.

Storage Suggestions

The great thing about this sweet treat is that it stores well so you can easily keep it around for nearly a week to have as a snack, dessert, or even breakfast. To keep the crisp topping crunchy, reheat in the oven at 325° Fahrenheit for about 10-15 minutes. You can also microwave it for 20-30 seconds.

Once it cools to room temperature store this crumble in the fridge in an airtight container (or cover the dish with aluminum foil) and refrigerate for up to 5 days.

Freeze the crumble for up to 3 months in a freezer-safe container.

Kitchen Tips For Success

• While I used gala apples for the apple filling for this recipe, you can change up the flavor profile using any kind of apples that you prefer. Use pink lady, golden delicious, honey crisp, or Granny Smith apples. You can also use Braeburn apples if you want an apple that maintains its shape well when cooked. 
• Avoid syrups with sugars — I highly recommend using real maple syrup. 
• Use old-fashioned oats for the best texture.

Cobbler, Crumble, and Crisp: What Sets Them Apart?

• Cobbler: Like my Peach Cobber has a biscuit-like topping dropped over fruit, creating a “cobbled” look.
• Crumble: Streusel topping of flour, butter, and sugar that is crumbled over the fruit. May or may not include oats or nuts.
• Crisp: Similar to a crumble but includes oats or nuts for extra crunch.

What do I serve with apple oatmeal crumble?

Apple crumble is an incredibly easy dessert that can be thrown together in minutes. Serve it warm with a scoop of your favorite ice cream, caramel sauce, or cinnamon whipped cream on top!

With its simple ingredients, you can easily serve this as a breakfast dish as well. Instead of ice cream try adding your favorite yogurt as a topping.

Apple oatmeal crumble is the dessert you didn’t know you needed! Bursting with tender apples and a crispy, buttery oatmeal topping, it’s the ultimate fall treat that you’ll find yourself craving all season long.
