What’s the Difference Between a Crumble and a Crisp?

Both a crumble and crisp include a fruit base with a streusel-style topping. Generally, a crumble has a flour and butter topping, and a crisp topping includes oats.

Many people use these terms interchangeably when talking about this type of dessert.

  • Cornstarch
  • Sugar – both white and brown

  • All-purpose flour – see FAQ below on making this gluten-free.

How to Make Apple and Blueberry Crumble

*I’ll walk you through it here with some photos and tips, and you’ll also find a printable recipe card at the bottom of the post with exact measurements, etc. You can also click “jump to recipe” to skip down.

Butter a 9×13 baking dish and preheat the oven to 350˚F (180˚C).

Then you’re going to tackle the apples. You can peel them or leave them unpeeled – chef’s choice. I prefer to peel them, but you do you.

Slice and chop the apples into ~1/2-inch pieces. Do your best to make the sizes uniform so that everything bakes evenly.

To make fast work of this, I love using my apple peeler and corer. It also helps when canning applesauce, canning apple pie filling, dehydrating apples, making steamed apples with cinnamon, and canning apple butter.

Grab a mixing bowl and toss the apples with the blueberries, lemon juice, cornstarch, and just a bit of sugar. Pro tip: to save on dishes, IF you have a deep baking dish, go ahead and mix all this directly in the dish.

If you didn’t mix the fruit in the baking dish, go ahead and add it now. Scrape any juices and sugar over the fruit that has accumulated in the bottom of the mixing bowl.

In a microwave-safe mixing bowl, warm butter until it is about 50% melted and 50% softened. You don’t want it be all liquid, but you also don’t want it fully solid. See the photo below if you need a visual representation of this.

Add flour, white and brown sugars, cinnamon, and vanilla extract. Stir with a fork to distribute the butter. The mixture should have some clumps and if you grab a pinch of it and make a ball, it should hold together. It should feel like buttery sand. Pro tip: don’t eat actual sand.

Top the fruit with the crumble mixture. Some clumps are ok, but break apart any overly large clumps.

Bake it uncovered for 45-50 minutes or until the crumble topping is lightly browned and the fruit is bubbling. For best results and to prevent lava mouth, go ahead and let it cool for 15(ish) minutes before serving.

What to Serve With Blueberry Apple Crisp

This crisp is absolutely delicious topped with vanilla ice cream, homemade whipped cream, or even some Greek yogurt. We also love it on its own without anything else after baking.

HOW TO STORE AND REHEAT

Storing Leftovers: Allow the crisp to cool and store covered leftovers at room temperature for 2-3 days or in the fridge for 4-5 days.

Reheating Leftovers: Blueberry apple crumble can be enjoyed cold, at room temperature, or heated. To reheat, cover and microwave individual servings for 35 seconds.

Freezing Crumble: You can assemble the crumble and freeze it unbaked for 3-4 months, as long as you cover it tightly to prevent freezer burn. I would cover it with plastic wrap and then foil.

To freeze leftover baked crumble, transfer it to freezer-safe containers and freeze for 3-4 months.

Frequently Asked Questions

Can I Use Frozen Blueberries?

Yes, frozen blueberries would work great in this crisp!

You have two options for using frozen blueberries: 1) rinse the frozen blueberries in a strainer/mesh sieve until thawed, and then add them to the fruit mixture or 2) add them completely frozen and increase the cornstarch by 1 tbsp.

You can also check out our tutorial on freezing blueberries to create your own freezer stash.

Can I Use Frozen Apples?

You sure can! Using frozen fruit makes assembling this crumble a breeze.

Unlike thawing the blueberries, I do not recommend thawing the apples before adding them to the fruit mixture. There is too much chance that they will oxidize (brown) during the thawing process.

Instead, add them directly from the freezer and increase the cornstarch by 1.5 tsp.

Can This Recipe Be Gluten-Free?

Absolutely! You can either sub in your favorite cup-for-cup gluten-free flour or use all old-fashioned oats.

Gluten-free flour tends to be a bit “thirsty” with liquids/fats which can result in a dry topping texture. Start with the 8 tbsp of butter listed in the recipe, but expect to add 1-2 tbsp more to achieve the same texture.

Check out our gluten-free blackberry crisp recipe and gluten-free strawberry rhubarb crisp for more information.

Can This Recipe Be Dairy-Free?

You bet! Sub in your favorite dairy-free butter for the butter listed in the recipe card.

To make it more economical, you could also use half plant-based butter, and half melted coconut oil.

Pro Tips/Recipe Notes

  • Spoon the flour into the measuring cup instead of the ol’ “scoop and dump” method. That will pack the cup too full and will produce a dry crumble topping.
  • Sustainability tip: to save money and resources, use the leftover butter wrapper to grease the baking dish.
  • If you leave the peel on the apples, consider selecting apples with thinner skin such as Fuji or Braeburn. Granny Smith apple peels can be somewhat thick when baked.
  • If your apples are extra sweet, you can leave out the 1/4 cup of sugar altogether. If they are extra tart, increase the sugar to 1/3 cup.
