Easy Gluten Free Blueberry and Oat Crumble

Ever need to whip up a dessert in a few minutes? Maybe you’re craving something sweet but you don’t feel like cooking. Maybe you have people coming over in an hour and you need something to serve to them. OR maybe you’re bored and looking for something to do. Either way, my blueberry and oat crumble recipe is perfect!

Before we begin, I do have a few notes:

Tip #1 – Use frozen berries!

Look, you obviously can do whatever when it comes to frozen or fresh, however, frozen work JUST as well and are so much more convenient and cost-effective. This recipe uses 2 1/2 cups of blueberries! We keep frozen berries on hand CONSTANTLY in my house, so I like to use them for this recipe. That being said, fresh berries will work just as well.

Blueberries are my berry of choice when it comes to a crumble: partially because they are delicious, and partially because we had a gallon plastic bag filled with frozen blueberries. If you want to use blackberries, strawberries, or raspberries, you can!

Tip #2 – Serve with ice cream!

There’s nothing like a classic blueberry crumble and some vanilla ice cream. I didn’t make my own for this recipe, we just used store bought gluten free Breyers; however, if you want to make your own, go for it!

Tip #3 – get CERTIFIED gluten free oats

Different people have different reactions to gluten when it comes to Celiac Disease. Personally, I have had a small reaction to Bob’s Red Mill certified gf oats, so I always use Trader Joe’s.

The Ingredients –

For the blueberry layer, the ingredients are pretty simple! You probably already have all of the ingredients in your house: blueberries, sugar, lemon juice, and cornstarch.

For the oat layer on top, the ingredients are gluten free flour, butter, white and brown sugar, cinnamon, and oats!

Instructions –

The first thing to do is mix together the blueberry layer ingredients. Be gentle while mixing! You can break apart the blueberries if you use a wooden or metal spoon. Personally, I like to use a silicone spatula.

Then, gently whisk together the crumble topping ingredients. This is why this recipe is so easy! It uses very few dishes and all of the ingredients are very common.

After this, just assemble the layers. Blueberry goes on the bottom, then the oats get packed into the blueberry layer so it can fill all the empty space. I like to use my hands to make sure the crumble topping ends up in one even layer.

After this, all you need to do is bake and serve!

I hope you like this recipe as much as I do! Seriously, it is so easy and delicious! With berries in season, it’s easy to make fresh, however, it is also perfect for the winter! Frozen berries are just as great as fresh when it comes to this recipe. Happy cooking!!
