Why you’ll Love this Apple Blueberry Crumble

I don’t make a ton of desserts at my house. Why? Because I have NO self-control. I will eat the whole thing. My mentality is, if I eat everything in one sitting then I won’t have anything to tempt me the next day. Haha!

But, when fall comes around. Sweets are in the air and I honestly can’t resist. Especially when it’s apple season. You can’t beat a warm fresh out of the oven apple crumble that’s topped with vanilla ice cream that starts to melt as soon as it touches the apple mixture. I mean, I’m literally salivating as I’m typing this. Today’s recipe is an Apple Blueberry Crumble topped with a crunchy cinnamon oat crumble topping that you’ll swoon over! The blueberries give a pop of tart and a vibrant color that just makes you want to dive in!

What is the Difference Between a Crumble and Crisp

If you’re anything like mean you’re probably wondering… what cobbler, crumble, crisp … what’s the difference? Well, a crumble is a dish of baked fresh fruit, with a streusel crumb topping. Similar to a crumble, a crisp is a baked fresh fruit dessert, but the streusel topping is less dense/cakey and usually includes oats. The oats will crisp up during the baking process, while the crumbles toppings stay more dense and cakey. This Apple Blueberry Crumble is kinda a mixture of the two, which is why it’s so epic – cakey and crispy goodness!

What you’ll need for this Apple Blueberry Crumble

This recipe is very straightforward – you’ll need ingredients for the apple blueberry filling and then ingredients for the oat crumble on top. Each of these components requires less than 5 ingredients and most likely you probably already have everything you’ll need on hand. Which means you can make this stat! Here’s what you’ll need:

  • Apples – I like to use Granny Smith Apples for this recipe. You could also use Gala or Honeycrisp if you’d like.
  • Blueberries – Fresh blueberries is best, but frozen will work. The frozen may make the crumble more watery, in that case you’ll need to add another tablespoon of flour to the filling mixture.
  • Cinnamon – You can’t make an apple crumble without cinnamon.
  • Flour – I use 1:1 gluten free baking flour – you’ll need it for both the filling and the crumble.
  • Honey – Adds a hint of sweet to the apple filling.
  • Lemon – Lemon juce will cut through the sweet and compliments the apples and blueberries.
  • Oats – Most crumbles don’t have oats, but I love adding a little bit for a crisp factor. Trust me, it’s amazing.
  • Brown Sugar – I rarely use brown sugar, but trust me. It’s the key to this crisp.
  • Butter – I always use unsalted butter so I can control the salt content in my desserts. Make sure it’s chilled.

Tips for Sucess

  • Fresh is Best. Always try to use fresh ingredients if you can find them.
  • Pick the Right Apple. I find that granny smith apples hold their shape the best, don’t get mushy and taste the best. I use granny smith in most if not all of my baked apple desserts. Always makes sure the peel is off, it can be tough and bitter to eat.
  • Chill the Butter. Just like you would be a pie, make sure the butter is chilled. It will lead to a nice browned crust.

How to Store Leftovers

Tightly cover the baking dish with plastic wrap. You can store leftovers on counter for up to 2 days or in the refrigerator for up to 5 days.

How to Reheat Leftovers

For a single serving, you can easily reheat this apple blueberry crumble in the microwave. Just place on a plate and warm up for 45 to 60 seconds. If you are reheating a whole crumble, I recommend heating oven to 350°F and baking for 10-15 minutes until warm.
