These apple crumb bars make the perfect breakfast, incredibly delicious dessert or even an indulgent snack. Serve them warm for a comforting treat, cold when on the go or with a generous scoop of vanilla ice cream on top.

There’s something about this season that makes us all crave apple treats. However, making an apple pie from scratch can be a painful process. There’s a lot of refrigeration involved, a rolling pin and a good share of craftiness (hello, pie crust toppings that seem incredibly difficult to replicate). 

These apple crumb bars pack all the apple flavors we crave + all the deliciousness of a homemade apple pie but in a super easy to make form. 

You don’t need a lot of fancy ingredients and definitely not a ton of technique the process is as simple as it can get and only takes around 15 minutes of active time. 

Now let’s dive deep into this super easy recipe.

How to make delicious apple crumble bars?

For me, the secret to delicious apple pie bars is a great crust and topping and a super flavorful filling. 

For the crust, I like to go with a combination of: 

  • Oats
  • Flour
  • Butter
  • Sugar
  • Spices

Some people prefer to keep their crust neutral but I prefer to infuse it with flavor so every part of the crumble bar is delicious (and not just the filling!). 

Adding some oats also make the crust more resistant so you can take your bars on the go + it’s a great way to make them a bit healthier so you don’t feel too guilty when you eat the whole batch by yourself because they are so good you just couldn’t share.

For the filling we use:

  • Apples
  • Lemon juice
  • Cornstarch
  • Sugar
  • Spices

Again, the spices add the kick. The lemon juice and cornstarch help to bind everything together so when you slice your apple bars they hold their shape.

Do you need to cook the filling before baking the apple crumb bars?

Not at all! That’s what I love about this recipe, there aren’t any extra steps complicating everything. Just place the filling over the crust, top it with extra crumbs and take everything to the oven to bake. 

Are the crust and crumble the same when making crumb bars?

Yes! I told you this was an easy recipe. The difference is that we are going to press tightly the crust so it really holds up. The crumble, on the other hand, is lightly sprinkled on top. 

Make a big batch – more like a HUGE batch – and freeze half for later, then just eat the rest for breakfast, snack and dessert.
