Can we please talk ALL THINGS Lemon Blueberry Crumble Bars? These delicious dessert bars are seriously one of my favorite things to make in the whole wide world.

Crumble Bar recipes may look intimidating to make, but it’s actually quite easy. Think of it as a two part recipe. You’ve got your delicious crust and crumble and then the fruit filling. Let’s talk crust, first.
Sugar Cookie Crust
If the crust was a stand-alone recipe, I wouldn’t be mad at all. It’s buttery and perfectly sweet just like every pie bar should be. It’s made with an almond meal/oat crust and sweetened with honey. Here’s what else you need:
- Almond meal
- Rolled oats
- Coconut oil
- Honey/Maple syrup
- Vanilla extract
Crust tip: If you’re hoping to keep the crust 100% gluten-free, make sure that you use certified gluten-free oats. And, if you’re wanting to keep this recipe vegan, you can sub maple syrup in for the honey!
The blueberry filling is where this blueberry dessert recipe gets tasty. Start off by heating blueberries, water, lemon, honey, and tapioca over medium heat and let the magic happen. The mixture becomes thick and gooey, the perfect consistency for blueberry crumble bars. If you’ve never heard of tapioca flour, it’s very similar to cornstarch in that it’s a thickener. This is an essential ingredient to getting that thick consistency you crave when it comes to a dessert bar. Here’s what you need:
- Lemon juice
- Lemon zest
- Honey (option to sub maple syrup for vegan option)
- Tapioca flour
Filling tip: try swapping the blueberries out for a different berry or fruit for a yummy, creation of your own!
Blueberry Bars Storage
We recommend storing your crumble bars in an airtight container in the fridge. These will last you anywhere from 3-5 days if you don’t eat them first!
