Summer is the best time for berries, isn’t it? Strawberries, raspberries, and blueberries are plentiful and always taste better at this time of year.

It’s the perfect season to make strawberry shortcake, blueberry nice cream, and these berry oat crumble bars.

These blueberry crumble bars are really easy to put together, which is why I usually go for a berry crisp or crumble rather than a pie. A pie involves much more time and work – making, rolling, and chilling the dough – but a crumble or crisp just involves mixing up the topping and baking everything. So easy, and that leaves me more time for other summer activities.

Ingredient Notes

  • Blueberries – You can use fresh or frozen blueberries here. Either will work well!
  • Oats – If you are gluten free, you will need to make sure you get certified gluten free oats. One brand to check out is GF Harvest, which produces their oats in an allergy friendly facility.
  • Sugar – I like brown sugar in this recipe, but if you are in a pinch, white sugar can work, too. You could use coconut sugar, but the color of the crumble will be a little darker.


  • If you want to make this recipe with different berries, you can! Try raspberries, strawberries, or blackberries, like in my blackberry crumble bars.
  • If you can’t have oats, you can try to make this with a mix of flour (or gluten free flour), and shredded coconut. The shredded coconut will give the topping texture.
  • I don’t recommend using oil in this recipe. Stick to using vegan buttery spread or regular butter if you are not dairy free.

Baking Tips

  • Lining the pan with parchment paper will help prevent the bars from sticking to the pan.
  • Make sure to let the bars to cool completely if you would like to cut these into neat squares.

Vegan Blueberry Crumble Bars (Gluten Free).

This is a super easy and delicious blueberry crumble recipe – a great dessert for summer! Enjoy with a scoop of ice cream, or just eat them plain.


  1. Preheat the oven to 375 degrees F.

  2. In a large bowl, place the gluten free oats, gluten free flour blend, vegan butter spread, and brown sugar. Use a pastry blender to mix it together. The mixture should resemble large crumbs, and there should be some balls of brown sugar and butter.

  3. Place half of the crumble mixture in the bottom of a 8×8 square baking dish. Use your hands to pat it down.

  4. Bake the bottom crust for 15 minutes. Remove from oven.

  5. Put the blueberries in the pan, and spread evenly over the crust. Top with the remaining crumble mixture.

  6. Bake at 375 degrees F for 25 minutes, until the berries are bubbling and the topping is golden brown.

  7. Let cool before slicing into bars.

Recipe Notes

You can store leftover bars at room temperature for 3 days. If you want to keep them longer than that, store in the refrigerator.

You can make these with different berries if you like. Try raspberries, strawberries, or blackberries.
