I recently updated this recipe to also include tapioca starch for an improved texture.

Ingredients

  • Blueberries – You can use either fresh or frozen blueberries. If using frozen, there’s no need to thaw first.
  • Rolled oats – Not quick oats. For extra nutrition, use sprouted oats. Make sure they’re certified gluten-free!
  • Coconut sugar – This is one of the best easy sugar substitutes! If you prefer, you can use white or brown sugar instead.
  • Maple syrup – Provides a little more sweetness and depth of flavor and gives the topping a wonderful texture.
  • Oat flour Homemade oat flour or store bought. Make sure it’s certified gluten-free!
  • Almond flour – You can substitute almond meal which will give the topping a nuttier texture.
  • Coconut oil – Softened. If you don’t need the blueberry crisp to be dairy free, you can substitute softened unsalted butter.

Tips for Success

Use freshly squeezed lemon juice – It has a better flavor and avoids the preservatives in bottled lemon juice.

Don’t skip the tapioca starch – This thickens the blueberry mixture and prevents a watery filling.

Don’t over-mix the topping – Mix until just combined to create a crispy topping that’s not gummy.

Add the topping in chunks – For the best texture, don’t press the oat mixture onto the blueberry filling but drop it in small chunks. Don’t worry if it’s not perfectly even.

Allow time to rest – This gives the filling time to properly thicken for that rich, gooey texture.

FAQs

Yes, you can make blueberry crisp with frozen blueberries. For best results, don’t thaw them first, but bake from frozen.

How long does blueberry crisp keep?

You can store blueberry crisp in the fridge for up to 5 days. Reheat in the oven or enjoy cold.

Can I freeze blueberry crisp?

Unbaked blueberry crisp can be frozen, however, if you freeze it already baked, the topping will become soggy.
