Ingredients

Below you’ll find the full list of ingredients needed, plus some ingredient notes!

Ingredients for peach blueberry crisp arranged close together on a wooden board.

Blueberries: I love using fresh blueberries for crisp, but you can certainly use frozen blueberries if you don’t have fresh ones!
Peaches: be sure to use fresh juicy peaches, if they’re harder they won’t soften as much in the oven. You can use frozen peaches too! But fresh is always best.
Coconut sugar: I like to use this as a natural sweetener, but if you don’t have it swap for brown sugar or maple syrup!
Coconut oil: instead of butter, I like to use melted coconut oil as the fat and binder for the topping. If you don’t have coconut oil, use vegan butter for a plant-based option, or regular unsalted butter if you don’t need it vegan.
Cinnamon & vanilla: to add flavor to the oatmeal topping!
Oat flour: my favorite healthy flour alternative made from ground-up oats! If you don’t have this on hand, see our notes below on how to make it. If you prefer not to use oat flour you can swap it for almond flour!
Whole or quick oats: use regular oats or quick oats as the topping!

Top Tips for Success

Frozen versus fresh fruit – Both work for this recipe! But I love using fresh fruit. If you were to use frozen blueberries, I love using frozen wild blueberries because they’re super sweet and really flavorful when baked!

Make it gluten-free – If you need this recipe to be gluten-free friendly, be sure to use gluten-free oat flour and oats!

Best ways to serve a fruit crisp – our favorite way to serve this crisp is warm (preferably fresh from the oven) and with a scoop of cold vanilla ice cream!

Add nuts! For a little bit of texture, you could also add 1/2 cup of chopped walnuts or pecans to the crumble mixture before baking.

How long does it keep for? Leftovers for this recipe keep fresh for about 5-7 days.

How do I reheat it? The best way to reheat this recipe is in the oven covered at 350F until the crisp is warm. Several minutes in the oven is all that’s needed. I personally don’t own a microwave, but that works too!

How to Make Oat Flour at Home

If you can’t find oat flour at your local store you can easily make it at home! Use either a food processor or high-powered blender, add oats (quick oats or whole oats) and blend until the consistency is super fine and flour-like.

You can make it ahead of time and keep the oat flour stored in an airtight container in your pantry for future recipes!
