Why this recipe works
When you look for a basic crumble topping, you’ll often find recipes involving flour, sugar, and oats. I wanted a healthier and gluten free crumble topping, so I got to work! Instead of using typical flour, I use some of the oats and blend them into a flour. In place of sugar, I use syrup as a natural sweetener. The result is a delicious crunchy crumble topping perfect for your favorite fruit crumble!
Don’t stop with a berry crumble, though! Try this on a dutch apple pie, apple cobbler, or with some homemade jam on top of ice cream! An apple crisp with this oat crumble topping is not something you want to miss, either!
This was inspired by my Peanut Butter Granola, and pairs well with this amazing Pear Crumble recipe, Apple and Blackberry Crumble and Cashew Cream.
Ingredients to make Oat Crumble Topping
- Rolled Oats – I used gluten-free oats, but regular oats will work just fine. If you have some spare do try making my Baked Oats.
- Maple Syrup – is an excellent natural sweetener.
- Unsalted Butter – I used vegan butter to make a vegan crumble topping, but dairy butter will work as well.
See recipe card for full information on ingredients and quantities.
Substitutions
- Maple Syrup – Honey and agave syrup are both great substitutions for maple syrup.
Variations
- Deluxe – If you want to add a little extra flavour to this crumble recipe with oats, try adding cinnamon, chopped nuts, or a holiday spice.
- Kid friendly – this is already very kid friendly! Serve it up on their favorite ice cream, dessert, or even these Autumn Applesauce Pancakes.

How to make Oat Crumble Topping
Step 1: Put ⅔ of the oats into a blender for about 30 seconds until it blends into a flour.
Step 2: Combine the oat flour along with the rest of the ingredients into a large mixing bowl and mix together with your hands.
Step 3: Top it onto a crumble of your choice and bake.
Hint: Don’t limit yourself to fruit crumbles! Try this on top of oatmeal, a sweet bread, or even on it’s own with some ice cream!

Recipe FAQs
Yes – sort of! I take oats and blend them myself to make an oat flour. It gives the consistency needed without having to add a separate flour ingredient. To make the crumble mix oats with the oat flour, butter, and syrup.
A crumble topping with oats is typically used on top of a fruit crisp or crumble, but there are so many other ways to use it! It is great on top of oatmeal, muffins, pies, sweet breads, etc.
Cold butter is the best for making a crumble topping. It helps the topping to bind together at first and then spread perfectly in the oven.
A typical crumble topping is a combination of flour, sugar or brown sugar, and butter. I add in oats and blend some of them into my own oat flour. I also use maple syrup rather than sugar as it is a healthier replacement and just as delicious!

Oat Crumble Topping
Ingredients
- 240 g rolled oats, 3 cups (I used gluten-free)
- 2 tbsp maple syrup
- 75 g unsalted butter, (I use vegan)
Instructions
- To a blender add 160g (⅔ of the oats) and blend into a flour (takes 30 seconds).
- Add this oat flour to a separate large mixing bowl along with the leftover 80g of whole oats, butter, maple syrup and mix together with your hands.
- Top it on your crumble of choice and bake. I recommended baking at 180C/360F for around 25 minutes for the optimal oat crumble topping.
I haven’t tried making this recipe , because it doesn’t state what temperature to bake at – surely a basic essential to any baking instructions?
