What You’ll Need for the Perfect Oatmeal Streusel Topping
Basic Oatmeal Streusel Topping
- Rolled oats: Old-fashioned oats work best for that chewy, hearty texture, but quick oats can also be used if that’s your personal preference.
- All-purpose flour: Regular flour works great here, but you can substitute whole wheat flour, gluten-free flour, or even almond flour for different results.
- Granulated sugar*: Cane sugar adds the perfect touch of sweetness. Make sure to select a vegan variety (see notes).
- Avocado oil: Any neutral-flavored oil (vegetable oil, canola oil) will work. Swap for melted vegan butter for a buttery streusel.

This recipe is as simple as it gets. To make this classic oatmeal crumble topping, just add the dry ingredients into a bowl then add the wet ingredients and stir until a crumbly texture has formed. That’s it!
This classic flavor pairs wonderfully with things like fruit crisps or muffins. The combination of dry ingredients creates a crisp topping that bakes up beautifully golden brown.
The quantity made in this recipe will be enough to cover baked goods in:
- One medium baking dish
- Two 9 x 5″ bread pans, or
- 12 standard muffins
If you are making more than these sizes or want the crumble topping to be thicker, consider doubling the recipe.
Delicious Variations to Try
Maple Cinnamon
For a variation without refined sugar, try this combination:
- Rolled oats
- All-purpose flour
- Cinnamon: Adds the perfect warm spice.
- Maple syrup: A natural sweetener that enhances the oat mixture.
- Avocado oil
The maple syrup adds moisture, so you might end up with a softer crumble—adjust the amount to your personal preference.

Apple Pie Spice
For a blend of cozy spices, this apple pie-inspired oat crumble topping is irresistible:
- Rolled oats
- All-purpose Flour
- Cinnamon
- Spices: cardamom, cloves, allspice, and nutmeg: A medley of warm spices that’s reminiscent of apple pie.
- Cane sugar: Or swap for light brown sugar for a deeper flavor.
- Avocado oil
This variation is the best thing to top a classic apple pie or Apple Cinnamon Oatmeal. It’s also a great way to add warm spices to your favorite recipes.

Brown Sugar Cinnamon
For a buttery streusel with a hint of caramel-like sweetness:
- Rolled oats
- All-purpose flour
- Cinnamon: Enhances the warm spice profile.
- Brown sugar: Dark brown sugar works too if you prefer a richer taste.
- Melted vegan butter
This crunchy topping is ideal for coffee cake or the top of muffins. Serve it warm with a scoop of vegan vanilla ice cream for a dessert everyone will love.

More Options for Add-ins:
- Seeds: Hemp seeds, chia seeds, or pumpkin seeds would pair perfectly with this crunchy topping
- Chopped Nuts: Chopped walnuts or slivered almonds would add a hearty flavor to these toppings
- Fruit: Add 1 tbsp of your favorite jam or jelly to this mixture for a fruity twist.
Tips for the Perfect Streusel Topping
- Mixing Method: Use a large bowl to combine the dry ingredients. Add the wet ingredients and mix until the oat mixture forms a crumbly texture. If the mixture feels too dry, add a splash of lemon juice or a touch more oil.
- Storage: Store any unused streusel in an airtight container at room temperature for up to 3 days or in the fridge for 5-7 days.
- Baking Tip: Spread the streusel evenly over your favorite muffins, quick breads, or fresh fruit before baking. Bake until golden brown for the perfect crunchy topping.
- Not Vegan? Use melted butter instead of oil or vegan butter in these recipes.
- Gluten-free? Make sure to select a gluten-free variety of oats and gluten-free baking flour.
FAQ
This recipe could be considered both a crumb topping and a streusel topping. Crumb toppings tend to have more sugar and may be more coarse than streusel. Streusel toppings may include ingredients like nuts and are sometimes finer texture.
Add a pinch more flour to recipes that have a lot of fruit or other liquids so the topping absorbs less and gets crispier in the baking process.
Yes! You may notice a slight difference in texture, but quick oats are a fine replacement in this recipe.
