Oat Crumble Topping

The streusel topping aka oat crumble topping is that crunchy, buttery, sweet crisp oat topping that sits on top of muffins, banana bread, coffee cake, crisps & cobblers.

It’s a delicious finishing touch to all kinds of baked goods and is a simple combination of butter, flour, oats, and brown sugar. Streusel is such an easy way to enhance any dessert and comes together so quickly, you’ll want to find any excuse to use it.

Streusel Topping vs. Crumble Topping

The difference between a crumble topping and a streusel topping is that you make a streusel topping with oats.

For this oatmeal streusel topping, there are oats in it, but you’re welcome to opt to make it without and it will be just as delicious!

Key Ingredients

Made with just a few simple ingredients that you most likely have stocked at home!

Streusel topping ingredients on the counter.

Find the full printable recipe with specific measurements below.

  • Oats: You can use instant oats, but I prefer the texture and chew of old-fashioned oats for this streusel. They give it a really nice bite and add a little bit of nuttiness.
  • Butter: I prefer salted because it saves me an extra step of measuring another ingredient and the salt helps enhance the flavors. The butter coats the oats and gives the topping the necessary moisture to keep everything together.
  • Flour: The all-purpose flour gives the streusel its crumbly structure and helps it hold its shape during baking.
  • Sugar: Brown sugar adds a depth of sweetness to the topping.
  • Cinnamon: I love adding a little cinnamon to give this streusel topping even more warmth.

Boost the flavor: Cinnamon or pumpkin pie spice are delicious spices that can be added to both a streusel and a crumble topping to add a little more essence of delicious fall flavors. Though, it can be used for any reason and on any occasion!

Helpful Tips

  • Gluten-free. To make this gluten-free, substitute with a 1:1 all-purpose gluten-free flour.
  • Type of oats. You can use old-fashioned or instant oats for this recipe. I do prefer the taste and texture of the old-fashioned oats.
  • Melt the butter. Melt the butter slightly so it combines easily and crumbles nicely without big chunks of butter.
