This Gluten-free Banana Crumb Cake is the most dreamy banana bread coffee cake with a crumb topping. The easiest crumb cake recipe for brunch, dessert or a sweet breakfast treat that is both nut-free and gluten-free.

If you are looking for a delicious brunch idea that is perfect any time of the year – look no further than this Banana Crumb Cake! It’s like a coffee cake meets banana bread with a dreamy crumb topping. And we are *hooked* on this in our home. We have it for dessert, brunch or breakfast. And it is such a great way to use up leftover bananas that are ripe too.

And I love that this is a great make ahead brunch idea too. Banana bread + crumb cake = pure bliss!

This recipe is also dairy free-friendly too if you use a vegan butter and non-dairy milk. And it is gluten-free since we are using gluten-free all purpose flour. The base is a delicious banana bread base and the topping has chunky cinnamony crumbs and then we drizzle a powdered sugar glaze on top that’s made with just 2 ingredients.

Tip: use extra ripe bananas so it is extra moist and sweet! The more freckles on the bananas the better.

What ingredients you need to make banana crumb cake:

  • Cold unsalted butter – cut into small cubes and you use vegan butter to keep this dairy-free if you want too!
  • Gluten-free all purpose flour – if not gluten-free than you can use an all-purpose flour instead too
  • Coconut sugar – I recommend coconut sugar as the unrefined sugar option here for the cake and the flavors and textures together are delicious!
  • Cinnamon – lots and lots of cinnamon is needed here!!
  • Eggs – I haven’t tested a flax egg or egg replacer but it should work well
  • Milk of choice – you can use any milk you want! Coconut, almond, cow’s milk, etc.
  • Bananas – ripe bananas are best. The kind of freckled you’d use for banana bread

How to make banana crumb cake:

  1. Preheat oven to 350 degrees F and grease an 8 or 9-inch round cake pan well
  2. In a medium bowl, use two forks to crumble together the cold butter cubes, flour, sugar, and cinnamon until the mixture resembles a crumbly topping. Set aside the crumb mixture
  3. In a large bowl, cream softened butter on medium with hand mixer until creamy
  4. Add the sugar and mix for another minute, until well incorporated
  5. Then add the eggs, vanilla, milk and mashed bananas and mix just until ingredients are combined
  6. Add in flour, baking powder and cinnamon and mix until fully combine
  7. Pour cake mixture into the prepared baking dish and top with the crumb mixture
  8. Bake for 50-55 minutes, until a toothpick comes out clean
  9. Next make the glaze by whisking together the powdered sugar and milk
  10. Cool the cake at room temperature for 5-10 minutes before drizzling the glaze over the top then slice and enjoy!
