What can I say about this gluten-free cinnamon crumb cake? Yes, it is supposed to be a breakfast food but my friends and family love it so much, it has become the most requested dessert. One of my friends has nicknamed it with the name of a very addictive recreational substance. When I bring it to the kids at the camp I run, the room gets very quiet and the cake disappears.
Baking the Crumb Cake
This gluten-free cinnamon crumb cake does best when it is baked in a tube pan with a removable bottom. It really needs the help of the center tube to climb and hold it’s rise.
I personally do not have a tube pan – space in my kitchen is limited and I just don’t need one very often. So here is my solution. I use a 3″ tall 9″ cake pan and put a metal cup in the center. Feel free to improvise with what you have in your kitchen.
Cinnamon Crumb Topping
I include more crumb topping than most crumb cakes I have tried. In my opinion, if you are going to bother to make a crumb cake it should be mostly about the crumb! I also like to have some of the crumb in the cake. So I stir some into the cake batter once it’s in the pan, then top with the rest.
Gluten-Free Flour
I have used several different gluten-free flour blends for this gluten-free cinnamon crumb cake and they all worked well. My custom blend of sorghum, millet and brown rice flours with some starches is my favorite. My blog post on gluten-free flour blends has the recipe.
If you prefer a store bought blend, I like King Arthur Flour All Purpose Gluten-Free flour the best. I have included a super simple flour blend in the notes section in the recipe card. I highly encourage you to mix up your own gluten-free flour blend. It can be as much as half the price of buying a ready-made one. Vitacost.com is a great source for gluten-free flours. They have their own line of certified gluten-free flours at great prices.
Dairy-Free, Gluten-Free Crumb Cake
A couple of easy substitutions will make this gluten-free cinnamon crumb cake dairy-free. The sour cream in the cake can be replaced with vegan sour cream. I have tried it with Follow Your Heart vegan sour cream and the texture of the cake is a little bit different but still yummy. The butter in the cinnamon crumb can be replaced with coconut oil (virgin coconut oil is best) or vegan butter substitutes like Earth Balance. Butter subs tend to be salty so omit the salt from the topping recipe and expect the crumb to be more sweet and salty.

Make the Cinnamon Crumb Topping
- Melt the butter with the vanilla extract
- Combine the dry ingredients in a mixing bowl. Stir well and break up any brown sugar clumps.
- Add the butter-vanilla and stir until all of the dry ingredients are moistened.
Make the Sour Cream Cake
- In a large mixing bowl, whisk the dry ingredients together.
- In a separate bowl, whisk (or use a mixer) the eggs, vanilla, sugar, sour cream and oil. Whisk until the sugar is dissolved and the mixture is pale and creamy.
- Pour the liquid into the flour mixture and stir until smooth.
- Spread the cake batter into the pan. Top with 1/3 of the cinnamon crumb. Use a fork or spoon to press the crumb into the batter.
- Top with the remaining crumb and gently press down to adhere the crumb to the cake.
- Bake for 50 minutes or until a toothpick inserted in the center comes out dry.
Notes
