Cinnamon Breakfast Cake

I love starting my mornings with something full of cinnamon. If I’m not having cinnamon roll oatmeal or a fluffy cinnamon roll, you know I’ll be having a slice of this cinnamon bun cake. 

Is it weird to have cake for breakfast? As someone who always starts their morning with a sweet breakfast, the concept isn’t too far fetched. My ideal breakfast is something that incorporates whole grains, healthy fats, and a moderate amount of protein. If that comes in the form of cake, you can bet it will make my breakfast plate!

This cinnamon cake is acceptable to enjoy for breakfast, and is secretly healthy! Unlike traditional cakes, this cinnamon one is made without butter, without flour, and without eggs! However, you’d never be able to tell. Taste wise, it’s full of sweet, cinnamon flavor, and with a gorgeous healthy frosting. The texture is perfect- moist, fluffy and with a tender crumb.

Naturally vegan and gluten free, it can easily be made keto too!

Ingredients to make this cinnamon bun cake

These are the ingredients you’ll need to make this recipe. See my tips below for tested substitutions and a tested keto option. 

  • Rolled oats– The oats will be blended to a flour texture. Be sure to use certified gluten free oats, if needed.
  • Granulated sweetener of choice– Any granulated sweetener can be used. I used coconut sugar for this particular cake. 
  • Baking powder– Gives the cake some rise and fluffiness. 
  • Salt– Brings out the sweetness of the cake. 
  • Egg OR flax egg– You can use either an egg or if you are plant based, a flax egg. To make a flax egg, combine 1 tablespoon of ground flaxseed with 3 tablespoons of water. Let it sit for 10 minutes, for a gel to form. 
  • Vanilla extract– A must for any good cake or baked good recipe! 
  • Almond butter– Smooth and drippy almond butter, with no added sugar or salt. 
  • Milk of choice– I used unsweetened almond milk, but any milk can be used. 

How do you make a cinnamon cake? 

In a high speed blender or food processor, add your oats and blend until a very fine, almost powder-like consistency. Add the rest of your ingredients and blend well, until a thick batter remains. Transfer your batter into an 8-inch cake pan and bake for 25-30 minutes, or until a skewer comes out the center clean. Remove from the oven and let the cake cool in the pan completely, before frosting it.

Trouble Shooting and Tips and FAQ’s 

Can I make this cake as muffins?

If you don’t have a loaf or baking pan and want these as muffins, that can easily be done! Simply prepare the batter as directed and divide them amongst 12 muffin tins. The baking time will need to be adjusted.

Check your muffins around the 18-minute mark, and remove once a skewer comes out clean from the center. 

Why is my cake dry? 

Avoid risking a dry cake by ensuring your oats have been blended to a powder-like consistency. Any course pieces or larger flakes will dry out the cake batter. 

What frosting can I use?

I used my cream cheese frosting but added 1/2 teaspoon of cinnamon in it. You can use any frosting you like or keep it unfrosted. 

Tested Ingredient Substitutions

  • Rolled oats– You can use straight oat flour or 2 cups of your favorite all purpose flour. 
  • Almond butter– Any drippy/smooth nut or seed butter can be used. Peanut butter, sunflower seed butter, and smooth tahini are all fantastic options. 
  • Granulated sweetener– White sugar, brown sugar, monk fruit sweetener, or erythritol. 

Can I make this recipe keto or paleo? 

If you’d like to make a keto breakfast cake, here are the ingredients and instructions you’ll need to make that. 

To make: 1/2 cup coconut flour, 1 tablespoon cinnamon, 1 cup unsweetened applesauce (or pumpkin puree), 1/2 teaspoon baking soda, 1/4 cup maple syrup (or keto maple syrup). 1/4 cup smooth almond butter, 1 tsp vanilla extract, 4 large eggs.

Mix the dry ingredients together. Add the wet ingredients and mix well, until combined. Transfer to a cake pan and bake for 45-50 minutes.

Tips for the Best Breakfast Cake

  • The ingredients and proportions make a single layer cake with frosting. If you’d like to make the cake as pictured, triple the ingredients and distribute the batter amongst 3 cake pans. 
    Do not overbake the cake, otherwise, it will dry out. Remember, the cake continues to cook as it cools down.
  • The cake MUST be cooled before frosting, or it will be too much like liquid/drippy. 
  • Do not substitute any of the ingredients unless specifically stated. 

How to store cinnamon cake

  • To store: The breakfast cake must be stored in the fridge, otherwise, it will become rancid and spoil easily. Place the sliced and frosted cake in a sealed container. It will keep fresh for 5 days.
  • To freeze: Place slices of the cake in a sealable container and store in the freezer for up to 6 months. Thaw overnight in the refrigerator.

    1. Hard to believe but you once more managed to get even me as a non-cake fan intrigued. It must be the thick layer of frosting ;). I’d eat it with a spoon. Actually, that’s what I used to do when I was younger: eat the frosting off my mum’s cake. Now that I’m older I skip the cake part and just prepare the topping to eat straight up and call it a snack. So classy.

    2. Oats again ! This is wonderful! You are def on an oat roll Arman! And that topping (in order to lay low I will call it topping since frosting is a dead giveaway for upping the pounds) is to DIE for…thank you, thank you, thank you! I MUST Google SAIGON CINNAMON – have never heard of this before…if all I have is powdered cinnamon in a spice type container, will that kill this recipe? 🙁

        1. Okay thanks for that…I Googled Siagon Cinnamon – very interesting – BTW another really great side effect to following Arman here is the great NEW stuff I learn all the time! So now am on a search for SAIGON CINNAMON – first stop our local health/bulk food shop in our wee town…and then on to various markets around…and then to the next town where there are a few more health food type shops – from there to the BIG city – or maybe just skip all that and get it online! Yeah that might work better….Thanks Arman!

    3. Wait just a hot pickin’ second there, mate. A cinnamon bun that’s a cake? Say what? As strange as it might sound, I think I can get behind this one. It looks incredible…and I want the whole darn loaf. For breakfast. 🙂

    4. Thank you so much for listing so many options of how to make this. It sure makes things easier for those who have multiple food sensitivities. ?
