Is it okay to eat cake for breakfast? 

That is the life long debate, and I think it comes down to what ingredients you are using. My breakfast cake recipe fits the bill. It’s made with healthy, wholesome and heart-healthy ingredients, and also packs a protein punch. 

It uses healthy fats, low carb flour blends and is 100% naturally sweetened! 

Besides, even the scientists claim that eating dessert first thing in the morning is healthier for the body and the mind!

How to make a flourless cinnamon bun breakfast cake from scratch

The first step of this recipe is to combine all the dry ingredients and mix well. In a separate smaller bowl, you’ll want to whisk together the milk, flax eggs (or eggs!), before adding it into the dry mixture. Add the drippy and smooth almond butter (and syrup and applesauce for the paleo/keto option) and mix well. Then, you will bake the breakfast cake for either 25-30 minutes (vegan and eggless option) or 45-50 minutes (paleo, keto and gluten-free option) until it is golden brown on top and a skewer comes out clean from the center.

You’ll want to allow the cake to cool in the pan completely, before adding the optional frosting.

Tips for the BEST Cinnamon Breakfast Cake

  • Do not overbake the cake, otherwise, it will dry out. Remember, the cake continues to cook as it cools down.
  • Be wary of the different baking times. For the vegan/eggless option, it should take no longer than 30 minutes. For the paleo/keto/low carb option, no longer than 50 minutes. 
  • The cake MUST be cooled before frosting, or it will be too much like liquid/drippy. 
  • Do not substitute any of the ingredients in the low carb option- it will not turn out.
  • This breakfast cake makes a FABULOUS grab-and-go meal prep breakfast idea. Bake up 2-3 batches at a time and freeze the slices up- Check out the tips below on freezing them!

Can this breakfast cake be made as cinnamon roll breakfast 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.

  • Vegan, Flourless and Gluten-Free option– Bake for 18-20 minutes, or until a skewer comes out clean.
  • Paleo, Keto, and Low carb option– Bake for 25-30 minutes, or until a skewer comes out clean. 

Storing Cinnamon Bun Breakfast Cake

The cinnamon bun 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.

The breakfast cake is freezer friendly and can also be stored in the freezer. To freeze, wrap individual slices in parchment paper and place them in ziplock bags. Label them with the date 6 months in advance of the date it is baked. 

To enjoy breakfast cake from the freezer, allow thawing at room temperature or in the fridge overnight.

    1. I love brunch because it’s basically an excuse to eat breakfast for lunch and we all know that breakfasts foods are the best kind of foods. This has to be my favorite roundup that you guys have done so far, so much creativity and pure deliciousness! I am also really glad that I stoked up on 4 extra large containers of saigon cinnamon that are just waiting to be used up into all of your cinnamon bun concoctions!

    2. We have the most amazing brunch restaurant in town. You can sit there for hours and hours and hours and just shove all kinds of food in your mouth! I am a sucker for all buffets.
      I don’t know if I have already said that (if not, I was overwhelmed) this looks all kinds of lovely and my favorite picture is the half eaten one 😉

    3. Oh man every picture you posted made me hungry. I’m on a bit of a lemon kick lately so those muffins really got to me. SEND ME SOME.

    4. Go-to brunch: shakshuka, anything with poached eggs and greens, whole grain or GF pancakes/waffles, or anything else that sounds DELICIOUS! <3 It's been a while since I've had a traditional brunch though!
      I cannot wait to try this cinnamon bun cake! I'm already annihilating your blueberry junk yard cake!

    5. Hahaha our brains are so similar! I always say I love brunch but let’s be honest — I just like it because I feel like it’s an excuse to eat a bigger portion of all my favorite breakfast foods (eggs and potatoes or some combo involving one of those) plus occasionally a mimosa (or 6). The frosting on that cake looks heavenly! Frosting is my favorite part of any cake.

    6. Arman, please move here and open up a Brunch place with your recipes. Basel sucks at Brunch. I do not know what is wrong with these people. Avocado Toast with poached eggs or any kind of omelette (you already knew that.) for me fro brunch and yes, brunch IS the answer to anything in life.

    7. You’ve seriously blown me away with this one!!! I need a slice in my face ASAP! When do I come over and pick up 3498239 of these??

    8. That icing!! *heart eyes emoji*

      When I lived in DC, they were ALL about bottomless brunching. San Francisco has a solid brunch scene, less of a decadent/boozy scene and more of a “let’s meet after yoga and grab smoothies” brunch scene. I hate myself sometimes for being one of those people, but hey,it’s my life!
