Mad Creations Walnut Cinnamon Bun Keto Muffins #glutenfree #sugarfree #ketogenicdiet #ketodesserts #ketorecipes

If you love a good carrot cake or cinnamon bun you are going to love these very easy low carb walnut cinnamon keto muffins.

Spiced with cinnamon they are only subtly sweet. But, then they are topped with the most heavenly sugar free cinnamon buttercream. Damn I have to say they are just too good!

I love cinnamon on everything. I remember as a kid loving things like cinnamon toast and tea cake.

I guess the tea cake memory was what I was trying to achieve with this recipe. Anyway read on to learn a little more about how you can enjoy this fabulous keto dessert recipe.


  • 3 eggs (195g) egg total weight (less shells)
  • 80 ml MCT oil or liquid coconut oil
  • 50 g cream cheese
  • 1 tbsp cinnamon
  • 2 tsp vanilla extract
  • 2 tbsp Sukrin Gold granular sweetener I do love Sukrin Gold sweetener as it has that real malty rich depth to it like brown sugar (but without the carbs) Substitute Lakanto gold need be.
  • 300 g blanched almond meal I always use blanched almond meal but feel free to use almond meal made with the skins on as well
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder I always use Bobs Red Mill baking powder. It helps to give rise both in the cold and baking process.
  • 1/2 tsp salt
  • 50 g crushed walnuts – feel free to use any nuts if you have no walnuts or just dont like them

  • 1/2 tsp vanilla extract
  • 15 g lemon juice
  • 1 tsp cinnamon
  • 140 g powdered erythritol I use Sukrin Melis

It should really be noted that this is a very stiff batter and you will need to probably push it down into the patty cases.  Don’t fear the muffins do come out super light, moist and soft and not dense at all.

Another quick tip is to really give the keto buttercream a good whip so it comes out really fluffy and light. 

If it is still chunky and thick add a little more lemon juice or vanilla to make it a really billowy soft delicious buttercream.

    Can you substitute greek yogurt for the cream cheese in the recipe? Looking forward to making these but I do not use any of the fake sweeteners as they cause stomach issues but I do not need it very sweet.

  2. Helen

    Just make these. WOW!
    So easy in the thermo. I know how my sweetener works, so I used a bit less in the muffins and kept the same amount in the icing. Absolutely delicious for my taste.
    Thanks so much. How can one person be blessed with so much creativity. I love the way you put in all the extra notes and swaps. Very helpful.

    Hi! These look amazing. Is it possible to substitute the liquid coconut or MCT oil for anything else? I don’t have them on hand. Eg olive oil or butter? Thank you!

    I really enjoyed these, absolutely loved the icing. I had to keep some hidden away from my 3 girls so they didn’t eat them all on me!

    I made these to refill my depleted freezer stash of keto sweets…. but not before trying one 🙂 They are amazingly good!
    I made a half batch of buttercream which was the right amount for me. I might need the full recipe-worth if decorating for a special occasion.
    Great recipe!

    Absolutely delicious and moist muffins. They were so yummy I had to put them in the freezer so I didn’t eat them all. One of my favourite tasting muffins since starting LCHF/Keto. Make them. You won’t regret it

    These walnut cinnamon muffins are the perfect accompaniment to have with a nice cup of tea or coffee. They are great for kids and adults alike and perfect for the lunchbox. They are quick and easy to make and light and moist to eat. The cinnamon buttercream is delicious. These are already a family favourite.
