Want to introduce little ones to baking? Try these Keto Cinnamon Sugar Muffins. They’re easy to make and perfect for breakfast or as an after-school treat.

I loved making muffins with my daughter on the weekends when she was little. It was one of the first things I taught her to bake. Even now, we often whip up a batch together when she’s home from college. It’s still one of our most beloved mother-daughter bonding traditions.
As you can imagine, I’ve amassed quite a collection of muffin recipes over the years, but only recently have I started giving some of my classics a keto makeover. Take this delicious recipe for cinnamon sugar muffins, for example. They’re every bit as tasty as my original version—but instead of all-purpose flour, I’ve used almond flour, and I’ve swapped the processed sugar for a sugar-free sweetener (I use a blend of monk fruit and erythritol). Are we missing out by keeping it keto? Not at all!
Whether you’re enjoying a lazy Saturday morning or hosting brunch, these moist keto cinnamon sugar muffins will delight with their tender crumb and sweet cinnamon flavor. They’re a breeze to prepare and such a fun recipe to make with kids of all ages. In fact, guess what my 20-something daughter and I are baking for brunch this weekend? Too old to bake with mom? Never!

Tips for baking with children
Baking muffins with children is a wonderful way to introduce them to the joys of cooking. A recipe like this one is perfect because it doesn’t require knives or heavy-duty kitchen equipment. Kids can help measure the ingredients, crack the eggs, mix the batter, and fill the muffin cups. With this recipe in particular, they’ll especially love brushing the muffins with melted butter and rolling them in cinnamon sugar.
The key is to make the activity fun. Set aside plenty of time, and don’t stress about a messy kitchen or flour-covered clothes. Why not even buy special matching aprons to make the occasion even more memorable? Focus on enjoying the moment together, not on achieving perfection.

How do I store leftovers?
Once they’ve cooled, store these muffins in an airtight container at room temperature for up to 3 days or in the fridge for up to 5 days. For longer storage, double-wrap them in plastic wrap, transfer them to a resealable bag, and freeze them for up to 3 months. Thaw at room temperature or in the fridge. You can heat them up in a toaster oven or microwave.

Keto Cinnamon Sugar Muffins
Ingredients
For The Muffins:
- 5 tablespoons butter softened
- 1 cup powdered sugar-free sweetener
- 1 teaspoon vanilla
- 2 eggs
- 1/2 cup half-and-half
- 1 1/2 cups almond flour
- 1 tablespoon ground flaxseed
- 2 teaspoons baking powder
- 1 teaspoon cinnamon
- 1/2 teaspoon ginger
- 1/2 teaspoon nutmeg
For The Cinnamon Sugar Topping:
- 1/2 cup granulated sugar-free sweetener
- 2 teaspoons cinnamon
- 4 tablespoons butter melted
Instructions
- Preheat oven to 350°F and grease a 12-cavity muffin tin with nonstick spray.
- In a medium-sized mixing bowl, beat together the butter, powdered sweetener, and vanilla.
- Add the eggs and half-and-half. Mix well and set aside.
- In a separate mixing bowl, whisk together the almond flour, flaxseed, baking powder, cinnamon, ginger, and nutmeg.
- Fold the dry ingredients into the wet until well combined.
- Evenly distribute the batter among the muffin tin cavities, filling each about 2/3 full to leave room for rising.
- Bake for 18 to 20 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the muffins to cool in the pan for 10 minutes before transferring them to a wire rack to cool for an additional 20 minutes.
- While the muffins are cooling, make the cinnamon sugar topping by combining the granulated sugar-free sweetener and cinnamon in a small bowl.
- Once the muffins have cooled, brush them with the melted butter on all sides and roll them through the mixture of cinnamon and sweetener.



These are SO good. I made them mini. I stopped dipping in butter, just rolled them in cinnamon sugar. Will definitely make again.
So glad you enjoyed these muffins! Can’t wait to hear about your next batch! 🙂

This was unbelievably good. I dont find alot of keto recipes that i like, and this one I loved. I did however use Mixed spice(pumpkin spice) instead and didnt have flaxseed so used Psyllium. I also chose to just melted butter over them when they came out of the oven… Thank you, after a weekend of epic failed keto recipes, my faith is restored again!
So glad you enjoyed this recipe! Thanks for reading.
I I made these and they do taste very good. G
However, I not sure what I did wrong. I used the small muffin tin. 12 muffins to a tin. Batter was soft and the muffins are crumbly. Too much liquid? I really like these and will try again just not sure what I missed. I did use monkey fruit. Really like that sweetener. Please advise.
Hi Marlene, You could try reducing the half and half slightly or adding a bit more flaxseed to improve structure. Keep me posted please!
Wow! My muffins came out great! Very moist and delicious. Thanks!
So glad to hear! Thanks for reading.
I’m trying to stay away from saturated fats (not following keto diet) although trying to eliminate carbs, and wondering if I can replace the butter with olive oil in the batter?
Hi Cindy, Yes, you can replace the butter with olive oil in the batter. Use about 4 tablespoons instead of 5. It will slightly change the texture but still works well.
I don’t have half & half. Can i use heavy whipping cream instead?
Hi Cheryl, Yes, you can but you may want to dilute it with a little water (about ¾ cream + ¼ water) to match the consistency.
These are just the thing to help when you are having cravings for something sweet! I love muffins and donuts so this is the perfect combo to satisfy both! I do a bit less stevia than the recipe asks for in the muffin because there is enough sweetener in the top to complete it.
Glad to hear you liked this recipe! Thanks for reading.
Made these 3 times so far. There will be many more times in the future. Excellent!
They make me look forward to my breakfast.
So glad you love this recipe! Thanks for reading.
This is similar to a recipe I found online wayyyyyyyyy back when I did Atkins years ago- now I’m Keto so I pulled out my old cookbook and have been making them again. Yours has a few different tweaks and less liquid, so I’ll try it and see how it compares to my old one.
BTW, I also make blueberry lemon muffins using (my old recipe) and just added blueberries and lemon peel instead of the nutmeg and cinnamon. I made a simple lemon glaze for the top. Turned out great!
This sounds really good though, so I’ll be trying your recipe this week. Thanks!
That sounds amazing Ruthi. Hope you enjoy this version too when you give it a try!
I just made them and prefer them to my old recipe. They’re great. Thank you!
Great
