Keto Cinnamon Sugar Donuts

With a name that includes sugar, you may be wondering how on earth they can be low-carb donuts. Well, rest assured that these lovely donuts are void of sugar.

The use of a monk fruit sweetener makes sure that these stay within your keto macros and in ketosis. 

These cake donuts have a moist, tender crumb thanks to the addition of sour cream. This also gives them that old-fashioned flavor we know and love.

I opted to use a combination of almond and coconut flour because it also plays a role in getting the perfect cake donut texture.

How To Make Keto Cinnamon Sugar Donuts

Don’t you love it when a recipe comes together quickly? Well, that’s what this fuss-free keto donut recipe provides.

To make your low-carb cinnamon sugar donuts, you’ll need to preheat your oven to 350 degrees and properly grease your donut molds.

I used a silicone donut pan, but you can use a non-stick donut pan if you prefer.

You’ll combine the dry ingredients—the almond and coconut flour, sugar substitute, baking powder, cinnamon, nutmeg, and salt—in a large mixing bowl.

In a separate bowl, add the sour cream, melted butter, whole eggs, and vanilla extract and combine well. I recommend you use an electric mixer to ensure the batter is well incorporated.

Then, add the wet ingredients to the wet ingredients and combine well.

Next, to easily add the batter into the donut molds, I recommend using a piping bag or placing the donut batter into a large ziplock bag and snipping off the tip of one of the corners.

I like silicone molds, but a non-stick donut baking pan will also work. In both instances, you will need to grease the cavity of the molds.

To ensure even baking, I place my silicone molds on a cookie sheet. This also makes it easier when it comes time to take it out of the oven. 

The bake time will be around 25–30 minutes. Bake until golden brown and when an inserted toothpick comes out clean.

After the donuts are baked and cooled, you’ll make the icing and then allow the icing to set by placing your donuts on a baking rack.

Sugar-Free Sweetener Options

As far as which sugar substitute to use for these keto cinnamon donuts, I have a few recommendations. If you are a regular on our site, you know I’m a fan of Lakanto Monk Fruit.

This is because the texture of Lakanto is spot on since there is barely any aftertaste. It is a monk fruit and erythritol blend.

In the case of this low-carb donut recipe, I went with their brown sugar substitute for the donut batter and their white granulated sugar substitute for the cinnamon sugar topping, but feel free to use either one entirely in the recipe.

I love that Lakanto Monk Fruit is all-natural. Its sweetness comes from antioxidants called mogrosides instead of fructose or sucrose. It has zero calories and zero glycemic impact. 

I’m also partial to Swerve, another erythritol blend.  It works well in this keto donut recipe and is a great choice if you are looking for a sugar substitute with no bitter aftertaste and measures just like sugar.

Swerve is also a sugar substitute that browns and caramelizes like sugar. It is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

Like Lankanto, Swerve has a 0% impact on blood sugar.

If you are a fan of stevia, you can use the stevia and erythritol-based brand Pyure in this recipe.

However, it’s important to note that if you use Pyure, you will want to use half the amount called for in this recipe since it’s a much sweeter option.

I will also add that if using a stevia blend, you will use less of the sugar-cinnamon coating to avoid it being overly sweet.

I sure hope you will give this keto cinnamon donut recipe a try.
