These cake donuts use sour cream in the batter to ensure a moist, tender crumb. It also adds a very slight tang that gives them that old-fashioned quality.

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

The addition of a bit of ground nutmeg gives them an added flavor distinction. If that’s not enough, these keto donuts also feature a vanilla glaze that makes them irresistible.

How To Make Keto Old Fashioned Donuts

These keto donuts come together quickly. Once you have preheated your oven to 350 degrees and greased your donut molds, it’s then simply a matter of mixing your dry and wet ingredients together.

First, combine the almond and coconut flour, sugar substitute, baking powder, nutmeg, and salt in a large mixing bowl.

To these dry ingredients, you’ll then add the wet ingredients: sour cream, melted butter, whole eggs, and vanilla extract, and combine well. I use an electric mixer to ensure the batter is well incorporated. 

To easily add the batter into the donut molds, I recommend using a pastry piping bag or placing the donut batter into a large ziplock bag with the corner snipped off.

I like using a silicone donut pan, but a non-stick donut baking pan will also work. In both instances, you will need to grease them well.

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

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

Sugar-Free Sweetener Options

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

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

I love that Lakanto Monk Fruit is all-natural, and it gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. And 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 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.

This makes it a great option for anyone on a ketogenic diet.

If you are more of 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 are using Pyure, you will want to use 1/2 the amount called for in this recipe since it’s a much sweeter option.

Lastly, if you cannot easily find a more natural sugar substitute, you can also use Splenda with great success.

You will need a confectioner’s sugar substitute for donut icing. Thankfully, both Lakanto and Swerve have great ones.

This recipe for keto sour cream donuts makes a tender cake donut that is lightly spiced with nutmeg for the flavor profile of old-fashioned donuts we all remember and love.

  1. Preheat the oven to 350 degrees.
  2. Grease well two 6-cavity donut pans.
  3. Melt 1/4 cup unsalted butter and set aside.
  4. In a large mixing bowl, combine the almond flour, coconut flour, sugar substitute, baking powder, nutmeg, and salt until well combined.
  5. To the dry ingredients, add the sour cream, melted butter, vanilla extract, and the 3 eggs one at a time.
  6. Mix the batter using an electric mixer until fully incorporated. 
  7. Pipe the batter into the two prepared donut pans with a pastry bag or a large ziplock bag where the corner has been cut. Pipe the batter into the donut pan cavities. 
  8. I lightly tapped the batter into the donut pans using my fingers.
  9. Note that you will fill the donut pans just to the rim because these donuts do not rise much.
  10. Bake donuts for 25-30 minutes until donuts are fully cooked. You can insert a toothpick, and it comes out clean.
  11. Allow the Keto Donuts to fully cool at room temperature before removing them from the mold.
  12. Once the donuts are removed from the donut mold, place them on a baking rack and proceed to make the icing.

  1. Melt the butter and add to a medium-sized bowl.
  2. To the bowl, add the confectioners, sugar substitute, vanilla extract, sea salt, and nutmeg.
  3. Mix well, and then add the hot water. Start with three tablespoons and add the additional tablespoon if the consistency is too thick.
  4. Quickly dip the donuts into the icing and set them on a baking rack to dry. The donuts will form a thin frosted shell on the surface.

Store Your Donuts

  1. Once the donut's icing has been set, store them in the refrigerator in a sealed container for up to 5 days. You can place the donuts on top of each other since the icing hardens. You can also freeze your donuts by placing them in a freezer-proof container for up to 3 weeks.
  2. Allow your donuts to come to room temperature for the best flavor.

Just made these sour cream donuts today and they are delicious. One question/issue I had was with the icing. Is it supposed to be 3 tablespoons hot water or 3 teaspoons? I added 2 tablespoons, mixed it to check consistency, and it was already too thin to be an icing and wound up being more of a delicious “soak”. I will make these again and be light handed with the added moisture for the icing next time. Thank you for this delicious recipe!

Hi Melanie, The recipe calls for 3-4 tablespoons of hot water not sure what brand of confenctioner's sugar substitue you used, perhaps that was the difference. Glad you enjoyed the donuts!
