I was never that much of a donut person growing up. I knew plenty of people who were obsessed with them, but I could take them or leave them. That is until I invested in a donut pan and started making my own keto donuts. My kids love them and I have so much fun playing with ingredients and flavors. It is a wonderful outlet for my baking creativity.

Believe me when I say that these glazed Keto Lemon Donuts are as delicious as they are pretty!

In my many years of experimenting with keto baking, I have found that coconut flour is excellent for making donuts. People are often intimidated by baking with coconut flour, because it doesn’t behave like any other ingredient on the planet. But with a little coaxing, the results can be light, fluffy, and ultra-tender.

My Keto Chocolate Donuts are coconut flour-based, and readers rave about them. So I knew it was just the thing for whipping up some delicious low carb lemon donuts too.

What readers are saying…

“I made these this weekend and we LOVED them. I also took them to work for my non keto co-workers and they had no idea they weren’t “real donuts”. I am a huge fan now! Thanks so much for all you do.” — Tammy

Ingredient Notes

  • Coconut flour: Different brands can vary quite a bit in absorbency so I recommend using Bob’s Red Mill. It is always very reliable and consistent.
  • Protein powder: As with other baked goods like keto muffins, a little protein powder helps the donuts rise nicely and hold their shape. Whey or egg white work best in this recipe.
  • Sweetener: You will need a granular sweetener for the donuts and a powdered sweetener for the glaze. See the Tips section for more details about sweeteners.
  • Lemon: This recipe uses both lemon zest and lemon juice.
  • Lemon extract: A little lemon extract helps boost the bright flavor.
  • Heavy cream: I used some heavy cream in the glaze to make it thick and rich.
  • Kitchen staples: Butter, eggs, baking powder, vanilla extract, and salt.

How to Make Keto Lemon Donuts

  1. Combine the dry ingredients: Whisk together the coconut flour, protein powder, sweetener, baking powder, and salt.
  2. Add the wet ingredients: Stir in the eggs, butter, lemon zest, lemon juice, and the extracts. Add water as needed.
  3. Bake the donuts: Divide the batter among the wells of the donut pan and bake until the donuts are set and firm to the touch.
  4. Let them cool: Remove and let cool in the pan for 10 minutes. Transfer onto a wire rack to cool completely.
  5. Make the glaze: Whisk together the sweetener, cream, and lemon juice. Dip the donuts or drizzle overtop.
  6. Serve and enjoy!

There is no standardization in donut pans and the size of the wells can vary a lot. I have a good pan from USA Pan that is non-stick and non-toxic that I love. It makes 6 good-sized donuts, so I highly recommend it!

No matter what pan you use, grease it well. I also recommend loosening the donuts from the pan after about 10 minutes of cooling. I find that they start to stick again if you leave them too long. I use a thin-bladed silicone spatula to loosen them.

I don’t specify an exact amount of water because it depends so much on the coconut flour. You may need more or less depending on what brand you use. Add just a few teaspoons at a time, stirring until you have a batter that is thick but easily scooped into the donut pan.

Sweetener Options

The sweetener you choose to use will affect the outcome of the donuts. For the donuts themselves, I highly recommend an erythritol-based sweetener. Anything with allulose will make them brown too quickly, and they will be too soft and fragile. If you prefer not to use erythritol, try sweetening them with pure stevia or monk fruit extract.

The glaze requires a powdered sweetener, but both allulose and erythritol work. I used a combination of both.

    Delicious, very crumbly, mine fell apart when I dipped them in the icing! Any suggestions?
    I followed directions.

    1. They can be fragile if you don’t let them cool completely! But what brand of coconut flour did you use?
