Make a single keto donut in about 10 minutes with this recipe for a delicious old-fashioned cake donut you'll want to sink your chompers in. It's even topped with a luscious vanilla cream glaze and colorful sprinkles.
What makes this recipe different?
- Portion controlled – Designed to produce just one perfectly portion-controlled donut, this is the best solution to enjoy a donut without leftovers tempting you for days. Acutally, I get sick of eating the same thing over and over – that’s why I love single serve recipes!
- Only takes 10 minutes – Since we are only making one donut, this keto donut recipe doesn’t require a lot of effort, time or dishes to dirty.
- Keto friendly – Instead of using flour and sugar like the key ingredients found in traditional donuts, this recipe uses almond flour, protein powder and sugar free sweetener, keeping it low-carb and only 2.5 net carbs for one donut!
- No eggs necessary – Most low-carb donut recipes require eggs, but with this recipe, I realized it wasn’t a necessary ingredient. They will rise and puff up when fried without the egg.

Step by Step Instructions
Step by Step Instructions
Mix the dry ingredients
In a small bowl, whisk together almond flour, protein powder, sweetener, baking powder, xanthan gum and salt.
- 1/4 cup almond flour
- 1 tablespoon protein powder
- 1 teaspoon sugar-free sweetener
- 1/4 teaspoon baking powder
- 1/4 teaspoon xanthan gum
- pinch of salt
Mix in wet ingredients
Stir in melted butter, sour cream and hot water. Let sit for 2-3 minutes, while you heat up the oil.
- 1 tablespoon unsalted butter, melted
- 1/2 tablespoons sour cream
- 1/2 tablespoon hot water
Melt the lard
Add enough lard to your smallest skillet to cover the donut at least half way. About ½ inch or so. Heat lard over low heat.

Play with your food
Roll the dough into a ball and place on a sheet of parchment paper. Using your index finger, punch a hole in the center and move your finger in small circles to create the donut shape. Make the hole a little bit wider than a typical donut since the donut will puff out as it cooks causing it to expand in the center, closing in on itself.
Check your oil
To check if the lard is hot enough, toss a little piece of leftover dough from the bowl into the skillet. If it sizzles, it is ready.
Fry the donut
Use a spatula to remove the donut from the parchment paper and lower it into the oil. Swirl or tilt your skillet around gently to help cover the sides and encourage it to cook. Check the donut after about 1-2 minutes to see if the underside is golden brown. Once it is, then carefully flip. Let cook for 2-3 minutes or until golden brown. Remove and place on a paper towel lined plate.
Make the glaze
Prepare the glaze by mixing powdered sweetener with 1-2 teaspoons of milk and vanilla. Add more milk if needed to get a liquidy glaze. Dip the top of the donut in the glaze. Then top with sprinkles.
- 2 tablespoons powdered sugar-free sweetener
- 1-2 teaspoons milk of choice
- 1/4 teaspoon vanilla extract
- sprinkles

Tried this donut recipe today and was pleasantly surprised by how moist and flavorful it turned out. I used a dash of cinnamon to give it a little extra warmth. Super happy to find a low carb treat that doesn’t taste like one.
I decided to try this, only to realize I didn’t have sour cream. I used greek yogurt instead and it was very good!
Oh. My. Freaking. Goodness. This recipe is incredible!! These single serve keto fried donuts are literally a kitchen-made miracle. You have no idea how many times I’ve searched for good keto desserts, and ended up with a recipe that yielded dry & crumbly or wet & sludgy mixtures that never baked well. The moment my dough hit the hot avocado oil I exclaimed, “It worked! It really worked!” I doubled the recipe to make two donuts, and it did just that. They smelled and tasted like the originals, and in my opinion the texture is actually a bit better. My oil was a little hot, so once my donuts were brown on both sides (6-8 minutes) and cooked on the outside, I air-fried them on 325 for 8 minutes just to make sure I didn’t undercook them. They were so bomb! I will be making these again and sharing with others.
