Ingredients Method Notes

Ingredients
  

  • Donuts
  • 1 1/2 cups fine blanched almond flour
  • 1/4 cup granulated keto-friendly sweetener
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 2 large eggs
  • 3 tablespoons unsalted butter melted and slightly cooled
  • 1/4 cup unsweetened almond milk
  • 1 teaspoon vanilla extract
  • Cinnamon Coating
  • 2 tablespoons unsalted butter melted
  • 1/4 cup granulated keto-friendly sweetener
  • 1 1/2 teaspoons ground cinnamon

Method
 

  1. Preheat the air fryer to 320°F for approximately 3 minutes.
  2. Whisk the almond flour, sweetener, baking powder, cinnamon, and salt together in a medium mixing bowl.
  3. In a separate bowl, whisk together the eggs, melted butter, almond milk, and vanilla.
  4. Pour the wet mixture into the dry ingredients and stir until a smooth batter forms.
  5. Let the batter rest for 2 to 3 minutes.
  6. Lightly grease silicone donut molds if necessary.
  7. Transfer the batter to a piping bag or zip-top bag with one corner snipped off.
  8. Pipe the batter into the donut cavities, filling them approximately three-quarters full.
  9. Place the mold inside the air fryer basket.
  10. Air fry at 320°F for approximately 8 to 10 minutes, or until the tops are set and a toothpick inserted into the center comes out mostly clean.
  11. Allow the donuts to cool in the mold for approximately 5 minutes.
  12. Carefully remove the donuts and place them on a cooling rack.
  13. Combine the cinnamon and granulated sweetener in a shallow bowl.
  14. Brush each donut lightly with melted butter.
  15. Dip or roll each donut in the cinnamon mixture until evenly coated.
  16. Serve slightly warm.

Notes

Notes

Air fryers vary: Begin checking the donuts around the 8-minute mark. Smaller or more powerful air fryers may cook them faster.
Use fine blanched almond flour: Almond meal can make the donuts heavier and more grainy.
Measure carefully: Too much almond flour can make keto donuts dry. For the most consistent results, weigh the flour with a digital kitchen scale or lightly spoon it into the measuring cup without packing it down.
Don't remove them immediately: Let the donuts rest in the mold for about 5 minutes after cooking. Almond flour baked goods are delicate while hot and become firmer as they cool.
Sweetener matters: A granulated monk fruit, erythritol, or allulose blend works well. Allulose may brown more quickly, so watch the donuts closely.
For the best cinnamon coating: Brush the donuts with melted butter while they're still slightly warm, then dip them into the cinnamon sweetener.
Storage: Keep cooled donuts in an airtight container for 1 to 2 days at room temperature or refrigerate for up to 5 days.
Freezing: Freeze uncoated donuts for up to approximately 2 months. Thaw, warm briefly, then add the butter and cinnamon coating before serving.
Nutrition: Macros are estimates and will vary depending on the specific brands of almond flour, sweetener, almond milk, and other ingredients used.
