Ingredients
  

  • 1 cup fine almond flour (blanched for best texture)
  • 1/3 cup vanilla protein powder (whey or plant-based; see FAQs)
  • 1 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp fine sea salt
  • 1/3–1/2 cup granulated erythritol or allulose (to taste)
  • 2 large eggs, room temperature
  • 1/2 cup unsweetened almond milk (or other low carb milk)
  • 2 tbsp Greek yogurt or coconut yogurt
  • 2 tbsp melted coconut oil or unsalted butter, slightly cooled
  • 1 tsp vanilla extract
  • 1/2 cup blueberries (fresh or frozen; if large, halve them)
  • Optional glaze: 1/2 cup powdered erythritol or allulose, 1–2 tbsp almond milk, 1/4 tsp vanilla
  • Optional add-on: zest of 1/2 lemon for brightness

Method
 

  1. Prep the pan and oven: Preheat to 350°F (175°C). Lightly grease a 6-cavity donut pan or spray with oil. If using silicone, place it on a sheet pan for stability.
  2. Mix dry ingredients: In a medium bowl, whisk almond flour, protein powder, baking powder, baking soda, salt, and sweetener until evenly combined and lump-free.
  3. Whisk wet ingredients: In another bowl, whisk eggs, almond milk, yogurt, melted coconut oil, and vanilla. Add lemon zest if using.
  4. Combine: Pour wet into dry and stir with a spatula until just combined. The batter should be thick but scoopable. If it’s too thick, add 1–2 teaspoons more almond milk.
  5. Fold in blueberries: Gently fold in blueberries so they don’t bleed too much into the batter. Avoid overmixing.
  6. Fill the pan: Spoon or pipe batter into the donut cavities, filling each about 3/4 full. Smooth tops lightly.
  7. Bake: Bake for 12–14 minutes, until the tops are set and a toothpick comes out mostly clean with a few moist crumbs. Do not overbake.
  8. Cool: Let donuts cool in the pan for 5 minutes, then transfer to a rack to cool completely. They firm up as they cool.
  9. Glaze (optional): Stir powdered sweetener with almond milk and vanilla to a pourable consistency. Dip cooled donuts or drizzle over the top. Let set 10 minutes.
