This is a recipe for scrumptious keto blueberry donuts that uses gluten-free almond and coconut flours! They can be baked using fresh or frozen berries.
Mix together almond flour, coconut flour, baking powder, xanthan gum, salt, nutmeg and erythritol in large bowl. Blend in the butter until coarse crumbs.
Place blueberries in a small microwaveable bowl and microwave about 30 seconds or until they pop. Stir in the stevia, almond milk, and egg. Add this to the flour mixture and mix just until combined.
Place the batter in a plastic bag with corner snipped off or a pastry bag. Pipe batter into well greased donut pan molds (or use silicone molds for easy release).
Bake at 350 °F for 10-12 minutes. Cool donuts on a wire rack for 10 minutes, then remove from pan onto cooling racks.
For glaze, add lemon juice to powdered sweetener until desired consistency is reached. To add color, microwave blueberries and add to glaze. Dip donut tops into glaze and let sit to dry.

Notes
Coconut flour can vary in absorbency. It's best to start with half and add more if needed. If the batter is too thick, more almond milk can be added.If you don't have cooling racks, use parchment paper. The parchment paper can help your donuts cool on the counter.Use a piping bag for the glaze. If you don't like dipping the donuts, a piping bag can work perfectly too.
