Preheat the oven to 350ºF. Grease a donut pan and set aside.
In the order listed, add all ingredients to a blender (minus the blueberries and glaze ingredients) and blend on high until smooth. The mixture will be thick!
Add your blueberries into the blender and fold into the batter with a spatula.
Spoon the batter into the prepared donut pan, filling each all the way to the top. Bake for 16 - 18 minutes until the donuts are springy to the touch. Remove from the oven and let cool in the pan for at least 15 minutes.
Once cooled, flip the donuts out onto a wire rack and cool completely.
If you want to make the glaze, whisk together the powdered sugar, lemon juice and 2 teaspoons almond milk. Add additional almond milk until glaze can be drizzled over donuts. Drizzle on top of each donut and enjoy immediately. Donuts can be stored at room temperature in an airtight container for 2 days.
