• Preheat the oven to 350°F (180°C). Grease a 6-hole donut pan with coconut oil. Set aside.
• In a large mixing bowl, add all-purpose flour, blueberries, and baking powder. Stir.
• Add maple syrup, oil, vanilla extract, and almond milk, and stir to form a smooth batter.
• Use a spoon or piping bag to fill the donut pan. Fill each hole with the batter up to 3/4 of their level.
• Bake the donuts at 350°F (180°C) for 12-14 minutes until they are golden brown and a pick inserted in the center comes out clean.
• Set aside on a cooling rack at room temperature and wait until cold before glazing.

Glaze

• When the donuts have reached room temperature, prepare the glazing.
• In a small mixing bowl, combine icing sugar and almond milk and add a pinch of blue spirulina if you want to add a blue color to your donuts.
• Dip the top of the donuts into the glazing and hold it for a few seconds above the bowl to let the excess glazing drip out.
• Place the donuts back onto the cooling rack and repeat until all donuts are glazed.
• Finally, pop the donuts in the fridge for 30 minutes to harden the glazing.
