Combine almond or cashew flour, coconut flour, salt, and baking soda in a medium size bowl and whisk until well combined.
Add eggs to a small bowl and beat lightly. Add syrup or honey, coconut oil, coconut milk, and vanilla to eggs and mix well.
Add the dry ingredients to the egg mixture and mix until combined.
Pour or pipe the batter into your prepared silicone donut mold and bake for about 20 minutes until the top is golden brown and a toothpick inserted into the cake comes out clean.
Whip all the ingredients in a food processor, blender or immersion blender until very smooth and creamy. Add 1-2 tsp blue spirulina to achieve desired color. Pour frosting into a shallow bowl and dip each cooled donut into icing. Sprinkle with dye-free sprinkles if using and enjoy!
