Preheat your waffle iron.
In a large bowl, whisk together the buttermilk, whole milk, melted coconut oil, eggs, vanilla extract and juice from 1 Meyer lemon. Set aside.
In another bowl, whisk together the flours, corn starch, baking powder, brown sugar, salt, and zest from 1 Meyer lemon.
Add the dry ingredients to the wet and fold the ingredients together until just moistened. Fold in the blueberries.
Grease your waffle iron, and add about 1/2 cup to 2/3 cup of the waffle batter depending on the size of your iron. Cook until done and then repeat for the rest of your batter. Don't forget to grease your waffle iron each time you make a waffle.
Garnish the waffles with thawed blueberries, maple syrup and confectioner's sugar.
Enjoy!
