Warm waffle iron.
Melt butter on low in a pan on the stove while you prep other ingredients.
NOTE: If using whole grain Einkorn (see notes below), grind the grain into flour in Vitamix or grain mill. I use my Vitamix and start on 1 and slowly increase to 10 for a total of about 1 minute. That's it! You have flour.
Combine flour, baking powder and salt in a large bowl. Stir with a whisk to combine.
In a 4 cup measuring cup or medium sized bowl, combine milk, eggs, honey, and vanilla. Mix well.
Add liquid ingredients (milk, eggs, honey and vanilla) to dry ingredients and mix just until blended. Fold in butter just until mixed, and then add blueberries. Do not overmix.
Add waffle mix to preheated waffle iron per manufacturers instructions. I use 1/3 cup of batter with my waffle iron and it is the perfect amount. Top with grass fed butter (like Kerrygold), fresh berries and maple syrup.
