Pre-heat oven to 350ºF.
Line a standard 12-cup muffin pan with paper liners.
Blend the wet ingredients in a blender until smooth.
Sift the dry ingredients together (I use a medium kitchen sieve).
Combine dry ingredients with the wet just until no dry spots remain, don't overmix.
Optional: toss the blueberries with 1 tablespoon of einkorn flour.
Fold the blueberries into the batter; scoop the batter into the cups filling them to the top.
Bake einkorn blueberry muffins for 35 minutes, or until the tops brown slightly.
