In a bowl, combine flours, brown sugar, baking powder, and salt. Set aside.
In blender, process buttermilk, banana, vanilla, egg, and oil until smooth. Pour into dry ingredients. Lightly stir, just until combined – do not over beat it!
Lightly oil your griddle or frying pan, preheat over medium or medium-low heat. Scoop 1/4 cup(50 ml) amounts of batter onto the griddle. Gently spread batter out into a larger circle, about 4 – 4.5″ in diameter.
Cook until bubbles start popping through top surface. Flip, cook until done.
Serve with blueberry syrup… maybe with whipped cream, and a sprinkling of nutmeg!
*If not buttermilk, use 1 1/2 cups milk (or a dairy free version), with 1 tbsp lemon juice mixed in. Allow to sit for 5 minutes before using.
