Preheat oven to 450F and place an oven safe pan in the oven. (We like to use a cast iron pan)
In a blender; add eggs, flour, milk, vanilla, sugar, salt, melted butter, and lemon zest. Blend until smooth.
Carefully remove the hot pan from the oven and drop in 2 tbs of butter and 1 cup of blueberries. Pour in the batter and return the pan to the hot oven for 15-17 minutes
Remove, top with powdered sugar and maple syrup. It will puff up while cooking and deflate as it cools.
Enjoy!
