1/3 c. butter
4 eggs
1 c. flour
1 c. milk

Preheat oven to 425 degrees. Put butter in 8 inch round cake pan and place in oven while oven is heating.

In blender, put 4 eggs. Turn on and blend for 1 1/2 minutes. While still whirling, pour in flour and milk. Blend another 30 seconds to 1 minute longer.

Pour batter into pan in oven, pouring slowly so melted butter is not on top of batter. Bake 20 minutes. Serve hot with powdered sugar and lemon juice or maple syrup.
