Puffy German Pancakes

This is a recipe I grew up with. It's one of the easiest breakfasts! The best part is that you blend everything and just dump it in a pan, so there's no hassle of flipping individual pancakes. You just bake, cut and serve.

Preheat oven to 400
Put 2 tablespoons of butter in a 9 x 13 baking pan and put it in the oven

In a blender put:
4 eggs
2/3 cup flour
1 tablespoon sugar
1/2 teaspoon salt (i use kosher)
2/3 cup milk
Blend and pour over the melted butter in the 9 x 13

Bake at 400 for 10 minutes
Then turn down the oven to 350 and bake for about 15 more minutes. Check it periodically. You want the sides to be puffy and the center to be firm. That's how you'll know it's done.
