The Joneses' German Pancakes (Bruce Jackson)

One of my all time favorite recipes is my dad's German pancakes. The best part is you can use the same recipe for crepes too.  

Ingredients
      6 eggs
      1 c. milk
      1 c. flour
      1/2 c. sugar
      1 t. vanilla
      1/2 t. salt
      1 cube butter

Melt butter in an 11x13 in. pan in the oven at 400 degrees.  Put the eggs into blender and blend until bubbly.  Add remaining ingredients and blend until light and bubbly.  Remove the melted butter from oven and pour the egg mixture into pan on top of butter.  Bake in the oven for 10-15 min.  Cut into squares and serve with powdered sugar, syrup, or jam.  For crepes: No butter and decrease ingredients' amounts.
