Preheat oven to 375 degrees F.
Mini German Pancakes are made in a regular size muffin tin. Begin by adding a thin slice of butter to the center of each muffin tin.
Place the cupcake pan in the oven, just for a few seconds, to melt the butter.
In a blender add eggs, milk, flour, salt and vanilla. Blend until smooth.
Pour batter into muffin tin, filling each spot about 2/3 full.
Bake for 10-12 minutes or until puffy and edges are golden brown. Remove from oven and allow to cool for a few minutes.
