Step 1

Place butter in a 9x13-inch baking dish.  Set the baking dish in a cold oven, then turn the temperature up to 475 degrees F and let the oven preheat, heating the pan and melting the butter at the same time.  Check on the butter as it melts so it doesn't burn.

Step 2

Meanwhile, make the German pancake batter by adding eggs, milk, flour, sand salt to a blender and blend for 10-20 seconds until smooth.

Step 3

When the butter is melted, slide the pan out of the oven and pour the batter over the melted butter.

Step 4

Return the pan to the oven and bake for 14-15 minutes, until the German pancake has puffed up around the edges and is golden brown.

Step 5

Slice and serve immediately with syrup, fruit, or lemon juice and sugar.
