Combine all ingredients in a large bowl using an electric mixer.
Fill a pot with water and bring to a boil. Using a spaetzle maker, a potato ricer, a colander, or anything with a hole in it, press the dough through and let it drop into the boiling water. Let it boil for 6 minutes. The cooked spaetzle will rise to the top and float. (If you are having a hard time pressing the dough through the holes, you can thin the dough out more by adding a little extra milk) Use a strainer or slotted spoon to fish out the cooked spaetzle.
I like to saute the cooked spaetzle in a pan with butter before serving. Be sure to season with salt and pepper to taste.
