Homemade German Spaetzle - The Wanderlust Kitchen Place your spaetzle maker over the top, then pour half of the batter into the cup of the device. Quickly slide the cup back and forth to allow the batter to drop through. Repeat with second half of batter, working quickly, until all the batter is cooking in the pot. Set the spaetzle maker aside and give the dumplings a good stir in the pot.
