Combine wet ingredients in another bowl, mix well, and then slowly add dry ingredients in. It will be REALLY sticky and thick!
Spoon about a large tbsp. full of batter on to a WELL sprayed cookie sheet. If you want the traditional look you can use a piece of parchment paper and create a long roll of dough, roll it up and put it in the fridge, then cut when dough is harder to make slices. (I don't bother with that)
Bake at 400 degrees for about 12 minutes or until the outer edges are firmer but the very middle is still a bit undercooked. This will create a really chewy german spice cookie.
If you want a glaze on your lebkuchen, heat on the stovetop sugar, powdered sugar and enough water to make the consistency you want. Thin is okay, it will still create a sweet glaze on top.
Put cookies on parchment paper or a cooling rack with paper underneath and spoon glaze on so it won't stick to plate.
