3-gal Schwarzbier-esque recipe?

For the longest time, my dad has described his favorite beer as "almost like drinking a piece of bread." He never could come up with the name though. He prefers darker, malty beers, so I brewed him a porter for Fathers Day. He likes it, but I want to nail down his favorite.

Earlier this week, I was drinking a Dortmunder from Berghoff and it jogged his memory. Dortmunder Union Dark, he said it looked and tasted like pumpernickel bread. After some research, I have found that Dortmunder Union Dark was a Schwarzbier.

Does anyone have a 3-gallon Schwarzbier recipe that I can use ale yeast with? I know that a Schwarzbier is usually made with lager yeast, but I don't have a fermentation chamber.

I have a schwarzbock that I make. I can't post the recipe until tomorrow.

Got home earlier tonight than expected.

For 5 gallons:

14lbs light Munich
8oz Crystal 20L
4oz Carafa II
4oz Carafa III
2oz Chocolate malt
2oz wheat malt

Decoction mash with rests at 122F and 151F

2oz Hallertauer for 60 minutes
1oz Spalter at 5 minutes

White Labs 833 German Bock Lager

Wlp036 is a good yeast to use in place of a lager strain. Just keep the initial fermentation temp lower. Between 65 and 68. It is a nice malt forward ale yeast.
