So, my first thought is that I may have added a bit too much bourbon for it to be a spot-on clone. However, I'm not going to complain. Due to my grain limitations, I had to adjust the recipe as follows:
American Munich 1.50 lb, Grain, Mashed
American chocolate malt 0.67 lb, Grain, Mashed
American two-row 10.00 lb, Grain, Mashed
American wheat 0.25 lb, Grain, Mashed
Crystal 120L 0.50 lb, Grain, Mashed
Crystal 80L 0.50 lb, Grain, Mashed
Flaked oats 0.50 lb, Adjunct, Mashed
Light D.M.E. 3.00 lb, Extract, Extract
Columbus 0.75 oz, Pellet, 60 minutes
Willamette 0.50 oz, Pellet, 10 minutes
I mashed at 154 and ended up with an OG of 1.095 and an FG of 1.020. I think the mouthfeel and sweetness levels are quite good so I wouldn't consider adding lactose. The color and aroma are remarkably close and the flavor profile is very similar. I used McAfee's Benchmark Old No.8 instead of Maker's since it's an awesomely good bourbon for the money, but I probably shouldn't have added the bourbon that I soaked the oak chips in and some additional bourbon at bottling.
All in all, the process created a delicious beer, gave me a great learning experience, and landed me a bundle of beer for a lot less than $3.50 per bottle.
