Made this tonight, and had to sub toasted almonds and coffee (for the rum). Excellent!
I cut the brown-sugar measurement by half, and (at least to me and J.) it's subtly sweet. I also threw in some quatre-epices and cardamom. Next time, I might add rum-soaked raisins.
Update: But because I baked it in a Bundt pan for the whole 55 minutes, it's dry. smileys/frown.gif Caveat Bundt bakers! I should've pulled it at 35 or 40 minutes.
