Chocolate Bundt Cake

A super chocolate cake, fluffy and tender and not at all dry. A bit unusual in that it cooks at a very low temperature (275F) for a long time.

• My 2-qt bundt pan, although not as fancy as the one shown, worked fine. (The recipe can't decide if a 2-qt or a 2-1/2-qt one is needed.)
• I used a proper double boiler rather than the improvised one suggested.
• I used Kahlua instead of brandy.
• The cake was not done in the 1h15 advised; I probably did another 20min altogether. Really nice.
