Grand Marnier Chocolate Cake: Grand Marnier Day!

Tomorrow is Grand Marnier Day, so I thought you'd want to bake this Grand Marnier Chocolate Cake ahead. Grand Marnier is a remarkable combination of a premium blend of cognac and exotic oranges created in 1880 by Louis-Alexandre Marnier Lapostolle. Louis-Alexandre Marnier Lapostolle perfected the premium Grand Marnier blend in 1880 and at the time, his vision of combining the essence of wild tropical oranges from Haiti with premium cognac from France was seen as cutting edge and completely unexpected. The cognac found in Grand Marnier is made from Ugni Blanc grapes from five of the best crus within the Cognac region in France and is double-distilled in copper stills. The bitter, exotic orange called ‘Citrus Bigaradia’ sourced from the Caribbean, is a rare variety which offers an intense and unique flavor profile and aroma.
