This Tuxedo Chocolate Mousse Cake, usually $15.99 at Costco, is $2.00 off by coupon this month. The taste is rich and moist, chocolate and wonderful. Bottom layer is what I think is the typical Costco chocolate cake, then a thin vanilla butter cream layer, a thick layer of chocolate mouse, and then a final layer of chocolate cake. Icing is dark chocolate with white chocolate accents.
I took this to my friend Rose's birthday party in January, and everyone seemed in favor. The cake can serve a large gathering as it's very, very, very rich. The slice in the picture was larger than I could finish. Other guests had the same problem; I would recommend very thin slices.
It is possible to cut fairly thin slices using dental floss. I recommend doing this cutting out of sight, as dental floss puts some people off. If you've never cut a cake with dental floss, you can YouTube the directions.
I've mentioned before I don't care for sweets so I don't think I'll be purchasing this again, but it's lovely if you like sweets, and for a Valentine's Day celebration, it's going to be perfect.
