The little-black-dress of desserts

The coming of July means another birthday for me. That calls for chocolate cake!

This time I thought I would go simple, yet elegant, with moist chocolate layers, whipped cream and a finish of dark chocolate ganache. My inspiration was a classic whoopie pie only sans marshmallow cream. This decadent beauty uses stabilized whipped cream to firmly hold up to the chocolate layers. Black and white, classic, always a perfect choice.

Tuxedo Cake_1b I used my favorite go-to recipe for the cake layers. This One-Pan Double Chocolate Cake is just the perfect dark cocoa and moist cake goodness that I need. Who doesn’t love a cake that you can mix in just one pan? Less pans to wash means a happier birthday girl…

I want the layers to be held up by a thick layer of cream without collapsing and squirting out the sides. In order to do that, I switched from the original 8″ cake pans to 9″. This makes the layers thinner and spreads the weight out a bit. Remember to reduce the cooking time to 24-29 minutes or the layers will be over-cooked.

Tuxedo Cake_5b Tuxedo Cake_4sq This technique for stabilizing whipped cream is simple  but can be a bit tricky. You have to make sure you add the gelatin when it is not hot, but still liquid. If you allow it to set up, even a little, it will go into the cream as big clumps… yuck!

Tuxedo Cake_3 Totally worth it. This cake is my kind of heaven. Go ahead, take a bite… happy birthday to me!

    I made this cake for our families Valentines Day celebration. Not only was it easy to make, delicious and beautiful, it was voted as one of the best cakes EVER by my husband. Encorporating the gelatin into the whipped cream while it is warmed from the microwave is brilliant as it didn’t clump up like I have had happen in the past. Definitely a keeper!
