Black and white chocolate cake is a rich, decadent chocolate layer cake with a center of chocolate ganache and creamy white chocolate frosting on top. Perfect for chocolate lovers!
Chocolate cake is one of my favorite desserts of all time. I mean really. On just about any occasion, nothing beats a slice of decadent chocolate cake. Celebrating? Eat cake! Sad your favorite TV show is ending? Eat cake. Craving something out of this world chocolatey just because it’s Friday? Eat this Black and White Chocolate Cake.
Apparently next Tuesday is National Chocolate Cake Day. Did you know that? I had no idea. Then it popped up in my Facebook feed. There are so many “national insert favorite food” days that I lose track. But when I saw that I thought to myself “This is perfect timing! I have the most insanely scrumptious chocolate cake to share on the blog and now there is a day dedicated to it. It’s fate!”
Ok maybe I didn’t think it was fate. But I did think it was the perfect time to share this recipe with you.
So I penciled it in my planner to share with you next week.
But, yeah… I’m not patient. And I really, really, really wanted to share this with you ASAP.
And besides, if I waited until National Chocolate Cake Day to share this recipe with you then you likely wouldn’t be able to make it on said cake day and therefore wouldn’t get to celebrate it.
And not celebrating a day that celebrates cake? Well, that is a travesty.
Not making this black and white chocolate cake is also a travesty.
So why not kill two birds with one stone and make this cake this weekend? That way you can celebrate National Chocolate Cake day all weekend long leading up to it. Because, in all actuality, there shouldn’t be just one day dedicated to the deliciousness that is chocolate cake.
And for more chocolate cake goodness, you can make my recipe for dark chocolate raspberry cupcakes, too!
