Chocolate Cake with Whipped Cream Frosting
This Chocolate Cake with Whipped Cream Frosting is a delicious, moist cake–made with a fluffy light frosting using heavy whipping cream. This chocolate cake recipe has been in our family for years. The cake is awesome–full and rich. And the frosting is light and fluffy. It’s truly a wonderful “anytime” dessert that turns out perfect every time! Classic chocolate frosting also works well, if you prefer to frost the cake with a stiffer, more robust frosting.

Oh, I love a good chocolate cake. So let’s get to the recipe right away. This cake is simple, not too sweet, and simply delightful for any occasion. I can list the holidays it’s good for (all of them), but sometimes you just need a cake to make for a weeknight treat.
Sometimes the best meals are ones that are simple, but even if it’s just for chips and beer, or dessert (cake) and coffee, or a potluck where everyone brings a dish, the point is fellowship.
What is the most popular chocolate cake in the world?
The “Sachertorte” cake is the most popular. It’s a Viennese cake that has been around since 1832, consisting of 3 layers of chocolate sponge cake and a thickly spread apricot jam in between. The jam also covers the top. I first had a slice of sachertorte when I was in New Orleans with my Aunt Ellen. I thought I had died and gone to heaven. It’s truly lovely (melts in your mouth).

What makes a cake moist and fluffy?
What makes this chocolate cake so moist? It’s the sour cream (and boiling water) that really adds the moisture. Our most popular recipe on our site is Sour Cream Banana Bread. You can read all the comments how everyone loves that recipe (yes – sour cream!)

Tips and substitutions to try:
- Eggs: Bring the eggs to room temperature before using them. Simply set them out 30 minutes to an hour before you intend to start baking.
- Butter: make sure the butter is softened before you start the baking process.
- Chocolate: you can swap out the chocolate for your favorite brand or intensity. We always use “unsweetened chocolate.”
- Make ahead: You can make the cake ahead; frost right before serving.
- The frosting is light – so you need to dive into the cake and enjoy right away!
- Bake and freeze: Bake the cake ahead and freeze up to 30 days (well sealed so no air gets to it). Defrost the cake and frost it when ready to serve.
- Refrigerate any leftovers because of the “whipped cream” frosting.

Notes

Hi, how much is 3 squares exactly? I imagine 3 small squares from a a slab but that sounds too little.
I think I baked this cake once before and must have taken a chance without receiving a reply. But I can’t remember and want to bake the cake again.
Looks perfect! Happy New Year!
