This Sour Cream Chocolate Cake is rich, moist, and topped with a smooth chocolate frosting that makes every bite indulgent. It's a classic chocolate cake with a little tang that keeps the crumb tender and flavorful.
I often make this for birthdays of family gatherings, and it's one of those recipes that reminds me of the chocolate cakes my grandmother used to make when I was a girl. If you've tried my Chocolate Mayonnaise Cake before, this one will feel just as decadent.

Key Ingredients for Sour Cream Chocolate Cake
See the recipe card below for a full list of ingredients and instructions.
- Devil's food cake mix: a shortcut base that gives the cake structure and flavor.
- Sour cream: adds moisture and a slight tang for a tender crumb.
- Cocoa powder: deepens the chocolate flavor.
- Butter: creates a rich, creamy chocolate frosting.
Ingredient Substitutions
- Greek yogurt can be used instead of sour cream, or use my homemade sour cream.
- Vegetable oil works just as well as canola oil.
- Almond milk can be used in place of regular milk for the frosting.
Sour Cream Chocolate Cake Variations
- Layered delight: add a layer of raspberry jam between cake layers before frosting.
- Bundt style: bake the batter in a Bundt pan and drizzle with glaze instead of frosting.
- Nutty crunch: fold in chopped walnuts or pecans for texture.
Tips for the Best Chocolate Frosting
- Sift the cocoa powder and powdered sugar to avoid lumps.
- Beat the frosting on medium-high speed to get a light and fluffy texture.
- Add milk gradually so the frosting spreads smoothly without becoming too thin.
How to Store
Store the frosted cake in an airtight container at room temperature for up to 3 days or refrigerate for 5 days. To serve, let slices sit at room temperature for about 20 minutes so the frosting softens.
Serve with Sour Cream Chocolate Cake
This sour cream chocolate cake pairs beautifully with a scoop of vanilla ice cream or rhubarb cookies and cream ice cream. It also goes great with a glass of milk, or a hot cup of strong coffee.
