Description
An old-fashioned sour cream chocolate cake recipe that’s deeply chocolatey, ultra-moist, and simple enough for beginners. The secret ingredient—sour cream—creates an impossibly tender crumb that stays soft for days. Perfect for birthdays, potlucks, or anytime you need a comforting homemade dessert.
Ingredients
For the Cake:
- 2 cups all-purpose flour
- ¾ cup unsweetened cocoa powder (Dutch-process or natural both work)
- 1½ teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 cups granulated sugar
- 3 large eggs, room temperature (this helps everything mix smoothly)
- 1 cup full-fat sour cream (don’t skimp—this is what makes it moist!)
- ½ cup neutral oil (vegetable or canola)
- 2 teaspoons vanilla extract
- 1 cup hot coffee or hot water (coffee deepens the chocolate without tasting like coffee)
Optional Frosting:
- ½ cup (1 stick) butter, softened
- 3 cups powdered sugar
- ½ cup cocoa powder
- ¼ cup sour cream or heavy cream
- 1 teaspoon vanilla extract
Optional Add-ins or Toppings:
- ½ cup mini chocolate chips
- Powdered sugar for dusting
- Fresh berries (raspberries or strawberries are beautiful!)
Instructions
Preheat your oven to 350°F (175°C). Grease your cake pan generously with butter or non-stick spray, then line the bottom with parchment paper.
In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and sugar until everything is evenly distributed.
In a separate bowl, whisk together the eggs, sour cream, oil, and vanilla extract until the mixture is smooth and creamy.
Slowly stir the hot coffee (or hot water) into your wet ingredients.
Pour the wet ingredients into the dry ingredients and gently mix just until combined.
Pour the batter into your prepared pan. It will be quite liquid, so pour carefully. Bake for 30–40 minutes (30 minutes for round pans, closer to 40 for a 9×13). The cake is done when a toothpick inserted in the center comes out with just a few moist crumbs.
Let the cake cool in the pan for about 15 minutes, then turn it out onto a cooling rack. This is important—frosting a warm cake will melt into a puddle!
If you’re making the frosting, beat the softened butter until fluffy, then gradually add powdered sugar, cocoa powder, sour cream, and vanilla.
Notes
- Don’t overbake – Pull the cake when a toothpick has a few moist crumbs clinging to it; it will continue cooking as it cools
- Sift your cocoa powder if it’s lumpy – This prevents dark specks and ensures even chocolate distribution
- Line your pan with parchment – Even in a non-stick pan, parchment guarantees easy release
- Let the cake cool completely before frosting – Warm cake + frosting = melted mess
- For extra-moist cake – Brush the layers with simple syrup (equal parts sugar and water, heated until dissolved) before frosting
