Why You’ll Love Moist Chocolate Cake Recipe

I love how moist and tender this chocolate cake turns out, especially with the hot brewed coffee helping deepen the chocolate flavor. I also like that the frosting is creamy, smooth, and rich without being too complicated. Since I bake it in a 9×13-inch pan, I find it easy to slice, serve, and decorate any way I like.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

For the cake:

1 ½ cups (285g) granulated sugar
½ cup (118 ml) vegetable oil
3 large eggs, at room temperature
1 tablespoon (15 ml) pure vanilla extract
½ cup (118 ml) sour cream, at room temperature
2 cups (280g) all-purpose flour, sifted
½ cup (40 g) cocoa powder, sifted
1 tablespoon (5g) espresso powder (optional)
2 ½ teaspoons (9 g) baking powder
½ teaspoon (2 g) baking soda
1 teaspoon (5 g) salt
1 ¼ cup (296 ml) hot brewed coffee

For the frosting:
½ cup (113g) unsalted butter, cold

6 ounces (170g) full-fat cream cheese, cold
½ cup (40 g) cocoa powder, sifted
3– 4 (390-520 g) powdered sugar, sifted (see notes)
2 tablespoons (30ml) milk or heavy whipping cream
1 tablespoon (15ml) pure vanilla extract

Directions

For the cake, I preheat the oven to 350°F and spray a 9×13-inch pan with cooking spray.

In a large mixing bowl, I combine the sugar, vegetable oil, eggs, and vanilla extract. I beat everything on medium speed until the eggs and oil are well incorporated and the batter looks lighter in color. Then I mix in the sour cream and beat until well combined.

In a separate bowl, I sift together the flour, cocoa powder, espresso powder, baking powder, baking soda, and salt. I add half of the dry ingredients to the wet ingredients, followed by half of the hot brewed coffee, and mix on low speed just until the flour is incorporated. Then I add the remaining dry ingredients and coffee and beat until everything is well combined. I scrape down the sides of the bowl and stir from the bottom up to make sure the batter is evenly mixed.

I pour the batter into the prepared pan and bake at 350°F for 26–28 minutes. I test the cake by inserting a toothpick into the center. When it comes out clean, I remove the cake from the oven and let it cool completely.

For the frosting, I cut the cold butter into 1-inch blocks and beat it for 3–4 minutes until softened. I add the cold cream cheese and beat for 2–3 minutes until the mixture is fluffy and smooth, scraping down the bowl as needed.

I add the cocoa powder and vanilla extract and beat until well combined. Then I add the powdered sugar 2 cups at a time, followed by one tablespoon of milk or heavy whipping cream, and beat for 60–90 seconds until smooth. I add the remaining powdered sugar and cream as needed, then beat for at least 2 minutes until the frosting reaches the consistency I like.

I spread the frosting over the completely cooled cake and decorate it with sprinkles.

Servings and Timing

This recipe makes 12–15 slices.

Prep Time: 20 minutes
Cook Time: 26 minutes
Total Time: 46 minutes

Variations

I sometimes skip the espresso powder when I want a more classic chocolate flavor. I also like adding chocolate chips to the batter for extra richness. For a more festive cake, I change the sprinkles to match the occasion. I can also use heavy whipping cream in the frosting when I want a richer, creamier finish.

Storage/Reheating

I store this cake covered in the refrigerator because of the cream cheese frosting. It keeps well for about 4–5 days. Before serving, I like to let slices sit at room temperature for 20–30 minutes so the cake and frosting soften.

I do not usually reheat this cake because the frosting is best kept cool or at room temperature. If I want a slightly softer slice, I let it rest on the counter instead of microwaving it.

FAQs

Can I make this chocolate cake ahead of time?

Yes, I like making the cake a day ahead because the flavor stays rich and the texture remains moist.

I use hot brewed coffee because it deepens the chocolate flavor, but the cake does not taste strongly like coffee.

Can I skip the espresso powder?

Yes, I can skip the espresso powder since it is optional.

Why does the cake need sour cream?

I use sour cream because it adds moisture and helps create a soft, tender crumb.

Can I use a different pan size?

I prefer a 9×13-inch pan for this recipe, but other pan sizes may change the baking time.

How do I know when the cake is done?

I insert a toothpick into the center, and when it comes out clean, the cake is done.

Should the cake be cooled before frosting?

Yes, I always let the cake cool completely so the frosting does not melt.

Can I make the frosting thicker?

Yes, I add more powdered sugar until the frosting reaches the thickness I like.

Can I make the frosting softer?

Conclusion

This moist chocolate cake is rich, fluffy, and easy to make in a simple 9×13-inch pan. I love the deep chocolate flavor, the tender crumb, and the creamy chocolate cream cheese frosting on top.
