Prep & Cook Time

Prep Time: 10 minutes
Cook Time: 16 minutes
Total Time: 26 minutes (plus cooling time)
Servings: 36

Ingredients

15.25 ounce box chocolate cake mix (I use Betty Crocker Chocolate Fudge)
1/2 cup unsweetened cocoa powder
1/2 cup granulated sugar
3.4 ounce box instant chocolate pudding
1 1/4 cups freshly brewed coffee
3/4 cup vegetable oil
4 large eggs
1 cup full-fat sour cream
1 teaspoon vanilla extract

Instructions

Preheat your oven to 350°F (175°C). Prepare your baking pans by greasing and flouring, or lining with parchment paper. You can use two 9-inch round pans, a 9×13-inch pan, or standard cupcake tins.
In a large mixing bowl, whisk together the dry ingredients: the chocolate cake mix, unsweetened cocoa powder, granulated sugar, and the instant chocolate pudding mix.
In a separate bowl, combine the wet ingredients: the freshly brewed coffee, vegetable oil, eggs, sour cream, and vanilla extract. Whisk until smooth and fully combined.
Pour the batter evenly into your prepared pans. Bake immediately. For two 9-inch rounds or a 9×13-inch sheet cake, bake for 30-35 minutes. For cupcakes, bake for 15-18 minutes. The cake is done when a toothpick inserted into the center comes out with a few moist crumbs attached.
Let the cakes cool in their pans for 10-15 minutes before turning them out onto a wire rack to cool completely before frosting.

Variations

Cupcakes: This batter is perfect for cupcakes. Fill liners 2/3 full and adjust the bake time as directed.
Layer Cake: Bake in three 8-inch pans for 20-25 minutes to create a stunning, tall layer cake.
Bundt Cake: Grease a bundt pan very thoroughly and bake for 40-50 minutes for an elegant presentation.
Trifle or Cake Pops: Bake the cake in a 9×13 pan and use the cooled cake cubes for a rich trifle or as the base for cake pops.

Tips for Success

For the best texture, use room temperature eggs and sour cream. They incorporate more evenly into the batter.
The coffee is essential for deepening the chocolate flavor, not for making it taste like coffee. You can use hot water, but the flavor won’t be as rich.
For the flattest cake layers ideal for stacking, wrap the warm cake pans with damp towel strips to help them cool evenly.

Storage & Reheating

Store the cooled, unfrosted cake tightly wrapped in plastic wrap at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, wrap it well and freeze for up to 3 months. Thaw overnight in the refrigerator. Slices can be reheated in the microwave for 10-15 seconds for a warm, gooey treat.

FAQ

Can I use a different flavor of cake mix?

Yes, you can use a devil’s food or dark chocolate cake mix. The added cocoa and pudding will still enhance it, but the flavor profile may vary slightly.

Can I make this without coffee?

Yes, you can substitute the coffee with an equal amount of hot water. However, the coffee intensifies the chocolate flavor without adding a coffee taste, so it’s highly recommended.

Can I use low-fat sour cream?

Full-fat sour cream is recommended for maximum moisture and richness. Using a low-fat version may result in a slightly less tender crumb.

Why do I need to add both sugar and pudding mix?

The extra granulated sugar sweetens the added cocoa powder, while the instant pudding mix adds structure and contributes to an exceptionally moist, dense texture.

My cake mix box is a different size (like 16.25 oz). Will that work?

Yes, a slightly different size (15.25 oz to 16.25 oz) will work fine in this forgiving recipe. No other adjustments are needed.

Can I make this in advance?

Absolutely. Bake the cake layers, let them cool completely, wrap them tightly in plastic wrap, and freeze for up to a month. Thaw in the refrigerator before frosting.
