Equipment You’ll Need

• 9×13 inch baking pan
• Medium saucepan
• Large mixing bowl
• Whisk
• Rubber spatula
• Measuring cups and spoons

Ingredients

• For the Cake:
• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 cup (2 sticks) unsalted butter
• 3 tablespoons unsweetened cocoa powder
• 1 cup Coca-Cola (classic, full-sugar)
• 1/2 cup buttermilk, at room temperature
• 2 large eggs, lightly beaten, at room temperature
• 1 teaspoon baking soda
• 1 teaspoon vanilla extract
• 1 1/2 cups miniature marshmallows
• For the Frosting:
• 1/2 cup (1 stick) unsalted butter
• 3 tablespoons unsweetened cocoa powder
• 6 tablespoons Coca-Cola (classic, full-sugar)
• 1 (16-ounce) box powdered sugar, sifted
• 1 teaspoon vanilla extract
• 1 cup chopped pecans

Instructions

1. Step 1: Preheat Oven and Prepare Pan. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
2. Step 2: Combine Dry Ingredients. In a large mixing bowl, whisk together the all-purpose flour and granulated sugar. Set aside.
3. Step 3: Heat Liquid Ingredients. In a medium saucepan over medium heat, combine the 1 cup of butter, 3 tablespoons of cocoa powder, and 1 cup of Coca-Cola. Bring the mixture to a boil, stirring occasionally. Once boiling, remove from the heat.
4. Step 4: Combine Wet and Dry. Carefully pour the hot Coca-Cola mixture over the flour and sugar mixture in the large bowl. Whisk until just combined and smooth.
5. Step 5: Add Remaining Cake Ingredients. In a small bowl, whisk together the buttermilk, eggs, baking soda, and vanilla extract. Pour this into the chocolate batter and whisk until everything is well incorporated. Be careful not to overmix.
6. Step 6: Fold in Marshmallows. Gently fold the miniature marshmallows into the cake batter using a rubber spatula.
7. Step 7: Bake the Cake. Pour the batter into your prepared 9×13 inch pan and spread evenly. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs attached (not wet batter).
8. Step 8: Prepare the Frosting. About 10 minutes before the cake is done baking, begin making the frosting. In the same saucepan (no need to wash), combine the 1/2 cup of butter, 3 tablespoons of cocoa powder, and 6 tablespoons of Coca-Cola. Bring to a boil over medium heat.
9. Step 9: Finish the Frosting. Once boiling, remove the saucepan from the heat. Whisk in the sifted powdered sugar until smooth, then stir in the vanilla extract and chopped pecans.
10. Step 10: Frost the Cake. As soon as the cake comes out of the oven, immediately pour the warm frosting over the hot cake. Use a spatula to gently spread it evenly to the edges. The heat from the cake will help the frosting set into a perfect, glossy glaze.
11. Step 11: Cool and Serve. Let the cake cool completely in the pan on a wire rack before cutting and serving. This allows the frosting to set properly.

Expert Cooking Tips

• Use Room Temperature Ingredients: For a smoother, more uniform batter, ensure your buttermilk and eggs are at room temperature before mixing.
• Don’t Use Diet Soda: The recipe’s flavor and chemical balance rely on classic, full-sugar Coca-Cola. Diet or zero-sugar versions will not produce the same rich result.
• Frost While Warm: The magic of this cake is pouring the warm, liquid frosting over the hot cake. The cake absorbs some of the frosting, making it extra moist, while the rest sets into a thin, fudgy layer on top.
• Sift the Powdered Sugar: For a perfectly smooth, lump-free frosting, always sift your powdered sugar before adding it to the hot liquid.

Substitutions and Variations

For buttermilk, you can make a substitute by adding 1/2 tablespoon of lemon juice or white vinegar to 1/2 cup of regular milk and letting it sit for 5 minutes. Walnuts can be used in place of pecans, or the nuts can be omitted entirely for a nut-free version. If you don’t have miniature marshmallows, you can omit them; the cake will still be delicious, just slightly less dense and moist.

Common Mistakes to Avoid

A common mistake is overbaking the cake. This is a very moist cake, so you should remove it from the oven when a toothpick test reveals moist crumbs, not when it’s completely dry. Another error is letting the cake cool before frosting. The ‘pourable’ frosting is designed to be applied to a hot cake, which is a key step to achieving the signature texture and glaze.

Serving Suggestions

This Coca-Cola cake is fantastic on its own, but for a truly decadent experience, serve a warm slice with a generous scoop of vanilla bean ice cream. The contrast of the warm, rich cake and the cold, creamy ice cream is heavenly. It also pairs wonderfully with a simple dollop of fresh whipped cream or a tall glass of cold milk.

Storage and Reheating Tips

Store the cake tightly covered with plastic wrap or in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate it for up to a week. The cake is delicious served at room temperature or slightly warmed in the microwave for 10-15 seconds.

Frequently Asked Questions

Can I make this cake in a different pan?

Yes, you can make this in two 9-inch round pans to create a layer cake, or as cupcakes. Adjust the baking time accordingly; cupcakes will take around 18-22 minutes, and round pans will take 25-30 minutes.

Do the marshmallows completely disappear?

Mostly, yes. The miniature marshmallows melt into the batter as it bakes, creating little pockets of moisture and sweetness that contribute to the cake’s unique, ultra-moist texture. You won’t find whole marshmallows in the finished cake.

Can I make this cake ahead of time?

Absolutely! This cake is actually even better on the second day as the flavors have more time to meld together. It’s a perfect make-ahead dessert for any occasion.
