Step-by-Step Instructions

Preheat and Prepare Pans

Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, ensuring even coverage to prevent sticking.

Combine Dry Ingredients

In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until evenly distributed.

Add Wet Ingredients

Add eggs, milk, vegetable oil, and vanilla extract. Beat on medium speed for about 2 minutes until smooth and well incorporated.

Incorporate Boiling Water

Carefully stir in boiling water until fully combined. The batter will be thin—this is essential for a moist crumb.

Bake the Cake Layers

Divide batter evenly between prepared pans. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.

Cool Completely

Allow cakes to cool in pans for 10 minutes before transferring to a wire rack. Cool fully before frosting to prevent melting.

Prepare the Frosting

Beat softened butter until creamy. Gradually mix in powdered sugar and cocoa powder on low speed, then add heavy cream and vanilla. Beat on medium speed until light and fluffy.

Assemble the Cake

Place one cake layer on a serving plate and spread an even layer of frosting on top. Add the second layer and frost the top and sides evenly. Decorate as desired.

Recipe Notes & Tips

Do Not Overbake – Remove once a toothpick comes out clean to retain moisture.
Room Temperature Ingredients – Ensures smoother batter and even baking.
Chill Before Slicing – Brief refrigeration helps achieve cleaner cuts.
Level the Layers – Trim domed tops for a professional finish.

Troubleshooting Common Issues

Frosting Too Thick – Add a tablespoon of cream at a time until spreadable.
Cake Sinking in Center – Oven door opened too early or underbaked center.

Why This Recipe Works

This cake achieves its signature moistness through the use of oil rather than butter, which remains liquid at room temperature and keeps the crumb soft. The combination of baking powder and baking soda ensures proper lift, while boiling water blooms the cocoa powder, intensifying flavor and creating a smooth, fluid batter that bakes into a tender structure. The balanced ratio of fat, sugar, and flour produces a cake that is rich yet light. At approximately 550–600 calories per slice, it’s an indulgent dessert best enjoyed in moderation or served in smaller portions for a lighter option.

Final Thoughts

Moist Chocolate Cake is a timeless dessert that combines simplicity with irresistible flavor. Its tender crumb, bold chocolate notes, and creamy frosting make it suitable for everything from birthdays to casual gatherings. For a lighter approach, reduce frosting thickness or pair with fresh fruit for balance. However you serve it, this cake is guaranteed to satisfy every chocolate lover.
