Easy Chocolate Cake (One Bowl, No Mixer)

Jump to Recipe

The best easy chocolate cake is a one-bowl, oil-based cake with hot coffee stirred in — it’s deeply moist, intensely chocolatey, and needs no mixer. The hot liquid blooms the cocoa for richer flavor and makes the batter very thin, which is the secret to that tender, fudgy crumb. Whisk it together and bake.

The Quick Version

• Hot coffee blooms the cocoa for deep chocolate flavor (water works too).
• Thin batter is correct — it’s what makes the cake moist.
• One bowl, one whisk, no mixer.
• Oil keeps it moist for days.

How to make it

1. Heat oven to 350°F (175°C); grease a 9×13 pan. Whisk flour, sugar, cocoa, baking soda, baking powder and salt.
2. Whisk in eggs, milk, oil and vanilla until smooth.
3. Stir in 1 cup hot coffee or boiling water last — the batter will be thin.
4. Bake 30–35 minutes until a toothpick is clean. Cool completely before frosting.

Foolproof tip: don’t panic at the runny batter — adding flour to thicken it is the single most common way people ruin this cake.

Frequently asked questions

Why put coffee in chocolate cake?

It deepens chocolate flavor without tasting like coffee, and the hot liquid blooms the cocoa. Boiling water works the same for texture.

Why is my batter so thin?

That’s correct — the thin batter is the secret to a moist crumb. Don’t add flour or the cake turns dry.

What frosting is best?

Chocolate buttercream is classic; cream cheese frosting, ganache or whipped cream all work.
