Chocolate Layer Cake with Hot Coffee
Not rated yet. Be the first.
Hot coffee goes in last, and the batter turns thin enough to draw a small crowd around the bowl. Bake it anyway. Two deep, tender layers later, a finger is already swiping frosting from the back.
The short version
Whisk dry ingredients, stir in eggs, milk, oil and vanilla, then thin the batter with hot coffee. Bake in two 9-inch pans at 350°F for about 30 minutes, cool completely, and frost with chocolate buttercream.
What makes ours better
why ours wins the argument at dinner
-
Stir in hot coffee at the end. Hot liquid wakes up the cocoa so it tastes deeper and more chocolatey. The coffee itself disappears into the flavor. Hot water works if you have none.
-
Use oil instead of butter in the cake. Oil keeps the crumb soft straight from the fridge and for days afterward, and it means no creaming and no waiting for butter to soften.
-
Line the pans with parchment. A thin chocolate cake sticks. A parchment circle on the bottom of each pan lets the layers slide out whole every time.

Steps
go slow. the good part can’t be rushed.
-
Heat the oven, prep pans
Set a rack in the center of the oven and heat it to 350°F. Grease two 9×2-inch round cake pans, press a parchment circle into the bottom of each, and grease the parchment.
-
Whisk the dry ingredients
In a large bowl, whisk the sugar, flour, cocoa, baking soda, baking powder and salt until no cocoa lumps remain. Press out any stubborn lumps with the back of a spoon.
-
Add the wet ingredients
Add the eggs, milk, oil and vanilla. Whisk until the batter is smooth and thick, about 1 minute, scraping the bottom and sides of the bowl.
-
Thin with hot coffee
Pour in the hot coffee and whisk just until combined. The batter will be very thin, like heavy cream. That is correct.
Don't add more flour. The thin batter is what makes the cake moist.
-
Fill the pans and bake
Divide the batter evenly between the pans. Bake until a toothpick in the center comes out clean and the top springs back when pressed lightly, 28 to 33 minutes.
About 28 min. Cook mode has a timer for this step.
-
Cool completely
Cool the layers in the pans for 10 minutes. Run a knife around the edges, turn them out onto a rack, peel off the parchment and cool until completely cold, about 1 hour.
Frosting a warm layer melts the buttercream. Be patient here.
About 60 min. Cook mode has a timer for this step.
-
Beat the buttercream
Beat the butter until creamy, about 2 minutes. Add the cocoa and powdered sugar in two or three additions, mixing on low until it looks like thick sand. Add the milk, vanilla and salt, then beat on medium-high for 2 to 3 minutes until fluffy and spreadable. Add a spoonful more milk if it is stiff.
-
Fill and frost
Put one layer on a plate, flat side up, and spread about a cup of frosting over it. Set the second layer on top, bottom side up so the top is flat, and frost the top and sides. Chill 15 minutes to set, then slice with a hot, wiped knife.
Good to know
the stuff I’d tell you over the phone
- Both natural and Dutch-process cocoa work here. Dutch-process gives a darker, mellower cake.
- The batter is thin enough to pour straight from the bowl. Don't thicken it.
- For a simpler frosting, see classic american buttercream frosting and stir in cocoa to taste.
- Storage. Covered at room temperature, 2 days. In the fridge, 5 days; bring slices to room temperature before serving. Unfrosted layers wrapped well freeze for 3 months.
Questions, answered
asked and answered at the kitchen counter
Why is my chocolate cake dry?
Overbaking or too much flour. Spoon flour into the cup and level it, and check for doneness at 28 minutes. Pull it as soon as a toothpick comes out clean.
Can I use hot water instead of coffee?
Yes. The cake will taste slightly less deep but is still very good. Coffee does not make it taste like coffee.
Why is the batter so thin?
Hot liquid and oil make a pourable batter. It bakes into a soft, tender crumb, so don't try to thicken it.
Can I make the layers ahead?
Yes. Wrap the cooled layers tightly and keep them at room temperature for a day, or freeze them for up to 3 months. Frost the day you serve.
