Review RecipeBusy Day Chocolate Cake

Table of Contents
This classic busy day chocolate cake is an old-fashioned dessert I stole from my Southern grandma’s recipe box (try our amazing chocolate dump cake, too!). It’s a favorite that is quick and easy to make and comes out moist with a rich frosting on top. It has a secret ingredient, coffee, that enhances all of that delicious chocolate flavor. You’ll love this simple, yummy cake.

BUSY DAY CHOCOLATE CAKE INGREDIENTS

You’ll need:
For the Cake:
- 2 cups white sugar
- 2½ cups all-purpose flour
- 4 tablespoons unsweetened cocoa powder
- 1½ teaspoons baking soda
- 1½ teaspoons baking powder
- 1 teaspoon salt
- 2 eggs, room temperature
- 1 cup buttermilk
- 2 teaspoons vanilla
- 1 cup hot coffee
- 1 cup vegetable oil
For the Icing:
- ½ cup butter, softened
- ½ cup cocoa powder
- 3 cups powdered sugar
- 2 tablespoons coffee
- ½ tablespoon vanilla extract
SUBSTITUTIONS AND ADDITIONS
BUTTERMILK: You can make your own buttermilk using whole or 2% milk and lemon juice or distilled vinegar. For every 1 cup of milk, stir in 1 tablespoon of lemon juice or vinegar.
CHOCOLATE CHIPS: Add a little bit extra to this moist chocolate cake with chocolate chips mixed into the batter.
NUTS: If you like nuts in your cake, add chopped walnuts or pecans to your cake batter.
COFFEE: If you absolutely do not want to use coffee in this recipe, you can substitute the same amount of hot water for the coffee

HOW TO MAKE THIS BUSY DAY CHOCOLATE CAKE RECIPE
For the Cake:
STEP ONE: Preheat oven to 375°F and grease a 9×13-inch cake pan by rubbing shortening on the pan and using cocoa powder to dust the pan instead of white flour.
PRO TIP
Rubbing cocoa powder on the pan instead of flour keeps the chocolate flavor going.
STEP TWO: Using a large bowl combine the sugar, flour, cocoa, baking soda, baking powder, and salt. Whisk the dry ingredients together.

STEP THREE: Add the eggs, buttermilk, vanilla, coffee, and oil. Beat on medium speed with an electric mixer for about two minutes, the batter will be thin.
STEP FOUR: Pour batter evenly into the prepared pan.

STEP FIVE: Bake in the preheated oven for 30-40 minutes or until a cake tester inserted into the center of the cake comes out clean.
STEP SIX: Cool 10 minutes in the pan before icing.

For the Icing:
STEP ONE: In a medium saucepan on medium-low heat melt the butter. Remove from heat. Whisk in cocoa powder. Return to stove on medium-low heat and cook until just begins to boil.
STEP TWO: Remove from heat. Whisk in the powdered sugar — you can sift it to remove any lumps before adding. Add the vanilla and coffee and stir until mixed.
STEP THREE: Let the frosting cool for 10 minutes to let it set up just a bit.
PRO TIP
Don’t let the icing cool too long or it will harden in your pan and not be easy to spread.
STEP FOUR: Spread the icing over the cake.
HOW TO SERVE
This delicious cake is perfect with a freshly brewed cup of hot coffee. You could also serve the warm cake and add a scoop of vanilla ice cream or whipped cream. During the holidays, you can serve this with a scoop of peppermint ice cream. During the spring, add fresh berries.

STORAGE
ON THE COUNTER: This simple cake will store in an airtight container on the counter for three days.
IN THE FREEZER: You can freeze this cake, either in slices or as a whole. If you plan to freeze a frosted cake, it is helpful to freeze the cake unwrapped first, and then to wrap the frozen slice or pan once the frosting will no longer transfer to the wax paper or other wrapper.

This busy day cake is so simple to make but it tastes absolutely amazing! The cake is dense and moist, with the perfect balance of sweet and chocolate richness. The homemade icing is everything. It’s so good, I could happily eat it with a spoon on its own. Whip this up the next time you are craving chocolate or even for special occasions.

Comments
SheriO says
The recipe says bake 30-40 min at 375. The comments say 350. The picture appears to say 10 min at 350. You make HOT coffee and mix it with the eggs?
Layne Kangas says
So sorry for the mix up – it is bake at 375. And yes, you make the coffee and add it in!
Zoe says
Looks good
Going to make it for work
Thanks for sharing zx
Chris says
It says “To make homemade buttermilk, whisk 2 teaspoons of apple cider vinegar with enough whole milk or half and half to make 1/2 cup of liquid.”
The recipe calls for 1 cup of buttermilk….so would you add 4 teaspoons of apple cider vinegar with enough whole milk/half and half to make 1 cup of liquid?
Layne Kangas says
Yes!
Stein says
When making the frosting is it 2 TBSPS of coffee made or instant dry crystals you mix in?
Thanks!
Layne Kangas says
It’s already brewed coffee 🙂 Enjoy!
Beth says
Ingredients call for both baking soda and baking powder, yet instructions just say to add baking soda…no mention of adding the baking powder?
Layne Kangas says
Hi, Beth – you add them both in step two when you combine the dry ingredients. Enjoy!

Peter says
Wonderful recipes!
jamie says
I have made this cake a few times now and people absolutely rave about it. It is extremely moist and delicious and full of flavor. This last time I made it I did the cocoa powder in place of regular flour on the pan and it definitely made a difference in flavor. Everyone asks for the recipe.
Sarah says
I’m so excited to have found this recipe. My grandma used to make this and always had it in the freezer. I got the recipe from her before she passed many years ago and lost it during one of my moves. I’ve looked and found some that were similar but they just weren’t right. This is it and it’s perfect. Thank you for sharing…I’m not losing it this time
