Coca Cola Cake

This Coco Cola Cake recipe is a staple for Dr Peggy Brunache. Although it is incredibly easy to make, this American southern dessert is not for the faint of heart! Only those with a sweet tooth and chocoholic tendencies can appreciate this American treat! It’s a rich, moist traybake that sits somewhere between a brownie and a sponge. It’s become a chocolate staple at the Southern Fried Food Festival, and the recipe comes with a warning: be prepared to make this again and again for your family and friends.

Recipe from Food Historian and Culinary Consultant Dr Peggy Brunache

Coca Cola cake
Prep time: less than 10 mins
Bake time: 30 mins
Servings: 24 slices

• 245ml Coca-Cola
• 118ml buttermilk
• 226g butter, softened
• 320g caster sugar
• 2 large eggs, lightly beaten
• 2 tsp vanilla paste*
• 250g self-raising flour
• 45g cocoa powder + extra for dusting traybake tin
• 1 tsp baking soda
• 75g miniature marshmallows
• Coca-Cola Frosting (recipe to follow)

* 1 tbsp. vanilla extract will substitute


Preheat oven to 180 Celsius/Fan 160 Celsius/Gas 4.
Combine Coca-Cola and buttermilk; set aside.


Beat butter at low speed with an electric mixer or by hand until creamy. Gradually add sugar; beat until blended. Add egg and vanilla; beat at low speed until blended.


Combine flour, cocoa, and baking soda. Add to butter mixture alternately with cola mixture; continue with flour mixture. Beat at low speed just until blended.


Stir in marshmallows with a large spoon. Pour batter into a greased and cocoa-dusted 13- x 9-inch traybake tin.


Bake for 30 minutes or check by inserting a toothpick around the 20-25 minute mark. If the toothpick comes out wet, bake longer. Toothpick into the warm, moist cake may come out sticky, which is fine. But it should not be wet like mud.


Once done, remove from oven; cool 10-15 minutes. Make Coca-Cola frosting then pour immediately over warm cake.
Note: Don’t make the frosting too far in advance–you need to pour it over the cake shortly after baking.

Coca-Cola Frosting

• 114g butter
• 80g Coca-Cola
• 3 tbsp. cocoa
• 230g icing sugar
• 1/2 tbsp. vanilla paste*

*1 tbsp. of vanilla extract will substitute


Bring first 3 ingredients to a boil in a large saucepan over medium heat, stirring until butter melts. Remove from heat; whisk in sugar and vanilla.
