Ridiculously Easy Caramel Buttermilk Sheet Cake

Return to Cake Recipes

Ingredients:

For the cake:

1 cup butter, cubed

1 cup water

½ cup buttermilk

2 large eggs

2 teaspoons Vain vanilla extract, I used our Sri Lankan Vanilla extracted in Dark Rum

1 teaspoon baking powder

¾ teaspoon salt

¼ teaspoon baking soda

2 cups sugar

2 cups all-purpose flour


For the caramel icing:

½ cup butter

1 cup dark brown sugar

¼ cup buttermilk

1 teaspoon vanilla extract, I used our Sri Lankan Vanilla extracted in Dark Rum

2 cups powdered sugar

Directions:

For the cake:

Preheat oven to 375˚F. Spray a 10x15 jelly roll pan or a sheet pan generously with baking spray and rub with a paper towel to coat all surfaces. Set aside.
In a medium-large microwave-safe bowl, combine the cubed butter and water. Microwave on high for 2 minutes. Most of the butter should be melted. Remove from the microwave and stir until butter is completely melted.


Add the buttermilk and whisk until well combined then add the eggs and whisk again.
Add the baking powder, baking soda, salt, vanilla extract and stir to combine.
Add the sugar and flour and whisk until smooth and lump-free. It will seem lumpy at first but keep stirring. It will get nice and smooth. A whisk works great for this.
Transfer to the prepared pan. Bake until golden brown and a toothpick inserted in the center comes out clean, 18-25 minutes. Cool on a wire rack for 15 minutes. 


For the caramel icing:


Toward the end of the baking time make the icing by combining the butter and brown sugar in a medium-size pot over medium heat.
Stir until the butter melts and the mixture comes to a boil. If the mixture seems separated, whisk vigorously to combine. Add the milk and return the mixture to a boil.
Turn off the heat and add the vanilla extract and the powdered sugar. Stir vigorously until the icing is smooth and there are no lumps.
Pour the icing over the warm cake and, working quickly, spread with the icing to cover the cake. (An angled cake knife works well for this.) Swirl the icing if desired. Once the icing starts to thicken, stop spreading and/or swirling. Allow the cake to cool and enjoy!
