Instructions

For the Buttermilk Cake

Grease a 9x13-inch pan and set aside.
In a mixing bowl, combine the flour, baking powder, and baking soda; set aside.
2 1/4 all-purpose flour, 2 teaspoons baking powder, 1/2 teaspoon baking soda
In a separate bowl, whisk together the eggs, oil, and vanilla; set aside.
3 eggs, 2 tablespoons vegetable oil, 1 tablespoon vanilla extract
In the bowl of a stand mixer (or use a hand mixer with a large mixing bowl), cream the butter and sugar.
1 cup salted butter, 1 3/4 cup sugar
Add the mixture of eggs, oil, and vanilla and stir until combined.
Add about half of the dry ingredients and stir.
Add the buttermilk and stir until almost combined; finish by stirring in the remaining dry ingredients.
1 1/4 cup buttermilk
Stir until smooth, making sure to scrape down the sides of the bowl to incorporate all ingredients.
Pour into the prepared pan and smooth to an even layer.
Bake for 35 minutes. Press a toothpick into the center of the cake; if you get wet batter, bake another few minutes or until a toothpick is clean or has just a few moist crumbs.
Let cool for 15 minutes.

For the Caramel Frosting

Melt the butter in a saucepan over medium heat.
1/2 cup salted butter
Once melted, add the brown sugar and buttermilk and whisk until smooth.
1/2 cup brown sugar, 2 tablespoons buttermilk
Remove from the heat and add the powdered sugar.
1 1/2 cups powdered sugar
Whisk until smooth then pour over the warm cake; spread to an even layer.
Let cool completely then cut into slices and enjoy!

Notes

Make Your Own Buttermilk - To make your own buttermilk, add 2 tablespoons of white vinegar to a 2-cup liquid measuring cup. Add enough milk to make 2 cups and give it a stir. You won't need quite all of it, but can save it for another recipe, if desired.
