Coca

Preheat your oven to 350°F (175°C).

In a large bowl, whisk together the all-purpose flour, granulated sugar, and baking soda.

In a saucepan over medium heat, combine 1/2 cup salted butter, vegetable oil, 1 cup Coca-Cola, and 1/4 cup cocoa powder. Bring to a boil, stirring until smooth.

Pour the hot chocolate mixture into the dry ingredients and mix with a hand mixer until combined.

Add the buttermilk and mix for 30 seconds.

Mix in the eggs and 1 teaspoon of vanilla extract until just combined.

Grease a 13x9 inch baking dish. Pour the batter into the prepared dish.

Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

While the cake is baking, prepare the frosting. In a saucepan, combine the remaining 1/2 cup salted butter, 1/4 cup cocoa powder, and 1/4 cup Coca-Cola. Bring to a boil over medium heat, stirring constantly.

Remove from heat and pour the mixture over the powdered sugar in a separate bowl. Add the remaining 1 teaspoon of vanilla extract.

Whisk until the frosting is smooth and creamy.

Once the cake is done, let it cool for a few minutes. While the cake is still warm, pour the frosting over the top.

Spread the frosting evenly to cover the entire cake. Let it set before slicing.

Slice and serve, optionally with a scoop of vanilla ice cream.
