Preheat your oven to 350 degrees
Whisk 1/4 cup of vegetable oil, 1/4 cup of whole milk and a large egg in a large bowl until completely combined
Add a teaspoon of vanilla extract and 1/2 cup of brown sugar and whisk until fully incorporated
Add 1 cup of cake or all purpose flour, 1/4 teaspoon of baking soda, 3/4 teaspoon of baking powder, 3 tablespoons of natural unsweetened cocoa powder and a pinch of salt and whisk until mostly combined
Add 1/3 cup of hot coffee or water and mix until fully combined
Transfer the batter into a greased and parchment lined 9”x5” loaf pan or 8” or 9” round or square baking pan
Bake the cake in a 350 degree oven for 32-35 minutes for a loaf pan or 22-25 minutes for a round or square pan
Once a toothpick comes out of the center of the cake clean, transfer the cake to a cooling rack and let cool fully before frosting
Make the frosting by creaming a tablespoon of room temperature butter with 1/4 cup of cold heavy cream, 1/2 teaspoon of vanilla extract, 2 tablespoons of cocoa powder and 1 1/4 cup of confectioners sugar with an electric hand mixer until you have a creamy chocolatey frosting.
Once the cake has fully cooled, add your frosting and enjoy!
