Preheat the oven to 350° F. Add the cupcake liners to the cupcake tin. Set aside.
To the bowl of a stand mixer, add the dry ingredients - sugar, flour, cocoa, baking powder, and salt.
3 cups sugar, 3 cups flour, 1 ½ cups cocoa powder, 1 tbsp baking powder, 1 tsp salt
Whisk well to combine.
Now add the liquid ingredients - the eggs, oil, milk, water, and vanilla.
4 eggs, ½ cup oil, 2 tsp vanilla, 1 ½ cup milk, 1 ½ cup water
Mix on low for about 1 minute and then increase the speed and beat for another 2 minutes. Stop the mixer, scrape down the sides of the bowl and beat again.
Fill each cupcake liner to ⅔ full. Bake for about 14-16 minutes or until the toothpick inserted in the center comes out clean.
Allow the cupcakes to cool completely before decorating.
