  • 2 cups (400g) granulated sugar
  • 1½ tsp baking powder
  • 1½ tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup (240ml) whole milk
  • ½ cup (120ml) vegetable oil
  • 2 tsp vanilla extract
  • 1 cup (240ml) boiling water or hot coffee

Directions

Make the Cake:

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large bowl, mix the flour, cocoa powder, sugar, baking powder, baking soda, and salt together.

  2. Gradually add the cocoa powder and powdered sugar, mixing on low until combined.
