Ingredients:

  • 2 ¼ cups (280g) All-purpose flour
  • 1 ½ cups (300g) Granulated sugar
  • 3 ½ tsp (15g) Baking powder
  • 1 tsp (5g) Salt
  • ½ cup (115g) Unsalted butter, softened
  • 1 cup (240ml) Whole milk, room temperature
  • 3 Large eggs, room temperature
  • 1 tsp (5g) Vanilla extract
  • ¼ cup (60ml) Vegetable oil
  • 1 cup (170g) Powdered sugar
  • 3 tbsp (45ml) Cocoa powder
  • 2 tbsp (30ml) Melted butter
  • 3 tbsp (45ml) Milk

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease your 9x13 pan with butter or cooking spray and line the bottom with a strip of parchment paper for effortless release.
  2. Add the flour, sugar, baking powder, and salt directly into a large mixing bowl.
  3. Incorporate the softened butter, milk, eggs, vanilla, and oil into the dry ingredients.
  4. Beat on medium speed for about 2 minutes until the batter is smooth and pale yellow.
  5. Pour the batter into the prepared pan and smooth the top with a spatula.
  6. Bake for 30–35 minutes, or until the edges pull slightly away from the pan and a toothpick inserted in the center comes out clean.
  7. Allow the cake to cool completely in the pan on a wire rack.
  8. Whisk together powdered sugar, cocoa powder, melted butter, and milk to create the glaze, then spread evenly across the cooled cake.
