Ingredients

Scale
  • 2 cups (240 g) all-purpose flour
  • 1 ¾ cups (350 g) granulated sugar
  • ¾ cup (75 g) unsweetened cocoa powder
  • 1 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 2 large eggs, room temperature
  • 1 cup (240 ml) buttermilk (or milk + 1 tbsp vinegar)
  • ¾ cup (180 ml) fresh orange juice
  • ½ cup (120 ml) vegetable oil
  • 2 teaspoons vanilla extract
  • ½ cup (115 g) unsalted butter, softened
  • 8 oz (225 g) cream cheese, softened
  • 3 cups (360 g) powdered sugar, sifted
  • 2 teaspoons fresh orange zest
  • 2 tablespoons fresh orange juice
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch (23×33 cm) sheet pan and line it with parchment paper.
  2. In a large bowl, sift together 2 cups all-purpose flour, ¾ cup cocoa powder, 1 ½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt. Whisk to combine.
  3. In a separate bowl, whisk 1 ¾ cups granulated sugar with 2 large eggs until light and fluffy (about 2 minutes).
  4. Add ½ cup vegetable oil, 1 cup buttermilk, ¾ cup fresh orange juice, and 2 tsp vanilla extract to the sugar and eggs. Mix until smooth.
  5. Slowly fold the dry ingredients into the wet mixture with a spatula until just combined. Do not overmix.
  6. Pour the batter evenly into the prepared sheet pan and smooth the top.
  7. Bake for 30-35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. The cake should spring back lightly when pressed.
  8. Cool the cake completely in the pan on a wire rack, about 1 hour.
  9. To make the frosting, beat ½ cup softened unsalted butter and 8 oz softened cream cheese until creamy and smooth (about 3 minutes).
  10. Gradually add 3 cups powdered sugar, beating well after each addition.
  11. Mix in 2 tsp fresh orange zest, 2 tbsp fresh orange juice, and 1 tsp vanilla extract. Adjust consistency with more powdered sugar or juice if needed.
  12. Spread the frosting evenly over the cooled cake. Chill for 15 minutes before slicing for a neat finish.

Notes

Use fresh orange juice and zest for best flavor. Room temperature ingredients help achieve smooth batter and frosting. Do not overmix the batter to keep the cake moist and tender. Frost only when the cake is completely cooled to avoid melting the frosting. For extra orange flavor, sprinkle a pinch of coarse sea salt over the frosted cake before serving. The cake can be made gluten-free by substituting almond flour and dairy-free by using plant-based alternatives.
