Ingredients:

  • 1 box (15.25 oz / 432g) spice cake mix
  • 1 cup (240ml) fresh orange juice
  • 1/2 cup (115g) vegetable oil
  • 3 large eggs
  • 1 tbsp (6g) fresh orange zest
  • 1 tsp (2g) ground cinnamon
  • 8 oz (225g) cream cheese, softened
  • 1/2 cup (115g) unsalted butter, softened
  • 3 cups (360g) powdered sugar
  • 1 tsp (5ml) orange extract
  • 1 tbsp (6g) fresh orange zest

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease your 9x13 pan with butter or non-stick spray to ensure a clean release.
  2. In a large bowl, combine the spice cake mix, orange juice, oil, eggs, zest, and extra cinnamon. Beat on medium speed for about 2 minutes until the batter is smooth and glossy.
  3. Pour the batter evenly into the prepared pan and bake for 30-35 minutes until the edges are golden brown and the center springs back when lightly touched.
  4. While the cake cools completely, beat the softened cream cheese and butter until fluffy. Gradually add powdered sugar, orange extract, and zest.
  5. Once the cake is cool to the touch, spread the frosting in a thick, velvety layer across the top.
