Ingredients

Scale

Wet Ingredients

  • 8 tablespoons (113g) unsalted butter, softened
  • 2 tablespoons (25g) vegetable oil
  • 4 large eggs
  • 2/3 cup plus 2 tablespoons (180g) milk, divided

Dry Ingredients

  • 1 package King Arthur Gluten-Free Yellow Cake Mix
  • 1/4 cup (21g) Dutch-process cocoa
  • 1/4 cup (28g) confectioners’ sugar

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 10-cup Bundt pan thoroughly to ensure the cake releases easily after baking.
  2. Mix Butter and Oil: In a large mixing bowl, use an electric mixer to beat the softened butter and vegetable oil together until smooth and creamy.
  3. Add Cake Mix and Eggs: Add half of the gluten-free cake mix to the butter-oil mixture and beat until smooth. Reduce speed to low, then add the eggs one at a time, mixing each in completely before adding the next.
  4. Add Milk and Remaining Cake Mix: With the mixer on low, pour in about 1/3 cup (76g) of the milk. Beat in the remaining cake mix until smooth, then add another 1/3 cup (76g) of milk and mix well.
  5. Separate Batter: Transfer 3 cups of this batter into a separate bowl and set aside for the vanilla portion.
  6. Prepare Chocolate Batter: Sift together the Dutch-process cocoa and confectioners’ sugar. Add this mixture along with the remaining 2 tablespoons (28g) of milk into the original batter bowl, mixing until smooth to create the chocolate batter.
  7. Layer Batter in Pan: Alternate spoonfuls of vanilla and chocolate batter into the prepared Bundt pan, rotating the pan as you go to distribute the batter evenly. Fill the pan about two-thirds full. Gently tap the pan on the counter two or three times to settle the batter.
  8. Bake: Bake in the preheated oven for 45 to 48 minutes. Test doneness by inserting a long skewer or toothpick; it should come out clean. A digital thermometer inserted in the center should read 205°F (96°C).
  9. Cool: Remove the cake from the oven and let it cool in the pan for 10 minutes. Then invert the cake onto a wire rack to cool completely.
  10. Storage: Store any leftover cake wrapped well at room temperature for several days or freeze for extended storage.

Notes

  • Ensure the butter is softened for easier mixing and better texture.
  • Use a toothpick or skewer to check for doneness to avoid undercooking or overbaking.
  • Tapping the pan before baking helps eliminate air bubbles and evens out the batter.
  • For extra flavor, consider adding 1 teaspoon of vanilla extract to the vanilla batter.
  • If you do not have a Bundt pan, a similarly sized tube pan can be used instead.
