Cake Batter
- 8 tablespoons (113g) unsalted butter, softened
- 2 tablespoons (25g) vegetable oil
- 1 package King Arthur Gluten-Free Yellow Cake Mix
- 4 large eggs
- 2/3 cup plus 2 tablespoons (180g) milk, divided
Chocolate Swirl Mixture
- 1/4 cup (21g) Dutch-process cocoa powder
- 1/4 cup (28g) confectioners’ sugar
- Preheat and prepare pan: Preheat your oven to 350°F (177°C). Grease a 10-cup Bundt pan thoroughly to ensure the cake releases easily once baked.
- Mix butter and oil: In a large mixing bowl, use an electric mixer to beat the softened butter and vegetable oil together until well combined and creamy.
- Add half the cake mix: Add half of the gluten-free yellow cake mix to the butter and oil mixture, beating until smooth and fully incorporated.
- Incorporate eggs one at a time: Reduce the mixer speed to low. Add the eggs one at a time, ensuring each egg is fully mixed in before adding the next to maintain a smooth batter.
- Add milk and remaining mix: With the mixer on low, add about one-third cup (76g) of the milk, then the rest of the cake mix. Beat until smooth. Follow by mixing in another one-third cup (76g) of milk until batter is well blended.
- Separate vanilla batter: Transfer 3 cups of the batter to a separate bowl and set aside for the vanilla portion of the cake.
- Prepare chocolate batter: Sift together the Dutch-process cocoa powder and confectioners’ sugar. Add this to the remaining batter along with the last 2 tablespoons (28g) of milk. Mix until smooth and uniform.
- Layer the batters: Alternate spoonfuls of the vanilla and chocolate batters into the prepared Bundt pan, turning the pan as you go to evenly distribute the batter. Fill the pan about two-thirds full. Tap the pan gently on the counter two to three times to settle the batter and remove air bubbles.
- Bake the cake: Place the pan in the preheated oven and bake for 45 to 48 minutes, until a long skewer inserted into the center comes out clean and a digital thermometer reads 205°F (96°C) at the thickest part of the cake.
- Cool the cake: Remove the cake from the oven and let it cool in the pan for 10 minutes. Then invert it onto a wire rack and allow it to cool completely before slicing.
- Storage: Store leftover cake well wrapped at room temperature for several days or freeze to keep longer. Thaw frozen cake at room temperature before serving.
Notes
- Ensure all ingredients are at room temperature for better batter consistency.
- Use Dutch-process cocoa for richer chocolate flavor and smooth texture.
- Greasing the Bundt pan thoroughly is crucial to prevent sticking and to preserve the beautiful swirl design.
- If you don’t have a digital thermometer, the skewer test is reliable to check doneness.
- For a dairy-free variation, substitute milk and butter with suitable alternatives, but texture may vary.
