Ingredients
Method
1. Heat your oven to 350°F (175°C) and generously grease a 9×13-inch baking pan.
2. Add the cake mix, water, egg whites, oil, sour cream, and clear vanilla to a large bowl or stand mixer. Mix on low speed until combined, then increase to medium speed and beat for about 2 minutes, scraping down the bowl as needed.
3. Pour 2 cups of plain batter into the prepared pan. Divide the remaining batter evenly into three small bowls. Tint each bowl with a different food color, mixing until smooth and evenly colored.
4. Spoon random dollops of each colored batter over the white base. Using a butter knife, gently drag it through the batter in loose motions to create swirls. Less is more—overmixing will blend the colors instead of swirling them.
5. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely before frosting.
6. Frost the cooled cake, add festive Easter sprinkles or candy, and serve!
Notes
Tips & Storage
- Keep the cake covered in the refrigerator for up to 4 days. It can be enjoyed cold or at room temperature, but refrigeration is best for the frosting.
- This recipe works for other holidays too—just change the colors and decorations.
- Stick to no more than three contrasting colors to keep the swirls clean and visible.
- Go easy on food coloring. A few drops go a long way, and too much can affect flavor.
FAQs
How do you create a swirl pattern in a cake?Start with a base layer of plain batter, then spoon colored batter on top. Drag a knife gently through the batter to create a marbled look. The swirls bake right into the cake. Can this cake be frozen?
Yes—this cake freezes best without frosting. Line the pan with parchment paper before baking. Once cooled, lift the cake out, wrap it tightly, and freeze for up to 3 months. Thaw completely, then frost and decorate before serving.
