This perfectly soft and fluffy white cake is made with a doctored-up cake mix, featuring mayonnaise and pudding mix. It's flavorful, tender, and easy to make!
Preheat oven to 325F and spray a bundt pan with baking spray, such as Baker's Joy. You can also butter and flour the pan instead of using spray. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment (or in a large mixing bowl with a handheld electric mixer), combine cake mix, dry pudding mix, mayonnaise, egg whites, and water. Mix on low speed for 30 seconds, then scrape down the sides of the bowl. Mix for 2 more minutes on medium-high speed.
Spread batter evenly in the prepared bundt pan. Bake in preheated oven for 45-50 minutes, or until a toothpick inserted in the center of the cake comes out clean.
Remove from oven and let the cake cool in the pan for about 10 minutes, then run a knife along the edge of the cake to ensure it's separated from the pan. Invert the cake onto a serving plate, then let the cake cool completely.
Once the cake is cooled, prepare the icing by combining the cream cheese, butter, and powdered sugar in a mixing bowl. Beat on medium speed until smooth. Add 4 tablespoons of milk, mixing well until incorporated. If needed, add more milk, 1 tablespoon at a time, until the desired consistency is achieved. You want it to be thin enough to spoon over the cake, but not so thin that it runs right off the cake.
Spoon the icing over the cake, letting it drip partially down the sides of the cake. Slice, serve, and enjoy!
Notes
Feel free to add sprinkles over the icing to make a festive birthday cake or holiday cake.
The icing is optional--you can omit it and simply dust the top of the cake with powdered sugar, if preferred.
You can bake this cake as cupcakes--decrease the baking time to 15-19 minutes, or until a toothpick inserted in the center comes out clean.
