How To Make A Boxed Cake-Mix Better

There's nothing like the convenience of a store bought mix. It's economical, stores well, and (if made right) always has a dependable outcome. But did you know that with a few extra ingredients, you can regenerate a cake-mix cake into one that tastes like it's from the bakery, or even better?

That's right! It becomes a much fluffier, moister, and higher-rising cake by mixing those pre-packaged ingredients with an extra egg, a small box of instant pudding, and some mayonnaise.

Yep, mayonnaise! It's the oil that makes it so moist and tender. If you'd like to make your own homemade mayonnaise, check out this recipe. It's fresh and delicious with a Cajun kick!

Ingredients of mayonnaise, water, eggs, and a bowl of cake mix.

This time, we're using a banana cream instant pudding mix for our Banana Pudding Cake. For any other cake mix flavor like chocolate or strawberry, use vanilla flavored pudding instead.

I hope you try these ingredients with your next cake. It's so easy to remember. This is how I memorized the ingredients; start with 1 cake mix and 1 instant vanilla pudding, and then I remember the rest of the elements with a 1,2,3:

1 cup of water,

2/3 cup mayonnaise, and

3 eggs

Somehow this helps my brain recall the ingredient amounts easily. Maybe it'll help you, too!

More Banana Flavor

Next, we top the baked layer with a filling of mashed bananas and sugar. Nothing more! The idea came from a friend who was raised in Roberts Cove, a German community near Crowley, Louisiana. She recently shared with me her favorite cake her mama used to bake. It had many thin cake layers with this banana filling in between each one. Then it was covered with a box of Betty Crocker Home Style Fluffy White Frosting Mix that tastes like marshmallow cream. Sounds yummy, doesn't it?

I love hearing and sharing about the foods we Cajuns grew up eating in the different regions of Louisiana. (Thanks, Rose!)

This recipe came about by accident. One day, I was making a cake-mix cake and realized I only had banana cream instant pudding instead of plain vanilla. I thought of Rose's mama's cake and decided to add the banana filling and the fluffy white frosting. To my surprise, the cake tasted just like banana pudding. Horray!

More About The Frosting

This frosting is divine! It tastes like white clouds of marshmallow cream. The only thing needed is a box of Betty Crocker Home Style Fluffy White Frosting Mix beaten with ½ cup of boiling water. It whips in minutes and is soo fun to spread around.

Delicious and a-m-a-z-i-n-g!

Oh, what a cake!

It's got the hallmark of a good banana pudding. There's the taste of banana in the super-moist, mouth-watering cake, and in the creamy filling. Plus, the frosting is the icing on the cake! And to give it more of that banana pudding smack, it's topped with crushed vanilla wafers and refrigerated until it's good and cold.
