Jazzing up a plain boxed cake mix can make a quick dessert taste almost as good as a gourmet bakery treat. Add instant pudding to the cake mix for a moister, denser cake. These cakes are best served with a light frosting, because they're too heavy to use for layer cakes or filled cakes. Although some cake mixes already come with pudding in the mix, they generally cost more than plain cake mix. You can add pudding to any standard boxed cake mix to save a few cents and create your own flavor combinations.
Mix one box of dry cake mix with one box of instant pudding in the desired flavor. You can add vanilla pudding to any cake mix flavor. Other options include lemon or banana pudding with a yellow cake mix, or chocolate or mint pudding with a chocolate cake mix.
Add the wet ingredients as directed on the box, including eggs, water or oil, depending on the brand of mix. Add one extra egg to the ingredients listed on the box to add the extra moisture necessary for the pudding mix.
Stir the mix until the dry ingredients are wet and the mix has a smooth consistency. Add up to 1/3 cup of water, 1 teaspoon at a time, if the mix is dry and doesn't have the consistency of a thick but pourable batter.
Pour the batter into the prepared cake pan. For cupcakes, fill the cupcake tins 2/3 full.
Bake the cake for the time recommended on the box for your pan size. Insert a toothpick into the center of the cake at the end of the baking time. If the toothpick comes out clean, the cake is done. Otherwise, continue to cook and check the cake in 3-minute intervals until the toothpick comes out clean. You may need a longer cooking time when you add the extra egg and pudding mix.
Before you begin, preheat the oven to the temperature indicated on the cake mix box. Grease your cake pan or cupcake tin. Dust the greased pan lightly with flour for a white or yellow cake, or dust lightly with cocoa powder for a chocolate cake.
Cool the cake in the pan on a wire rack for 5 to 10 minutes. Turn the pan over onto a cake plate and lightly thump the bottom until the cake slides out of the pan. Cool completely before frosting and serving.
Cakes made with the addition of a pudding mix will shrink a little as they cool.
