What does instant pudding in cake do for the cake?

* Moisture: Instant pudding mix contains cornstarch, which absorbs moisture and creates a tender, moist cake.

* Flavor: The pudding mix adds a subtle flavor to the cake, depending on the flavor of pudding you use.

* Density: It also adds a bit of density and richness to the cake.

However, there are some caveats:

* Texture: The addition of pudding mix can make the cake slightly denser and more cake-like. It won't have the same light and airy texture as a standard cake.

* Sweetness: Pudding mix is already sweet, so you might need to reduce the amount of sugar in your recipe to avoid an overly sweet cake.

Overall, using instant pudding in cake can be a great way to add moisture, flavor, and a touch of density. However, be aware of the slight changes in texture and sweetness it might bring.
