@fify-- Making vanilla pudding is actually not difficult. It just requires milk, egg yolks, sugar, corn starch, butter and vanilla extract. The ingredients have to be mixed and cooked on the stove to thicken.
If you want, there are also cook and serve versions at the grocery which require just adding milk and cooking it on the stove top for a a few minutes. These taste much better than the instant mixes and also save time.
But if you don't mind a few extra steps, you can easily make it yourself and it will be delicious. There is nothing like fresh vanilla pudding. I make mine with real vanilla beans and I like to cook it a little longer than usual. I enjoy having it very thick, more like a custard.
