Scarlet mentioned jars last year, putting in packets of the right ingredients and put the instructions on the outside. I really liked the idea, especially for kids, or adults who don't normally do a lot of baking. It takes out the hard work of them looking up a recipe, buying ingredients, weighing out etc... this will give them an interest in cooking, and they have a recipe they can keep and use over and over.
This e-book I got has hundreds of ideas for recipies that don't have too many ingredients so it all fits nicely in a jar. You could even print out the instructions to put on the jar!
