I have taken other recipes and baked them in different sized pans than what is called for. You might try looking for similar recipes online for ones baked as cupcakes , etc., so that you have an idea of how many the recipe would make and how long to bake  them. And you will certainly want to try the recipe as adjusted at home before class. 

But I think making these recipes as single serving size (to spread the word, so to speak) is a great idea!

Please come back and post what you have discovered to help future lesson bakers!
