I want to bake with my daughter. How can I find the best cupcake recipe for kid?

You might want to try this one: http://allrecipes.co.uk/recipe/587/easy-kids-cupcakes.aspx?o_is=Hub_TopRecipe_5 Your daughter can help you with putting the ingredients in the bowl, letting her mix (right after the mixture is done, of course) to let her experience how is it like, and decorate the cupcake once baked. Make sure to have a variety of colourful toppings/icings and let her imagination and creativity do the work. Enjoy!
