I have been asked to bake 12 of these bite size burger cupcakes for a birthday.  They have to be vegan (no egg or dairy).  Cupcake buns, brownie burger patties, coconut lettuce, and icing condiments.  Any input for a fair price to charge her?  I may also make cookie fries.

A$10 apiece with fries.

They're cute! ... This topic has been discussed extensively. Use the search box and type in "how to price cakes" or "jason_kraft pricing cakes" and you'll learn how to do the math. 

Thanks

$15 each plus whatever the fries would be. Or eleventy million, whichever is less. These orders are always more work than you think they're going to be.  And don't forget about packaging.

And what you pay yourself per hour for the time it takes you to make them.
