How to bake mini cupcakes without the right pan?

I need to bake mini cupcakes but I don't have the mini cupcake pan, just the regular one and flat trays. How do i bake them?|||If you can find mini FOIL cupcake liners, those will do the trick. Remove the paper liner from the foil liner, place on a baking sheet, fill with cupcake batter, and bake.|||you will need the pans if you want to make the cupcakes, the batter will ooze over the liners if you don't have something to support them.|||You could try putting the mini cupcake wrtppers in the larger trays and seeing if they hold, or, put the all very close together in a cake circle for support off one another
