I'm trying to find a dough that would hold it's shape in a muffin tin to make little cup shapesIs there any dough that does that? Would a pie crust do that or a pizza crust?
Pie crust, yesBiscuit or pizza dough, yes, but you'll need to weight it downPhyllo dough, yes, but again, weighting it down will be helpfulIt depends on the flavor you're looking forPie crust may break apart easilyYou could buy already shaped phyllo pastries or already made puff-pastry cups in the freezer section at the grocery storeTo weight down the dough when necessary, fill your tins with the dough, then add a larger square of aluminum foil and some dried beansBake as usual.
