wontons stay crisp. Leftovers should be cooled completely and stored in an airtight container in the refrigerator for up to 3 days; reheat on a baking sheet in a 350°F (175°C) oven for 5–8 minutes until warmed and re-crisped. For food safety, keep the cream cheese and cheese refrigerated until you’re ready to mix, don’t leave the baked cups out at room temperature for more than about 2 hours at a party (or 1 hour if it’s very hot outside), and reheat leftovers to steaming hot before eating. Always discard any cups that have been sitting out too long or look or smell off.
My aunt brought these to a backyard cookout last summer and within 10 minutes the whole tray was gone and everyone was asking who made them.
