To make your cup of store-bought hot chocolate extra delicious and as creamy as possible, turn to a single ingredient: sweetened condensed milk.

Sweetened condensed milk can help hot chocolate achieve a new level of richness while staying true to its classic taste. It's also a great way to thicken a watery cup.

Treat this ingredient as a mix-in rather than a replacement for milk. Since it's super sweet, you may want to be judicious about how much you spoon into your cocoa.

A couple of tablespoons could be all you need to make hot chocolate creamier and thicker, but you can add a few more if you’re using a dark chocolate mix.
