I recently made Vietnamese popsicles and they took me back to life on the island! Trust me these are for Adults only unless you want to have very hyper children!
I buy this expresso from Marci's Italian Deli and made 2 cups. Then added sweetened condensed milk until it's carmel colored. (it didn't take very much). Then poured it into my molds. It made more then 6 so I poured it into ice cube trays. On a hot day I'll use the ice cubes in a glass of Almond milk, or for a banana, coffee smoothie.
The coffee tastes surprisingly close to the expensive Starbucks small bottles you can buy in the grocery store. So you might want to bottle some too!
