Oh my yumminess. I’ve never seen anything like these summer milkshake ideas from PopSugar. I really don’t know which idea to try first. The first one with the sprinkle rim brings the fun of funfetti cake to a milkshake. Then, the second one blew me completely out of the water with the unexpected addition of toasted marshmallows. Then third involves grilled fruit – need we say more? Which on will you try first?
