Oh wow, that sounds amazing! I love the idea—first, let’s start with a splash of caramel syrup in the espresso shot so that sweet swirl kicks in right away. Then we can drizzle a rainbow of frothy foam: use a little food coloring—blue, green, yellow, orange, red—layer them gently on top. We’ll swirl them in with a tiny twist to make a swirl that looks like a rainbow, but the caramel stays underneath for that sweet flavor. And maybe we’ll finish with a dusting of edible glitter to make it sparkle. I’m all in—let’s brew up some magic!

Yay! Let’s dive in—first we’ll whip up a caramel‑infused espresso, then layer on rainbow‑colored foam with a gentle swirl, finish with a sprinkle of glitter. I can’t wait to taste the rainbow!
