I have tried for literally years to perfect the art of making a Mocha Latte! Until yesterday, I discovered how to make one with only three ingredients and it tastes delicious! It still isn't Coffee Bean good (I have this joke that I want to work there for like a day so I can figure out how they make theirs and then quit and just make it for myself, shh don't tell ;), but to warm me up for the winter, it's great!
The main component of this is a mocha powder. I know that sounds really obvious but I thought I'd be able to get it right with some coffee and chocolate. Compared to this, boy!, was I wrong. I recently got this Maxwell House: International Cafe Suisse Mocha Powder from the grocery store. This is the only powder I've tried but I saw others there as well so keep your options open! One of the main reasons I got this was also that is decaf which is good for when I want a hot drink before bed.
