Here’s how Starbucks can charge you $23.60 for a cup of coffee:

I’m not sure why you’d try to make Starbucks more expensive, but this guy did it.  22-year-old Logan Warren of Nacogdoches, Texas decided to figure out a combination for the most expensive drink possible at Starbucks.  Here’s what he got:

•  A Java Chip Frappuccino for $4.75 in a 31-ounce Trenta cup.

• 16 shots of espresso for $12 and a shot of soy milk for 60 cents.

• A scoop of banana puree for $1, strawberry puree for 60 cents, protein powder for 50 cents, and Matcha powder for 75 cents.

• Plus caramel flavoring for 50 cents, vanilla beans for 50 cents, and a caramel and mocha drizzle for 60 cents.

Total cost?  $23.60, not including the tip he gave the baristas for taking 20 minutes to make the drink.  Logan actually didn’t even pay for it . . . because he had a coupon for a free birthday drink.

He says the taste was, “Tolerable but not good.  Imagine a coffee-based health food smoothie.”

It also has 1,400 milligrams of caffeine. That’s  so much that if you drank the whole thing, you’d probably end up in the hospital.
