From the latest Berry Prickly Pear Frappuccino to the Midnight Mint Mocha Frapp, Banana Split Frapp, and beyond, Starbucks never ceases to surprise us with its creative blended drinks. If it’s a shot of energy you’re after, however, and not just a sugar rush, you’ll want to stick to the classics. There are seven varieties in particular that will net you more caffeine than the rest, particularly when ordered in the medium size of grande (who knew!?). In fact, they’ve got more caffeine than a single shot of espresso — that’s 75 milligrams of caffeine! Read on to find out which ones fit the bill.

If you’re a fan of caramel (who isn’t?), the Caramel Light Frappuccino is a must. Made with “buttery caramel syrup” and nonfat milk, it tastes rich and delivers a whopping 90 milligrams of caffeine while clocking in at just 140 calories. Talk about a win-win!

Otherwise, there’s the Caramel Cocoa Cluster Frappuccino, which adds coffee nut syrup and a mocha drizzle to the mix while maintaining the same amount of caffeine.

Searching for an even bigger energy boost? There’s the OG Coffee Frappuccino, the Caffè Vanilla Frappuccino (which mixes roast coffee with vanilla bean powder), and the Cinnamon Dolce Frappuccino, which boasts a healthy dose of cinnamon syrup, all of which come with a major kick, courtesy of 95 milligrams of caffeine.

Chocolate lovers can up the ante even further (and satisfy your sweet tooth, while you’re at it!) by indulging in a Java Chip Frappuccino or the Mocha Frappuccino, both of which boast 110 milligrams of caffeine. Just remember that all that mocha sauce bumps up the calorie count to over 400 for a grande, making these a great treat for a hot summer day, but maybe not the healthiest choice for an everyday indulgence.

All this talk of Frapps has us feeling a little low on energy… BRB!
