This boozy dessert-in-a-glass is straight out of Willy Wonka’s playbook, but for grown-ups who know their way around a cocktail menu. The first sip hits you with that unmistakable zing of key lime—bright, citrusy, and just tart enough to make your mouth perk up. Then comes the velvety creaminess, smooth and rich like the custard filling of a proper pie. But here’s the kicker: the crust. You taste it. Somehow that buttery graham cracker vibe rolls in at the back like a final note in a perfectly mixed song. The rum’s there too—gentle, golden, and mellow—woven in so seamlessly it just feels like the pie decided to party. Top it off with the whipped cream, and it’s not a garnish—it’s the finale. Every spoonless sip makes you question whether to drink it slow or order another before anyone else notices.
