Take your regular chocolate milkshake to the next level with a sinfully good recipe that features the classic flavor combination of chocolate and peanut butter. Homemade hot fudge and peanut butter sauces swirled together create a rich, creamy shake with pockets of peanut butter and chocolate, which give it a malt-like texture. Garnish with a miniature Reese’s peanut butter cup—or two. Indulge yourself, but eat slowly. Take it from us: You’ll need every bit of willpower not to consume seconds or thirds (or fourths).
