Grapefruit Tiramisu

A refreshing twist on classic tiramisu made with grapefruit juice, citrus zest, and rich mascarpone filling. Bright, creamy, and perfect for making ahead.

If you told me years ago that I’d be making grapefruit tiramisu, I probably would’ve laughed. I mean… I know. I hope the Italians won’t yell at me for this 😂 I absolutely love classic tiramisu and can’t stop making it.
This is definitely not a classic tiramisu. It’s inspired by the traditional Italian dessert, but instead of coffee and liqueur, we’re going bright and citrusy with fresh grapefruit juice and zest. And let me tell you — it works. The citrus aroma is so refreshing. Yes, grapefruit has a slight bitterness, but you honestly don’t notice it here. The creamy mascarpone filling balances everything beautifully. It’s lightly sweetened (just how we like it), silky, and luxurious without feeling heavy. This is one of those desserts that tastes fancy but feels fresh and light — perfect after a rich meal.
