Flaky golden pastry filled with creamy cheesecake and kissed with the tart brightness of fresh key lime—it’s the kind of dessert that makes you close your eyes and smile after the very first bite. Key Lime Cheesecake Pastries strike the perfect balance between indulgence and freshness. Trust me, you’re going to love this one—it’s zesty, creamy, and worth every bite.

Behind the Recipe

This recipe was inspired by a beachside vacation where every bakery window seemed to show off something citrusy and refreshing. Key lime pie was everywhere, but I wanted to capture that same tropical tang in a fun, handheld pastry. Think of it as a love letter to that perfect combination of buttery pastry and tangy-sweet cheesecake filling, designed for moments when you want a treat that feels a little playful and a lot delicious.

Recipe Origin or Trivia

Key limes, also known as Mexican limes, are smaller, more aromatic, and more tart than their common Persian lime cousins. They’re famous for being the star of the Florida Keys’ most iconic dessert, Key Lime Pie. By pairing this citrus gem with cheesecake and flaky puff pastry, we’re merging classic American baking traditions with a French-style pastry twist, creating a hybrid dessert that feels both familiar and excitingly new.
