Key Lime Pie Jars

There’s a certain charm to desserts served in jars—layered, portable, and perfectly portioned. But when you take the bright, zesty tang of key lime pie and stack it in a glass with a buttery graham crust and a silky whipped topping, magic happens. These Key Lime Pie Jars are refreshing, creamy, and satisfyingly crunchy in all the right ways. Each spoonful is like a trip to the tropics, wrapped in convenience and charm.

Behind the Recipe

The first time I made key lime pie jars, it was for a picnic in the park. I wanted something cool and citrusy, but also easy to transport and share. Inspired by the classic pie but aiming for a fuss-free format, these little jars came to life. They quickly became a go-to for potlucks, dinner parties, and “just because” treats. There’s something joyful about serving dessert with a lid.

Recipe Origin or Trivia

Key lime pie originates from the Florida Keys, where small, aromatic key limes grow in abundance. Traditionally, the pie was made without baking, relying on the chemical reaction between the acidic lime juice and sweetened condensed milk to “cook” the filling. Over time, whipped toppings and crusts evolved, and now the dessert is a celebrated American classic. Our jar version gives it a modern twist without losing its sunny roots.
