Key Lime Dessert Bars

Jump to Recipe

Growing up in Chicago, my love for sweet treats was nurtured in my family’s bustling kitchen. My babcia, with her Polish roots, was the queen of baking, and I fondly remember the aroma of freshly baked apple cake wafting through the house. But it was during one of our summer trips to Florida that I discovered the magic of Key Lime Dessert Bars. The tangy, refreshing flavor was a revelation, and I knew I had to bring a piece of that sunshine back home. Over the years, I’ve perfected this recipe, adding a touch of my own flair while keeping it simple enough to whip up on a lazy Sunday afternoon. These bars have become a family favorite, often requested by my kids, Ella and Peter, especially when we need a little pick-me-up during the long Chicago winters.

Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until the crumbs are well coated.
  3. Press the mixture firmly into the bottom of the prepared baking dish to form an even crust. Bake for 10 minutes or until lightly golden. Remove from the oven and let it cool slightly.
  4. In another bowl, whisk together the sweetened condensed milk, key lime juice, lime zest, egg yolks, and salt until smooth and well combined.
  5. Pour the lime filling over the baked crust, spreading it evenly with a spatula.
  6. Bake for 15-20 minutes, or until the filling is set but still slightly jiggly in the center.
  7. Allow the bars to cool to room temperature, then refrigerate for at least 2 hours before slicing and serving.
