Key Lime Bars
Key Lime Bars have a sweet cookie crust, a zesty yet creamy lime filling, and are topped with toasted coconut. Perfect for parties and BBQs!
In April, my dad gave my sister and I a surprise gift – the Complete America’s Test Kitchen Cookbook TV Show Cookbook! I was so surprised and excited to start using this cookbook. My dad loves watching America’s Test Kitchen and telling us about their recipes. Unfortunately, between wrapping up work and moving, I was only able to bookmark the recipes I wanted to try first and dream about making them.
I decided my first recipe would be something I knew my dad would LOVE – Key Lime Bars! I finally got to make them for a barbecue at my parents’ house Memorial Day weekend.
These bars are so delicious and perfect for summer! The have a prominent lime flavor that is nicely balanced by the sweetness of the cookie crust. I like the crunchiness of the toasted coconut on top, although some of my family members who don’t like coconut chose to have their bars without it.
The original recipe makes an 8 x 8-inch pan but states it can be easily doubled and made in a 13 x 9-inch pan. Since I made a double batch, I’ve provided the recipe for it below. If you make the single batch, just shave a few minutes off the baking time.

Key Lime Bars
For the Crust:
- 10 ounces animal crackers
- 6 tablespoons brown sugar
- 2 pinches of table salt
- 8 tablespoons butter, melted and cooled slightly (1 stick)
For the Filling:
- 4 ounces cream cheese (at room temperature)
- 2 tablespoons grated zest from 2 limes
- 2 pinches of table salt
- 28 ounces sweetened condensed milk (two 14-ounce cans)
- 2 large egg yolks
- 1 cup fresh lime juice (from about 40 Key limes or about 6-8 Persian limes)
- 1 1/2 cups sweetened shredded coconut (toasted until golden and crisp)
- Adjust an oven rack to the middle position and heat the oven to 325 degrees F.
- Line a 13 x 9-inch baking pan with a double layer of foil, placed so that the foil extends beyond the sides of the pan to help lift the bars out when finished. Spray foil with vegetable oil spray.
Make the Crust:
- Pulse the animal crackers in a food processor until broken down, about 10 pulses; process the crumbs until evenly fine, about 10 seconds. You should have about 1 1/4 cups crumbs.
- Add the brown sugar and salt; process to combine, 10 to 12 pulses. If large lumps of sugar remain, break them apart with your fingers.
- Drizzle the butter over the crumbs and pulse until the crumbs are evenly moistened with the butter, about 10 pulses.
- Press the crumbs evenly and firmly into the bottom of the prepared pan. Bake until deep golden brown, 18 to 20 minutes. Cool on a wire rack while making the filling. Do not turn the oven off.
Make the Filling:
- While the crust cools, in a medium bowl, stir together the cream cheese, zest, and salt with a rubber spatula until softened, creamy, and thoroughly combined. Alternatively, use the bowl of a stand mixer and the whisk attachment.
- Add the sweetened condensed milk and whisk vigorously until incorporated and no lumps of cream cheese remain; whisk in the egg yolks. Add the lime juice and whisk gently until incorporated. The mixture will thicken slightly.
Assemble and Bake:
- Pour the filling into the crust; spread to the corners and smooth the surface with a rubber spatula. Bake until set and the edges begin to pull away slightly from the sides, 15 to 20 minutes.
- Cool on a wire rack to room temperature, 1 to 1 1/2 hours. Cover with foil and refrigerate until thoroughly chilled, at least 2 hours.
- Loosen the edges with a paring knife and lift the bars from the pan using the foil extensions; cut the bars into squares. Sprinkle with the toasted coconut and serve.
