Ingredients You’ll Need
For the crust:
- 1 and ½ cups graham cracker crumbs
- 6 tablespoons unsalted butter, melted
- 3 tablespoons granulated sugar
- Pinch of salt
For the filling:
- 1 can (14 ounces) sweetened condensed milk
- 4 large egg yolks
- ½ cup fresh lime juice (about 4 to 5 limes)
- 1 tablespoon lime zest
- Optional: a drop or two of green food coloring for a more vibrant appearance
Topping (optional):
Powdered sugar for dusting
Whipped cream or lime wedges for serving
Step-by-Step Instructions
Step 1: Preheat your oven to 350 degrees Fahrenheit. Line an 8×8 inch square baking pan with parchment paper or foil, leaving some overhang on the sides for easy removal later.
Step 2: In a mixing bowl, combine the graham cracker crumbs, melted butter, sugar, and salt. Stir until the mixture resembles wet sand and holds together when pressed.
Step 3: Press the crust mixture firmly into the bottom of the prepared pan using the back of a spoon or the bottom of a measuring cup. Bake for 10 minutes until lightly golden. Remove from the oven and let it cool slightly while you prepare the filling.
Step 4: In a separate bowl, whisk together the sweetened condensed milk and egg yolks until well blended. Add the lime juice and zest, and whisk again until the mixture is smooth and creamy. If using food coloring, stir it in at this stage.
Step 5: Pour the filling over the partially baked crust and spread evenly. Bake in the preheated oven for 15 to 18 minutes, or until the edges are set and the center jiggles slightly when the pan is gently shaken.
Step 6: Let the bars cool to room temperature, then transfer them to the refrigerator and chill for at least 3 hours, or until fully set. Chilling helps the texture firm up and enhances the flavor.
Step 7: Once set, lift the bars out of the pan using the parchment or foil overhang. Slice into squares or rectangles using a sharp knife. Wipe the knife clean between cuts for neat edges.
Step 8: Dust with powdered sugar just before serving, or add a dollop of whipped cream and a small lime wedge for a decorative touch.
Helpful Tips for Success
Use fresh lime juice, not bottled. Fresh juice delivers the brightness and acidity that defines this dessert.
Make sure to zest the limes before juicing. It’s much easier, and the zest adds a burst of lime flavor that rounds out the filling.
Let the bars chill fully. This is key to achieving a firm, creamy texture. You can even make them a day in advance.
If you prefer a sweeter flavor, reduce the lime juice slightly or add a tablespoon of sugar to the filling.
When pressing the crust, make sure it’s evenly distributed and compacted to avoid crumbling when cutting the bars.
Frequently Asked Questions
Can I use a different crust?
Yes. While graham crackers are classic, you can substitute with vanilla wafers, digestive biscuits, or shortbread cookies for different textures and flavors.
Are these bars the same as key lime pie?
They’re similar but not the same. These bars are slightly thicker and firmer than traditional key lime pie and easier to cut and serve at events or potlucks.
Can I freeze them?
Yes. Once fully chilled and sliced, place the bars in a single layer on a tray to freeze. Once solid, transfer to an airtight container with parchment paper between layers. Thaw in the refrigerator before serving. The texture may soften slightly after freezing, but the flavor remains excellent.
How long can I store them?
They can be refrigerated for up to 4 days. For best results, keep them tightly covered to prevent them from absorbing other flavors from the fridge.
Can I use lemons instead of limes?
Absolutely. You can replace the lime juice and zest with lemon for a lemony version of this dessert. The result will be equally creamy and refreshing with a different citrus twist.
Serving Suggestions
Serve these bars cold, straight from the refrigerator. They’re light enough to be the perfect ending to a rich meal or a refreshing mid-afternoon snack.
Try pairing them with:
Iced herbal tea or lemonade
Fresh berries on the side
A swirl of raspberry coulis for a more elegant presentation
Crushed pistachios or toasted coconut on top for texture
These creamy lime dessert bars are flexible enough to dress up for a dinner party or enjoy as a simple weekday treat.
