Key Ingredients & Substitutions
Graham Cracker Crumbs: These are essential for that classic crust. If you can’t find them, you can use crushed digestive biscuits or vanilla wafer cookies for a different flavor profile.
Unsalted Butter: This gives richness to the crust. If you’re looking for a dairy-free option, you can substitute with coconut oil or a dairy-free butter alternative. Just make sure it’s melted!
Sweetened Condensed Milk: This ingredient gives creaminess and sweetness to the filling. For a lighter option, try using low-fat sweetened condensed milk, or mix equal parts almond milk and maple syrup for a vegan alternative.
Key Lime Juice: Freshly squeezed juice is the best choice for flavor. If key limes are hard to find, use regular limes instead for a more common citrus flavor.
Egg Yolks: These add richness and help set the filling. For a vegan version, you can use silken tofu blended until smooth. It won’t taste the same but will give a creamy texture.
How Do You Achieve a Perfectly Baked Filling?
Getting the filling just right can be tricky, but here are some tips to help you succeed:
- Whisk the filling ingredients together until it’s completely smooth; this avoids a grainy texture.
- Keep an eye on the baking time. You want the edges to look set but just a little jiggle in the center. This indicates it will firm up as it cools.
- Let the bars cool at room temperature before chilling in the fridge. This prevents condensation and keeps the texture creamy.

How Much Time Will You Need?
This delightful recipe takes about 15 minutes of prep time and approximately 2 hours of chilling time. You’ll be baking for about 25-30 minutes in total, but most of the time is just waiting for your delicious bars to cool. You’ll love the refreshing taste of these key lime pie bars!
Step-by-Step Instructions:
1. Prepare The Oven and Dish:
Start by preheating your oven to 350°F (175°C). To make it easy to lift the bars out later, line an 8×8 inch baking dish with parchment paper, leaving some paper hanging over the edges.
2. Make The Crust:
In a mixing bowl, mix the graham cracker crumbs, melted butter, and granulated sugar together. Stir until everything is combined well. Press this mixture firmly into the bottom of your prepared baking dish to form a nice, even layer. Bake in the oven for about 8-10 minutes, until it’s lightly golden. When done, take it out and let it cool for a bit.
3. Prepare The Filling:
While your crust is cooling, grab another bowl. Whisk together the sweetened condensed milk, key lime juice, lime zest, and the egg yolks. Make sure it’s all mixed together smoothly—this will be your filling.
4. Bake The Filling:
Pour the filling over your cooled crust, making sure it spreads evenly. Bake in the oven for an additional 15-20 minutes, or until the filling is set and the edges look slightly puffed. Once it’s done, take it out and let it cool to room temperature.
5. Chill and Cut:
After cooling, put your baking dish in the fridge for at least 2 hours to fully chill and set. When ready, carefully lift the dessert out of the pan using the parchment paper. Cut into bars of your desired size.
6. Serve:
Before serving, top each bar with a dollop of whipped cream and a sprinkle of lime zest for that extra pop of flavor. Enjoy your delicious Key Lime Pie Bars!
Can I Use a Different Type of Crust?
Absolutely! If you prefer, you can substitute graham cracker crumbs with crushed vanilla wafers or digestive biscuits for a different flavor. Just make sure to keep the same measurement to maintain the integrity of the crust.
Can I Substitute Fresh Lime Juice with Bottled Juice?
While fresh key lime juice is recommended for the best flavor, you can use bottled key lime juice in a pinch. Just ensure it’s 100% juice without added sugars for a more authentic taste.
How to Store Leftover Key Lime Pie Bars?
Store any leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, you can wrap individual bars in plastic wrap and freeze them for up to 2 months. Just thaw in the fridge overnight before serving!
Can I Make These Bars Ahead of Time?
Yes! Key Lime Pie Bars are perfect for making ahead. You can prepare them a day or two in advance and refrigerate them until you’re ready to serve. Just add the whipped cream and lime zest just before serving for optimal freshness!
