Easy Lemon Bars with Graham Cracker Crust
These lemon bars are creamy, tangy, and simple to make. The filling is silky and bright from fresh lemon juice and zest, while the graham cracker crust adds a buttery, slightly sweet foundation. No electric mixer required — everything comes together with a whisk and a few bowls.
Lemon Bars with Graham Cracker Crust and Condensed Milk
Using sweetened condensed milk in the filling creates an extra-smooth texture and pleasant sweetness that balances the tart lemon. The graham cracker crust brings a mild honey-like flavor and crisp texture that complements the creamy topping. If you love lemon desserts, this version is a fresh, easy alternative to shortbread-based lemon squares.
Baked or No-Bake Graham Cracker Crust?
Both methods work depending on the recipe. For these lemon bars, the crust is lightly baked with the filling so it firms up and develops a subtle toasted flavor. For no-bake desserts you can simply press the crust into the pan and chill until set.
Ingredients
Below is a quick overview of the ingredients used in this recipe. See the recipe card for exact amounts and full details.
- Graham cracker crumbs — crushed graham crackers or store-bought crumbs.
- Butter — melted; salted or unsalted with a pinch of salt if needed.
- Brown sugar — adds depth and caramel notes to the crust.
- Cinnamon — optional, a small amount adds warmth to the crust.
- Sweetened condensed milk — gives the filling its creamy, silky texture.
- Fresh lemon juice — use freshly squeezed lemons for the best flavor.
- Lemon zest — enhances the lemon aroma and flavor.
- Egg yolks — room temperature for best mixing.
- Salt — a pinch to balance the flavors.
If you like, finish the bars with fresh whipped cream. For that you’ll need:
- Heavy cream — cold, for whipping.
- Vanilla extract — pure vanilla for the best flavor.
- Powdered sugar — to sweeten the whipped cream and for dusting.

Equipment
Basic tools are all you need: a 9×9 baking pan lined with parchment, mixing bowls, a whisk, and a spatula. If you crush graham crackers at home, a food processor or rolling pin and a resealable bag will make quick work of it. A wire rack helps the bars cool evenly.
Instructions
Here is a concise step-by-step overview. Follow the recipe card for exact measurements and timing.
1. Preheat oven to 325°F. Line a 9×9 pan with parchment paper.
2. Combine graham cracker crumbs, brown sugar, and cinnamon. Stir in melted butter until the mixture holds when pressed. Press evenly into the bottom of the prepared pan.
3. In a large bowl, whisk together sweetened condensed milk, lemon juice and zest, salt, and egg yolks until smooth.
4. Pour the filling over the crust and bake until the filling is just set — it should still be slightly jiggly in the center. About 20 minutes.
Tip: Chill the bars for several hours or overnight before cutting. Top with whipped cream or a dusting of powdered sugar just before serving.
Gluten-Free Option
To make these bars gluten-free, use gluten-free graham crackers or gluten-free vanilla wafers for the crust. Verify any extracts or packaged ingredients are labeled gluten-free.
Meyer Lemon Variation
For a milder, floral lemon flavor, substitute Meyer lemon juice for regular lemons. The rest of the recipe stays the same and yields a softer, less tart filling.
Storage
Store lemon bars in an airtight container in the refrigerator for up to 4 days. You can keep them in the baking pan covered with plastic wrap if preferred. Add whipped cream or powdered sugar just before serving for the best presentation.
FAQ
Make sure the crumbs are fully coated with melted butter and press the mixture firmly and evenly into the pan. If the ratio of butter to crumbs is too low the crust won’t bind properly.
Overbaking can cause cracks. Remove the bars when the edges are set but the center still jiggles slightly — they will continue to set as they cool.
Use a sharp knife and wipe it clean between cuts. For the cleanest slices, chill the bars well before cutting and warm the knife under hot water, drying it before each slice.
Glass is a safe choice because it won’t react with acidic lemon juice. If using a metal pan, line it with parchment to avoid any metallic flavor and ensure easy removal.
Top Tip
Do not overbake. The filling should still be slightly jiggly in the center when you remove the pan from the oven.
Pairing
These lemon bars pair well with light beverages like iced tea, sparkling water, or a simple coffee. They also work nicely alongside fruit-based desserts or a scoop of vanilla ice cream.
