Lemon Cheesecake Bars with a Buttery Graham Cracker Crust
Lemon cheesecake bars give you all the tangy silkiness of a full cheesecake but without a water bath or any tricky unmolding. They bake in a simple square pan and slice into neat, shareable squares.
A buttery graham cracker base balances the bright lemon filling, and after a few hours in the fridge the bars set up into creamy, dense slices you can eat out of hand.
What Makes These Lemon Cheesecake Bars So Good
The lemon flavor comes from both fresh juice and zest, so it tastes bright and real, not like candy. A little sour cream in the filling keeps the texture soft without making it heavy.
Baking in bars means every piece has the same ratio of crisp crust to tangy filling. You skip the springform pan and the worry about cracks, and you can feed a crowd without slicing a whole cake.
Ingredients
- 1 ½ cups graham cracker crumbs: from about 12 full sheets
- ¼ cup granulated sugar: for a lightly sweet crust
- 6 tbsp unsalted butter, melted: plus a little extra for greasing the pan
- 16 oz full-fat cream cheese, softened: block style, not the tub
- ½ cup granulated sugar: plus 1 tablespoon for the filling
- 2 large eggs, at room temperature
- ⅓ cup fresh lemon juice: from about 2 lemons
- 2 tsp freshly grated lemon zest
- ½ cup full-fat sour cream
- 1 tsp vanilla extract
- Pinch of fine sea salt
Variations / Substitutions
- Swap the crust: vanilla wafer or shortbread crumbs work just as well, and keep the butter amount the same.
- Make it lime: replace the lemon juice and zest with an equal amount of lime juice and zest for a lime bar version.
- Dairy-free option: use a dairy-free cream cheese block and a thick plant-based sour cream alternative; the texture will be a touch softer but still sliceable.
- Add a swirl: drop a few tablespoons of lemon curd or blueberry jam onto the filling and drag a knife through before baking for a marbled top.

How to Make Lemon Cheesecake Bars
Step 1: Press the Crust
Preheat the oven to 350°F (175°C) and line an 8-inch square baking pan with parchment, letting the ends overhang the sides. Stir together the 1 ½ cups graham crumbs, ¼ cup sugar, and the 6 tablespoons melted butter until every crumb looks damp.
Press the mixture firmly and evenly into the bottom of the pan. Use the bottom of a flat measuring cup to pack it tight so the bars hold together when you slice them.
Step 2: Pre-Bake the Crust
Slide the pan into the oven and bake the crust for 8 minutes, just until it smells toasty and the edges look slightly darker. This step keeps the crust crisp under the creamy filling.
Let it cool on a rack while you make the filling; you do not need to turn off the oven.
Step 3: Beat the Filling
In a large bowl, beat the 16 oz cream cheese with the ½ cup plus 1 tablespoon sugar until it looks smooth and glossy, about 2 minutes on medium speed. Scrape the bowl down once so there are no lumps hiding near the bottom.
Add the 2 eggs one at a time, beating just until each is mixed in. Then beat in the ⅓ cup lemon juice, the 2 teaspoons zest, the ½ cup sour cream, the vanilla, and the salt. Stop mixing once the filling is uniform because overbeating traps air and can make the bars puff and crack.
Step 4: Bake the Bars
Pour the filling over the cooled crust and smooth the top with a spatula. Bake for 25 to 30 minutes, until the edges look set and the center still wobbles just slightly when you nudge the pan.
The bars will finish setting as they cool, so a little jiggle in the middle is exactly what you want. Pull them out before the top starts to brown for the cleanest, creamiest texture.
Step 5: Slice and Serve the Bars
Let the bars cool completely on a rack, then cover and refrigerate for at least 4 hours, or overnight if you have the time. Once they are fully chilled, lift the whole block out using the parchment overhang and set it on a cutting board.
Slice into 9 even squares with a sharp knife, wiping the blade clean between cuts. Serve cold straight from the fridge.
A Few Tips Before You Start
- Room temperature eggs and cream cheese blend more smoothly, so pull them from the fridge about an hour before you start.
- Fresh lemon juice makes a real taste difference here; bottled juice often has a flat, metallic note that can come through in a simple filling.
- The bars need the full chill time to slice neatly. Rushing that step is the most common reason they fall apart.
- If the top browns faster than you want, tent a piece of foil loosely over the pan during the last 5 minutes of baking.
Bake times depend on your pan size.
| Pan Size | Crust Pre-Bake | Filling Bake |
|---|---|---|
| 8-inch square | 8 min | 25–30 min |
| 9-inch square | 8 min | 20–25 min |
Storing Leftover Cheesecake Bars
- Refrigerate: keep bars in an airtight container in the fridge for up to 4 days.
- Freeze: wrap each bar tightly in plastic and freeze for up to 2 months. Thaw overnight in the fridge before serving.
Frequently Asked Questions
Can I use bottled lemon juice?
It works in a pinch, but the bars will taste noticeably less bright; fresh juice gives you that clean, tangy flavor without any off notes.
How do I cut the bars without the filling sticking to the knife?
Run a large chef’s knife under hot water, wipe it dry, and slice while the bars are still cold from the fridge.
Do I need a water bath for cheesecake bars?
No, these bars bake at a moderate temperature without steam, and the sour cream keeps them creamy so you can skip the water bath entirely.
Can I make them gluten-free?
Yes, swap the graham crackers for a certified gluten-free graham-style crumb or finely ground gluten-free shortbread cookies.
Why did my bars crack on top?
Cracks usually come from overmixing the filling, which whips in too much air, or from baking until the center is fully firm. Pull them when the middle still jiggles slightly.
