These luscious, creamy lemon bars with graham cracker crust are a dream for citrus lovers. With a texture similar to key lime pie, they take under 30 minutes to prepare and pair a rich, tart lemon layer with a buttery graham cracker crust and a hint of ginger for depth—perfect for parties, potlucks, or a simple weeknight treat.
I’ve never loved classic lemon bars because the lemon filling often feels too firm and the shortbread can be heavy. So I developed these creamy lemon bars that are closer to a key lime pie in texture—silky, smooth, and truly satisfying.
Instead of a traditional shortbread base, these use a graham cracker crust for a lovely crunch and buttery flavor. The lemon layer is custard-like and velvety thanks to sour cream and sweetened condensed milk. The result is bright, tangy, and unmistakably lemony.
Why We Love These Creamy Lemon Bars
If you love all things lemon, these bars are a must-try. They’re a simple dessert packed with citrus flavor and great texture.
Highlights:
- Bright, concentrated lemon flavor
- Great as a summer dessert but lovely year-round
- Only a handful of common ingredients and easy to make
- Freeze well for later
- A texture that’s creamy and custardy rather than cakey
Ingredient Notes
See the full ingredient list with exact measurements in the recipe card below.
- Fresh lemon juice gives the best, brightest flavor—bottled juice won’t compare. You’ll also need the lemons for zest.
- Be sure to use sweetened condensed milk, not evaporated milk. Condensed milk is thick and sweet and is essential for the filling’s texture and sweetness.
- Full-fat sour cream is key to the filling’s silky texture and balanced flavor. It keeps the filling creamy without being overly sweet.
Ways To Vary This Recipe
- Try a different citrus: key lime juice and zest make a delicious variation, or combine lemon and lime for extra complexity.
- Use a shortbread crust: if you prefer a classic base, a shortbread crust will work in place of the graham cracker crust.
- Top with fruit: fresh berries, a fruit sauce, or a dollop of whipped cream make lovely finishing touches.
Step-By-Step Instructions
Step 1: Pulse graham crackers in a food processor until they become fine crumbs.
Step 2: Add melted butter, vanilla, sugar, salt, and a pinch of ground ginger, then pulse until combined.
Step 3: Line a 9×9-inch pan with parchment and press the crust mixture firmly into the bottom in an even layer.
Step 4: Bake the crust for 10 minutes, then let it cool slightly.
Step 5: In a medium bowl combine the sweetened condensed milk, eggs, egg yolks, lemon juice, lemon zest, and sour cream.
Step 6: Whisk until smooth and creamy. Using room-temperature ingredients helps achieve a silky, lump-free filling.
Step 7: Pour the filling over the crust and bake 15–20 minutes, until the edges are set and the center still jiggles slightly.
Step 8: Cool on a rack about 30 minutes, then refrigerate for at least 2 hours (3 hours is best) to fully set. Serve plain, dusted with powdered sugar, or topped with whipped cream.
Recipe Tips
Double-check the milk: use sweetened condensed milk, not evaporated milk—the texture and sweetness depend on it.
Room-temperature ingredients: For the smoothest filling, bring eggs, condensed milk, and sour cream to room temperature before mixing.
Chill time matters: You can eat the bars after cooling, but chilling 2–3 hours yields the best texture and clean slices.
Storage
Store in an airtight container in the refrigerator for up to 5 days. To freeze, cool completely, place bars in a freezer-safe container, and freeze up to 3 months. Thaw in the refrigerator before serving.
Creamy Lemon Bars with Graham Crust
Ingredients
Crust
- 14 sheets graham crackers (about 1 ¾–2 cups crumbs)
- 7 Tbsp unsalted butter, melted, slightly cooled
- ½ tsp vanilla extract
- ¼ cup sugar
- ¼ tsp ground ginger, optional
- ¼ tsp sea salt
Lemon Filling
- 2 14-oz. cans sweetened condensed milk
- 2 large whole eggs, room temperature
- 2 large egg yolks, room temperature
- 1 cup freshly squeezed lemon juice
- 1 Tbsp lemon zest
- ½ cup sour cream, room temperature
Optional Whipped Cream Topping
- ¾ cup heavy whipping cream, very cold
- 2 Tbsp powdered sugar
- ½ tsp vanilla extract
Instructions
-
Preheat oven to 350°F.
-
Prepare the crust: pulse graham crackers to crumbs, then mix in melted butter, vanilla, sugar, salt, and ginger until combined.
-
Press the crust into a parchment-lined 9×9-inch pan, pressing firmly so it holds together. Bake 10 minutes and let cool slightly.
-
Make the filling: whisk all filling ingredients together until smooth. Room-temperature ingredients give the best texture.
-
Pour the filling over the crust and bake 15–20 minutes, until edges are set and the center still jiggles slightly.
-
Cool on a rack for 30 minutes, then chill in the refrigerator for at least 2 hours, preferably 3.
-
To serve: whip the cream with powdered sugar and vanilla until stiff peaks form, then dollop or pipe on slices and garnish with a lemon wedge.
Notes
Use sweetened condensed milk: evaporated milk won’t produce the same texture or sweetness.
Room temperature ingredients: allow eggs, condensed milk, and sour cream to reach room temperature for a smooth filling.
Chill before slicing: chilling helps the bars set and makes cleaner slices.
