Ingredients
Main
| Amount | Ingredient |
| 20 whole | graham crackers |
| 2 cans (28 oz total) | sweetened condensed milk |
| ¾ cup | fresh lemon juice |
How To Make It
[3 min] Line a 9×9 inch pan with parchment paper.
[4 min] Arrange graham crackers in a single layer to fully cover the bottom. Break a few pieces to fill the gaps for a snug fit.
[3 min] Whisk sweetened condensed milk and fresh lemon juice until smooth and slightly thickened. Let the mixture sit for 5 minutes to activate the set.
[2 min] Pour the lemon filling over the graham crackers and smooth the top. Pro Tip: Tilt the pan gently instead of over-spreading to keep the cracker base intact.

[5 min] Cut into squares and serve cold. Add a little lemon zest on top if you want more citrus aroma.

FAQ
Q: Do 3 ingredient no-bake lemon bars really set?
A: Yes, they do set after a proper chill. The acid in the lemon juice reacts with the condensed milk and thickens the filling naturally over time.
Q: Can I use digestive biscuits instead of graham crackers?
A: Yes, digestive biscuits work very well and give the bars a slightly richer, more buttery flavor. Press them in the same way to create a sturdy base.
Q: Why is my lemon filling too runny?
A: Usually the bars need more chill time, or the lemon juice measurement was too low. Fresh lemon juice is important because it provides the acidity needed to thicken the filling.
Q: Can I add cream cheese to this easy lemon bar recipe?
A: Yes. If you want a richer version, beat in 4 to 8 ounces of softened cream cheese. That turns the texture closer to no-bake cheesecake bars.
Q: Are these bars good for parties?
A: Yes, especially when cut into small squares. They travel well in a chilled container and fit nicely on brunch, picnic, and dessert buffet tables.
