Prep Time, Cook Time, and Servings
Prep time: 20 minutes
Chill time: 2 hours
Total time: 2 hours and 20 minutes
Servings: 12 bars
Ingredients
- 1 ½ cups crushed digestive biscuits
- ½ cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- ¾ cup fresh lemon juice (about 4 lemons)
- 1 tablespoon lemon zest
- 2 tablespoons cornstarch
- ¼ teaspoon salt

Instructions
- In a mixing bowl, combine the crushed digestive biscuits and melted butter. Mix well until all the crumbs are coated.
- Press the mixture firmly into the bottom of a greased 9×9 inch baking dish to form the crust. Place it in the fridge to set while you prepare the filling.
- In a large bowl, whisk together the granulated sugar, eggs, lemon juice, lemon zest, cornstarch, and salt until smooth.
- Pour the lemon mixture over the chilled biscuit crust, spreading it evenly.
- Return the baking dish to the refrigerator and chill until set, approximately 2 hours.
- Once set, cut into squares and serve chilled for the best flavor.
Pro Tips for Perfect Results
- For a stronger lemon flavor, add an extra tablespoon of lemon zest to the filling.
- Make sure to pack the biscuit crust tightly to ensure it holds together well when cut.
- Use fresh lemon juice for the best tangy flavor; bottled juice won’t have the same freshness.
- Allow the bars to chill thoroughly before cutting, as this helps them firm up for cleaner edges.
- Experiment with different cookie bases, such as graham crackers, for a unique twist!
Variations and Substitutions
- For a healthier version, use whole grain digestive biscuits instead of regular ones.
- To reduce sugar, substitute half the granulated sugar with a sugar alternative like stevia.
- Add some fresh berries on top before serving for a colorful and nutrient-rich twist.
Storage and Reheating Tips
No-Bake Lemon Bars can be stored in an airtight container in the refrigerator for up to 5 days.
For longer storage, these bars can be frozen for up to 3 months. Just make sure to wrap them tightly in plastic wrap and then place them in a freezer-safe container. Thaw in the refrigerator overnight before serving. There’s no need to reheat these treats; they are delicious straight from the fridge!
FAQ
Can I use bottled lemon juice?
While bottled lemon juice can be used in a pinch, fresh lemon juice gives a much brighter and tangier flavor that enhances the overall taste of the bars.
How can I ensure my bars are set properly?
Be patient and allow the bars to chill for at least 2 hours. If they still feel soft after this time, leave them in the fridge a bit longer until set.
Can I double the recipe?
Yes! Just use a larger baking dish, and be sure to increase the chilling time as needed since a thicker layer will take longer to set.
What can I use instead of digestive biscuits?
Graham crackers or vanilla wafer cookies can be great substitutes for the crust if you want a different flavor profile.
Are No-Bake Lemon Bars gluten-free?
To make these gluten-free, simply use gluten-free biscuits instead of digestive biscuits, and ensure all ingredients are certified gluten-free.
