Ingredients You’ll Need
What makes this 5-Ingredient Lemon Bars With Condensed Milk Recipe so wonderful is how each ingredient plays a crucial role while keeping the list refreshingly short. From the buttery oat biscuit base that provides a nutty crunch to the luscious lemon filling that holds everything together, you’ll love how easy these staples come together for a truly satisfying treat.
- 100 g oat biscuits: These create a wholesome and slightly nutty crust that holds the bars together perfectly.
- 50 g butter (melted): Adds richness and helps bind the biscuit base into a crisp foundation.
- 200 g condensed milk (1/2 a can): Sweet and creamy, this ingredient balances the tartness of lemon for a luscious filling.
- 60 ml lemon juice (from approx. 1.5 lemons): Provides that bright, citrusy zing that makes these bars irresistible.
- 2 eggs (medium): Acts as a natural binder, giving the filling a smooth, custard-like texture.
How to Make 5-Ingredient Lemon Bars With Condensed Milk Recipe
Step 1: Prepare the Base
Start by preheating your oven to 160°C Fan and lining a small baking tray or loaf tin with baking parchment to avoid any sticking. Next, crush the oat biscuits in a large bowl using a rolling pin until they resemble coarse crumbs. Mix in the melted butter thoroughly so every crumb is coated, which will help the base bind when baked. Press this mixture evenly into your tray, making sure to push it firmly into all the corners, creating a sturdy platform for the lemon topping.
Step 2: Bake the Crust
Pop the pressed oat and butter base into the oven for about 10 minutes. This step is essential to ensure the crust firms up nicely before adding the filling, creating a deliciously crisp bottom layer that contrasts beautifully with the creamy top.
Step 3: Make the Lemon Filling
While the crust is baking, whisk together the condensed milk, fresh lemon juice, and eggs using an electric mixer. Whisking for around 2 to 3 minutes not only combines the ingredients fully but also slightly increases the volume for a lighter filling. This creamy lemon mixture is where the magic happens — tangy, sweet, and silky all at once.
Step 4: Assemble and Bake
Once the crust is slightly cooled but still warm, pour the lemon mixture evenly over it. Carefully place the tray back into the oven for about 15 to 20 minutes. You want the filling to set but still retain a bit of that luscious custard softness, so watch for slight firmness without overbaking.
Step 5: Cool and Chill
After baking, allow your lemon bars to cool completely at room temperature. This helps them firm up further. For best results, chill them in the fridge for at least two hours before slicing. This chilling step makes cutting the bars clean and easy, and enhances the flavors as everything melds beautifully together. If you like, dust with icing sugar or sprinkle lemon zest before serving for an extra pop of freshness.
How to Serve 5-Ingredient Lemon Bars With Condensed Milk Recipe
Garnishes
Simple garnishes like a light dusting of icing sugar or tiny curls of lemon zest perfectly complement these bars. The sugar adds a delicate sweetness and a touch of elegance, while the fresh zest adds a boost of citrus aroma that heightens every bite.
Side Dishes
These lemon bars pair wonderfully with a cup of hot tea or freshly brewed coffee for a delightful afternoon pick-me-up. For a fancier dessert setup, serve alongside fresh berries or a dollop of whipped cream to add a creamy texture contrast.
Creative Ways to Present
Try serving the bars on a rustic wooden board or bright ceramic platter to highlight their golden-yellow hue. You can also cut them into petite squares or triangles for charming bite-sized portions at parties. For a fun twist, drizzle a little melted white chocolate or add a sprinkle of toasted coconut on top before chilling.
Make Ahead and Storage
Storing Leftovers
These lemon bars keep beautifully in an airtight container in the refrigerator for up to 4 days. Storing them chilled helps maintain their firm texture and fresh flavor, perfect for enjoying later without losing any of their charm.
Freezing
You can freeze the lemon bars for longer storage by wrapping them tightly in plastic wrap and placing them in a freezer-safe container. Thaw in the refrigerator overnight before serving to keep the texture intact.
Reheating
Because these bars are best served chilled, reheating is usually unnecessary. However, if you prefer them slightly warmed, gently heat for 10-15 seconds in the microwave to soften the filling without melting the crust.
FAQs
Can I use a different type of biscuit for the base?
Absolutely! While oat biscuits give a lovely texture, you can experiment with digestive biscuits or graham crackers for a slightly different flavor and crunch. Just make sure to crush them finely and adjust the butter quantity if needed to ensure a good bind.
What if I don’t have condensed milk on hand?
You could try making your own condensed milk substitute by simmering milk and sugar until thick, but it’s not quite the same. For best results, stick with sweetened condensed milk to achieve that perfect creamy sweetness.
How tart will these lemon bars be?
These bars have a gentle, balanced tartness that comes from fresh lemon juice, mellowed by the condensed milk’s sweetness. If you prefer a more intense lemon flavor, you could add a little lemon zest into the filling before baking.
Can I make this recipe vegan or dairy-free?
This particular recipe relies on condensed milk and butter for its texture and richness, which are dairy-based. For a vegan version, you would need to use plant-based substitutes for butter and a sweetened condensed coconut milk alternative, but the texture and flavor may vary.
How do I get clean slices for serving?
After chilling the bars well in the refrigerator, use a sharp knife warmed under hot water and dried before slicing to get neat, clean cuts. Wiping the knife between cuts also helps maintain tidy edges.

This 5-Ingredient Lemon Bars With Condensed Milk Recipe is one of those rare gems that feels wonderfully indulgent while being incredibly easy to pull together.

- Yield: 8 servings
Ingredients
Crust
- 100 g oat biscuits
- 50 g butter, melted
Filling
- 200 g condensed milk (about 1/2 a can)
- 60 ml lemon juice (from approx. 1.5 lemons)
- 2 medium eggs
Instructions
- Preheat oven: Preheat your oven to 160°C (fan). Line a small baking tray or a loaf tin with baking parchment to prevent sticking.
- Prepare the crust: Crush the oat biscuits using the end of a rolling pin until finely ground. In a large mixing bowl, combine the crushed biscuits with the melted butter until the mixture is evenly mixed. Transfer this crumb mix to the prepared tin and press it down firmly using the back of a spoon, making sure it spreads evenly into all corners. Bake for 10 minutes to set the base.
- Make the filling: While the base is baking, whisk together the condensed milk, lemon juice, and eggs using an electric whisk. Whisk for about 2-3 minutes until the mixture is fully combined and slightly frothy, which helps give the filling a light texture.
- Bake the lemon bars: Pour the lemon filling evenly over the baked oat crust. Return the tray to the oven and bake for 15-20 minutes, or until the lemon filling sets and is firm to the touch.
- Cool and chill: Allow the lemon bars to cool completely at room temperature once removed from the oven. Then, transfer to the fridge and chill for at least 2 hours to fully set and develop flavor.
- Serve: Slice the lemon bars into squares. Optionally, dust with icing sugar and garnish with lemon zest before serving for an elegant finish.
Notes
- Using fan oven helps even and consistent baking but standard oven at 180°C works as well.
- For best results, ensure the filling is not overbaked to avoid cracking.
- You can adjust lemon juice amount slightly to your preferred tartness.
