You will absolutely adore this recipe because it is a true few ingredient dessert that takes almost no effort. The creamy sweetened condensed milk creates a rich texture that balances the bright tartness beautifully. It is guaranteed to become one of your favorite Lemon Desserts to share with friends and family.

What to Gather

• 1/2 cup freshly squeezed lemon juice
• 2 cups graham cracker crumbs
• 1/2 cup melted unsalted butter

Creating Your Zesty Treat

• STEP 2 – Mix the graham cracker crumbs and melted butter in a medium bowl until the mixture looks like wet sand.
• STEP 3 – Press the crumb mixture firmly and evenly into the bottom of your prepared baking dish.
• STEP 4 – Whisk the sweetened condensed milk and fresh lemon juice together in a separate bowl until it becomes thick and creamy.
• STEP 5 – Pour the lemon filling over your crust and refrigerate the slice for at least three hours before cutting.

Ways to Enjoy and Customize

• Serve a cold slice alongside some delicious lemon cheesecake fat bombs for a fun party platter.
• Sprinkle toasted coconut flakes over the top if you love the flavor of keto lemon coconut macaroons.
• Swap the graham crackers for an almond flour base to create an allulose-based lemon tart inspired crust.
• Add a generous scoop of dairy free keto lemon mousse with coconut cream right on top for extra decadence.

Pro Tips

• Roll your lemons firmly on the countertop before slicing them to extract the maximum amount of juice.
• Use the flat bottom of a glass or measuring cup to press your crumb crust down tightly.
• Let the filling sit in the bowl for five minutes after whisking so the natural acid can properly thicken the milk.
• Always slice this dessert while it is completely cold for the cleanest cuts.
• Wipe your knife with a warm and damp paper towel between each slice for a beautiful presentation.

FAQs

How should I handle the storage of this slice? Keep your leftover slices in an airtight container in the refrigerator for up to five days. They hold their shape perfectly when kept nice and cold.

What are some easy substitutions for the crust? You can use crushed digestive biscuits or vanilla wafers instead of graham crackers. If you want a gluten free option, a simple almond flour crust works wonderfully.

How do you recommend serving this treat? I prefer serving it chilled directly from the fridge on a warm afternoon. A light dusting of powdered sugar or a dollop of freshly whipped cream makes it extra special.

Why did my lemon filling turn out runny? A common mistake is using bottled juice instead of fresh citrus. The natural acidity in fresh lemons is absolutely required to properly thicken the condensed milk.

Can I freeze this dessert for later? Yes, this slice freezes beautifully if you wrap individual pieces in plastic wrap. Simply let them thaw in the refrigerator for a few hours before you are ready to eat.

Ingredients

  

Graham Cracker Crust

• 2 cups graham cracker crumbs finely crushed
• 1/2 cup unsalted butter melted

Creamy Lemon Filling

• 1 can (14 ounces) sweetened condensed milk
• 1/2 cup fresh lemon juice freshly squeezed

Optional Toppings

• 2 tablespoons toasted coconut flakes optional, for sprinkling
• 2 tablespoons powdered sugar optional, for dusting
• 1/2 cup whipped cream optional, for serving

Equipment

• 8 x 8-inch Square Baking Dish
• Parchment paper
• Mixing bowls
• Whisk
• Silicone Spatula
• Measuring Cups
• Measuring Spoons
• Flat-Bottomed Glass or Measuring Cup
• Sharp Knife

Method

 

1. Line an 8 x 8-inch square baking dish with parchment paper, leaving enough overhang on the sides to lift out the chilled slice easily.
2. Place the graham cracker crumbs in a medium bowl and add the melted unsalted butter. Mix until the crumbs are evenly coated and resemble wet sand.
3. Transfer the crumb mixture to the prepared dish. Press it firmly and evenly into the bottom using the flat bottom of a glass or measuring cup to create a compact crust.
4. In a separate bowl, whisk the sweetened condensed milk and freshly squeezed lemon juice until smooth and thickened. Let the mixture stand for about 5 minutes to allow the lemon juice’s acidity to help thicken the filling.
5. Pour the lemon filling over the prepared crust and gently spread it into an even layer with a spatula.
6. Cover the dish and refrigerate for at least 3 hours, or until the filling is firm enough to slice cleanly.
7. Lift the chilled slice from the dish using the parchment overhang. Cut into 16 squares with a sharp knife, wiping the blade with a warm, damp paper towel between cuts. If desired, sprinkle with toasted coconut flakes or powdered sugar, or serve with a dollop of whipped cream.

Notes

Roll lemons firmly on the countertop before cutting and juicing to help release more juice. Fresh lemon juice is important because its acidity helps thicken the sweetened condensed milk. Bottled juice may not provide the same flavor or results.

Press the crumb crust firmly into the dish to help it hold together when sliced. Allow the filling to rest for about 5 minutes after whisking, then refrigerate the slice for at least 3 hours. For the cleanest cuts, make sure it is completely cold and wipe the knife between slices.

Store leftovers in an airtight container in the refrigerator for up to 5 days. To freeze, wrap individual slices securely and freeze for up to 2 months. Thaw in the refrigerator before serving.

Crushed digestive biscuits or vanilla wafers can replace graham crackers. For a different crust, use a suitable almond flour base. Optional toppings include toasted coconut flakes, powdered sugar, fresh whipped cream, or fresh berries.
