What is a No Bake Lemon Slice?
A no bake lemon slice is a classic dessert that’s especially popular in Australia, New Zealand, and the UK. It typically consists of a biscuit or graham cracker base, combined with condensed milk, lemon juice, and coconut. The mixture is pressed into a tray, chilled until firm, and then topped with a simple lemon icing before slicing into squares or bars.
This dessert is loved not only for its bright and zesty flavor but also for its ease of preparation. Since it doesn’t require baking, it’s perfect for busy households or hot days when you want to avoid using the oven. The ingredients are affordable, the prep time is minimal, and the results are deliciously rewarding.
Key Ingredients
Each no bake lemon slice recipe may vary slightly, but most versions use the following key ingredients:
- Crushed biscuits or cookies: Often digestive biscuits, graham crackers, or vanilla wafers are used as the base.
- Sweetened condensed milk: Adds creaminess and sweetness to hold the base together.
- Desiccated coconut: Brings a chewy texture and complements the lemon flavor.
- Lemon juice and zest: Fresh lemon gives the dessert its signature tartness and bright citrus aroma.
- Butter: Melted butter binds the dry ingredients and enriches the base.
For the topping, most recipes use a simple icing made from powdered sugar, lemon juice, and sometimes a little melted butter to create a smooth, glossy finish that hardens as it chills.
Step-by-Step Preparation
1. Prepare the Base
Start by crushing your biscuits or cookies into fine crumbs. You can do this by placing them in a zip-lock bag and crushing with a rolling pin, or by pulsing in a food processor. In a large mixing bowl, combine the crumbs with desiccated coconut and lemon zest. In a separate bowl, mix the sweetened condensed milk with melted butter and lemon juice. Pour the wet mixture over the dry ingredients and mix well until combined.
Press the mixture firmly into a lined square or rectangular tray. Use the back of a spoon or spatula to smooth out the surface evenly.
2. Make the Lemon Icing
To make the icing, mix powdered sugar with freshly squeezed lemon juice. If desired, add a little melted butter to enhance the texture and flavor. Stir until the icing is smooth and pourable. Spread the icing evenly over the base layer.
3. Chill and Slice
Place the tray in the refrigerator and chill for at least 2-3 hours or until the slice is firm. Once set, remove from the tray and cut into squares or bars. Store the slices in an airtight container in the fridge.
Flavor Variations
One of the great things about no bake lemon slice is how easy it is to customize. Here are a few popular variations:
- Lime or orange slice: Swap out lemon juice for lime or orange for a different citrus twist.
- Add white chocolate: Stir in white chocolate chips or drizzle melted white chocolate on top for extra richness.
- Use flavored biscuits: Try using ginger snaps or lemon-flavored cookies for added depth.
- Top with coconut flakes: Sprinkle shredded coconut over the icing before chilling.
These variations still preserve the dessert’s simplicity while offering new and exciting flavor combinations.
Why No Bake Lemon Slice is Perfect Year-Round
While this dessert is especially popular during spring and summer, it’s actually ideal any time of the year. It stores well in the fridge, making it a great make-ahead treat for parties, family gatherings, or lunchbox snacks. Because it doesn’t rely on seasonal fruit, you can make it whenever the craving strikes. Its light, refreshing flavor also makes it a welcome change from heavier baked goods during the colder months.
Tips for the Best No Bake Lemon Slice
To ensure your lemon slice turns out perfect every time, keep these tips in mind:
- Use fresh lemons: Fresh juice and zest provide the best flavor and aroma.
- Don’t skip the zest: It enhances the lemon flavor and adds a lovely fragrance.
- Press the base firmly: This helps the slice hold together and makes cutting easier.
- Chill thoroughly: Give the dessert enough time to set before slicing.
- Use parchment paper: Lining your tray will make it easier to lift out and cut neatly.
Serving Suggestions
No bake lemon slice is best served cold, straight from the fridge. It pairs wonderfully with a cup of tea or a light espresso. For an extra special touch, you can garnish each piece with a tiny curl of lemon zest or a thin lemon wedge. Some even add a dusting of powdered sugar right before serving to enhance its visual appeal.
This dessert also works beautifully as part of a dessert platter, alongside other no bake treats like chocolate truffles, mini cheesecakes, or fruit tarts. Its bright color and tangy taste help it stand out among richer or chocolate-heavy options.
Storage and Shelf Life
Store no bake lemon slice in an airtight container in the refrigerator. It typically keeps well for up to one week. If you want to make it ahead for a later date, you can also freeze it. Simply slice it first, wrap the individual portions in plastic wrap, and place them in a freezer-safe container. Thaw in the fridge before serving.
