The first time I made this for my wife, she called her mother. Australian Lamingtons — squares of soft sponge cake dipped in chocolate icing and rolled in desiccated coconut — are one of those deceptively simple confections that somehow produce something greater than the sum of their parts. The sponge is light, the chocolate coating is sweet without being cloying, and the coconut provides both texture and a slight savory-sweet counterpoint that makes you reach for another one before finishing the first.
Lamingtons are Australia’s unofficial national dessert, traditionally made for school fundraisers, bake sales, and afternoon tea. They have a reputation for being fussy, but that reputation is undeserved. The sponge cake is a standard genoise. The chocolate icing is a simple ganache or icing sugar mixture. The assembly is methodical but not difficult. What you need is patience and a cake that’s a day old — fresh sponge crumbles when dipped; day-old sponge holds together with integrity.
Make the sponge the day before. Dip and coat the next day. Your patience will be rewarded with something that tastes genuinely special and looks professionally made.
Why These Australian Lamingtons Work
- Day-old sponge: Fresh sponge is too fragile for dipping. A night in the refrigerator firms the texture just enough to survive the chocolate dipping process without crumbling apart.
- Thin chocolate icing: The icing should be thin enough to coat smoothly and dry quickly. Thick icing clumps and pools at the edges. A fluid icing that drips off easily is the goal.
- Desiccated coconut: Fine desiccated coconut (unsweetened) adheres better and produces a more refined-looking lamington than coarser coconut. The texture is an important part of the eating experience.
- Two-fork dipping method: Using two forks to dip and lift the sponge squares keeps your hands clean and gives you control over the coating without squeezing or manhandling the delicate cake.
Ingredients
For the Sponge Cake
- 4 large eggs, at room temperature
- ¾ cup caster sugar (or fine white sugar)
- 1 cup all-purpose flour
- 2 tbsp cornstarch
- 1½ tsp baking powder
- ¼ tsp salt
- 2 tbsp unsalted butter, melted and cooled
- 2 tbsp whole milk
- 1 tsp vanilla extract
For the Chocolate Icing
- 3 cups powdered sugar
- ¾ cup unsweetened cocoa powder
- ½ cup whole milk (plus more as needed)
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
For Coating
- 3 cups desiccated coconut (unsweetened, fine)
Instructions
Step 1: Make the Sponge Cake
Preheat oven to 350°F. Grease and line an 8×8-inch or 9×9-inch square baking pan. Using an electric mixer, beat eggs and sugar on high speed for 5–6 minutes until the mixture is very pale, thick, and has tripled in volume. The batter should fall in thick ribbons when the beaters are lifted. Sift flour, cornstarch, baking powder, and salt together. Gently fold the flour mixture into the egg mixture in three additions using a large spatula — fold, do not stir. Fold in melted butter, milk, and vanilla. Pour into prepared pan. Bake 25–30 minutes until a toothpick comes out clean and the surface springs back when lightly pressed. Cool completely, then refrigerate overnight.
Step 2: Cut the Sponge
Remove cold sponge from the refrigerator. Trim the edges (optional but gives cleaner lamingtons). Cut into 16 equal squares — approximately 1½ inches per side. Place on a baking sheet lined with parchment. Return to the fridge until ready to dip. Cold sponge is firmer and easier to work with.
Step 3: Make the Chocolate Icing
Combine powdered sugar and cocoa powder in a large heatproof bowl. Melt butter in the milk over low heat or in the microwave. Pour warm milk-butter mixture and vanilla into the cocoa-sugar mixture. Stir until completely smooth. The icing should be fluid — thin enough to flow off a spoon readily. If too thick, add milk 1 tbsp at a time. Keep the icing bowl warm by setting it over a bowl of hot water — it thickens as it cools and needs to stay fluid during the dipping process.
Step 4: Dip and Coat
Set up an assembly line: chocolate icing in a deep bowl, desiccated coconut in a shallow tray, and a wire rack over parchment to receive finished lamingtons. Using two forks, lower a sponge square into the chocolate icing. Turn to coat all sides completely. Lift, let excess drip off for 5–10 seconds, then immediately drop into the coconut tray. Use the forks to gently press coconut onto all sides. Transfer to the wire rack. Repeat with all squares. Work quickly — the icing sets as it cools.
Step 5: Set and Serve
Allow lamingtons to set at room temperature for 1–2 hours. The chocolate coating will firm and the coconut will adhere permanently. They’re ready when the coating is set and no longer tacky. Serve at room temperature. Do not refrigerate after coating — refrigeration dries out the coconut.
Tips & Common Mistakes
- Day-old sponge is mandatory: Fresh sponge crumbles during dipping. The overnight rest in the fridge firms the texture and makes successful dipping possible. Don’t attempt to shortcut this step.
- Keep the icing warm and fluid: The icing thickens as it cools. Keep the bowl over warm water throughout the dipping process. If it thickens too much, add warm milk one teaspoon at a time and stir to restore fluidity.
- Work in an assembly line: Dip → drip → coconut → rack. Having everything set up before starting makes the process smooth. Stopping to reorganize in the middle results in lumpy, uneven lamingtons.
- Don’t overfold the sponge batter: The folding motion must preserve the air beaten into the eggs. Stirring instead of folding collapses the batter and produces a dense, heavy sponge instead of the light, airy one needed.
Variations
- Jam and cream lamingtons: Split each lamington horizontally after the coating sets and fill with raspberry jam and whipped cream. The filled version is considered by many Australians to be superior to the original.
- White chocolate lamingtons: Replace cocoa in the icing with melted white chocolate thinned with cream. Coat in pink-tinted coconut for a visual variation.
- Mini lamingtons: Cut sponge into smaller 1-inch cubes for bite-sized party treats. Dip and coat the same way. Reduce setting time slightly as the smaller pieces set faster.
- Strawberry lamingtons: Replace milk in the icing with strawberry juice or blended strawberries. Produces a pink icing with fresh berry flavor.
For more memorable desserts from around the world and at home: Jamaican jerk chicken for the savory side, and Southern peach cobbler, apple crisp, strawberry shortcake, and homemade cinnamon rolls for the sweet side.
Storage & Reheating
- Room temperature: Store in an airtight container at room temperature for up to 3 days. The lamingtons are best on day 1 and day 2.
- Refrigerator: Not recommended after coating — refrigeration dries out the coconut and makes the sponge slightly rubbery. Room temperature is correct for finished lamingtons.
- Freezing: Uncoated sponge squares freeze well for up to 2 months. Freeze on a tray, then transfer to a bag. Thaw overnight in the fridge and coat from cold — frozen sponge is actually ideal for dipping.
- Uncoated sponge: The plain sponge keeps covered at room temperature for 2 days or refrigerated for 3 days before coating.
Frequently Asked Questions
What is desiccated coconut?
Desiccated coconut is dried, shredded coconut with most of its moisture removed, resulting in a fine, dry texture different from the moist shredded coconut common in American baking. It adheres better and produces a cleaner coating. Available at most grocery stores in the baking aisle or at specialty stores. Unsweetened desiccated coconut is correct for this recipe.
Can I use a boxed sponge or white cake mix?
Yes, as a shortcut — bake the cake according to package directions, cool completely, refrigerate overnight, and then proceed with the dipping and coating steps. A homemade genoise sponge has a lighter texture, but boxed cake produces perfectly good lamingtons that taste like the real thing.
Why does my sponge fall apart when I dip it?
The sponge is either too fresh (needs overnight refrigeration to firm up) or the icing is too thick (which requires forceful pressing that breaks the cake). Make sure sponge is thoroughly chilled and the icing flows freely before starting.
What does a proper lamington taste like?
Light, slightly sweet sponge with a thin, slightly fudgy chocolate exterior and a dry, faintly sweet coconut shell. The overall impression should be light, not heavy or cloying. If yours taste dense, the sponge was overworked. If they taste too sweet, reduce the powdered sugar in the icing by a quarter cup.
