This fluffy Australian lamington recipe makes tender vanilla sponge squares dipped in smooth chocolate icing and rolled in desiccated coconut. The cake yields about 16–20 lamingtons, and you can add a traditional layer of raspberry or strawberry jam for a fruity centre.
Each bite has a light, buttery crumb, a soft chocolate coating, and a delicate coconut finish. Chilling the sponge before cutting and dipping makes the squares easier to handle, while the hot-water cocoa icing gives every lamington a glossy, richly chocolatey coating.
Lamingtons are one of Australia’s most recognisable baked treats for good reason. A plain butter sponge becomes something special when it is wrapped in cocoa icing and coconut, creating a contrast of soft cake, creamy chocolate flavour, and lightly chewy texture.
This recipe keeps the sponge simple and dependable. Self-raising flour provides the lift, while creamed butter and sugar give the crumb a delicate richness without making it heavy.
The optional jam filling brings a bright fruit note that cuts through the sweetness. Raspberry jam is the most traditional choice, but strawberry jam also works beautifully and gives the centre a sunny, familiar flavour.

Ingredients You’ll Need
Start with softened unsalted butter, caster sugar, vanilla extract, and three large eggs at room temperature. These ingredients form the buttery base of the sponge, and room-temperature eggs blend more readily into the creamed mixture.
Butter and sugar: Beat 125 g of softened unsalted butter with 150 g of caster sugar for a pale, airy mixture.
Eggs and vanilla: Use 3 large eggs and 1 teaspoon of vanilla extract for structure and gentle flavour.
Dry ingredients: Measure 225 g of self-raising flour for a simple, fluffy sponge.
Milk: Add 125 ml of milk alternately with the flour to create a smooth, spreadable batter.
Fruit filling: Keep 150–200 g of raspberry or strawberry jam ready if you want filled lamingtons.
Chocolate icing: Combine 500 g sifted icing sugar, 40–50 g unsweetened cocoa powder, 125 ml boiling water, and 30 g melted unsalted butter.
Coconut: Prepare 250–300 g of desiccated coconut for rolling.

How to Make It Step-by-Step
Step 1: Heat the oven to 180°C conventional or 160°C fan-forced. Grease and line a 20 cm square cake tin, making sure the paper reaches slightly up the sides so the baked sponge can be lifted out easily.
Step 2: Place the softened butter, caster sugar, and vanilla in a large mixing bowl. Beat until pale and fluffy, scraping the bowl once or twice so the mixture is evenly aerated.
Step 3: Add the eggs one at a time, beating thoroughly after each addition. If the mixture looks curdled, add a spoonful of the measured flour and continue mixing until it comes together.
Step 4: Fold in the self-raising flour alternately with the milk. Use a spatula and stop as soon as no obvious streaks of flour remain, since overmixing can make the sponge less tender.
Step 5: Spread the batter evenly in the prepared tin. Bake for 20–25 minutes, until the top springs back when pressed lightly and a skewer inserted in the centre comes out clean.
Step 6: Leave the cake in the tin for about 10 minutes before turning it onto a wire rack. Allow it to cool completely, since warm sponge is too delicate for clean cutting and dipping.
Step 7: Wrap the cooled cake and refrigerate it for at least 1 hour, preferably overnight. The cold, slightly firm sponge sheds fewer crumbs and stays intact when covered with icing.
Step 8: Cut the chilled cake into 16–20 squares. If you are adding jam, split each square horizontally, spread the cut side with raspberry or strawberry jam, and sandwich the pieces together.
Step 9: Make the coating by whisking the sifted icing sugar and cocoa powder together. Gradually add the boiling water and melted butter, whisking until smooth, glossy, and fairly fluid.
Step 10: Use two forks to lower one cake square into the icing. Turn it gently to coat every side, then lift it above the bowl and let the excess coating drain away.
Step 11: Roll the iced square in desiccated coconut until completely covered. Transfer it to a wire rack, then repeat with the remaining pieces and allow the coating to set.
Pro Tips for Fluffy, Neat Lamingtons
The most important preparation tip is to chill the sponge well. Freshly baked cake is soft and crumbly, while a refrigerated sponge is firm enough to cut into sharp squares and dip without collapsing.
For particularly tidy lamingtons, freeze the uncoated squares for 20–30 minutes before assembly. Do not freeze them after adding jam unless they are wrapped carefully, as the filling can become difficult to spread when very cold.
Keep the chocolate icing warm and fluid, but never hot. If it thickens as you work, whisk in 1–2 teaspoons of hot water at a time until it returns to a dipping consistency.
Use forks rather than your fingers to turn the sponge in the icing. This keeps the coating even and gives excess icing a chance to drip back into the bowl instead of pooling beneath the cakes.
Work with one lamington at a time. Dip, drain, roll in coconut, and move it to the rack before starting the next square so the icing does not dry before the coconut can stick.

Serving Suggestions
Serve lamingtons at room temperature with tea, coffee, or a glass of cold milk. The coconut coating adds enough texture that the cakes need little decoration, making them ideal for afternoon tea, bake sales, school gatherings, and family celebrations.
For a fruit-focused platter, arrange raspberry-filled and unfilled lamingtons together. Add fresh raspberries or sliced strawberries around the serving plate, keeping the fruit separate from the cakes so the coconut stays dry.
You can also cut the sponge into smaller squares for bite-sized treats. Smaller pieces are especially useful when serving several desserts, because guests can enjoy a lamington without taking a large portion.
Storage and Make-Ahead Advice
Store finished lamingtons in an airtight container at room temperature for up to a few days, provided the room is cool. If your kitchen is warm, refrigerate them and let them stand briefly before serving so the sponge softens slightly.
The uncoated sponge can be baked, cooled, wrapped, and chilled overnight before assembly. This make-ahead approach is often easier because the cake is firmer and the decorating work can be completed the next day.
Jam-filled lamingtons should be kept covered so the filling does not dry out. Avoid storing them uncovered in the refrigerator, as the coconut can absorb surrounding aromas and the sponge may lose its pleasant softness.
Fluffy Australian Lamington Recipe
Light vanilla sponge squares are coated in chocolate icing and desiccated coconut, with optional raspberry or strawberry jam between the layers. This classic Australian treat makes approximately 16–20 lamingtons.
Heat the oven to 180°C conventional or 160°C fan-forced. Grease and line a 20 cm square cake tin with baking paper, leaving a little overhang to help lift out the sponge.
Beat the softened butter, caster sugar and vanilla extract until pale and fluffy. Add the eggs one at a time, beating well after each addition; if the mixture begins to curdle, beat in a spoonful of the flour.
Fold in the self-raising flour alternately with the milk, mixing only until the batter is combined. Spread it evenly into the prepared tin so the cake bakes to an even thickness.
Bake for 20–25 minutes, until the top springs back when lightly pressed and a skewer inserted in the centre comes out clean. Cool in the tin for about 10 minutes, then turn the sponge onto a wire rack to cool completely.
Wrap the cooled cake and refrigerate it for at least 1 hour, or preferably overnight. Cut the chilled sponge into 16–20 squares, depending on the size you prefer.
For jam lamingtons, split each square horizontally or split the whole cake before cutting. Spread 150–200 g of raspberry or strawberry jam over the cut surfaces, then sandwich the sponge back together.
Combine the sifted icing sugar and cocoa powder in a bowl. Gradually whisk in the boiling water and melted butter until the icing is smooth and fairly fluid.
Dip each cake square into the chocolate icing, turning it carefully with forks to coat all sides. Let excess icing drain back into the bowl, then roll the square in desiccated coconut.
Place each finished lamington on a wire rack and allow the coating to set. Serve once the chocolate icing is firm, or refrigerate the cakes briefly if you prefer a cooler, denser finish.
Notes
Chill the sponge thoroughly before cutting and dipping. For especially neat squares, freeze the uncoated pieces for 20–30 minutes before dipping. Keep the icing warm and fluid, but not hot; loosen it with 1–2 teaspoons of hot water if it thickens during assembly.
Final Thoughts
This fluffy Australian lamington recipe turns a straightforward vanilla sponge into a memorable chocolate-and-coconut treat. The method is simple, but chilling the cake and keeping the icing at the right consistency will make the finished squares noticeably neater.
Choose raspberry jam for the classic tangy fruit centre or strawberry jam for a softer, sweeter filling. Whether you serve them plain, filled, large, or bite-sized, these lamingtons bring a little Australian bakery charm to any table.
For the best result, allow enough time for the sponge to cool and chill completely. Once the squares are coated and set, all that remains is to brew the tea, arrange the platter, and enjoy their tender crumb with every coconut-covered bite.
