Simple Raspberry Lamington Sheet Cake It is a quiet Sunday afternoon, the sun is pouring through the kitchen window, and the fragrant aroma of vanilla and raspberries is in the air. I am at the counter, lightly dusted with powdered sugar, holding a tray of fluffy, sticky, mouth-watering Raspberry Lamington Sheet Cake you’ve ever seen. This is not just an ordinary cake. This is simplicity and indulgence at its best.
If you have never heard of a Lamington, let me introduce you to the very best of Australian things! Traditionally a Lamington is sponge cake that is dipped in chocolate and rolled in coconut. In this case, I have taken that traditional style and added a fun and fruity twist. Instead of dark chocolate icing, this will be topped with bright raspberry glaze. Also, this will be a sheet cake, instead of individual squares. Why? Because life is too short to limit delicious cake to small portions.
This Raspberry Lamington Sheet Cake is a true find. It’s so moist, fluffy, and full of the delightful tangy sweetness of raspberries. With the coconut’s crunchy goodness and glaze lending it that glossy, insta-perfect finish – what’s not to like? And of course, a dessert that’s impressive but doesn’t take a lot of time or effort is always a winner. This cake is so easy to make, you’ll be feeling like a pastry chef even if you aren’t much of a baker.
What I love most about this recipe is its versatility. It’s perfect for family gatherings, potlucks, or just any cozy night-in curled up with your favorite cup of tea. And I mean, who’s not a sucker for elaborate-looking desserts that are incredibly simple? It’s a ton of fun too, to introduce your family and friends to Lamingtons!
So whether you are an expert baker or someone who is new to baking, this Raspberry Lamington Sheet Cake will make your life sweeter! And trust me, once you’ve made this cake, you’ll be wishing you made another one!

Here’s a little story about how this recipe became a regular in my house. It all started one day when my husband, a chocolate purist, agreed to try a slice.

Ingredients
Instructions
-
Start by preheating your oven to 350°F (175°C) and greasing a 9x13 inch baking pan.
-
In a large bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
-
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the butter mixture, alternating with the milk, and mix until just combined.
-
Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
-
While the cake is cooling, make the raspberry glaze. Blend the raspberries until smooth, then strain to remove the seeds. Mix the raspberry puree with powdered sugar until you achieve a thick, glossy glaze.
-
Once the cake has cooled, spread the glaze evenly over the top and sprinkle with shredded coconut. Slice and serve!
