Light lemon sponge cake
Ingredients
- 100g butter, softened (half fat or light)
- 175g self-raising flour
- 1 teaspoon baking powder
- 175g fine granulated sugar
- 2 whisked eggs
- 6 tablespoons whole milk
- zest of 1 lemon, grated
- 55g butter (half fat or light)
- 1 tablespoon fresh lemon juice
- 2 tablespoons lemon zest, grated
- 250g powdered sugar
- powdered sugar (for dusting)
- fresh raspberries
Instructions
Step 1
Preheat your oven to 160°C (fan). While it heats up, grab your 8x8-inch cake tins and give them a quick rub with butter or a light coat of baking spray—just enough to prevent any sticking. If you're using parchment paper, cut two squares big enough to line the bottom of each tin, then press them smooth so the cake releases perfectly.
Step 2
In a large mixing bowl, crack your eggs into the center. Add the granulated sugar right over the top, then pour in the olive oil in a slow, steady stream while you whisk everything together with a hand mixer or stand mixer. Start on low speed to keep the sugar from flying everywhere, then bump it up to medium-high once the mixture begins to thicken and turn pale yellow—about 2 minutes in. Keep whisking until you’ve got a ribbony batter that leaves a trail when you lift the beaters, about 3–4 minutes total.
Step 3
Here’s your expanded Step 3 with all the details baked in: --- Once your batter turns silky-smooth—light and airy with just a few tiny bubbles dancing on the surface—it’s time to pour it into your prepared cake tin. Gently tap the tin once or twice on the counter to pop any stubborn air pockets and coax the batter into the corners. Give it a quick peek to make sure the parchment paper hasn’t shifted, then smooth the top with a spatula for an even finish. You’ll know it’s ready when the batter looks like a creamy cloud, just begging to be baked into something beautiful.
Step 4
Now slide that golden beauty into your preheated oven at 350°F. Let it bake undisturbed for the first 15 minutes—this gives the edges a chance to set and the top to just begin to color. When the timer rings, pull the tin out and give it a quick turn so the cake browns evenly. Pop it right back in and let it ride for another 18 minutes, until the center springs back when lightly touched and a skewer emerges clean.
Step 5
Here’s your expanded step, written in a warm, conversational style with clear instructions: --- Once the cake has been baking for the full 25–30 minutes, peek through the oven window to check how golden the top has become. You’re looking for a deep amber color—almost like a soft caramel—with slightly crisp edges around the base of the dome. To test for doneness without overopening the oven, quickly insert a toothpick straight into the center of the cake. If it slides out clean, with no wet batter clinging to it, your cake is perfectly baked. Pull it out right away if the pick comes out with just a few moist crumbs—it’ll finish setting as it cools.
Step 6
Let the cake rest right in the pan for about ten minutes—just enough time for the edges to pull away slightly from the sides and the center to firm up a bit. Then, using two thin spatulas or a small offset knife slipped around the edges to help, gently lift the cake onto a clean cooling rack. Leave it there for another 10–15 minutes so the bottom loses its steam and you don’t end up with a soggy bottom. You’ll know it’s ready when the top springs back lightly when pressed with a fingertip.
Step 7
Here’s your expanded Step 7 with all the details you need to bake your second tier with confidence: --- Now it’s time to bake the second layer of your lemon sponge cake. Grab your prepared cake pan—just like you used for the first one—and give it a quick spray with nonstick spray if needed, or line it with a fresh round of parchment paper. This keeps the cakes from sticking and ensures they turn out smooth and easy to remove. Preheat your oven to 350°F (175°C) if it’s not already there—you want it hot and ready before you slide the pan in. Pour your lemon batter into the pan, smoothing the top with a spatula so it’s even. Tap the pan lightly on the counter a couple of times to pop any air bubbles, which helps the cake bake up nice and flat. Slide the pan into the center rack of your oven and bake for 25–30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should just start to pull away from the sides of the pan—that’s your cue it’s done. If the top browns too quickly, tent it loosely with foil for the last 5 minutes. When it’s ready, transfer the pan to a wire rack and let the cake cool for 10 minutes before running a knife around the edges to loosen it. Then flip the cake onto the rack to cool completely. Once it’s at room temperature, you’re ready to stack your tiers or serve it as is.
Step 8
While your cakes cool on their wire rack, set aside a medium bowl and your electric whisk ready to go. In that bowl, beat the softened butter on its own for about 1 minute until it looks pale and fluffy. With the whisk still running, slowly sift in the icing sugar so it doesn’t puff everywhere, then keep whisking until the sugar is fully mixed in. Finally, stop the whisk, add the lemon juice and finely grated rind, and whisk again just until everything is creamy and combined—about 30 seconds should do it.
Step 9
Here’s your expanded Step 9 with a warm, conversational tone and all the details you need to nail it: --- Now that your cakes have cooled completely, grab a small offset spatula or a flat butter knife—whatever feels most comfortable in your hand. You’ll want one that’s long enough to glide smoothly across the surface without tearing the sponge. Place one cake layer on a plate or cake stand, and scoop about half of your buttercream onto the center. Use the back of your knife to gently press it outward, spreading it in even strokes until it just reaches the edges. Don’t worry about perfection here—we’ll clean up the sides later. Take a second to admire your handiwork. That silky layer of buttercream is the first step toward a cake that’s as beautiful as it is delicious.
Step 10
Carefully lift the second cake layer and position it gently over the first, aligning the edges so your sponge sits nice and level. Give the whole thing a little wiggle to help the layers settle, then take a peek at the seams—if you see any buttercream oozing out the sides, just dab it away with a clean finger before it has a chance to make a mess.
Step 11
Now it’s time to finish your lemon sponge with a pretty flourish. Gently spread the remaining buttercream in a smooth layer over the top of the cake, working from the center outward so you don’t disturb the edges. If you like a little sparkle, dust the surface lightly with icing sugar—just a quick sprinkle—so it looks like fresh snow on a lemon grove. Pop a few fresh raspberries on top, wherever they look happiest; they add a burst of color and a little tart bite that balances all that sweet buttercream. Take a step back—you’ve just built something lovely.

My Tip
Gently fold the grated lemon rind into the butter and sugar mixture right after the eggs—this tiny step wakes up the citrus oils so every bite sings with bright, fresh flavour.
Leftovers
Wrap the cooled cake in cling film straight after it’s cooled—this keeps the crumb soft and stops it drying out. It’ll stay fresh in the fridge for up to three days. When you’re ready, warm a slice in the microwave for 10–15 seconds; the gentle heat revives the lemony scent without toughening the sponge.
Make It Your Own
Swap the self-raising flour for **150g plain flour plus 2 tsp baking powder**, then fold in **50g ground almonds** for a tender crumb and a gentle nutty depth.
