Ingredients

2 cups plain / all purpose flour (cake flour OK too)
2 1/2 teaspoons baking powder
1/4 teaspoon salt
4 large eggs (50 – 55g / 2 oz each), at room temperature
1 1/2 cups caster / superfine sugar (granulated/regular ok too)
115g / 1/2 cup unsalted butter, cut into 1.5cm / 1/2” cubes
1 cup full fat milk
3 teaspoons vanilla extract
3 teaspoons vegetable or canola oil
3 tablespoons lemon zest (from 2 lemons)
1/3 cup lemon juice
1/4 teaspoon natural lemon extract (lemon oil), recommended but not essential
6 1/2 tablespoons plain/all purpose flour (for frosting)
1 1/3 cups full fat milk (for frosting)
1 1/3 cups caster / superfine white sugar (for frosting)
300g / 1 1/3 cups unsalted butter, softened (for frosting)
3 teaspoons lemon zest (for frosting)
4 tablespoons fresh lemon juice (for frosting)

Instructions

Step 1: Preheat your oven to 180°C (350°F) or 160°C fan. Place a shelf in the middle of the oven. Grease three 20cm (8”) cake pans with butter and line with parchment paper.
Step 2: In a large bowl, whisk together the flour, baking powder, and salt. Set aside.
Step 3: Beat the eggs with a stand mixer or hand beater on speed 6 for 30 seconds to aerate. Slowly add sugar over 45 seconds while the mixer runs, then beat on speed 8 for 7 minutes until the mixture triples in volume and turns white.
Step 4: Meanwhile, melt the butter with milk in a heatproof jug in the microwave for 2 minutes or on the stove. Avoid boiling. Keep warm.
Step 5: Gently add the flour to the eggs in three parts: scatter 1/3, beat briefly on low speed, add half of the remaining flour, repeat, and finish with the rest of the flour. Mix just until combined.
Step 6: In the now-empty flour bowl, combine the warm milk and butter, vanilla, lemon juice, lemon zest, oil, and lemon extract. Whisk in about 1 1/2 cups of the beaten egg mixture until smooth and slightly foamy.
Step 7: Pour the milk mixture slowly into the remaining egg batter while mixing on low. Scrape down the sides, then mix briefly just until smooth and pourable.
Step 8: Divide the batter evenly into the prepared pans. Tap each pan on the counter three times to remove large air bubbles.
Step 9: Bake for about 23 minutes or until the cakes are golden and a toothpick inserted in the center comes out clean.
Step 10: Allow cakes to cool in pans for 15 minutes, then turn out onto wire racks to cool completely, flipping upside down if using as layers to achieve flat tops.
Step 11: For the fluffy lemon frosting, place 6 1/2 tablespoons flour and 1 1/3 cups sugar in a saucepan over medium heat. Stir constantly for 30 seconds.
Step 12: Slowly whisk in 1 1/3 cups milk, continuing to stir until the mixture thickens to a custard-like consistency. Remove from heat and transfer to a bowl. Cover with cling wrap pressed to the surface to prevent skin formation. Cool 20 minutes at room temperature, then 30 minutes in the fridge, but do not let it get too cold.
Step 13: Beat 300g softened butter for 3 minutes until pale and smooth using a hand or stand mixer.
Step 14: While mixing on medium speed, add the cooled roux one heaped tablespoon at a time, taking about one minute. Once combined, add 3 teaspoons lemon zest and 4 tablespoons lemon juice, then whip for 2 minutes until stiff peaks form but without overwhipping.
Step 15: Assemble the cake by flipping one layer upside down for a level surface. Spread frosting 3 to 4mm thick, then layer the next cake upside down and repeat. Cover the top and sides with remaining frosting.

Tips & Variations

Use cake flour instead of all purpose for an even lighter crumb.
Granulated sugar works fine if you don’t have caster sugar.
Let eggs come to room temperature for better volume when beating.
If you prefer a tangier frosting, add a little more fresh lemon juice to taste.
Try swapping lemon zest for lime or orange zest for a different citrus twist.
For easier cake layer removal, use cake pans without loose bottoms and line them properly.

Storage

Store the cake covered in the refrigerator for up to 4 days. Bring to room temperature before serving for the best flavor and texture. You can freeze the unfrosted cake layers wrapped tightly for up to 2 months; thaw completely before frosting.

FAQs

Can I make this cake gluten-free?

This recipe relies on regular flour for structure, but you can try substituting a gluten-free flour blend suitable for cakes. Make sure it contains xanthan gum or another binder, and expect slight texture differences.

What can I use if I don’t have natural lemon extract?

Lemon extract adds an extra burst of flavor but is optional. You can omit it or replace with a small amount of lemon zest for natural aroma.
