From the perfect balance of butter and milk to the fresh lemon zest that wakes up your palate, you’ll find these essentials are everything you need to bake up something magical.
- 2 cups plain / all purpose flour: The base of your cake, providing structure that’s tender and light.

- 3 tsp vanilla extract: Deepens flavor for a subtle warmth under the lemon notes.

How to Make Lemon Cake with Secret Fluffy Lemon Frosting Recipe
Step 1: Preheat and Prepare Your Pans
Start by preheating your oven to 180°C (350°F) to create the perfect environment for even baking. Grease and line three 8-inch cake pans with parchment paper to ensure your layers come out cleanly and maintain their soft shape—a crucial foundation for your Lemon Cake with Secret Fluffy Lemon Frosting Recipe’s beautiful presentation.
Step 2: Combine Dry Ingredients
In a large bowl, whisk together the flour, baking powder, and salt. This simple blend ensures every bite has the right lift and balance without any unpleasant pockets of rising agent or salt, setting up the perfect base for mixing in your wet ingredients later.
Step 3: Beat Eggs and Sugar to Airy Perfection
Using a stand mixer or hand whisk, beat the eggs for about 30 seconds to aerate, then gradually add sugar over 45 seconds while continuing to beat. Push your mixer to high and whip for 7 minutes or until the mixture triples in volume and turns pale white. This step is where your cake gains its remarkable lightness — the secret to a crumb that practically melts in your mouth.
Step 4: Melt Butter and Warm Milk
While beating eggs, gently melt butter in full-fat milk until combined and warm but not boiling. This liquid will be added carefully to the batter later, bringing moisture and richness that keeps your layers tender and flavorful.
Step 5: Gradually Incorporate Flour and Milk Mixture
With the eggs whipped, fold one-third of the flour mixture into the batter gently on low speed for just a few seconds. Repeat this action adding half of the remaining flour, then fold in the rest, taking care not to overmix, which can toughen your cake. Next, whisk lemon juice, zest, vanilla, and oil into the milk-butter warm mixture, then slowly combine this liquid into your batter, creating a smooth, pourable cake batter bursting with citrus essence.
Step 6: Bake Your Layers
Divide the batter evenly into the prepared pans. Tap each pan on the countertop a few times to release large bubbles that could cause holes or uneven texture, then bake for about 23 minutes or until a toothpick inserted into the center comes out clean. Your kitchen will soon fill with an irresistible lemon aroma that will get you excited for the next step.
Step 7: Cool and Prepare for Frosting
Once baked, cool the cakes in their pans for 15 minutes before transferring to wire racks to cool completely. For the neatest layers, flip the cakes upside down as they cool to flatten any domed tops. Now it’s time to bring the magic frosting into play to finish your Lemon Cake with Secret Fluffy Lemon Frosting Recipe!
Step 8: Make the Secret Less-Sweet Fluffy Lemon Frosting
Start by cooking flour and sugar over medium heat for about 30 seconds to create a roux. Slowly whisk in milk to avoid lumps, stirring constantly until thickened into a custard-like paste. After removing from heat, cover with cling wrap pressed onto the surface and cool until thick but not cold. Beat softened butter until pale and fluffy, then add the cooled custard one tablespoon at a time while whipping continuously. Finish by folding in fresh lemon zest and juice, whipping just enough to hold peaks without becoming sticky. This frosting is the heart of this recipe’s charm – fluffy, tangy, and less sweet than typical frostings.
Step 9: Assemble Your Cake
Spread the luscious frosting evenly between each cake layer and over the top and sides. The light lemon flavor combined with the tender crumb feels like a luxurious treat that’s both refreshing and decadently comforting, making it a perfect centerpiece for any celebration or just a joyful indulgence.
How to Serve Lemon Cake with Secret Fluffy Lemon Frosting Recipe

Garnishes
To enhance the bright citrus notes visually and flavor-wise, garnish your cake with thinly sliced lemon wheels, a sprinkle of additional fresh lemon zest, or a few edible flowers. These finishing touches not only add elegance but also give your guests a hint of the refreshing taste baked inside.
Side Dishes
If you want to complement your cake, consider serving alongside a scoop of vanilla bean ice cream or a dollop of whipped cream. Fresh berries, such as raspberries or blueberries, also pair wonderfully with the tart lemon flavors, creating a refreshing balance that’s simply irresistible.
Creative Ways to Present
For a stunning presentation, try serving individual slices with a drizzle of homemade lemon glaze or a sprinkle of crushed pistachios for a bit of color and crunch. Another fun idea is to cut the cake into petite squares or cupcakes and pipe the secret fluffy lemon frosting on top, making it perfect for parties and easier to share.
Make Ahead and Storage
Storing Leftovers
Your Lemon Cake with Secret Fluffy Lemon Frosting Recipe keeps wonderfully in an airtight container in the refrigerator for up to four days. Keeping it chilled helps maintain the frosting’s fluffy texture and the cake’s moist crumb, ensuring every slice tastes as fresh as the first.
Freezing
You can freeze unfrosted cake layers individually wrapped in plastic and aluminum foil for up to two months. To freeze the assembled and frosted cake, flash freeze uncovered until firm, then wrap tightly and freeze. Thaw overnight in the refrigerator for the best texture and flavor retention before serving.
Reheating
This cake is best served chilled or at room temperature; avoid reheating as the frosting will soften too much. If you’d like your cake slightly warmer, let it sit at room temperature for 20-30 minutes before slicing, allowing the flavors to shine without compromising the frosting’s fluffiness.
FAQs
Can I use cake flour instead of all-purpose flour?
Yes, cake flour works beautifully here and can make the cake even more tender. If substituting, keep the quantity the same, but expect a slightly more delicate crumb.
Is the secret fluffy lemon frosting very sweet?
Not at all! This frosting is designed to be less sweet than traditional buttercreams, highlighting the fresh lemon flavor in a light, airy texture that balances the cake perfectly.
Can I make this recipe dairy-free?
With some ingredient swaps like plant-based milk and butter alternatives, you can adapt the cake and frosting. However, the texture may vary since dairy plays an important role in moisture and creaminess here.
How important is it to use fresh lemon zest and juice?
Fresh lemon components are key to vibrant flavor and aroma. Bottled lemon juice won’t provide the same brightness or depth, so fresh is always best for this recipe.
Why do I need to beat the eggs and sugar until tripled in volume?
This step introduces air into the batter, making the cake layers incredibly light and fluffy. Skipping it can result in a denser cake, so give it the time it deserves!

Secret Less-Sweet Lemon Frosting
- 6 1/2 tbsp plain/all purpose flour
- 1 1/3 cups milk (full fat preferred, low fat OK)
- 1 1/3 cups caster / superfine white sugar (or granulated)
- 300g / 1 1/3 cups unsalted butter, softened
- 3 tsp lemon zest (from 1 lemon)
- 4 tbsp fresh lemon juice
Instructions
- Preparation: Preheat the oven to 180°C/350°F (160°C fan) for 20 minutes before starting the batter. Grease three 20cm/8” cake pans with butter and line with parchment paper. Place the oven shelf in the middle position.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt. Set aside.
- Beat Eggs Until Aerated: Using a stand mixer with a whisk attachment or hand beater, beat eggs on speed 6 for 30 seconds. Pour in sugar slowly over 45 seconds while beating continues. Then beat on speed 8 for 7 minutes until the mixture triples in volume and turns white and thick.
- Heat Milk and Butter: While beating the eggs, melt butter in milk by microwaving on high for 2 minutes or gently warming on the stove. Do not let it boil; foam is acceptable. Keep warm if preparing early.
- Gently Add Flour to Egg Mixture: Sprinkle one-third of the flour mixture over the beaten eggs and beat on low speed for 5 seconds. Add half the remaining flour and mix again at low speed for 5 seconds, then add the rest and mix until just combined. Avoid overmixing.
- Mix Milk with Egg Batter: In the empty flour bowl, combine warm milk-butter mixture with vanilla extract, lemon juice, lemon zest, and oil. Add about 1 1/2 cups (2 ladles) of egg batter and whisk vigorously until smooth and slightly foamy.
- Combine Milk Mixture with Egg Batter: On low speed, pour the milk mixture slowly into the remaining egg batter over 15 seconds. Stop mixing and scrape the bowl’s sides and base. Beat again briefly on low speed until batter is smooth and pourable.
- Bake the Cake: Divide batter evenly among the prepared pans. Tap each pan on the counter three times to release air bubbles. Bake for 23 minutes or until golden and a toothpick inserted in the center comes out clean.
- Cool Cakes: Remove cakes from oven and let cool in pans for 15 minutes. Turn cakes out onto racks to cool completely, cooling upside down if layering to flatten slight domes. Level cakes as needed.
- Prepare the Lemon Frosting Thickening Roux: In a large saucepan over medium heat, cook flour and sugar together, stirring constantly for 30 seconds. Gradually whisk in milk, continuously stirring to avoid lumps, and cook until mixture thickens to a thick, dolloping custard consistency. Remove from heat.
- Cool the Roux: Transfer the thickened custard into a bowl, cover tightly with cling wrap pressed directly onto the surface to prevent skin formation. Let cool for 20 minutes at room temperature, then refrigerate for 30 minutes until thick but not chilled through.
- Cream Butter for Frosting: Using a handheld or stand mixer with a whisk attachment, beat softened butter on medium speed for 3 minutes until pale and creamy.
- Combine Roux with Butter and Flavor: Gradually add the cooled roux one heaped tablespoon at a time while beating on medium speed (speed 5 if using stand mixer). Once fully combined, add lemon zest and fresh lemon juice, then whip for 2 minutes until frosting holds stiff peaks like whipped cream. Avoid whipping beyond 4-5 minutes to prevent stickiness.
- Frost the Cake: Spread the lemon frosting evenly over the cooled cake layers to assemble and decorate your lemon cake.
Notes
- Note 1: Cake flour can be used instead of all-purpose flour for a lighter crumb.
- Note 2: Ensure baking powder is fresh to allow proper rising. Regular granulated sugar works although superfine dissolves faster.
- Note 3: Eggs should be at room temperature to maximize volume when beating.
- Note 5: Full-fat milk is recommended for richness; low-fat milk is acceptable, but avoid skim milk.
- Note 6: Use a high-quality vanilla extract for the best flavor impact.
- Note 7: Vegetable or canola oil adds moisture without altering flavor.
- Note 8: Lemon oil or natural lemon extract enhances citrus flavor but is optional.
- Note 9: Preheating the oven fully ensures even baking.
- Note 10: Use cake pans without loose bottoms if possible; knocking pans helps eliminate large air bubbles for even texture.
- Note 13: Stir constantly during roux cooking to avoid lumps and burning; custard should be thick enough to hold shape.
- Note 14: Cooling the roux properly without chilling ensures smooth frosting consistency.
