How to Make Lemon Layer Cake with Lemon Curd and Buttercream Frosting Recipe

Step 1: Prepare Your Pans and Dry Ingredients

Start by preheating your oven to 180°C (350°F) and line two 7-inch cake tins with parchment paper, greasing them lightly to ensure easy cake removal. In a bowl, whisk together your sifted all-purpose flour, baking powder, baking soda, and salt, ensuring they are evenly combined. This sets the foundation for your cake’s rise and tenderness.

Step 2: Combine Sugar and Lemon Zest

In a separate large bowl, rub the granulated sugar and lemon zest together for a few minutes until the sugar is fragrant and slightly moist. This step is the secret to infusing the cake with a wonderfully fresh lemon aroma that will carry through to every bite.

Step 3: Cream Butter, Oil, and Sugar Mixture

Add the unsalted butter to the lemon-infused sugar and whisk for about 2-3 minutes until the mixture is light and fluffy. Then stir in the oil, continuing to whisk until everything is fully incorporated and silky smooth. This combination ensures your cake stays moist, tender, and richly flavored.

Step 4: Add Eggs One at a Time

Incorporate the eggs one by one, whisking each separately into the batter on medium speed for about 2 minutes. This careful incorporating creates a smooth batter with good volume. Don’t forget to add lemon extract now for that extra lemony kick!

Step 5: Mix in Liquid Ingredients

Pour in the buttermilk, milk, and lemon juice, whisking together for 2-3 minutes to combine. These ingredients add moisture and that signature tangy layer of flavor that makes each forkful so special.

Step 6: Combine Dry and Wet Ingredients

Add about a third of the dry ingredients to the wet ingredients and whisk just until combined, then repeat until all dry ingredients are incorporated. Be careful not to overmix to maintain the cake’s tender crumb — a few lumps are okay!

Step 7: Bake the Cake Layers

Distribute the batter evenly into your prepared cake tins and bake for 30 to 45 minutes. Check doneness by gently inserting a wooden skewer in the center of each cake; if it comes out clean, your cake layers are beautifully baked and ready to cool.

Step 8: Cool the Cakes

Once out of the oven, invert the cakes onto cooling racks so they can cool completely. Proper cooling is essential before frosting to avoid melting or sliding layers.

Step 9: Prepare the Lemon Buttercream Frosting

While the cakes cool, make the frosting by stirring unsalted butter and icing sugar in a bowl for a minute, then whisking for another 2-3 minutes until fluffy. Add lemon zest, lemon juice, double cream, and yellow food coloring, whisking for 3-5 more minutes until the frosting is light, airy, and sunglow yellow.

Step 10: Warm the Lemon Curd

Gently heat the lemon curd in a saucepan over low heat just until it loosens slightly, making it easier to spread between cake layers without running off.

Step 11: Assemble Your Lemon Layer Cake with Lemon Curd and Buttercream Frosting Recipe

Place one cake layer on your cake board or serving plate, spread a generous layer of lemon buttercream evenly across the top, smooth it out, then spoon on the warmed lemon curd. Add the second cake layer and frost the entire cake evenly with the remaining lemon buttercream. Smooth down the sides for a clean, elegant finish.

Step 12: Decorate and Enjoy

Finish by piping extra buttercream swirls on top if you like, then garnish with fresh lemon slices and delicate baby’s breath flowers for a charming look that’s truly show-stopping. Now your Lemon Layer Cake with Lemon Curd and Buttercream Frosting Recipe is ready to be devoured and admired!

Make Ahead and Storage

Storing Leftovers

Leftover cake can be stored in an airtight container in the refrigerator for up to 3 days. Make sure it’s well covered to keep the frosting from drying out or absorbing fridge odors. Before serving, let it come to room temperature to regain that melt-in-your-mouth softness.

Freezing

You can freeze this Lemon Layer Cake with Lemon Curd and Buttercream Frosting Recipe by wrapping it tightly in plastic wrap and then in foil to prevent freezer burn. Freeze for up to 2 months. To thaw, place in the fridge overnight, then bring to room temperature before serving to preserve the perfect texture.

Reheating

This cake is best enjoyed cool or at room temperature rather than reheated. If you want a slightly softer texture, allow it to sit out for an hour, or give chilled slices a few seconds in the microwave on low power, just enough to take the chill off without melting the frosting.

FAQs

Can I use regular milk instead of buttermilk in this Lemon Layer Cake with Lemon Curd and Buttercream Frosting Recipe?

Yes, you can substitute regular milk mixed with a tablespoon of lemon juice or white vinegar to mimic buttermilk’s acidity. Let it sit for 5-10 minutes before using to ensure the right texture and tang.

How do I prevent the lemon frosting from being too runny?

If your frosting is too loose, add more icing sugar a tablespoon at a time while whipping. Also, ensure your butter is not too warm. Adding a bit more double cream can help adjust the consistency but be cautious not to add too much at once.

Can I make this cake gluten-free?

Absolutely! Use a high-quality gluten-free flour blend that includes xanthan gum to replace the all-purpose flour. Keep in mind texture may vary slightly, but the overall flavor will remain stunning.

Is it possible to make this cake vegan?

With some substitutions like using vegan butter, flax eggs instead of eggs, and plant-based milk, you can create a vegan version. Just remember lemon curd and buttercream frosting will also need to be adapted, but vegan lemon curd recipes are available online.

How do I keep the cake layers moist?

Using room temperature ingredients and not overmixing the batter helps keep the layers tender. The oil and buttermilk also play essential roles in locking in moisture. Avoid overbaking by checking with a skewer to ensure the cake stays soft.
