• – 1/2 teaspoon salt
• – 3/4 cup unsalted butter (168 grams) (softened)
• – 1/4 cup vegetable oil (60 ml) (or canola oil)
• – 1 3/4 cup granulated sugar (350 grams)
• – 2 teaspoons vanilla extract
• – 3 large eggs (room temperature)
• – 1 1/2 cups unsalted butter (340 grams) (softened, but still slightly cool to the touch)
• – 2 ounces full-fat cream cheese (56 grams) (brick style, or sub with an additional 1/4 cup butter)
• – 4 1/2- 5 1/2 cups powdered sugar (495-605 grams) (sifted)

Instructions

1. 1
   Lemon Cake Preparation: Bring your oven to a preheated temperature of 350F (180C). Lay rounds of parchment paper along the bottom of your baking pans, then grease and flour the inner walls carefully. Forgoing the protective paper liner and relying strictly on grease and flour is not advised, as the cake layers could easily bind to the pan.
2. 2
   Whisk the whole milk and fresh-squeezed lemon juice together inside a small bowl or measuring vessel, then set aside.
3. 3
   Within a separate medium container, sift the all-purpose flour, baking powder, baking soda, and salt. Whisk the combined dry elements thoroughly and set aside.
4. 4
   In a spacious mixing bowl, cream the softened unsalted butter, vegetable oil, granulated sugar, and fresh lemon zest together until the texture becomes exceptionally light and fluffy, which takes roughly 2-3 minutes.
5. 5
   Blend the vanilla extract directly into the beaten butter mixture. Incorporate the room-temperature eggs into the batter one at a time, making sure to pause your mixer and scrape down the bottom and sides of your container completely after adding each egg.
6. 6
   Gradually integrate the flour mixture and the milk mixture into the creamed butter bowl by alternating between them. To start, mix in a third of the dry ingredients. Then, pour in half of the combined milk and lemon juice. Add the second third of your flour components, follow with the remaining half of the liquid milk base, and finish by adding the final third of your flour elements. Take care to avoid overmixing. It helps to stir the ingredients lightly by hand before starting your mixer at each step. The final batter will display pieces of citrus zest, but it should be completely free of dry flour pockets.
7. 7
   Divide the cake batter uniformly among your prepared cake tins and smooth out the upper surfaces. Place the pans on the middle rack of your preheated oven—ensuring they occupy the same level—and bake for 20-25 minutes. The cakes are fully baked when they begin moving slightly away from the container edges and an inserted wooden toothpick emerges dry or with a couple of moist crumbs attached, but no liquid batter.
8. 8
   Allow the hot cakes to rest inside their tins for a minimum of 20 minutes before carefully flipping them out onto wire racks to finish cooling.
9. 9
   Lemon Frosting Preparation: Inside a large preparation bowl, whip the unsalted butter continuously until it achieves a smooth, creamy texture.
10. 10
    Blend in 3 cups of the sifted powdered sugar along with the fresh-squeezed lemon juice and salt. Initialize your mixer at a low speed settings and beat the elements together until thoroughly integrated.
11. 11
    Pause the mixer to scrape down the inner walls of the bowl. Gradually beat in the rest of your powdered sugar in half-cup portions, alternating with small splashes of heavy whipping cream if the frosting texture feels overly dense, continuing until your preferred level of sweetness is achieved.
12. 12
    Cake Assembly: Verify that your baked cake layers are completely cold to the touch. If the top surfaces have crowned during baking, use a long serrated knife to carefully slice off the rounded tops to make them perfectly flat.
13. 13
    Transfer your first flat cake layer onto the decorative platter or plate you intend to serve the dessert on. Spread roughly 3/4 to 1 cup of the prepared lemon frosting evenly across the top. Position your second cake layer directly on top of the frosted base, coating it with another 3/4 to 1 cup of icing. Place the third cake layer on the very top, then coat the exterior sides and upper surface of the entire cake with decorative swirls of buttercream.
14. 14
    When you are ready to serve dessert, carve individual slices using a thin, sharp knife. Utilizing a standard dull table knife for cutting is not recommended.

Frequently Asked Questions

Why do I need to mix the milk and lemon juice together first? Combining the whole milk and fresh lemon juice effectively creates a homemade buttermilk alternative. The acid slightly curdles the milk, which breaks down tight gluten strands in the flour mixture to yield an incredibly soft, moist, and tender cake structure.

Can I substitute bottled lemon juice for fresh juice in this cake? It is highly recommended to use real, freshly squeezed lemon juice rather than bottled concentrates. Bottled juice contains preservative elements that create a harsh, synthetic aftertaste, whereas real lemons provide that bright, signature flavor profile.

How do I prevent my lemon layer cake from turning out dense or heavy? The main culprit behind heavy cakes is overmixing. When alternating between adding your flour elements and milk mixture, combine them using very low mixer speeds or a rubber spatula until just incorporated. This stops excess gluten from forming.

What is the secret to getting smooth, stable lemon buttercream frosting? The secret lies in the temperature of your butter and adding a touch of brick-style cream cheese. Ensure your butter is softened but still slightly cool to the touch. If the frosting gets too stiff, slowly beat in 1-2 tablespoons of heavy whipping cream until silky.
