Description
Simple, easy and delicious lemon cake with lemon frosting and chocolate ganache!
Ingredients
Cake Ingredients:
3 cups all-purpose flour
1 tablespoon baking powder
1 teaspoon baking soda
1 teaspoon salt
1 cup butter (2 sticks), softened
2 cups granulated sugar
4 eggs
4 teaspoons vanilla extract
1 cup sour cream
Juice and zest of 3 lemons (approximately 9 tablespoons)
Lemon Curd Ingredients:
1/2 cup sugar
Juice and zest of 3 lemons (approximately 9 tablespoons)
4 egg yolks
6 tablespoons butter
Lemon Buttercream Ingredients:
2 cups butter, softened
5-6 cups powdered sugar
Zest of two lemons
Juice of one lemon (approximately 3 tablespoons)
1 teaspoon vanilla extract
1 teaspoon lemon extract
Chocolate Ganache Ingredients:
1 cup semi-sweet chocolate chips (I always use Ghiradelli)
1/3 cup heavy cream
Instructions
Cake Directions:
Preheat the oven to 350 degrees F. Grease and line the bottoms of three 6″ cake pans with parchment paper. Set aside. In a medium bowl, whisk together the dry ingredients, flour through salt.
In your stand mixer fitted with the paddle attachment, beat together the butter and sugar until light and fluffy. Add the eggs one at a time, beating until incorporated, and scraping down the sides of the mixing bowl as needed. Add the vanilla extract. Add the dry ingredients and mix on low until just incorporated, being careful not to overmix. Add the sour cream, lemon juice and zest, mixing until all ingredients come together.
Pour batter into the three prepared cake pans, and bake in the preheated oven for 22-30 minutes, or until a toothpick comes out with moist crumbs.
Allow the cakes to cool in their pans for about 5-10 minutes, and then turn them out on a wire cooling rack to cool the rest of the way. I like to turn my cakes upside down to help them flattten. When the cakes are room temp, I freeze them for 30 minutes to make frosting them easier.
Lemon Curd Directions: Combine all ingredients in a medium saucepan over medium-low heat. Be sure to whisk constantly so the mixture doesn’t burn. Cook about 10 minutes, or until the mixture is thick enough to coat the back of a wooden spoon. Remember that the curd will continue to thicken as it cools! Remove the curd from the heat, and melt in the butter. Store in the fridge for up to 5 days.
Lemon Buttercream Directions: In the bowl of your stand mixer fitted with the paddle attachment, beat the butter on high speed until light and fluffy. Add 5 cups powdered sugar one cup at a time, starting your mixer on low and increasing to high with each addition. Add the lemon zest, juice and extracts, mixing on high speed for about 3-4 minutes. Add the additional cup of powdered sugar if necessary. Taste! If you’d like the frosting to taste even more like lemon, add additional zest!
Chocolate Ganache Directions: Combine the chocolate chips and heavy cream in a small mixing bowl. Heat in the microwave for about 30 seconds, and stir well. Add a few more seconds if the chocolate chips aren’t fully melted. Drizzle the chocolate ganache over the sides of the cake with a spoon, or using a squeeze bottle. Then drizzle the chocolate over the rest of the top of the cake and smooth. For this cake I did an inverted drip, which just means that I frosted the cake, did the drizzle, and flipped it over!
Notes
If necessary, cut the top of each cake so that they’re flat. This will make frosting easier! I like to do this with cold (refrigerated) cakes and a sharp bread knife.
Cover the top of the first layer of cake with the lemon buttercream. Pipe a border of frosting around the circumference of the cake. Spoon lemon curd into the well you’ve created. Top with the second layer of cake, and repeat steps. Then top with the third layer of cake, and frost the cake lightly for a semi-naked cake like mine, or completely for a fully frosted cake.
If you want to decorate with lemon slices, this is my trick – toothpicks! I push toothpicks through the lemon rind, far enough in that you can’t see them. Voila! Obviously remove all the picks before serving.

Lemons come in all shapes and sizes. How many tablespoons of lemon juice in the recipe for the cake and how many tablespoons of lemon juice in the recipe for the lemon curd? Must be more specific. Going to make your cake real soon but I need the answer ASAP thank you

Hi Katie, thanks for your comment. A good rule of thumb is to assume that each lemon will give about 3 tablespoons lemon juice! I’ll update the recipe too – happy baking!

Thank you for the 2x and 3x scale. Question though: What size baking pans equate to the 2x and 3x scaled up? This cake sounds delectable and it’s very prettily decorated. I plan to bake this for a friend’s birthday. She loves both lemon and chocolate.

I’ve made this recipe once and it was great but had some issues with the curd and I think it’s because the directions are a bit unclear. It says to add all ingredients in the sauce pan but then at the very end of the directions it says to melt in the butter. Do you add the butter with everything else or cook everything AND THEN add the butter? Could you clarify please?
