And it’s good. The lemon curd is the best part, so sweet and perfectly tangy. Mmmm. I could bathe in it. And the buttercream is so light and sweet, yet still with just enough tang. The cake is nicely dense and delicious. It’s all a perfect combo.
I made it the first time for my mom’s birthday in July and I was surprised how much of a hit it was.
My family has never really been big on lemon. My grandmother loves lemon and we’ve had lemon cakes for her birthday before. But I can’t say anyone else was ever really into it.
So imagine my surprise when my mom requested it for her birthday. Her cake was two-tiered, so I made the smaller tier the lemon cake because I thought for sure it would be less popular than a chocolate cake.
I was wrong.
Ingredients
Cake
2 cups all purpose flour
1 1/2 cups sugar
3/4 tsp baking powder
1 tsp baking soda
1/2 tsp salt
3 eggs
2/3 cup oil
2/3 cup fresh lemon juice
3/4 cup sour cream
Lemon Curd
1/4 cup fresh lemon juice (about 1-2 lemons)
2 tsp finely grated lemon zest
1/3 cup sugar
4 egg yolks
3 tbsp butter (I used unsalted)
Lemon Buttercream
1 1/2 cups butter
1 1/2 cups shortening
12 cups (3 lbs) powdered sugar
3 tsp finely grated lemon zest
6 tbsp fresh lemon juice
3/4 tsp vanilla
1-2 tsp water - plus more to the consistency you want
Instructions
Cake
1. Combine flour, sugar, baking powder, baking soda and salt in a large bowl and whisk together.
2.Add eggs, oil and lemon juice. Beat until smooth.
3. Add sour cream and beat until smooth.
4. Bake at 350 degrees in two 8-inch pans for about 25 minutes or until done.
Lemon Curd
1. Combine all ingredients in a double boiler (or in a metal bowl over a pot of simmering water, like I did).
2. Heat while stirring constantly with a whisk.
3. It is done when it's thick enough to coat the back of a spoon. You will be able to tell it has thickened, but I wouldn't say that it's "thick."
4. Refrigerate until cool and thick.
Lemon Buttercream
1. Beat butter and shortening together until smooth.
2. Add 6 cups of powdered sugar, one at a time, beating to combine.
3. Add lemon juice, lemon zest and vanilla and combine.
4. Add the remaining powdered sugar and beat to combine.
5. Add water to get the consistency you want, starting with 1/2 tsp, beat to combine.
To assemble the cake:
1. Divide the cake into four layers by slicing each cake in half.
2. Fill two layers with lemon buttercream and the other two with lemon curd.
3. Frost the outside of the cake.
Enjoy!
