This layered lemon cake is so incredibly soft. It is full of a fresh lemon flavor thanks to the Vinci Hands Free Juicer. Their juicer is very easy to use and let’s you get lemon juice super fast!
The best part about the cake is the white chocolate frosting. The frosting tastes like a white chocolate truffle! It is a very sweet frosting which is why it is goes perfect with this lemon cake. It is the star of the show at special occasions.

Why This Lemon White Chocolate Cake Recipe Works
- Lemon cake- This cake recipe makes three 8-inch cake layers that are full of fresh lemon flavor.
- White chocolate frosting- The frosting is a very rich and creamy buttercream. It has 8oz of white chocolate in this frosting!
- Layered cake- This cake is layered, but it can easily be made with other cake pans. See the FAQ for the cake pans.
The Best Hands Free Juicer
Vinci Housewares has the BEST hands free juicer. It has smart auto juicing technology that will raise up the half of the lemon (or any other type of citrus fruits) and will automatically squeeze all of the juice out!
What I loved about using the Vinci Hands Free Juicer is that it saved my hands from juicing the lemon myself. All I had to do was push half the lemon in, press a button, and it took seconds!
It also has a spout for you to pour the lemon juice right into the cup. Also, it didn’t break the rind, so I was able to zest the rest of the lemon for this recipe.
All of the juicer parts are easy to dissemble ( and reassemble!) for easy clean up.
Ingredient Notes for White Chocolate Cake
Here are some notes on the ingredients. For a full list of ingredients, check out the recipe card below.
- Unsalted butter- Pull the butter out for the cake batter 2 hours before baking. For the frosting, it needs to be slightly cold to get the best texture. Let it sit on the counter for 30 minutes before using.
- Oil- Use canola oil or vegetable oil.
- Lemons- Use a zester to zest the lemons and Vinci Hands Free Juicer to get the lemon juice.
- Sour cream- Use full fat sour cream. Pull this out 2 hours before baking.
- Eggs- Pull the large eggs out 2 hours before baking so they are room temperature.
- Buttermilk- You can use full fat or reduced fat buttermilk. Pull this out 2 hours before baking.
- Powdered sugar- Make sure this is sifted to avoid a gritty frosting.
- White chocolate- Use two bars of white chocolate. Use a high quality white chocolate bar.
Substitutions
Sour cream- You can use plain greek yogurt instead.
Buttermilk- Actual buttermilk is best, however you can use 1 cup whole milk with 1 Tablespoon of lemon juice. Let it sit for 10 minutes before using.
I don’t recommend using white chocolate chips for this recipe. It needs to be the white chocolate bars for the melted chocolate. White chocolate truffles may have the same issues as the chips.
Step By Step Instructions- Cake Layers
Here is how to make and bake the lemon cake layers. This recipe use a stand mixer with a paddle attachment, or a hand mixer (electric mixer). Heat oven to 350°F.
STEP 1: Mix the dry ingredients. First, sift the all-purpose flour in a medium bowl. Then, add the baking powder, baking soda, and salt. Before you start on the batter, prep the lemon zest and lemon juice.
STEP 2: Beat butter, oil, and sugar. Using a mixer, beat the butter, oil, and white sugar on high speed for 3 minutes in a large mixing bowl. Then, add in sour cream, lemon zest, and lemon juice. Mix on medium speed until just combined.
STEP 3: Add in eggs. Next, add in the eggs one a time. Mix these in for 1 minutes on high speed.
STEP 4: Alternate between flour mixture and buttermilk. Alternate between these two and mix on low speed. Make sure the batter is not over mixed.
Scrape the sides of the bowl with a rubber spatula.

STEP 5: Pour batter. Divide batter evenly into three 8-inch cake pans. The pans needs to be sprayed with baking spray. Use a baking spray with flour, not a cooking spray for best results.
STEP 6: Bake the cake. Bake the cake for 22-24 minutes until a toothpick inserted comes out clean.
STEP 7: Cool the cake. The cake layers need to be cool on a cooling rack completely before decorating.
Step By Step Instructions- White Chocolate Frosting
STEP 1: Prepare the ingredients. First, pull the butter out for 30 minutes to get slightly cold. Before making the frosting, make sure to sift the powdered sugar and melt the white chocolate in a separate bowl.
The white chocolate needs to cool before using.
STEP 2: Beat the butter. Using a mixer, beat the butter on high speed for 3 minutes in a large bowl.
STEP 3: Add the powdered sugar. The powdered sugar needs to be added on low speed. It will be very thick!
STEP 4: Add the wet ingredients. Next, pour in the melted white chocolate, vanilla extract, heavy cream, and salt. The frosting needs to be beaten on high for 2-3 minutes so it is extra creamy.
Assembling The Cake Tips
- Pipe a small amount of frosting on the board you are decorating on. This will keep the cake locked in place as a kind of glue in the center of the cake.
- Place the first cake layer down and spread 1 1/2 cups of frosting on the cake by using an offset icing spatula. Repeat with the second cake layer.
- Place the last cake layer with the bottom of the cake facing up. This gives the cake the flattest edge possible.
- Frost the cake in a thin layer of frosting the first time. Then, freeze for 15 minutes. This crumb coat will lock the cake crumbs in place.
- Frost the rest of the cake by. I used a metal cake scraper to get a semi naked look on the sides of the cake.
Decorating The Cake
I used a Wilton 1M tip and a piping bag to pipe the border on the top of the cake. Then, place lemon triangles and white chocolate chips on top of cake to finish.

Do you think a raspberry filling would work in this cake recipe?
Thank you!
Yes it would!
You specify in the recipe that the cake batter is for three 8″ pans, yet, when I read your notes you refer to three 6″ pans or two 9″ pans. Which is it?
So the cake batter can fit in all three options. I used three 8-inch cake layers. If you want a taller and thicker cake use the three 6-inch cake pans. For a shorter and wider cake, use two 9-inch cake pans.
