Equipment

Ingredients

Lemon Cake Layers

  • 3 ¼ cups all-purpose flour
  • 3 cups granulated sugar
  • 2 ½ teaspoons baking powder
  • 1 teaspoon salt
  • 1 cup unsalted butter or 2 sticks, room temperature
  • 5 eggs
  • 1 ½ cups buttermilk room temperature - or milk + juice of 2 lemons
  • 1 teaspoon clear vanilla extract
  • 2 Tablespoons lemon extract
  • 2 Tablespoons lemon zest I recommend fresh, but dried lemon zest is another option
  • 3-4 drops yellow food coloring (optional)

Frosting / Filling

  • 8 ounces cream cheese one package, softened
  • 1 cup butter 16 Tablespoons or two sticks, softened
  • 5-6 cups powdered sugar
  • 2 Tablespoons lemon extract
  • 1/4 teaspoon salt if using unsalted butter
  • Lemon pudding / Lemon curd (either or both - both optional)
  • 5 Lemon Oreos (chopped)

Drip (optional) & Decorations

  • 4 ounces white candy melts (or ½ cup; for cake drip)
  • 2 - 2 ½ Tablespoons heavy whipping cream (for cake drip; start with 2 Tbsp and add more if needed)
  • 5-6 Lemon Oreos

Instructions

Lemon Cake layers

  • Preheat oven to 350°F. Prepare 3 8-inch cake pans with non-stick or baker’s floured cooking spray (or line with parchment rounds).
  • Mix together all dry ingredients (flour, sugar, baking powder, and salt) in a stand mixer with a paddle until fully combined. (A hand mixer will work as well)
  • Mix bits of room-temperature butter slowly into the dry mix, on a low speed. Continue to mix until no large chunks of butter remain, and the mixture becomes crumbly.
  • Pour in eggs and mix on low until just incorporated. Add in the buttermilk, vanilla, lemon extract, lemon zest, and food coloring if desired, and mix at a low speed until combined. Scrape down the sides of the bowl with a spatula, then beat on medium speed for about 30 seconds.
  • Divide batter evenly between the prepared cake pans (I find a kitchen scale helpful for this part). This guarantees your layers will bake to be the same height.
  • Bake for 35-37 minutes (or until a toothpick comes out clean). Allow cake layers to cool for 10-15 minutes on a wire cooling rack before removing from pans – it helps to run an offset spatula or knife around the perimeter of the pan first. Cool completely. (Set in the fridge or freezer to accelerate the cooling process if desired.)
  • Once the layers have fully cooled, use a serrated knife or cake leveler to cut each horizontally into 2 layers. Be sure the layers are completely cooled or chilled first; if cut while still warm, they'll tend to crumble and break.
  • In the meantime - start your frosting!

Frosting

  • Beat together softened cream cheese and butter; slowly add in powdered sugar alternating with lemon extract until frosting reaches an easily spreadable consistency. Add salt if needed and beat until well combined.
  • (Filling (optional) – I used Preppy Kitchen’s Lemon Curd recipe + Lemon pudding mix combined with 1 ½ cups of milk to fill the cake in the photos / video. Optional - and more work - but definitely delicious! If you’d like to skip the extra steps, you can purchase pre-made lemon curd or just fill the cake with frosting.)

Assembly

  • Place a smear of frosting on your cake circle (to keep the cake from sliding while you decorate it) and center your first cake layer in the center of the circle.
  • Pipe a rim of white frosting around the edge, and fill with lemon pudding/curd. (Or if you’re not using a lemon filling, spread the layer with frosting). Sprinkle with a chopped Lemon Oreo, and add your next cake layer on top. Repeat the process with your remaining cake layers.
  • Now you're ready to frost - here’s a video tutorial if you could use help at this step. https://youtu.be/Lwd6VE2SeVo
  • If you’d like more detail on the cake ring I used in the video, I cover that in this post. https://youtu.be/wKrTu2g-iHs
  • (If you plan to add a drip, place the cake into the freezer for about 20 minutes to set the frosting and get the cake cold enough to set the drip.)

Cake drip & Decorating

  • Place heavy cream and white chocolate chips in a microwave-safe bowl, and microwave on 50% power in 30-second intervals until smooth, stirring in between.
  • When your ganache has cooled to a moderate temperature – it should feel slightly warm but still be fairly liquid – add drips to the top edge of the cake using a piping bag or spoon.
