Ingredients
  

Strawberry Lemon Cake

  • 1 cup buttermilk (see note below on how to make buttermilk at home)
  • ¾ cup vegetable oil
  • ½ cup plain Greek yogurt
  • 3 eggs
  • cups granulated sugar
  • ¼ cup brown sugar
  • 2 teaspoon vanilla extract
  • 1 tablespoon lemon zest (from about 1 large lemon)
  • ½ cup lemon juice (from about 2 large lemons)
  • 3 ¾ cups plus 1 tablespoon all-purpose flour, divided
  • 2 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 2 cups fresh strawberries, diced
  • 1 cup strawberry jam

Strawberry Lemon Frosting

  • 2 cups unsalted butter softened overnight to room temperature (4 sticks)
  • 4 cups powdered sugar
  • ¼ cup lemon zest (from about 1 large lemon)
  • ¼ cup strawberry jam
  • ¼ teaspoon salt

Instructions
 

Prepare and Bake the Cake Layers

  • Preheat the oven to 350°F. Grease your 8-inch round cake pans.
  • This recipe can make either a four-layer cake. Grease as many cake pans as you have/need. I made a four layer cake and I have two pans, so I baked the first two layers, popped them out and let the pans cool for about 10 minutes, then I re-greased the pans and baked the second two layers. Keep any cake batter that you're not currently baking tightly covered in the fridge.
  • In a large mixing bowl, beat the buttermilk, vegetable oil, Greek yogurt, eggs, granulated sugar, brown sugar, vanilla extract, lemon zest and fresh lemon juice.
  • Add in the 3¾ cups of the flour, baking powder, baking soda and salt. Mix it all together with a large spoon or silicon spatula just until the batter is combined and you don't see any dry flour.
  • In a small bowl, toss the diced strawberries with 1 tablespoon of flour.
  • This helps coat the strawberries so they don't all sink to the bottom of the cake while it's baking.
  • Gently fold the flour-coated diced strawberries and the strawberry jam into the cake batter.
  • Divide the batter evenly into your four round baking tins. Bake for 30 to 35 minutes, or until a toothpick comes out clean.
  • Let the cakes cool for five minutes in the pans, then remove them and set them on a wire cooling rack to cool to room temperature for at least 2 hours.

Prepare the Frosting

  • In a stand mixer or in a large mixing bowl with a hand whisk, beat the softened butter for about 5 minutes, until it is soft and fluffy.
  • Add one cup of powdered sugar and beat it on a low speed until the sugar is incorporated. Continue beating in one cup of powdered sugar at a time until it's all mixed in and the frosting is smooth, fluffy and pale yellow.
  • Mix in the strawberry jam until it's incorporated.
  • If you feel like your buttercream is still too stiff, add 1 tablespoon of milk at a time and beat that in to help loosen your buttercream. The frosting should be stiff enough to stick on the sides of your cake without sliding down.

Assemble the Cake

  • Trim the caramelized edges off the four cake rounds. Trim the tops off the cakes so they are level.
  • Place the first cake layer in the center of a plate or cake stand. Spread out a few large dollops of the buttercream on top of the first layer.
  • Place the second cake layer on top of the buttercream, making sure this cake layer is centered on top of the first layer. Spread out a few more large dollops of the buttercream on top of the second layer. Repeat for the third and fourth layers of the cake.
  • Spread the remaining buttercream on the sides of the cake. Use a butter knife or a pallet knife to get the buttercream even and smooth on the top and the sides. Top with fresh strawberries & sliced lemons.
  • If you plan to transport this cake somewhere, refrigerate the cake for at least one hour, so the buttercream has time to set and harden a bit.

Notes

  • Homemade Buttermilk: Combine one tablespoon of lemon juice with one scant cup of milk. Let it sit at room temperature for 10 minutes to curdle slightly.
  • Storing: Cover any exposed cake slices with plastic cling wrap & store leftovers in the fridge. If you decorate your cake with fresh strawberries, the red color might bleed onto your buttercream, so I usually remove the fruit topping when storing it.
