    • 1 tsp Baking soda
    • ¼ tsp Salt
    • 2 Eggs separated
    • ½ cup Sour cream
    • 1 tsp Vanilla bean paste or 2 tsp vanilla extract

    Vanilla buttercream

    • 1 cup Butter room temperature, unsalted.
    • 4 cups Powdered sugar
    • ½ tsp Salt
    • 1 tsp Vanilla extract or vanilla bean paste
    • ¼ cup Milk or water

    Simple syrup

    • ½ cup Sugar
    • 1 cup Water
    • 1 tsp Lemon juice

    Instructions

    Cake batter

    • Preheat the oven to 325°F /165°C/ Gas Mark - 3
    • Grease and line 2 x 6-inch round cake pans with parchment paper.
    • Dry ingredients - Sift together the flour, baking powder, baking soda, and salt.
    • In the bowl of a stand mixer with the paddle attachment, cream the butter, sugar, and oil. Whip for 2 to 3 minutes until light and fluffy.
    • Next add the eggs, one at a time. Followed by the vanilla bean paste or extract.
      Pro tip- adding eggs one at a time will prevent the eggs from curdling. If the batter does curdle just add a tablespoon of flour to help stabilize it.
    • Next, add the flour and sour cream in three batches. Combine well but do not over mix.
      Pro tip - we do not want to activate the gluten in the flour so work gently once you add the flour.
    • Pour the cake batter into the prepared cake pans. Bake on the middle rack for 20 to 25 minutes or until a skewer inserted in the center comes out clean.
      Pro tip - using baking/ cake strips for your pans will prevent a dome and excess caramelization around the edges which looks better for layer cakes.
    • Cool in the pan for 10 minutes then invert onto a cooling rack to cool completely.
      Pro tip - always cool cakes completely before decorating otherwise the frosting will melt on warm cakes.

    Vanilla buttercream

    • In the bow of a stand mixer with the paddle attachment, cream the butter until light and fluffy.
    • Then, add the salt, and powdered sugar one cup at a time. Once all the powdered sugar is in add the water or milk and vanilla extract.
    • Continue to whip for 2 to 3 minutes until the buttercream is pale but light and fluffy.

    Sugar Syrup

    • To prepare the simple syrup, boil the sugar, water, and lemon juice in a saucepan over medium heat. Once all the sugar is dissolved, boil a minute more - then cool completely.

    Assemble

    • Using a bread knife or cake leveler, level each cake layer by cutting the domes off. Brush each layer with simple syrup.
      Pro tip - Watch a video - how to level, torte, and fill cake like a pro.
    • Place the first layer on the cake board or cake stand. Add a dollop of buttercream and spread evenly with an offset spatula. Then, place the second layer on top. Chill the cake for 15 minutes.
      Pro tip - chilling the cake will help hold the two layers together and prevent them from moving while frosting the outside.
    • Add more frosting on the top and sides of the cake. Smooth the buttercream as best you can.
      Pro tip - an offset spatula for the top and a straight-edged spatula for the sides of the cake does a better job of smoothing. You can also dip a bench scraper in warm water for final smoothing
    • Transfer any remaining buttercream to a piping bag with a piping tip. Pipe a border on the top and bottom of the cake. Alternatively, this cake can be coved with fondant as well.
