Instructions
- Prepare the Sponge Cake:
- Preheat your oven to 350°F (175°C) and grease and flour an 8-inch round cake pan. Set aside.
- In a large mixing bowl, whisk the eggs and sugar together until light and fluffy.
- Add the lemon juice, lemon zest, and vanilla extract. Mix well.
- In a separate bowl, sift the flour, cream of tartar, and salt together. Gradually fold the dry ingredients into the egg mixture, mixing gently to avoid deflating the batter.
- Slowly pour in the melted butter and fold it in until just combined.
- Pour the batter into the prepared pan and smooth the top.
- Bake for 20-25 minutes or until the cake is lightly golden and a toothpick inserted into the center comes out clean.
- Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
- Prepare the Lemon Cream Filling:
- In a mixing bowl, whip the heavy cream with powdered sugar until soft peaks form.
- Add the lemon juice, lemon zest, and vanilla extract. Continue whipping until stiff peaks form.
- Assemble the Cake:
- Once the cake has cooled, slice it in half horizontally to create two layers.
- Spread a generous amount of lemon cream filling on the bottom layer and then top with the second layer.
- Spread the remaining lemon cream over the top and sides of the cake.
- Garnish:
- Garnish with fresh lemon slices or zest, and dust with powdered sugar if desired.
- Serve:
- Slice and serve chilled or at room temperature. Enjoy the light and refreshing flavors of this lemon cream sponge cake!
