Instructions

Instructions are for 12 servings. Please modify as needed.

Cake

  1. Preheat the oven to 365°F (185°C). Grease a springform cake pan (about 8 inches / 20 cm in diameter) with butter.
  2. Separate the eggs. Place the yolks in a small saucepan and set aside. In a large bowl, beat the egg whites with an electric mixer until soft peaks form. It takes a few minutes.
  3. Add the sweetener and continue whipping. Melt the butter and add the rest of the ingredients. Mix together quickly but don't whip for too long.
  4. Pour the batter in the cake pan and gently distribute the batter evenly with a spatula.
  5. Bake in the middle of the oven for 35 minutes or until a toothpick inserted in the middle comes out clean.
  6. Remove from the oven and allow to cool completely. If you're serving the cake the next day, cover with plastic wrap and place in the refrigerator to cool completely overnight.

Vanilla buttercream

  1. Combine the cream with the egg yolks in the saucepan over low heat, and whisk thoroughly. Add the rest of the ingredients, except the butter. Keep whisking until the cream thickens. Make sure the cream doesn't start boiling, because then you'll get scrambled eggs instead of vanilla cream, which we would like to avoid in this case. Turn off the heat.
  2. Divide the butter into smaller pieces and add to the cream. Stir until melted and evenly combined.
  3. Allow to cool. Place in the refrigerator to cool completely, preferably overnight.
  4. When ready to frost the cake, pour the vanilla cream in a large bowl and beat with an electric mixer until fluffy.

Assembling, frosting and decorating

  1. Slice the cake horizontally, so you get two, even, circular cake layers. Place the bottom layer on a nice cake stand.
  2. Spread the vanilla cream on the cake and top with the second layer.
  3. For the frosting, whip the cream until fluffy but not too stiff. Spread over the whole cake or use a piping bag if you're going for a more elegant look.
  4. Cut the strawberries into wedges or slices. Decorate the cake with the strawberries as you like. For an extra touch of summer, top with some beautiful flowers.

Tips

The end result is a compact but moist cake. The cake is built up with the buttercream vanilla filling and further height is achieved with the frosting and strawberries.

Feel free to vary the flavors by adding grated lemon zest or lime zest in the vanilla cream, and top with berries in season.

We do not recommend changing the serving size of this cake due as this may affect the required springform cake pan size and cooking time.

    Just tried this recipe for July 4th, and it was a hit! I need to try again though, because my cake was very thin (but nice and moist), and my butter cream was runny. All tasted great though and no one really knew what it was supposed to look like, and I even was asked by everyone there for the recipe, lol. So I guess it is forgiving...

    This cake was absolutely phenomenal! Loved by all and will definitely make again. The cake was a bit thin and tore when I cut it but under all that buttercream goodness and whipped cream you couldn’t tell. Thanks!

    Will you please edit your instructions more clearly. @3: Where do you add the sweetener to? To the yolks or egg whites and when do you add the egg whites. Do you fold it into... So confusing... More detailed instructions please. Thank you.

    The sweetener is added into the egg whites since the yolks are set aside to make the frosting.

    Is it possible that it wasn't allowed to cool and thicken long enough in the refrigerator?

    My cake came out very thin.
    I see many comments the cake is thin , can’t do two layers .
    Is there a possible reason ? What are all doing wrong ?

    The layers are pretty thin! If you prefer, you can cook this in an 8" springform pan for thicker layers. You may need to adjust the cooking time.

    I am sorry this turned out runny. It's definitely very creamy but shouldn't be runny. Next time you can try using less heavy whipping cream.
