Raspberry Mascarpone layer cake

When BBC Lifestyle asked me to design a “pink bake” in honour of Breast Cancer Awareness month in correlation with their fantastic series, The Great South African Bake-off, I jumped at the chance. I knew exactly what, and for who, I would design said pink bake.

My mom passed away in December 2005 from breast cancer and I knew that there would be no better person to dedicate a cake to. And knowing that I was baking this cake  in honour of my mom, I knew it had to be completely over-the-top and just too much. Because my mom didn’t believe in less is more. She believed in more swirls and curls, more pink, more glitter, more fun, more laughter and more love. And so I wanted to design and decorate a cake that would say all of that. I think I succeeded, don’t you? There ain’t nothing quiet about this cake. 😉

Raspberry Mascarpone layer cake

I decided on my classic lemon sponge layered with luscious whipped raspberry mascarpone filling. And then came the excess. Whipped buttercream in all shaded of pink were swirled and piped onto the cake then finished with a white chocolate drizzle, sugar pearls, sparkles and all the pink glitter.

Of course, the decorations are completely optional and the cake itself is seriously perfection. The lightness of the filling works so well with the lemony cake and is a combo I revert back to often. It’s light, fruity and just a little indulgent.

for the cake

  • 3 cups cake all purpose flour
  • 3 teaspoons baking powder
  • 1 teaspoon salt
  • 2 cups plain Greek yoghurt
  • 4 eggs
  • 1 teaspoon vanilla extract
  • 1 cup canola oil
  • cups caster sugar
  • juice and zest of 1 lemon

for the filling

  • 1 x 250g approximately 9oz tub mascarpone, room temperature
  • ½ cup whipping heavy cream
  • ¾ cup icing/powdered sugar sifted
  • cups fresh raspberries

for the whipped buttercream frosting

  • 250 g 2 sticks unsalted butter, softened
  • 500 g 1lb icing/powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • 2 tablespoons milk

for decorating

  • Sprinkles of your choice


  • Pre-heat the oven to 180°c and grease and line two 21cm diameter, 10cm deep cake pans with baking paper.
  • Sift together the flour, baking powder and salt and set aside.
  • IN a separate bowl, combine the remaining ingredients and mix well.
  • Pour the egg and oil mixture into the dry ingredients and mix to combine.
  • Pour the batter into the prepared cake pans and bake for 30-45 minutes or until a skewer inserted comes out clean.
  • Remove from the oven and allow to cool before turning out onto a wire rack.
  • For the filling, whip the mascarpone until smooth then add the cream and whip until soft peaks form. Add the icing sugar and raspberries and whip until the raspberries are broken up and incorporated. Place in the fridge until ready to assemble.
  • For the buttercream, whip the butter until very pale (approximately 2 minutes) then slowly add the icing sugar.
  • Whip until light and fluffy then add the vanilla and the milk (the milk both thins the buttercream a little and adds to the fluffiness).
  • To assemble the cake, level off any unevenness from the cakes then sandwich together with the whipped raspberry mascarpone filling.
  • Decorate with the buttercream and serve.


For this cake, I doubled this recipe to result in a 4 layer cake.

  1. Hi Alida,

    I am attempting my first layer cake using your recipe. The decorating on the top and sides (using the piping bag) is it buttercream?
    Thank you!

  2. Alida, this is a beautiful cake that I have been eyeing for a while ))) can you please tell me if you colored the buttercream frosting with food coloring or raspberry juice? Also, are seeds from raspberries noticeable in the filling? Thanks so much in advance!

    1. Your Mother would be so proud! What a truly gorgeous show stopper cake! I can’t imagine how delicious is was! ???

  3. I pinned your beautiful and delicious sounding cake and hope to find an occasion for which to make it soon. One question: In Canada, all purpose and cake flour are different, do you mean you could use either one in the same amount? Thanks for the recipe inspiration.

    1. Cake flour is a little “Softer” than all purpose but if you can’t find cake flour, all purpose is perfectly fine. As long as you don’t use bread/strong flour, the cake will turn out perfectly.
