  • ½ tbsp pure vanilla extract

Method

Raspberry Puree

  1. Combine the raspberries and honey in a small saucepan over medium low heat.
  2. Cook the raspberries, mashing and stirring occasionally, until the mixture is reduced by half and very thick – about 15 minutes.
  3. Strain out the seeds by pushing the puree through a mesh sieve and then leave it to cool to room temperature.
  4. Reserve 2 tablespoons of the puree for decoration.

White Chocolate Heritage Frosting – Part One

  1. Whisk together the flour, sugar, salt, and milk in a small saucepan over low heat.
  2. Allow the mixture to come to a boil, whisking occasionally, and then boil for 1-2 minutes or until it is slightly thickened. It should have the consistency of a loose pudding.
  3. Pour the mixture into a container and refrigerate it while you complete the cake steps below.

Raspberry Ripple Cake

  1. Preheat the oven to 175°C (350°F) and grease, line, and lightly flour two 8” cake tins.
  2. Sift the flour, baking powder, and sea salt into a large bowl, give it a quick whisk, and set aside.
  3. In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar on a medium speed until fluffy and pale, then stir in the vanilla.
  4. Add the egg whites, two at a time, mixing for 30 seconds and scraping down the sides of the bowl in between each addition.
  5. Turn the mixer to a low speed and alternate adding the dry ingredients and milk: add one third of the flour mix, then one half of the milk, then the second third of the flour mix, then the second half of milk, and finally, end on the third portion of flour. Give the batter a scrape and one final 10 second whizz up.
  6. Remove 250 grams of the batter into a separate bowl and fold in the large portion of raspberry puree.
  7. Take one half of the vanilla cake batter and divide it between the two cake tins.
  8. Take one quarter of the raspberry batter and make three dots of batter on top of the vanilla batter in the tin. Repeat this step with the second cake tin.
  9. Divide the remaining vanilla batter between the two cake tins, taking care spread it evenly over the raspberry batter, not all in one dump or the swirl won’t work.
  10. Divide the remaining raspberry batter between the two cake tins, dotting it in as in step 8.
  11. Using a butter knife, swirl the batter in the cake tins in a vertical “M” formation. Rotate the cake tins 90° and repeat the swirling motion. Repeat this step twice more.
  12. Tap the cake tins lightly on the counter to level the batter and then bake them for 24-27 minutes or until a toothpick comes out clean and the sponges spring back when touched.
  13. Allow the cakes to cool in the tins for 10 minutes, then remove them to a wire rack to finish cooling completely.

White Chocolate Heritage Frosting – Part Two

  1. While your cakes are cooling, finish the frosting by adding the butter to a clean stand mixer fitted with the paddle attachment. Beat the butter on high for 5 minutes, or until the butter is fluffy and pale.
  2. Decrease the speed to medium and drop in the cooled flour pudding 1 tablespoon at a time. Once all the pudding is added, increase the speed to high and beat until super fluffy.
  3. Lower the speed to medium and very slowly drizzle in the cocoa butter at the side of the bowl. Give it another good whizz and then cover and refrigerate until your sponges have completely cooled. This will allow the frosting to firm up a bit if it’s become loose from the cocoa butter.

Assembly

  1. If necessary, level your cakes using a serrated knife or cake leveler so there are two even layers.
  2. Choose a bottom layer and place it on a decorating table or cake stand. Plop a half cup of frosting onto the cake and smooth it out to the sides. Create a slight indentation in the middle for the raspberries, leaving about half an inch along the outer rim.
  3. Place the raspberries in a single layer inside the frosting circle. Place the second layer of cake on top of the raspberries and press down gently to secure it.
  4. Use the remainder of the frosting to frost the top and outside of the cake.
  5. To create the raspberry smear, dot teaspoon sized amounts of the reserved raspberry puree all over the sides of the cake. Using a cake scraper, smear the raspberry dots into the cake by holding the scraper next to the cake, just brushing it, and gently turning the cake table or stand. Repeat this until you are happy with the level of smear.
  6. Top with fresh raspberries if desired.

Notes

Both the white chocolate heritage frosting and raspberry puree can be made up to 3 days in advance. Bring to room temperature before using.
