Ingredients and substitutions for Passionfruit Cake
- Butter: The brown butter must be room temperature here to create the nice and fluffy base of the cake which allows more air to be whipped up and help the sugar begin dissolving. As butter loses approximately 30% moisture during the browning process, the weight of regular butter to make the browned butter for the cake was 200 grams / 7 ounces and for the frosting weighed 75 grams / 2.65 ounces.
- Sugar: Superfine or caster sugar gives our cake itโs sweetness without overly flavoring the cake allowing the vanilla to shine and the strawberries in between. You could substitute with raw sugar or half and half with brown sugar, though your cake would have slightly more caramel flavor. Icing or confectionerโs sugar is best here because it dissolves into the butter due to itโs incredibly fine texture.
- Plain flour: You don't need much and don't want to overwork the dough so you don't make these too stiff. However, you can substitute with self-raising flour which is most commonly found in
- Eggs: The eggs need to be room temperature here to bind with the butter and sugar as room temperature eggs allow more air into them giving our sponge that nice and light texture.
- Sour cream: Rich and creamy sour cream adds the necessary fat and moisture into the cake, though you could replace with Greek yogurt in equal measure.
- Passionfruit: Each whole fruit weighed around 40 grams and 2 whole passionfruit pulp with juice removed weighed 30 grams with 10 grams for juice. You could replace the juice in the cake with mango juice and top with slices of mango. Or stew or roast rhubarb and use that juice in the cake and top the frosting with the produce. Alternatively you could add vanilla extract to the cake and top with macerated berries.
- Cream cheese: The core of our creamy frosting is room temperature full fat cream cheese, this helps to ensure the frosting is spreadable.

You could add a whole passionfruit to the cake, if the seeds donโt bother you in baking. You could also replace the juice in the cake with mango juice and top with slices of mango. Or stew or roast rhubarb and use that juice in the cake and top the frosting with the produce. Alternatively you could add vanilla extract to the cake and top with macerated berries.
- Cake tin: A round spring form tin was used, however, a standard cake tin of similar size would also work well.
