Avocado and Vanilla Bean Cake w Passionfruit Curd

Serves 12

As spring approaches and the blossoms are coming into bloom we automatically feel like this is something worth celebrating and without a doubt as the days are only becoming warmer and longer. Nothing sums up our mood more than our creative new avocado and vanilla bean cake with passionfruit curd. Yum!

The cake:
2 ½ medium sized avocados
1 tbsp lemon juice
¾ cup neutral vegetable oil
1 cup caster sugar
3 eggs
2 tsp vanilla bean paste
300g plain flour
50g ground almonds
½ tsp salt
1 tsp baking powder
1 tsp baking soda
½ cup greek yogurt

The frosting:
375ml cream
2 tsp vanilla bean paste
2 tbsp icing sugar
340g mascarpone

Extras to serve:
Passionfruit curd (see note below)
Chopped pistachios (optional)

Cake method:
Heat oven to 175c. Line two 8 inch tins with baking paper and spray lightly with oil.

Mash the avocado well till smooth, then add the lemon juice and stir through. Set aside.

In a stand mixer, beat the oil, sugar, and vanilla bean paste well until thick and creamy. Add eggs and beat again. Add the avocado and beat on low speed until incorporated.

In a separate bowl combine the flour, almond, salt, baking powder and baking soda and whisk together.

Gently fold the flour mix through the avocado mix stirring until smooth. Lastly add the yogurt and mix until just incorporated. Separate the batter evenly between the two prepared cake tins, leveling off the top with an offset spatula or back of a spoon.

Bake at 175 for 30-35 minutes, or until a cake tester comes out clean with no crumbs. Remove from the oven and leave to cool in the tins for 10 minutes before gently turning out onto a cooling rack, removing the baking paper, and allowing to cool completely before frosting.

Frosting method:
In a stand mixer, beat the cold cream and icing sugar with a whisk attachment until soft peaks form (don’t over beat, as the cream will turn grainy). In a separate bowl mix the mascarpone and vanilla, then add to cream and beat together quickly until just incorporated.

To serve:
Top one cake with half the frosting and gently spread toward the edges. Carefully position the second cake evenly over the first. Spread with the remaining frosting. Top with a few generous spoonfuls of passionfruit curd or fresh passionfruit (when in season) and a sprinkle of chopped pistachios. Best enjoyed on the day you make it. NOTE: You can buy curd at most supermarkets, but homemade curd doesn’t take long to make and is really worth the effort! If you’re keen to give it a try see the recipe below.

Small batch passionfruit curd:
100g caster sugar
1 whole egg, and 1 egg yolk
1 tbsp lemon juice
A pinch of salt
85g cold butter, cut into small cubes
1/3 cup of passionfruit pulp (frozen is fine and available from most supermarkets)

 

Avocado and Vanilla Bean Cake w Passionfruit Curd

Method

Method:
Set up a double boiler over a medium heat (use a pot filled with water and choose a  larger sized heat-proof bowl – just make sure the bottom of the bowl doesn’t touch the water at all). Whisk the sugar, egg, yolk, lemon and salt in the heat-proof bowl until it’s all fully incorporated. When the water in the pot comes to a boil, turn it down to a low simmer and place the bowl on top of the pot so that the steam from the water is gently heating the mixture. Add the butter and passionfruit pulp, and gently whisk as the mixture begins to heat and the butter melts.

Keep stirring regularly, and check that all the water in the pot underneath hasn’t evaporated away – just top it up with water from a boiled kettle if it’s getting low. After about 10 minutes, you should start to notice it thickening up – first around the outside of the bowl where it’s hottest, and will leave a bit of a ‘skin’. When you lift up your whisk you’ll also see that the curd that drips off stays on the surface for a few seconds before disappearing back into the mixture. At that point remove the bowl from the pot, and leave it to cool for 10 minutes before pouring it into a clean jar with a screw-on lid. The curd will continue to thicken as it cools. Keep it in the fridge, it stays fresh for around two weeks.
