2 Tbsp (30g) unsalted butter
1 tsp vegetable or canola oil
1 juicy passionfruit, halved, plus extra to serve
½ tsp vanilla extract
1 egg yolk
2 Tbsp white sugar
4 Tbsp plain flour (all purpose)
½ tsp baking powder
2 Tbsp white choc chips
Place butter in mug and melt in microwave for 15-20 sec.
Add oil, passionfruit pulp, vanilla extract and yolk, mix with fork.
Add sugar, flour and baking powder, mix until combined. Stir in white chocolate chips.
Microwave for 1½ minutes or until top is just set and skewer inserted into the middle comes out clean. It overcooks quickly, so it's better to take it out slightly early and pop back in for 10 sec increments if needed.
Serve with ice-cream and more fresh passionfruit.
