Ingredients
Slice
- 2 sheets of vegan-friendly puff pastry
- 1 cup caster sugar
- 1/2 cup vegan-friendly custard powder
- ¾ cup corn flour
- 4 cups of your favourite plant-based milk
- 2 tsp vanilla extract
- 60 grams of Nuttelex or vegan butter substitute/margarine
Icing
- 2 cups of icing sugar (sifted)
- 1 teaspoon Nuttelex
- Passionfruit pulp (about 1 passionfruit) – we keep a tin in the pantry for impromptu vanilla slice. Alternatively, if you don’t have passionfruit use 1 teaspoon of vanilla extract
- 1–2 teaspoons of water
Method
Slice
- Preheat oven to 200°C. Place the puff pastry sheets on lined oven trays. Prick with a fork and bake for 10–15 minutes at 200°C or until lightly browning on top. When you remove them from the oven, flatten them with a clean tea towel if they are too “puffy”, as you want them flat for the slice.
- Mix the caster sugar, cornflour and custard powder in a saucepan. Gradually add milk, whisking continually to ensure no lumps form.
- Add the Nuttelex/vegan butter, mixing continuously over medium/high heat until the custard is thick.
- Remove from stove top and add the vanilla.
- Let everything cool slightly. Place in a 22 cm square tin: first the pastry, then spread the custard evenly over the first sheet of pastry, then place the second sheet of pastry on top. Place in the refrigerator.
- Once completely cool, make the icing and ice the slice.
Icing
Place icing sugar, Nuttelex (vegan butter) and passionfruit pulp in a bowl and mix. Add small amounts of water at a time until you have a medium-textured spreadable icing. Spread evenly over the top of the cool slice. Only cut the slice when completely cool.
