This scrumptious custard sponge slice has a sneaky layer of custard between the two layers of cake, making it that extra bit special. Even better, it uses a packet cake mix so it’s a breeze to whip up.
Ingredients
- 1 pkt vanilla cake mix
- 2 eggs
- 2/3 cup milk
- 60g butter
For the custard
- 1/4 cup custard powder
- 2 cups milk
- 2 tbs caster sugar
For the topping
- 20g butter, melted
- 1 tbs caster sugar
- 1/2 tsp cinnamon
Method
-
Step 1Preheat oven to 160C. Grease a 27cm x 18cm slice tin and line it with baking paper.
-
Step 2Prepare cake with eggs, milk and butter according to packet instructions. Pour half the batter into the prepared tin.
-
Step 3Make custard by whisking custard powder into 1/4 cup milk to form a smooth liquid. Add the remaining milk and sugar. Whisk over gentle heat until just simmering, then continue stirring for another minute until custard has thickened.
-
Step 4Pour custard over cake batter in slice tin and spread out evenly. Top with remaining cake batter and smooth the surface. Bake for 35 minutes. Brush melted butter over hot cake then sprinkle over combined caster sugar and cinnamon.
