- 60g butter
- 1 cup (160g) brown sugar
- 1 egg
- 3/4 cup (110g) plain flour
- 1/2 tsp baking powder
- 1/2 tsp salt
- 2 tsp Queen Organic Vanilla Bean Paste
- 80g butter
- 2/3 cup (100g) icing sugar
- 1 tsp Queen Organic Vanilla Bean Paste
Preheat oven to 160°C (fan forced) and grease and line a 15cm square baking tin so that the paper extends over the sides to form handles (to help remove the finished slice from the tin).
In a small saucepan, melt the butter over medium heat then remove from the heat, transfer to a medium bowl and leave to cool for 10 minutes.
Add the sugar, egg, flour baking powder, salt and vanilla and stir through until the mixture is smooth.
Spread the batter into the prepared tin and bake for 20-25 minutes. Remove from tin to cool completely before icing.
To make the icing, beat all the ingredients together in the bowl of an electric mixer until light and fluffy. Spread on top of the cooled slice.
