“Rhubarb and custard is an iconic flavour combination – whether you think of those boiled sweets (my parents used to adore these) or even just stewed rhubarb topped with fresh custard, the sweet tang you get from the rhubarb, combined with the lovely flavour of custard, it really is amazing,” says blogger and baker, Jane Dunn. “Add these delicious flavours to a blondie traybake and it wins everyone’s favourite bake!”

Rhubarb and custard blondies
Equipment
- Saucepan
- 23cm square baking tin
- Large bowl
Ingredients
- 175 g rhubarb
- 300 g white granulated sugar
- 2 tbsps water
- 200 g unsalted butter melted
- 3 eggs
- 125 g plain flour
- 75 g custard powder
- 200 g white chocolate chips or chunks
- 100 g custard
Method
- Chop the rhubarb into pieces, and add to a pan with 50g of the sugar and the water. Place over a medium heat, stirring occasionally, for about five minutes, or until the rhubarb softens. Set aside to cool.
- Preheat the oven to 180°C/160°C fan and line a 23cm square tin with parchment paper.
- Put the melted unsalted butter and remaining 250g sugar into a large bowl and beat until smooth. Add the eggs and beat until smooth, then add the plain flour and custard powder and beat until combined. Fold through the white chocolate chips or chunks.
- Pour the mixture into the tin and spread out evenly. Dollop the rhubarb mixture and custard over the top and swirl through slightly using a cake skewer or knife.
- Bake the blondies for 30–35 minutes, or until there is an ever so slight wobble in the middle. Leave the blondies to cool fully in the tin before cutting into 16 squares.
