It was D's first time too.
I also found them quite hard to photograph, still here they are for you to get an idea of what they look like.
Brazil Nuts and Banana Blondies
100g unsalted butter
200g good white chocolate
225g caster sugar
1 egg, beaten
1 teaspoon vanilla extract
200g plain flour¼ teaspoon baking powder
75g Brazil nuts, roughly chopped
Preheat oven to gas mark 5. Line the base and sides of a 8 inch square baking tin with parchment paper.
Melt the butter and white chocolate in a double boiler or heatproof bowl over a pan of hot water, making sure the bowl is not touching the water. Take off the heat.
Mash the bananas in another bowl and mix in the sugar, the egg and vanilla. Add the melted chocolate mixture and stir until smooth. sift in the flour and baking powder over the mixture, then fold in, together with the chopped nuts.
Scrape the mixture into the prepared tin and bake for 40 - 45 minutes until golden on top, with a slight wobbly middle. Test with a skewer: its should come out with a crumb, not gloopy. Place the tin on a wire rack and leave to cool until cold. This recipe is adapted from Tamasin Day-Lewis who in turn adapted it from Dan Lepard.
