Preheat the oven to 180°c (160 fan/ 350 °F/ Gas 4) and line a 20cm square baking tin with baking paper.
In a large mixing bowl beat together the melted butter and sugar until pale and fluffy.
120 g Butter, 100 g Granulated Sugar, 50 g Light Brown Sugar
Add the egg and vanilla extract and mix in.
1 Egg, 2 teaspoon Vanilla Extract
Fold in the flour, baking powder and salt.
130 g Plain Flour, ½ teaspoon Baking Powder, ¼ teaspoon Salt
Stir in the dried cranberries and white chocolate chips.
125 g Dried Cranberries, 125 g White Chocolate Chips
Spoon the mixture into the prepared tin and bake in the oven for 25-30 minutes. The blondies may look a bit underbaked when you take them out of the oven but they will set further on cooling. If they have started to pull away from the edge of the tin they are ready!
Cool completely (you can speed this up by placing the tin in the fridge), then drizzle with the melted white chocolate and scatter over more dried cranberries and chocolate chips. Leave the chocolate to set before slicing into bars.
50 g White Chocolate, 25 g Dried Cranberries, 25 g White Chocolate Chips
