In the Kitchen Cupboard Bars we have M&Ms, KitKats, Caramello, Mars Bars, popping candy chocolate, chocolate chips, white chocolate and to top it all off, a chocolate spread swirl.
Preheat the oven to 180°C (350°F) and line a 9" baking pan with baking paper.
Beat the melted butter, sugar and brown sugar together until light and fluffy.
Add in the eggs and the vanilla extract and beat.
Add in the cornflour, baking powder and flour and mix until all combined.
Mix in all the confectionary.
Gently swirl through the Nutella (I find melting it helps).
Spread the mixture in the baking pan.
Place in the oven and bake for 25-35 minutes. Check the bars at 25 minutes the outside and top should be set but the middle slightly wobbly. If it is too 'underdone' for you, baking for a further 10 minutes.
Notes
You can replace any of the confectionery for your favourite chocolate bars.
