Peanut Butter Chocolate Brownies

Ingredients

180 g unsalted butter, chopped (6 1/3 ounces)
150 g dark chocolate chopped (5 1/4 ounces unsweetened chocolate)
1 3/4 cups caster sugar (superfine sugar)
4 large eggs lightly beaten
1 tsp vanilla extract
3/4 cup all purpose flour
1/3 cup cocoa powder (Barry's is the best)
50 g (1 3/4 ounces semisweet chocolate), chopped
1/2 cup peanut butter (I used smooth)

1. preheat oven to 325 F. Grease a 20 x 30 cm tin and line base and 2 long sides with foil or parchment paper. Sift flour and cocoa together.

2. Combine butter and chocolate in a medium saucepan, stir over a low heat until smooth (or place in large heatsafe bowl and melt in microwave on low heat in short bursts stirring well in between - I use the stovetop method). Transfer chocolate mixture to a large bowl and stir in sugar, eggs and vanilla. Once combined gently stir in flour and cocoa and the extra chopped chocolate.

3. Pour into the prepared pan. Drop small spoons of peanut butter into the chocolate mixture and swirl through to make a marble pattern with a knife.

4. Bake in over for 50 mins or until firm. Allow to cool in pan. Turn out and cut into squares.
