Awesome butterscotch brownies!

1 lb White Chocolate Chips
6tbsp unsalted (sweet) butter
3 eggs
3/4 light brown sugar
1 1/2 c self-rising flour
1 1/2 c walnuts, chopped
1 tsp vanilla

1. Preheat the oven to 375. Line the base of 1 11/7in shallow tin pan with baking parchment. Lightly grease the sides. Melt 3.5 oz of the chocolate chips with the butter in a bowl set over a pan of hot water. Leave to cool slightly.
2. Put the eggs and brown sugar into a large bowl and whisk well, then whisk in the melted chocolate mixture.
3.Sift in the flour into the bowl and gently fold in along with the chopped walnuts, vanilla and the remaining chocolate chips. Be careful not to over mix.
4. Spread the mixture out in the prepared tin and bake for about 30 min. Or until risen and golden brown. The center should be firm to the touch but will be slightly soft when it cools down.
5. Leave to cool in the tin, then cut into twelve bars when the brownie is completely cool.
