Brown Butter Toffee Blondies

What is brown butter I hear you ask? Brown butter is simply butter that has been cooked until it turns golden brown in colour. The butter takes on a nutty flavour which works well in these Toffee Blondies.
I found the recipe in Martha Stewart's Cookies.
Ingredients:-
1 1/4 cups unsalted butter (at room temp)
2 1/4 cups plain flour
1 1/2 teaspoons baking powder
1 1/2 teaspoons salt
2 cups packed light brown sugar
1/2 cup granulated sugar
3 large eggs
2 1/2 teaspoons vanilla extract
1 cup chopped walnuts
1 cup toffee bits

I had bought these toffee bits in America on a recent visit and had been waiting to find a recipe to use them in. You could use chunks of regular toffee as a substitute.

Method:-
1. Pre-heat oven to 350 degrees fahrenheit / 180 degrees centigrade / Gas Mark 4. Grease and line a 9 inch x 13 inch baking tray with greaseproof paper. Grease the paper again and flour lightly.
2. In a saucepan over a medium heat melt the butter until it turns a golden brown colour. Keep an eye on the pan to ensure you do not burn the butter. Remove from heat and allow to cool.
3. In a bowl whisk together the flour, baking powder and salt.
4. Using an electric mixer, combine the browned butter and both sugars. Add eggs and mix until light and fluffy. Add the vanilla and mix until combined. Add the flour mixture, walnuts and toffee bits. Mix thoroughly and pour mixture into pan.
5. Bake until cake tester inserted into the centre comes out clean - about 35 - 40 minutes. Transfer to wire rack and allow to cool before cutting into slices.

This is what the mixture should look like when you mix the butter with the sugars.

Mmm, just out of the oven. The recipe was delicious. I couldn't wait for the blondies to cool so had a couple of slices warm drizzled with cream. Okay, drenched with cream. Yum Yum. The next day the blondies tasted even nicer. Like a really rich chewy toffee cookie.
