Mrs Fields Authentic Brownie Recipe

This recipe comes from my mum's friend who comes from California. She got the recipe from a friend who worked in a Mrs Field's store back in the 1980's and had to bake a huge batch everyday. I am told that this is the authentic recipe!!!

• Ready In: 42 mins
• Serves: 20

Ingredients

• 1⁄2 cup butter
• 2  cups sugar
• 1⁄2 cup  cocoa
• 4  eggs
• 1 1⁄2 cups flour
• 2  teaspoons vanilla
• 1  cup  semi-sweet chocolate chips

Directions

1. In a large bowl beat the butter, sugar and cocoa until combined, not creamed.
2. Add the eggs one at a time, beating to just combine after each addition.
3. Add the flour, vanilla and half the choc chips and stir until just combined. Don't over mix or the brownies will be tough.
4. Pour the mixture into a greased 9x13 inch pan.
5. Pour the remaining choc chips over the top, getting a little everywhere. Use your hand to gently press the choc chips into the batter so they don't burn.
6. Bake at 350oF (160oC) for 32 minutes.
7. Cool for one hour, then place in the fridge until chilled.
8. Do not slice or eat until the next day - this is VERY important.
