You know you want one.
Melt 4 oz unsweetened chocolate along with 8 oz (one stick) unsalted butter over medium low heat.
Mix together in a bowl:
2 cups granulated sugar
2 tsp pure vanilla extract (Don't use the imitation stuff or I'll hunt you for sport.)
4 large eggs
Add the melted chocolate mixture to the sugar mixture and stir to combine. Add:
1 cup all purpose flour
3 tablespoons unsweetened cocoa (sift it first or it will be lumpy)
2 cups chopped walnuts
Stir it all together with a rubber spatula until just combined.
Line your 13 x 9 inch pan with foil and spray with pan spray.
Pour in your batter and spread it out to the edges.
Bake in preheated, 350 degree oven for 26 minutes or until a toothpick inserted into the center comes out clean.
When cool you can flip the brownies out of the pan (carefully), cut them into squares and eat the entire pan in a single sitting.
Blame it on the dog.
"Bad dog! Ate a whole pan of brownies I baked for my contract bridge party!"
"Edna and Mavis will be simply furious!"
