Easy Brownie Mix
6 tablespoons cocoa
1/4 cup butter
1 cup sugar
1/2 teaspoon vanilla
1/4 teaspoon salt
1/3 cup flour
2 eggs

Preheat the oven to 325 degrees. Melt the butter and mix in the cocoa powder. Add the sugar, eggs, vanilla, flour and salt and mix well. Lightly butter a pan and sprinkle flour or cocoa until it’s covered.
Butter the baking pan lightly and sprinkle flour or cocoa over the pan until covered. This will help the mixture not to stick to the dish. Spread the brownie batter evenly in pan and put in oven for 35-40 minutes. When a tooth pick is inserted and it comes out clean the brownies are ready. Allow to cool until warm before cutting.

Spray a 9-inch baking dish with nonstick cooking spray. Heat the sweetened condensed milk and unsweetened chocolate in a medium saucepan together over medium-low heat until the chocolate is melted and the mixture thickens, about 10 minutes. Remove pan from heat, and stir in the graham cracker crumbs and half of the chopped walnuts. Spread in the prepared pan. Top with remaining walnuts. Chill until firm, 3-4 hours.
