Melt 1/2 cup semisweet chocolate chips (real chocolate, not chocolate flavored chips) with 1 stick of butter or margarine (not the soft spread). I use the microwave, but it can be done on the stove over low heat.
1/4 cup flour
1/4 cup cocoa
1/2 cup brown sugar
1/2 cup sugar
1 teaspoon vanilla
1/2 cup pecans or walnuts (optional)
Spread on a sprayed or greased 8x8 baking pan. Bake at 350 degrees for 40 minutes.
To test for doneness, an inserted toothpick will come out crumble-moist. Do Not overbake. Cool before cutting.
Now you're ready to enjoy a chocolate delight.
