This recipe came from the Dec/Jan 97 issue of Taste of Home. This was the first time that this recipe was made and it is definitely a keeper.

In a mixing bowl, cream margarine and sugar. Add eggs and vanilla; mix well. Combine flour and cocoa. Add to the creamed mixture and mix well. Spread into a greased 13 x 9 x 2 inch baking pan. (If using T-fal pan, one doesn't have to grease) Bake at 350 degrees for 25 minutes. Cool completely. Dust with confectioners' sugar, if desired.
