1/2 cup vegan butter
1 teaspoon vanilla
1 cup cocoa
3 cups powdered sugar (or replacement: http://vegweb.com/index.php?topic=6327)
1/3 cup walnuts, chopped, optional
1. In a medium sized saucepan, melt the margarine over low heat. Once butter is melted, puree with avocado in food processor or blender until perfectly smooth. Be sure there are no chunks of avocado left.
2. Return mixture to saucepan over very low heat and add the rest of the ingredients, except the walnuts, adding the powdered sugar a portion at a time.
3. Once all the sugar has been added, the mixture should be thick. Add walnuts if desired, and transfer to a loaf pan. Refrigerate until firm. Now, be patient! If you don't let it firm up, you won't be able to slice it up into squares.
You can dazzle it up by sprinkling powdered sugar and nuts on top if you wish. Really its endless what you can do! Have fun!'
