Chocolate Waffle-Brownies

These are easy for a quick, yummy, rich treat!  Make sure to seal left-overs because they dry out quickly.

1 cube butter, melted
6 Tbl. cocoa powder
3/4 cup sugar
2 eggs
1 cup flour
1 tsp. vanilla
1/8 tsp. salt

Mix cocoa powder and sugar into melted butter.  Add egg. Mix in flour, vanilla, and salt.  Beat well. Bake in hot, pre-heated Belgian waffle-maker.  Could frost with chocolate frosting, but not necessary.
