Grease 2 pizza pans (12 or 13 inch pans). Preheat oven to 325 degrees.
Melt margarine. Stir in cocoa. Mix sugar and eggs in mixing bowl. Stir in margarine and cocoa. Add vanilla, flour, and salt. Spoon half of the batter into the greased pizza pan. This recipe makes 2 brownie pizzas. Cook one pizza at a time. (Unless you have 2 ovens.)
Bake 17 minutes. Let cool completely.
Frosting
Combine frosting ingredients and mix well until smooth. Add enough food coloring to get your frosting as dark as you want it for your pizza sauce. Frost cooled pizza. Don’t go all the way to the edge so that the brownie will show for your pizza crust. This will frost both pizzas.
Toppings
Shred your almond bark with a cheese grater to look like mozzarella cheese. Sprinkle it over the frosting and then add your pizza toppings. Add any other fun toppings to your liking!
