Preheat oven to 350°F, or 325°F for a non-stick pan
Spray a 12 inch pizza pan with non-stick spray.
In a medium size sauce pan melt butter, sugar and unsweetened chocolate over low heat, stirring frequently, until all melted and smooth.
Add in vanilla and stir to mix.
In a large mixing bowl combine flour and salt.
Pour chocolate mixture in with the flour and thoroughly mix.
Add in eggs and mix until well incorporated.
Pour mixture in prepared pan and spread evenly.
Bake for 15 minutes, or until a toothpick inserted into the middle comes out clean. This is a very thin brownie so don’t overbake!
Remove from oven and place on a wire rack to cool completely.
To make the icing
With an electric mixer cream together butter and cream cheese.
Add in vanilla and mix thoroughly.
Gradually add in powdered sugar beating well after each addition, until all the sugar is mixed in and the icing is light and fluffy.
Spread the icing evenly across the cooled brownie.
Decorate with M&M’s and sprinkles. If you want to make a pattern or design with the M&M’s lay it out on the counter to get an idea for spacing so that you don’t have to rearrange icing covered M&M’s!
To serve- slice into 8 or 16 equal pieces and enjoy!
Cover with foil or plastic wrap to store.
Notes
*note- the pizza pan must have raised sides, a pizza stone will NOT work for this recipe.* If you want this to serve more people, make the slices smaller. This can also serve 16 people if you make the slices half the size.
