Step 1

Preheat the oven to 350°F. Lightly grease a rectangular 13x9x2 inch pan.

Step 2

In a 3-quart saucepan, gently combine the unsweetened chocolate and shortening over low heat until melted. Remove from heat. In the same saucepan, mix the sugar, vanilla and eggs into the chocolate mixture. Add the remaining ingredients and 1 cup of M&M'S Peanut Butter candies. Stir until combined.

Step 3

Spread the batter into the pan. Sprinkle with the remaining 1 cup of candies and press lightly. Bake until the brownies begin to pull away from the sides of the pan, about 30 minutes. Do not overbake. Cool completely, and cut into squares. Enjoy!
