Here is an easy recipe that has been a big hit at work:

Peanut & candy brownie pizza

1 (1 lb.5.5oz.) pkg. pillsbury traditional fudge brownie mix
1 cup mini marshmallows
1 cup m&m's
1/2 c. chopped peanuts
1/3 c. caramel ice cream topping

heat oven to 350. grease 12"pizza pan. prepare brownie mix according to pkg. directions. spread in greased pan.

bake at 350 for 30 to 34 minutes-do not overbake. Immediately sprinkle with marshmallows, m&m's, & peanuts. drizzle with caramel topping. cool completely-cut into wedges to serve. you could use the holiday m&m's and colored marshmallows for a festive look. I bake mine in a foli pizza pan-no messy clean-up!!haven't had any leftovers...
