BYU Mint Brownies, Baby!

These are the BEST. Helped me through many a night of gossiping, studying or...well, gossiping in college.
p.s. the frosting really makes these babies...feel free to substitute the brownie part for a mix or another favorite brownie recipe from scratch. They could be chocolatey-er, in my opinion.

2 Tbsp. honey
4 eggs
2 c. sugar
1 3/4 c. flour
1/2 Tbsp. baking powder
1/2 tsp. salt

5 Tbsp. margarinedash of salt
3 Tbsp. milk
1 Tbsp. light corn syrup
2 1/3 c. powdered sugar
1/2 tsp. mint extract
1-2 drops green food coloring

2. Prepare mint icing: Soften margarine. Add salt, corn syrup, and powdered sugar. Beat until smooth and fluffy. Add mint extract and food coloring. Mix. Add milk gradually until the consistency is a little thinner than cake frosting.
3. Spread mint icing over brownies. Place brownies in the freezer for a short time to stiffen the icing. Remove from the freezer and carefully add a layer of chocolate icing.
