Step 1:

1 stick butter
16 oz. can Hershey's syrup
4 eggs
1/2 tsp. salt
1 c. sugar
1 tsp. vanilla
1 c. flour

Step 2:

1 c. sugar
1/2 tsp. vanilla
1/3 c. flour
1 c. butter
1 c. milk
1/2 tsp. peppermint extract
few drops green food coloring

Step 1: Combine all ingredients and pour into a jelly roll pan.

Bake at 350°F for 20 to 25 minutes. Cool completely.

Step 2: In a heavy bottom pan, bring to a boil flour and milk; cook over low heat until thick. Stir constantly so it doesn't scorch. Cool completely. Stir together sugar, butter, peppermint extract, vanilla and a few drops food coloring (a little goes a long way).

Add flour mixture gradually to sugar mixture in small amounts, beating constantly until the consistency resembles whipped cream. Spread over brownies and refrigerate.

Melt 2/3 cup chocolate chips with 2/3 cup butter. Mix well and spread over brownies while chocolate is still warm. Refrigerate until serving time.
