Chocolate Maple Walnut Fudge

This is the yummiest chocolate fudge! All it is is the basic fantasy fudge recipe....you know it.....the one on the back of the small marshmallow cream. BUT...instead of vanilla I double the amount with maple extract, and topped it with walnuts!  Wow...it really made a difference in the taste!  Here is a copy of the fantasy fudge recipe just in case you don't have it.....

3 cups sugar
3/4 cup butter or 3/4 cup margarine
2/3 cup evaporated milk
8 -12 ounces chocolate chips 
1 (7 ounce) jar marshmallow cream
1 cup nuts (optional)
1 teaspoon vanilla

1 Mix butter, sugar and milk in a saucepan.
2 Heat until 230 degrees on a candy thermometer. Or if you do not have a thermometer, bring to a rolling boil, stirring constantly for 4 to 5 minutes. I NEVER use a thermometer, I always boil for exactly 4 minutes!
3 Remove from heat.
4 Stir in candy chips a little at a time until melted.
5 Stir in the rest of the ingredients.
6 Spread into a greased 13" by 9" by 2" pan.
7 Cool to room temperature.
8 Cut into squares.
