2 cups packed brown sugar
5 oz evaporated milk
1/2 pound butter
2 cups powdered sugar
1 cup walnuts
1/2 teaspoon vanilla
1/2 teaspoon maple flavoring
Butter a 9x13-inch pan and set aside. (9x13 will produce very thin fudge. use a smaller pan if you like thicker pieces.) lining the pan with foil or paper and buttering that makes cutting and removing much easier.
n a medium saucepan, combine sugar, butter and milk. Bring to a boil over medium heat. Reduce heat very slightly and boil 10 minutes while stirring constantly. No longer! (I didn't stir constantly. I was fairly good about it, but I left it every now and then and that turned out to be ok.)
Remove from heat and add powdered sugar, vanilla and maple flavoring. Mix thoroughly with hand mixer on medium until thick and glossy - just a couple of minutes. Fold in walnuts and pour in prepared pan.
Note: This recipe also doubles easily. For thicker fudge double and still use the one pan.
