Toffee Squares - Cookie Recipe

For today, I wanted to share my absolute favorite Christmas Cookie recipe.  My mom has been making these cookies since I was little.  Not only are these my favorite, but they're my aunts favorite of mom's cookies as well.

TOFFEE SQUARES

1 cup Butter
1 Egg Yolk
2 cups Flour
1/2 cup Chopped Nuts
1 cup Brown Sugar packed (dark brown sugar is best)
1 teaspoon Vanilla
1 - 6 ounce package of Chocolate Chips melted

Cream butter and sugar.  Blend in egg yolk and vanilla.  Add flour and mix well.  Spread in greased 15 X 10 inch jelly roll pan.  Bake in moderate oven, 350 degrees for 15 to 20 minutes.  Remove from oven and immediately spread with melted chocolate and nuts.  Cut into 24 squares.

Enjoy!
