Harriet's Cookies (Brown Sugar Shortbread Bars With Chocolate)

My mother has been making these since I was a child. I had no idea how easy they were until I asked her for the recipe. She got the recipe back in the 1960's from her friend Harriet. Few ingredients and delicious!

Ingredients

• 1  cup butter (2 sticks)
• 1  cup brown sugar

Directions

1. Cream the butter and brown sugar.
2. Mix in the egg yolk and vanilla.
3. Add the flour and salt.
4. spread in an 9 X 13 baking dish. I like to put parchment in the bottom of the pan.
5. Bake at 350° for 20-25 minutes.
6. Immediately after taking it out of the oven, put the chocolate bar on top to melt.
7. Spread the chocolate all over the bar (you can add tidbits on top of the chocolate - toasted pecans and Heath Bar bits are both good).
8. Cut diagonally.
