A friend gave me this recipe a number of years ago. She said it came from Betty Crocker. It's quite easy to make, just involves a lot of stirring. Also, you need to work quickly once you put the warm butter/sugar mixture in the pan. If you are too slow putting on the chocolate chips, they will not melt. If that happens, and you are using a glass pan, you can run it in the microwave for 10-15 seconds to help melt the chips. I used Hershey's dark chocolate chips this year, which turned out extra yummy!
from Betty Crocker
1 cup chopped pecans
¾ cup brown sugar (packed)
½ cup butter
½ cup chocolate chips
Butter a 9x9 or 8x8 square pan. Spread pecans in pan.
Heat sugar and brown sugar to boiling, stirring constantly. Boil over medium heat for 7 minutes, stirring constantly. Immediately spread mixture evenly over nuts in pan.
Sprinkle chocolate chips over hot mixture and cover with a baking sheet so the heat will melt the chips. Spread the chocolate evenly over candy mixture.
While hot, cut into squares. Chill until firm. Store in refrigerator.
