I got this recipe years ago from some friends in Utah. I LOVE it. Pioneer Woman recently posted a similar recipe on her website.
1/2 C. Butter (softened)
1/2 C. Brown Sugar
Cream together then add:
2 C. Flour
2 C. Oatmeal
1 tsp. Baking Soda
1 tsp. Salt
1 tsp. Vanilla
After mixing, press 1/2 of mixture onto edged 9x13 (or slightly bigger) cookie sheet and bake 8 minutes @ 350*.
Remove from oven & sprinkle on top:
1 C. Semi-sweet chocolate chips
1 C. Butterscotch chips
1 C. Chopped pecans or walnuts
Drizzle over top:
1 Jar butterscotch or caramel ice cream topping + 3 TBSP flour.
Then crumble remaining flour mixture over top and return to oven & bake 15-20 more minutes (still 350*).
