I like these because I usually have all ingredients on hand.
1 1/2 c flour 1/2 tsp salt 2 tsp baking powder 2 eggs 1/2 c butter 1 tsp vanilla 1 c sugar 1/2 c brown sugar 4 chopped Heath Bars or about a half bag of Heath Toffee Bits (found in baking aisle near choc. chips)
Cream butter with the two sugars. Add eggs and vanilla. Beat until fluffy. Blend in dry ingredients. Stir in Heath pieces. Spread over well greased 9 X 13 baking pan. Bake at 350 degrees for 25-30 minutes. When cool, cut into bars. They are ooey gooey, not crisp.
