Preheat oven to 350 ℉. In a mixing bowl combine peanut butter, sugar, egg and vanilla, beat lightly until just blended (do not over mix). Mix in baking soda. Add toffee bits and chocolate chips. Line 9x9 inch pan with foil, pour mixture into pan and smooth with spatula. Bake for 20-22 minutes, cool and cut into bars.
NotesThat's right there is no flour in these.
