Kick the tires and light the fires to 350 degrees.
Put the butter and sugars into your mixer and whip them until they are fluffy.
Add in the eggs and vanilla and whip them again until they are fluffy.
Mix in the flour/baking soda/salt until well combined.
Add in the toffee bits (try not to eat them all before they hit the batter, it's hard, I know) and combine them.
Drop by rounded teaspoon onto a well greased cookie sheet and pop into that 350 degree oven. The toffee bits like to stick to the sheets, just warning you.
Bake for 9-11 minutes until they are lightly browned, then let them cool on the sheets. Then you have to take a flipper to get them off if they have stuck to the sheets.
