Put all of the mini Heath Bars in a ziploc bag and crush them with a rolling pin. I like big and little chunks in my cookies, so I left some big pieces. Set aside.

Cream together the butter with both sugars. Cream until very light and fluffy, about 5 minutes.

Add the eggs one at time, and the vanilla. Scrape the bowl.

Add 2 cups of flour. Dissolve the baking soda in the hot water. Add the baking soda mixture, the last cup of flour, salt, and cream of tartar to the bowl.

Add the Heath Bars and mix until just combined.Using an ice cream scooper, add scoopfuls to a baking sheet lined with parchment paper.

Bake in a preheated 350 degree oven for 10 minutes. Let cool.
