If you really want to make these cookies happen, you have to first make the handcrafted toffee. Have this set aside and broken into small pieces to make up a half-cup. You'll also need to prepare your pretzels by chopping them up, and measuring one cup.
Preheat your oven to 350 degrees. Cream the butter. Add brown sugar, granulated sugar, baking soda, coarse salt, vanilla extract and optional vanilla bean powder
Add eggs, and combine.
Add all of the flour, and combine.
Add all of the chocolate, toffee and pretzels. You may want to add one at a time.
Your cookie dough is set. Work into pucks to bake, for 9-11 minutes - depending on your oven - or chill the dough in the fridge for 30 minutes first. You can bake all of your cookies at once, or chill the dough in the fridge for up to 4 days. The dough can be in the freezer for up to a month.
The toffee in the cookies may "run" in the baking process, but this is not a problem. The toffee can easily be worked back into the cookie so that they set nice and round as they cool.
