Preheat oven to 350f. Prepare a baking sheet or two by lining with silicone baking mats or parchment paper.
In the bowl of your stand mixer, beat 1 ⅓ cup melted butter and 4 cups brown sugar until completely combined.
Add in 4 eggs at a time and then ¼ cup hot water, beating well after each addition.
In a large bowl, whisk 5 cups all purpose flour, 2 teaspoons baking powder, 2 teaspoons baking soda, and ¼ teaspoon salt until well combined.
Slowly add the dry ingredients to the wet ingredients beating well to combine.
Stir in 1 ¼ cups semi-sweet chocolate chips, ¾ cup Skor toffee bits, and 1 cup chopped cooked bacon until they are well distributed.
Using a cookie scoop, or a teaspoon, scoop cookie dough and drop it onto the baking sheet, spacing a couple inches apart to account for spread.
Bake at 350f for 12-14 minutes.
Allow cookies to rest on the baking sheet for a minute or so after removing from the oven, before removing them and cooling on a wire cooling rack.
Store in an airtight container for 4-5 days.
Notes
Make ahead:
If you want to freeze cookie dough, scoop it into balls on to a cookie sheet lined with parchment paper, then place it in the freezer until balls are frozen enough to transfer to a ziplock bag for later use. To bake them; remove balls from the freezer and place them on a baking sheet to thaw while the oven preheats. Bake at 350f for 12-14 minutes.
To freeze baked cookies:
Line cookies on a wire cooling rack and place in the freezer until cookies are frozen, then place frozen cookies into a freezer ziplock bag. To serve: remove cookies from the freezer and thaw on a wire cooling rack for 30 minutes or until room temperature.
