How to Make It
Preheat the oven to 425°. Line a baking sheet with parchment paper or a silicone baking mat.
Lay the bacon on the prepared baking sheet and bake in the oven for 15-20 minutes, or until the bacon is quite crispy, turning half way. Remove from the oven, carefully pour off the bacon fat and reserve it for another use. Set the bacon aside to cool.
Once cool enough to handle crumble the bacon into small pieces.
Reduce the oven temperature to 350°.
In a large mixing bowl cream the butter, sugars and eggs with an electric mixer until well combined, about 2 minutes. Add the flour, baking soda, vanilla, sea salt and cinnamon and mix until just combined. Add the oats and crumbled bacon and stir until combined.
Drop by heaping tablespoons onto an ungreased baking sheet, 9-12 cookies per sheet depending on the size of your cookie sheet and how big you make your cookies.
Bake the cookies for 12-15 minutes, or until they are slightly brown along the edges but still soft in the center.
Remove from the oven and let cool on the baking sheet for 5 minutes then transfer them to a baking sheet to finish cooling.
