Brown 1/2 cup of unsalted butter. Melt butter over medium high heat until it is completely melted. Lower the heat to medium low and cook until brown bits start to appear at the bottom. Remove from the heat and set aside.
Add 1 tbsp of earl grey tea to a spice grinder or food processor. Pulse until it is broken down into powder and add to a bowl.
Add 1/2 tsp of ground cinnamon, 1/2 tsp ground cardamom, 1/4 tsp of ground ginger, 1/4 tsp of ground star anise, 1 cup + 1 tbsp of all purpose flour, 1/2 tsp of baking soda, and 1/4 tsp of salt to the bowl. Mix until combined and set aside.
Add browned butter, 1/4 cup light brown sugar, 1/4 cup dark brown sugar, and 1/4 cup granulated sugar to a bowl or the bowl of a stand mixer. Mix until combined.
Add the egg and 1 tsp of vanilla extract. Mix for 3-5 minutes until the mixture turns a light brown color.
Add the dry ingredients from step 3 to the bowl and mix until just combined.
Lastly, add 2 oz of dark chocolate, 1/2 cup of candied pecans, and 1/4 cup of toffee bits. Mix until just combined.
Cover and let the cookie dough chill in the fridge for at least 1 hour.
While the dough is chilling, preheat the oven to 350 degrees F (177 degrees C).
Prepare 2 baking sheets by covering them with parchment paper.
Using a medium cookie scoop (~2 tbsp), scoop the dough onto the prepared baking sheets. Make sure they are 2 inches apart.
Bake for 14-16 minutes.
After baking, let the cookies cool on the baking sheet for 10 minutes. Transfer to a cooling rack to cool completely.
