In a large mixing bowl, stir together the brown sugar and melted butter until well combined. The mixture will be glossy and smooth.
Add the eggs and vanilla extract, mixing until fully incorporated.
Stir in the sourdough discard, ensuring there are no lumps remaining from the mixture.
Sprinkle in the baking powder, salt, and ground cinnamon, and stir to evenly distribute.
Add the flour, mixing until just combined, taking care not to overmix.
Gently fold in the instant oats and shredded coconut with a spatula until evenly distributed.
Introduce the chopped pecans and 1 cup of chocolate chips into the mixture, ensuring everything is well combined. Reserve an additional ½ cup of chocolate chips for topping.
Scoop the batter into the prepared baking pan, spreading it evenly to the edges. Sprinkle the top with the reserved ½ cup of chocolate chips.
Bake at 350℉ (180℃) for 25-30 minutes. The cookie bars should be browned on the edges with the center appearing slightly underdone. Once done, remove from the oven and allow to cool and set completely in the pan before slicing.
