To make these brownies, start by preheating your oven to 350 F.
Next, prepare the brownie batter by adding the brownie mix to a large bowl and preparing it according to the package instructions.
Then, line an 8x8 or 9x11 baking dish with parchment paper and transfer the brownie mix to the dish, using a spatula to spread the batter out evenly.
Cook the brownies for half the amount of time stated on the box.
While the brownies are baking, prepare the pecan layer by mixing together the pecans, coconut sugar, maple syrup, butter, vanilla extract, and flaky sea salt together in a small bowl. Set it aside while the brownies finish baking.
Once the time is up on the brownies, remove them from the oven and add the pecan layer on top.
Then, place the brownies back in the oven for 25-27 minutes, or until a toothpick comes out clean.
Allow the brownies to cool completely before slicing them into 12 squares. Once they're done, serve them and enjoy! Store any leftovers in an airtight container on the kitchen counter for up to 3 days, or in the fridge for up to one week.
