If you want to toast your pecans (you do! you do!) chop them up and throw them in a dry skillet over medium heat. Toast for 3-5 minutes, until fragrant. Don't let them burn! Remove from heat and let cool while you make the dough.
In a large bowl or stand mixer, beat the butter until it is light and fluffy.
Add both sugars and beat well, scraping sides and bottom.
Add eggs and vanilla, beat well.
Add the flour but don't mix it in. Add the salt, baking powder, and baking soda to the flour and use a small spoon to blend it with the flour a bit. Then mix in the flour, but stop before it's fully incorporated.
Add the oats, corn flakes, pecans, and coconut to the bowl. Mix in gently.
Add the peanut butter chips and chocolate chips and mix until everything is incorporated. Don't over mix, it will make your dough tough.
Chill the dough in the fridge for at least an hour, or up to 24 hours.*
Preheat oven to 350 degrees F. Line a couple baking sheets with a silpat or parchment paper.
Use a 1/4 cup measuring cup (THINK TEXAS, YA'LL)* to scoop these onto the pan. Leave at least a couple inches in between each ball of dough.
Bake at 350 for 12-14 minutes, until the cookies are golden on the edges and they are not too shiny in the middle. (A little shine is okay.)
Let cool as long as you can before stuffing your face! These are great dipped in milk.
