Start by browning your butter. Add the butter to your pan, I like to use stainless steel. Heat over medium heat. You will want to keep an eye on this as it can go from toasty to burned pretty quick.
Stir gently and constantly. Once it melts all the way, it will start to foam after a few minutes. Continue to stir. It will change colors and become a deep golden brown. You will also smell a nutty smell from the butter. Mine still has the foam on top.
As soon as it reaches this point, remove it from the heat quickly and pour it into a bowl. Let it cool for about 10 minutes, then start with the rest.
While it is cooling, mix your all-purpose flour, wheat flour, salt, cornstarch, and baking soda in a small bowl and set it aside.
When the butter is ready, add in the sugars and mix well. This will also help to cool the butter. Add the eggs and vanilla and mix well.
Next, add in the flour mixture and only mix until it is all combined. Last up is the pecan pieces. Mix them to combine as well.
Cover the top of the dough with saran wrap, I just leave it in the bowl. Move it to the fridge and chill for at least 4 hours. I prefer chilling at least overnight.
If you have let it chill overnight, you will need to bring it out at room temperature for at least an hour to soften it slightly.
Preheat the oven to 375 degrees. Scoop your cookies onto a parchment-lined baking sheet. These cookies will spread a bit, so give them a few inches to do this.
Place in the preheated oven. Bake until the edges are a golden brown, mine took right around 10 minutes, but plan on 10-13 minutes.
Remove from the oven and allow them to cool a few minutes on the baking sheet.
Then move them to a cooling rack. These cookies are delicious when they are hot, but also really good when they are cooled! Enjoy with a nice glass of cold milk!
They will hold well in an airtight container at room temp for at least 3 days.
Not, sit back and enjoy. You deserve it.
