Preheat your oven to 350 degrees F. Toast your pecans:
If you want, take the time to toast your pecans a bit before they go in your bars. I like the extra flavor this adds, and your oven is preheating anyway, but it's not necessary. Spread 2 cups of pecans out onto a dry baking sheet
and put it into the oven at 350. Stir the pecans every 2-5 minutes. Leave the pecans in the oven for 7-10 minutes total (How long it takes will depend on if they are already chopped.) When the pecans are fragrant and toasty, take them out and set aside to cool.
