To make brown sugar pecans, preheat the oven to 325˚ F.
Separate the yolk from the egg white in a large egg. Using a handheld or standing mixer, beat the egg white in a large bowl until stiff peaks form.
Fold in 1/2 cup packed dark brown sugar and 1/4 tsp. pure vanilla extract.
Depending on desired sweetness, coat pecans with the sugar mixture and spread them onto a large baking sheet.
Bake for 12 minutes, flip, and bake additional 3 minutes until golden. Let cool.
Trail Mix
For trail mix, stir together 1 cup salted peanuts, 1/2 cup raisins, 1/2 cup banana chips, 1/2 cup dark chocolate chips, and 1 heaping cup of brown sugar pecans.
