Easy Caramelized Walnuts Recipe (made in minutes!)

0 Prepare a cookie sheet lined with parchment paper and set it aside. 
1 In a medium non-stick skillet over medium heat, add the walnuts, butter, and sugar. Stir constantly using a wooden spoon, allowing the butter and sugar to melt for about 5 minutes. Once the sugar dissolves, the walnuts are fully coated, and with a golden brown color, turn off the heat. 
2 Spread the walnuts onto the sheet of parchment paper in a single layer to prevent clumping. Let the caramelized walnuts cool for approximately 5 minutes, then store any leftovers in an airtight container.
