Preheat oven to 375 degrees.
In a small saucepan over low heat, add butter. Allow butter to melt and then butter will begin to lightly bubble. Continue to stir frequently until butter turns into a nice golden brown. It will give off a sweet nutty flavor. Then, remove from heat to let cool.
Once butter has mostly cooled, add to the bowl of your stand mixer along with the brown and white sugars. Beat over medium speed until smooth. Add vanilla extract and egg to the mixture and beat until just combined.
In a separate bowl, whisk together flour, baking soda and salt. Add to the wet mixture and beat over medium speed until just combined. Remove bowl from mixer to fold in the white chocolate chips.
Roll cookie dough into balls, about 2 tablespoons of dough, onto your parchment paper or silicone sheet lined baking sheet.
Bake cookies for 9-10 minutes.
When done, the cookies will be lightly golden and a toothpick will run through the cookie and come out clean. Transfer to a cooling rack to let cool. Enjoy!
