First, brown your butter. Add the butter to a skillet over low medium heat. Stir occasionally, until the butter has turned golden brown. Remove from the heat and set aside.
In a large mixing bowl, combine the brown sugar, sugar, vanilla bean powder, gluten free flour, baking soda, and sea salt. Stir to combine.
Then, add in the brown butter. Scrape any brown bits from the bottom of the skillet into the mixing bowl.
Next, add in the eggs. Stir to combine.
Fold in the chocolate chips. Use a cookie scoop to scoop out balls of dough onto a parchment lined baking sheet.
Dot the tops of each dough ball with white chocolate chunks if desired.
Place the pan in the fridge for 30 minutes. Then, preheat your oven to 350 degrees Fahrenheit.
Bake for 10 to 12 minutes, or until the edges are set and the middles are still slightly gooey.
Finally, remove from the oven. Allow these inside out cookies to cool for 15 minutes on the pan before removing to a cooling rack.
