Add the flour to the mason jar. Then add the baking soda and baking powder on top.
Pack the ingredients in tight using either a tamper tart tool or a packing utensil.
Clean the inside of the jar so there is no excess flour. You want to see a straight line of flour.
Add the sugar in using a funnel. Pack this in as well.
Add the white chocolate chips in on top and gently pack them in. Do not press too hard or they will start to break.
Finally add the macadamia nuts on top.
Add the lid, place the fabric on top and secure with string. Add the recipe card.
To Bake the Cookies:
Preheat the oven to 375°F. Line a baking sheet with parchment paper.
In a large bowl, cream together the egg, butter and vanilla.
Fold the ingredients of the mason jar into the wet ingredients until combined.
Use a cookie scoop and dollop the cookie dough onto the prepared baking sheet with about an inch in between each cookie.
Bake for 8 - 10 minutes or until the cookies are golden brown. Remove the tray from the oven.
All the cookies to rest on the baking tray for 10 - 15 minutes before removing to a cookie rack to finish cooling.
Notes
Layer the dry ingredients in the jar in a specific order.
Use a small spoon or the back of a measuring cup to pack down each layer to ensure that the ingredients fit tightly in the jar. This will prevent air pockets and keep the ingredients fresh.
This recipe will fill a standard 32-ounce mason jar.
