• Put ½ cup chocolate chips on the bottom of the jar.
• In a small bowl, stir together the 1⅓ cups all-purpose flour, ¾ teaspoon baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Layer over the chocolate chips in the jar.
• Continue to layer with the ½ cup light brown sugar, ½ cup granulated sugar, and 1 cup old fashioned oats. Pack the layers down as you go to make sure there is enough room for everything in the jar.
• Place the lid on the jar and tie a tag onto the jar with the baking instructions.
• Homemade cookie mix can be kept in the pantry for 6-9 months. So you can make a bunch ahead of time if you would like.

To Make the Cookies

• In a medium or large bowl, stir together the melted ½ cup butter, 2 large eggs and 2 teaspoons vanilla extract.
• Pour in the contents of the jar and mix until combined.
• Chill for at least one hour but up to two days.
• Preheat the oven to 375℉. Place 1 Tablespoon scoops of dough (or a small cookie scoop) about 2 inches apart on a cookie sheet.
• Bake for about 8 minutes. Cool for a couple of minutes on the tray then move to a wire rack to cool completely.
