Begin by cleaning and drying a 32 oz jar. This is often a size of store-bought pasta sauce, so that's what I used here. Begin layering in ingredients in the order they are listed; begin with flour, rolled oats, baking soda, sea salt, brown sugar, and granulated sugar. Use a spoon to pack each layer down as you go; this will result in the most even layers. Top jar off with chocolate candies of choice and tie with a ribbon. The jar of mix is really only half of the gift - it's important to supply a recipe so your recipient can actually make these on their own. To download a printable recipe card, click here. 

To make the cookies, preheat the oven to 375 degrees F. and line two baking sheets with parchment or silicone mats. Blend 1 flax egg with ¾ cup butter and 1 teaspoon vanilla extract in a stand mixer or with a hand mixer. Pour in cookie mix and beat to combine, until incorporated. Scoop out 1 TBS-sized cookies and space them evenly across the baking sheets. You will have around 25 cookies in total. 

Bake cookies for 10-12 minutes, until browned on the edges and firm in the middle. Let cool on the baking sheets, where they will cook a bit more. Store cookies in a sealed container at room temperature for 5-7 days.
