home made gluten free dry mixes

cookies

My parents have requested that I make them a variety of gluten free cookie mixes. I started with a layered oatmeal raisin mix that fit well into a large jar, but only when the recipe was halved. My next attempt was chocolate chip, and the above is what happened.. I had to use two jars.

So, I seem to be having trouble getting any of my mixes to fit into my mason jars. My frustration is that I want to use my own recipes, not those designed to fit into a jar.

I think perhaps I should just invest in some bigger jars.muffins

Until then… Here is my oat bran muffin mix not fitting in a jar.

Do you make these jar mixes? How do you get them to fit? Help!
