Not exactly what you’re asking, but fyi my gluten free fiance’s favorite cookie is super simple and doesn’t require a mix, if she likes peanut butter cookies:
1 cup peanut butter
1 cup sugar (I use a mix of white and brown)
sometimes i’ll add a dash of cinnamon, vanilla, or chocolate, but totally not necessary. bake at 350 for 8-10 minutes. sprinkle sea salt if desired. super easy and gobbled up immediately.
