A tip for cookie mixes

I recently upgraded some cookie mixes just by:

Adding Lime zest to sugar cookie dough...mix in before adding liquid/wet ingredients. bake as usual.

Adding almond slivers and almond extract to oatmeal cookie mix. The after taste is most unexpected.

Adding dried cranberries to oatmeal or sugar cookie dough.

Mix 2 tsp cocoa into chocolate chip cookie dough.

Add chocolate chips to peanut butter cookie dough.
