In a separate bowl, whisk together the oil (or butter), vanilla extract, agave and 5 tablespoons coffee.
6 Add the wet ingredients to the dry ingredients, stirring until smooth. If the dough is too stiff, add more coffee as needed to soften. The finished dough should be thick.
7 Stir in potato chips.
8 Roll dough into walnut-sized balls and place two inches apart onto a sheet pan lined with parchment. Bake on the bottom rack for 15-17 minutes.
9 Remove from oven to cool for five minutes then transfer cookies to a cooling rack.
10 Repeat until all dough is used.
