Single serving chocolate chip cookies...in a jar! A Pazookie. I recently made them for my son's birthday. [They hold a candle perfectly! Great birthday dessert.] Simply make your favorite chocolate chip cookie recipe, fill 4oz mason jars 1/2 full with dough, and bake them at 375 degrees for about 15 minutes. You can let them cool completely or serve while warm with a scoop of really good vanilla ice cream on top. The outside is crisp but the inside is gooey goodness. Low labor, huge impact!
