Of course you don’t need an excuse to bake delicious desserts, but St. Patrick’s Day and its attendent festivities are still a great time to dust off that cookie sheet and preheat the oven. (Even if the holiday is usually eclipsed by drink and not dessert, celebrants still have to eat. Eventually.)

With that in mind, Slice has assembled a list of geeked out cookies that would be perfect for almost any St. Patrick’s Day party. Just kick up the green food coloring and voila! You’re celebrating St. Patrick’s Day with science.
