Mint Chocolate Swirl Cookies
Mint Chocolate Cookies are loaded with chocolate chips and mint flavor. This combo is my all-time favorite! With St. Patrick’s Day so close by, I just wanted to share a greenish and minty dessert. We know that chocolate makes everything better, especially when its added to buttery cookies.
The cookies are made with two shortbread layers, a chocolate one and a green mint one, the flavors compliment each other beautifully. You can enjoy them in the morning with a freshly brewed cup of coffee, or for any special occasion. It is a great and festive looking dessert, that can also be made with kids, as a fun project!
Then, the layers are rolled into a cookie log to create a beautiful swirl. The chocolate and mint is always a winning combo, especially when its also looking that good!
These definitely are the perfect dessert for St. Patrick’s Day. Before I moved to the US, I didn’t even know about this holiday. But now I can’t wait for it to eat some more Beer Bread and make this amazing Guinness Beef Stew.
