Crispy M&M Cookies

Hello everyone! Crispy M&M Cookies for your today! A thick NYC style cookie packed with Crispy M&Ms and chunks of chocolate chips. A delicious combo with a crisp outside and gooey center!. These are a NYC style cookie perfect for any cookie lovers out there!

I chilled my cookie balls in the freezer for 1 hour beforehand to keep them from spreading too much and keep some height on them. What’s handy about these cookies is that you can keep them in your freezer in an airtight container. Then bake them as you want them. These cookies are delicious warm. The following day you can warm them up for about 20-30 seconds in the microwave to re-melt the chocolate.

If you don’t want to make these Crispy M&M Cookies as big as they are you could make them half the size instead. Just make sure to reduce your cooking time according to how many you would like to make. If you don’t want to cook all your cookies at once you can leave some dough balls in the freezer in an airtight container for a few months!

If you have any questions Dm me on Instagram. Happy Baking! <3 Keep an eye out on my Instagram for a Reel of me making these Crispy M&M Cookies cookies!
