A delicious chocolate cake mix cookie recipe with amazing mint chocolate flavor, these Andes Thin Mint Cookies are just 4-5 ingredients and take less than 10 minutes to whip up.

Andes Mint Cookies with Cake Mix Recipe

These Andes Thin Mint Cookies are perfect for Christmas, St Patrick’s Day – or any time you have a mint chocolate craving.

They are that perfect combination of soft and chewy inside with a crunchy outside, and the mint chocolate flavor is unbeatable. Not only do you get that melted mint chocolate “frosting,” you also get little pops of mint chocolate in the cookies themselves thanks to the mint baking bits.

You can also stuff these thin mint cookies with thin mints or peppermint patties, like we did with our Thin Mint-Stuffed Cake Mix Cookies.

You can alter this recipe to make a variety of different cookie flavors:

• swap in Thin Reese’s Cups and peanut butter chips to make a Peanut Butter Chocolate Cookie
• swap in caramel-stuffed chocolate squares and caramel baking bits for a Chocolate Caramel Cookie
• grab different flavored peppermint patties (like raspberry or pomegranate) for even more flavor options

Can these chocolate cake mix cookies be frozen? Yes! Allow them to cool completely, then use small parchment squares to prevent them from sticking together when you store them in ziptop freezer bags or your favorite freezer containers. (This set of freezer containers is a crazy bargain.)

How to Make Andes Mint Cake Mix Cookies

Preheat oven to 350F

Line a baking tray with parchment paper or a silicone baking mat.

In a large bowl, combine the chocolate cake mix, baking chips, vegetable oil and eggs.

Beat with an electric mixer for 2 minutes, until a cohesive dough forms with no dry patches.

Use a cookie scoop to portion out 2 Tablespoon-sized pieces of dough onto the baking tray, about 3” apart.

Bake for 8-10 minutes, until cookies have puffed up and cracks have formed.

Remove the cookies from the oven and immediately place one unwrapped chocolate on each cookie.

Allow the chocolate to warm up for 3-5 minutes, then use an offset spatula to spread the melted chocolate over the cookie.

Allow the melted chocolate to set before storing or serving.

Repeat with all cookies.
