These Mint Oreo Cookies are perfectly fudgy, soft, and filled with the best mint buttercream! This recipe is also crazy easy to make, requiring only 5 ingredients for the cookies!
Happy National Oreo Cookie Day!! Did you know that was a thing? I already have a recipe for classic Homemade Oreo Cookies that I posted 2 years ago on my site. Funny coincidence: When I posted that recipe on March 6, 2018, I didn't even know it was National Oreo day! I found out later that day on Instagram after I had posted the recipe. Still can't believe that coincidence!! I had NO idea!
This recipe is not posted on National Oreo Day as a coincidence though. I was needing a mint recipe for St. Patrick's day this year and wanted to post another Oreo recipe. Now I have a cookie recipe perfect for Oreo day and St. Pattie's! Just crushed two occasions with one recipe or something like that!! Ah, the things food bloggers get excited about... haha!

Mint Oreo Cookies Recipe
- baking sheet(s)
- parchment paper or non-stick spray
- mixing bowl
- electric handheld mixer
- silicone spatula
- measuring cups & spoons
- piping bag with your desired tip
For the Cookies:
- ½ cup salted butter, melted
- 2 whole eggs
- 1 teaspoon vanilla extract
- 1 box chocolate fudge cake mix
- ¼ cup cocoa powder
For the Icing:
- ¼ cup salted butter, softened
- 1 ½ cups powdered sugar
- ¼ teaspoon peppermint extract
- ½ teaspoon vanilla extract
- 1 tablespoon milk
- 1 drop green liquid food colouring
- 1 drop blue liquid food colouring
To make the Cookies:
- In a large-size bowl using an electric handheld mixer on medium speed, beat together the melted butter, eggs, and vanilla until combined.
- Sift the cocoa powder and cake mix together using a sieve. Add to the wet ingredients and mix on low speed until the dry ingredients are well combined - the dough will be very soft. Cover the dough and refrigerate for 1 hour.
- Preheat the oven to 350℉. Line 2 baking sheets with parchment paper. When done chilling, roll the dough into balls, using about 1 ½ tablespoons of dough per cookie. Place on the prepared pans, 12 cookies per pan.
- Bake the cookies one pan at a time in the preheated oven for 10-12 minutes or until the tops start to crack. Let cool on the pan for 5 minutes before transferring to a wire rack to finish cooling completely before sandwiching with the frosting. Bake the remaining cookies.
To make the Frosting:
- In a medium bowl using an electric handheld mixer on medium speed, whip the softened butter until fluffy. Add the powdered sugar, peppermint extract and vanilla and beat on low speed until well combined. Add milk if the texture is too thick. Add food colouring, 1 drop at a time, until your desired colour is achieved. Pipe or spread with a knife, about 1 tablespoon of frosting per cookie, onto the cooled cookies. Enjoy!
Love and Cookies,
