Aggie Blue Mint Crumbl Copycat

Is there any better combination of flavors than chocolate and mint? I love it in all its forms! Don’t even ask me how many boxes of Thin Mints I currently have in my freezer!

And while I haven’t mastered the perfect Thin Mint recipe (yet), this mint chocolate Crumbl Copycat is absolutely perfect!

Aggie Blue Mint cookies taste just like the best mint chocolate chip ice cream but in the perfect cookie form! And you guys, they couldn’t be easier to make!

Blue Mint cookies were just featured last month at Crumbl, but with their rotating menu, who knows when we will see these bad boys again. So now you can make them in your very own kitchen whenever you want…and believe me, you will want to make them A LOT!

Ingredients In Aggie Blue Mint Cookies

For the cookies-

  • Softened Butter- I always use salted because it is what I have on hand, but you can use whatever you have. Just make sure it’s softened so that it creams well with the sugar. If you use unsalted, you’ll want to add a pinch of salt to the dough.
  • Granulated Sugar- This recipe just uses white sugar because it is a sugar cookie base.
  • Eggs
  • Vanilla
  • Baking Powder
  • Flour- Just plain old all purpose flour works best.
  • Canola Oil- This is the secret. A little bit of canola oil in the dough will give the cookies a crisp buttery edge.
  • Oreos- Break Oreos into medium size pieces. This is a fun way to get the kids involved!
  • White Chocolate Chips- Feel free to use your favorite brand. I always use Tollhouse.

For the frosting-

  • Softened Butter- Again, it could be salted or unsalted, but make sure it is softened so that it can cream well with the powdered sugar. If you use unsalted, just add a pinch of salt to the finished frosting.
  • Powdered Sugar
  • Milk- There is no exact measurement here. Just start with about a tablespoon and go up from there until you reach the desired consistency.
  • Finely Chopped Oreos- In the cookies I like to break the Oreos up but still keep them in big chunks. For the frosting, the Oreos should be chopped super fine.
  • Mint Extract- You will want to use MINT extract, not PEPPERMINT. I use McCormick extract, but you can use whatever brand you have or can find.
  • Blue Food Coloring- Obviously this isn’t a mandatory ingredient, and it won’t change the flavor at all, but if your want the cookies to look like Crumbl.

How To Make Aggie Blue Mint Cookies

First, preheat the oven to 350 degrees.

While the oven is preheating begin the cookie dough by creaming together the butter and sugar until light and fluffy. Scrape the sides of the bowl and add the eggs, vanilla extract and oil and beat again until it is mixed well.  Scrape the sides again and add the flour and baking powder. Mix again until thoroughly combined. Add in the chopped Oreos and chocolate chips and mix until well incorporated.

Scoop out 1/3 cup of dough and roll it into a ball. Flatten the dough just slightly with your hands. The dough will continue to spread and flatten as it bakes. Bake at 350 degrees for 13-16 minutes. Be careful not to overbake the cookies, you will know they are done because the center of the cookie will puff up and they will no longer look wet on the top. Remove the cookies from the oven and allow them to cool completely on the cookie sheet.

While the cookies cool, make your frosting by creaming the butter until super smooth. Slowly add the powdered sugar, mint extract and cream to the frosting until it is smooth and creamy. Slowly add milk until your frosting has reached the desired consistency.

Add the chopped Oreos to the frosting and mix slightly. Now add the Blue food coloring until it reaches the desired color. I usually use about 5 drops.

Frost the cookies and chill in the fridge for at least a half hour before serving. These cookies are served chilled, so store them in the fridge!

What is Aggie Blue Mint?

Crumbl was started in Logan Utah. Logan is also home to the Utah State Aggies. (Aggies is short for Agricultural) With a mascot like that, you better believe that Utah State has its own dairy. And the best part of that dairy? The ICE CREAM! The most beloved and iconic Utah State ice cream flavor is Aggie Blue Mint!

Imagine the best mint chocolate chip ice cream you’ve ever had and then substitute the chocolate chips for little pieces of Oreo and you will have Aggie Blue Mint ice cream. (Yes it is as delicious as it sounds!) And this cookie tastes just like the ice cream…only in cookie form!

How to Store Leftover Cookies

Cookies should be stored in an air tight container in the fridge for up to 7 days or frozen with or without frosting for longer storage.

Can I Freeze my Cookies?

Yes! As mentioned above, these freeze great! You can freeze the dough, or you can freeze the baked cookies with or without frosting. If you are wanting to freeze the dough, portion out and shape the dough like you would if you were to bake the cookies.

Instead of baking the cookies, put them on the pan and then freeze them for about an hour. Once they have been frozen for about an hour, you can then put them all into a zip top bag and freeze for up to 3 months. Flash freezing on the pan will make it so they don’t stick to each other, meaning you’ll be able to take out and bake one cookie at a time, if thats what you want to do.

To freeze the baked cookies, I generally frost first and then freeze. The frosting freezes great! I will frost the cookies and place them in the fridge for a good hour or so, until the frosting hardens. Then I will put 4 to a gallon sized zip top bag and freeze for up to 3 months.

When you are ready to thaw your frozen cookies, you can just let them sit at room temperature for 30 minutes to an hour. If baking the cookies from frozen dough, let the cookie dough sit at room temperature for 30 minutes prior to baking.

Copycat Aggie Blue Mint Cookie

Crumbl's Aggie Blue Mint cookies are minty chocolate Oreo perfection! With my perfected Crumbl cookie copycat recipes it is easier than ever to make Crumbl cookies in your very own kitchen!
Prep Time: 30 minutes
Cook Time: 15 minutes
Chill Time: 30 minutes
Servings: 24 servings (1/2 cookie per serving)


Cookies and Cream Cookie Base

  • 1 1/2 cups (333 g) salted butter, softened
  • 1 1/2 cups (345 g) granulated sugar
  • 3 eggs
  • 3 teaspoons vanilla extract
  • 4 1/2 cups (684 g) all-purpose flour
  • 3 teaspoons baking powder
  • 1/4 cup (60 mL) canola oil
  • 20 oreos, broken into medium sized pieces
  • 1 cup (200 g) white chocolate chips

Aggie Blue Mint Frosting

  • 1/2 cup (111 g) salted butter, softened
  • 3 cups (321 g) powdered sugar
  • 1 1/2-3 tablespoons milk, for consistency
  • 6 oreos, finely chopped
  • 1/4 teaspoon mint extract
  • blue food coloring


  • Preheat oven to 350°F (180°C).
  • Cream together the butter and granulated sugar until light and fluffy. About 1 minute.
  • Add in the eggs and vanilla. Mix until thoroughly combined.
  • Next, add the flour and baking powder. Mix until the dough forms.
  • Add in the canola oil and mix until the oil is fully incorporated into the dough.
  • Add the Oreo pieces and white chocolate chips, mixing until they are evenly distributed in the cookie dough.
  • Scoop a generous 1/3 cup of dough for each cookie. Roll each cookie into a ball and then flatten slightly. The cookie will spread slightly while baking.
  • Repeat with remaining dough.
  • Bake at 350°F (180°C) for 13-16 minutes. The cookies should spread and the centers of the cookie should look dry and baked, no longer glossy & wet like unbaked cookie dough.
  • Allow the cookies to cool completely on the pan.
  • Once the cookies have cooled, make the Aggie blue mint frosting by first creaming the butter until it is nice and smooth.
  • Next add in the powdered sugar one cup at a time, mixing until it combines with the butter. You will need to add in a little bit of milk (think a few tsp at a time) while mixing in the powdered sugar to keep it a good frosting consistency.
  • Once all of the powdered sugar has been incorporated, mix in the finely chopped oreos and mint extract. Mix until well combined.
  • Lastly, stir a few drops of blue food coloring at a time into the frosting by hand until you've reached your desired color. (I usually use about 5 drops of food coloring.)
  • Frost each cooled cookie by spreading the frosting onto the top of each cookie.
  • Chill the cookies in the fridge for at least 30 minutes before serving. Serve chilled.

    My kids and friends love these cookies. They are super easy to make and alwasy turn out perfect. I have one question, my icing always turns a gray color because of the Oreos. How did you get your frosting to be such a pretty blue?
