I can't wait to tell you about my go-to Mint Chocolate Sandwich Treats! Whenever I bake these chocolate cookies with minty filling, they vanish in minutes. There's something magical about the mix of chocolatey cookies, creamy mint filling, and smooth chocolate topping. They're a hit during March holidays, but honestly, we love them throughout every season!

What Makes These Treats Irresistible

There's something special about how the chocolate and mint work together in these cookies. I love seeing everyone's surprise when they spot that pretty green filling and shiny chocolate layer on top. And guess what? They start with a box mix, so you can throw them together in no time!

Grab These Ingredients

  • Box of Chocolate Cake Mix: The secret to quick, perfect cookies every time.
  • Vegetable or Canola Oil: This gives them that soft, chewy texture.
  • Eggs: They bind everything nicely.
  • Unsalted Butter: The base for our fluffy mint layer.
  • Powdered Sugar: Creates that silky frosting texture.
  • Mint Extract: Just a bit gives that cooling flavor kick.
  • Green Food Coloring: For that eye-catching mint look.
  • Heavy Whipping Cream: Makes everything rich and velvety.
  • Semi-Sweet Chocolate Chips: The star of our shiny topping.
  • Salt: A tiny amount brings all flavors to life.

Cooking Steps

Creating Your Cookie Base
Combine your box mix with oil and eggs until you get a workable dough. Drop spoonfuls onto your prepared cookie sheets, leaving space between them.
Into The Oven
Bake at 350°F for around 10-12 minutes, then let them cool totally before moving on.
Whipping Up The Mint Layer
Whip your butter until fluffy, then add powdered sugar, cream, mint extract, salt and green coloring until you get that perfect shade.
Adding The Filling
Gently spread the mint mixture onto each cooled cookie.
Creating The Chocolate Layer
Warm your cream and pour over chocolate chips, stirring until completely melted. Let it thicken slightly before using.
Finishing Touches
Drizzle a spoonful of chocolate over each mint-covered cookie and wait for it to set up.

Creative Twists

You can top them with crushed Andes candies for extra texture. Don't have mint extract? Peppermint flavor works just as well. Need a gluten-free version? Just grab a gluten-free chocolate cake mix instead.

Storage Secrets

Keep these treats in a sealed container on your counter for a day or two, or in your fridge for about four days. Want to plan ahead? They freeze really well for up to three months if you place parchment paper between layers.

Smart Baking Tricks

I always grab my ice cream scoop when making these so they turn out the same size and bake evenly. Don't rush the cooling step or your frosting will run everywhere. Different brands of cake mix might need tweaking with the oil amount, so trust your gut on the dough consistency.

Recipe FAQs

→ Can I use any brand of cake mix?

Yep, any kind will work. Just aim for around 15.25 ounces in weight.

→ What's the meaning of Grasshopper?

It comes from the cocktail that blends chocolate and mint flavors, just like these cookies.

→ Can I skip the green coloring?

Sure! It's just for the look. The flavor will stay the same without it.

→ When is the ganache ready to use?

Wait until it's slightly thick but still spreads easily, usually about 10-15 minutes.

→ Can I swap out the mint extract?

Absolutely. Try vanilla or almond for a new twist, or tweak the mint to your liking.
