Deep chocolate cookies and mint chocolate chip ice cream make a sandwich that lands cold, creamy, and just a little bit nostalgic. The cookies stay soft enough to bite through straight from the freezer, while the ice cream firms up into a clean middle that doesn’t squish out the sides. With the Andes mint pieces pressed around the edges, each bite gives you a sharp peppermint finish that makes the whole treat taste brighter and colder.
The trick here is keeping the cookies thick enough to stay tender after freezing, but not so puffy that they crack when you press them together. A modest amount of peppermint extract in the dough keeps the chocolate base cool and fragrant without turning the cookies into toothpaste territory, and the vanilla rounds it out so the mint tastes clean instead of harsh. Let the cookies cool all the way before assembling, or the ice cream will melt into the seams and make the sandwiches sloppy.
Below you’ll find the timing that matters, the one substitution that works if you need a dairy-free version, and the small freezing step that gives these sandwiches their neat edges.
The cookies stayed soft after freezing and the mint chips on the edge made them taste like the ice cream shop version my kids always ask for. I let them freeze overnight and they sliced through cleanly instead of falling apart.

The Cookies Need to Stay Soft After Freezing
Ice cream sandwiches fail when the cookies bake up dry or crisp. Once they hit the freezer, that kind of cookie turns hard and brittle, and the whole sandwich cracks instead of biting cleanly. The goal here is a deep chocolate cookie that finishes set at the edges but still has enough tenderness in the center to stay pleasantly chewy after a full freeze.
The cocoa powder does more than add color. It gives the cookie a sturdy structure that holds up against the ice cream without tasting cakey. A short bake is part of the plan. Pull them when the tops look matte and the edges are just set, because the cookies keep firming as they cool on the pan.
What the Peppermint Extract and Andes Mints Are Really Doing
Peppermint extract gives the cookie dough its cool finish. Use peppermint, not mint extract if you have the choice, because peppermint tastes clean and bright instead of grassy. A little goes a long way, and the measured amount here is enough to echo the ice cream without overpowering the chocolate.
Mint chocolate chip ice cream does the heavy lifting in the center, so pick one with a flavor you already like eating from the carton. If your ice cream is hard as a rock, let it soften just until scoopable, not slushy. Andes mint pieces on the edge add crunch and a second layer of chocolate mint flavor, but crushed peppermint candies can stand in if that’s what you have. They’ll be a little sharper and harder, which is fine if you like a stronger mint bite.
- Unsweetened cocoa powder — This creates the dark cookie base and helps the sandwiches taste balanced instead of overly sweet. Dutch-process cocoa works too and gives a smoother, darker flavor.
- Butter — Softened butter creams with the sugar to trap air, which keeps the cookies from turning dense. If the butter is too warm, the dough spreads too much and the cookies get thin.
- Peppermint extract — This is where the cool mint note starts. Add the exact amount called for; too much and the cookies taste sharp and medicinal.
- Mint chocolate chip ice cream — The center needs to be soft enough to spread but firm enough to hold its shape. Any good-quality mint chip ice cream works, and homemade works too if it freezes scoopable.
- Andes mint pieces — These make the edges look finished and add a little crunch. Press them on while the ice cream is still tacky so they actually stick.
Building the Sandwiches Before the Ice Cream Melts
Mixing the Dark Dough
Start by whisking the dry ingredients so the cocoa and baking soda disperse evenly. Then beat the butter and sugar until the mixture looks fluffy and a little paler; that step gives the cookies some lift without making them cake-like. Add the eggs and extracts only after the butter base is smooth, or the dough can look curdled before it comes together. Once the flour goes in, stir just until you no longer see dry streaks.
Baking for a Soft Center
Scoop the dough into large rounds and press them flat so they bake into sandwich-friendly disks instead of domes. Bake until the edges are set and the centers no longer look wet, then leave them on the pan long enough to finish cooking from residual heat. If you try to move them too early, they’ll tear; if you overbake them, they’ll harden in the freezer. Cool them completely before you even think about filling them.
Assembling and Freezing Clean Edges
Pair up cookies that match in size. Spoon softened ice cream onto the flat side of one cookie, then press the second cookie on top gently until the filling reaches the edges. Roll the exposed ice cream edge in crushed Andes mint pieces right away, before the ice cream firms up. Freeze the sandwiches on a tray for at least an hour so they slice cleanly and hold their shape when served.
How to Tweak These for Different Freezers, Cravings, and Diets
Dairy-Free Mint Chocolate Chip Sandwiches
Use a dairy-free butter and a mint chocolate chip frozen dessert that scoops and freezes like ice cream. The cookies themselves are already dairy-free once you swap the butter, and the result stays close in texture, though the filling may soften faster at room temperature.
Extra-Intense Chocolate Mint Version
Swap a small portion of the flour for extra cocoa only if you want a darker, more assertive chocolate cookie. Keep the mint extract measured exactly, because the stronger chocolate will make too much peppermint stand out even more.
No Andes Mints on Hand
Crushed peppermint candies, mini chocolate chips, or even chopped chocolate wafers can go around the edges instead. You’ll lose the soft, creamy chocolate-mint bite that Andes pieces give, but the sandwiches will still look finished and taste balanced.
Storage and Reheating
- Refrigerator: These don’t belong in the fridge for long. The ice cream melts and the cookies turn soggy within hours.
- Freezer: Store tightly wrapped or in an airtight container for up to 2 weeks. Separate layers with parchment so the mint pieces don’t stick to the lid.
- Reheating: No reheating needed. Let a sandwich sit at room temperature for 3 to 5 minutes before serving so the cookie softens slightly and the ice cream isn’t rock hard.

Ingredients
Equipment
Method
- Preheat the oven to 350F and line a sheet pan. Whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt until evenly combined.
- In a bowl, beat the softened unsalted butter and granulated sugar until fluffy. Add the eggs, peppermint extract, and vanilla extract and mix until smooth.
- Add the flour-cocoa mixture to the wet ingredients and stir until a dark dough forms. Scrape the bowl so no dry streaks remain.
- Scoop the dough into large rounds, press flat, and space them on the sheet pan. Bake for 10-12 minutes, until set at the edges and fragrant.
- Transfer cookies to a rack and cool completely. This ensures they won’t melt the ice cream during sandwiching.
- Place mint chocolate chip ice cream between two cooled cookies. Sandwich gently so the cookies meet around the ice cream.
- Roll the exposed ice cream edges in crushed Andes mint pieces. Press lightly so the mint coating sticks.
- Freeze the assembled sandwiches for at least 1 hour before serving. Keep them frozen until ready to slice and eat.
