A festive chocolate cookie ice cream sandwich perfect for St. Patrick’s Day

There’s something so cheerful about a dessert that feels a little playful, especially when it’s dressed up for a holiday. These Minty Ice Cream Shamrocks are one of those treats that instantly make people smile.

Imagine soft chocolate cookies with just a hint of cocoa, baked until tender, then sandwiched around cool, creamy mint chocolate chip ice cream. The little shamrock shape makes them perfect for St. Patrick’s Day celebrations, but honestly, the flavor combination is good any time you’re craving something chocolatey and refreshing.

What I love most about these is how simple they are. The cookie dough comes together quickly, chills for a bit so it’s easy to roll out, and then you just cut out the shapes, bake, and fill them with ice cream. Once frozen, they turn into the cutest little homemade ice cream sandwiches.

If you’re baking with kids or planning a holiday dessert table, these are always a hit.

• 1/4 teaspoon salt

Kitchen Tools You’ll Need

• Mixing bowls
• Hand mixer or spoon
• Plastic wrap
• Rolling pin
• 3-inch shamrock cookie cutter
• Baking sheets
• Parchment paper
• Wire cooling rack

Step-by-Step Instructions

1. Make the Cookie Dough

In a small mixing bowl, cream together the softened butter and sugar until light and fluffy.

Add the egg, milk, and vanilla extract and mix until everything is nicely combined.

In another bowl, whisk together the flour, cocoa powder, baking powder, and salt.

Gradually add the dry ingredients to the butter mixture and mix just until a soft dough forms.

2. Chill the Dough

Divide the dough into two portions and flatten each one into a disc.

Wrap them in plastic wrap and refrigerate for about 1 hour, or until the dough is firm enough to roll.

This step makes rolling and cutting the cookies much easier.

3. Roll and Cut the Cookies

Preheat your oven to 350°F (175°C).

Lightly flour your work surface and roll the dough to about 1/8–1/4 inch thickness.

Using a floured 3-inch shamrock cookie cutter, cut out the cookies and place them about 2 inches apart on parchment-lined baking sheets.

If you like, gently prick the cookies with a fork.

4. Bake

Bake the cookies for 7–10 minutes, or until the cookies are set.

Let them cool on the baking sheet for about 2 minutes, then transfer them to a wire rack to cool completely.

5. Assemble the Ice Cream Sandwiches

Once the cookies are completely cooled:

Spread about 1/4 to 1/3 cup softened mint chocolate chip ice cream on the bottom of one cookie.

Top with another cookie to make a sandwich.

Repeat until all sandwiches are assembled.

6. Freeze

Wrap each sandwich in plastic wrap and place them in the freezer until firm.

For best results, freeze at least several hours or overnight.

Serving Ideas

These are wonderful served:

• At St. Patrick’s Day parties

Helpful Tips

Chill the dough well
If the dough feels sticky while rolling, pop it back in the fridge for 10 minutes.

Use softened ice cream
Let the ice cream sit at room temperature for a few minutes so it spreads easily.

Freeze the sandwiches quickly
After assembling, freeze them immediately so the ice cream keeps its shape.
