This recipe produces a soft chocolate chip cookie which is perfect for making cookie ice cream sandwiches. You do not have to chill this cookie dough! For best results, I recommend using mini chocolate chips and freezing the assembled sandwiches for at least 3 hours.

Prep Time: 30 minutes
Cook Time: 13 minutes
Total Time: 3 hours, 30 minutes (includes freezing)
Yield: 12 3-inch sandwiches

Ingredients

• 2 and 1/4 cups (281g) all-purpose flour (spooned & leveled)
• 1 and 1/2 teaspoons cornstarch
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 3/4 cup (12 Tablespoons; 170g) unsalted butter, softened to room temperature
• 3/4 cup (150g) packed light or dark brown sugar
• 1/2 cup (100g) granulated sugar
• 1 large egg + 1 egg yolk, at room temperature
• 2 teaspoons pure vanilla extract
• 1 and 1/4 cups (225g) mini semi-sweet chocolate chips

Sandwiching

• 3 cups (about 540g) vanilla ice cream (or your desired flavor)
• 1 cup mini chocolate chips (180g), sprinkles (150g), or finely chopped nuts (100g)

Instructions

1. Preheat oven to 350°F (177°C). Line 3 large baking sheets with parchment paper or silicone baking mats. (If you don’t have 3 baking sheets, bake the cookies in batches.)
2. Whisk the flour, cornstarch, baking soda, and salt together in a medium bowl.
3. Using a handheld or stand mixer fitted with a paddle attachment, beat the butter, brown sugar, and granulated sugar together in a large bowl on medium-high speed until combined and creamy, about 2 minutes. Add egg, egg yolk, and vanilla extract, then beat on medium-high speed until combined. Scrape down the sides and up the bottom of the bowl as needed. Beat in the dry ingredients on low speed, then beat in the chocolate chips until combined. The dough will be soft and sticky.
4. Since the dough is so sticky, I recommend using a cookie scoop and this medium size is perfect. Scoop cookie dough into balls, about 1.5 Tablespoons of dough per cookie, and arrange 3 inches apart on the baking sheets. Bake for 12–13 minutes or until lightly browned on the sides. The centers will look soft.
5. Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes. If desired, while the cookies are still warm, press extra mini chocolate chips into the tops of the cookies. This is optional and just for looks. Transfer to a wire rack to cool completely before assembling your ice cream sandwiches.
6. Assemble the sandwiches: Flip a cooled cookie over and place 1 generous ice cream scoop, about 1/4 cup or 45g, on top. Use your scoop to gently spread the ice cream to the edges. Sandwich a cookie on top, then pick up the assembled sandwich and gently press it all together in the very center to make a compact sandwich. Roll sides into mini chocolate chips, sprinkles, or nuts. If not enjoying right away (they’re messy if you don’t freeze them first), immediately wrap assembled sandwich in plastic wrap or parchment paper and place in the freezer. Repeat with remaining cookies and ice cream.
7. Freeze for at least 3 hours and up to 3 months.

Notes

1. Make Ahead Instructions: You can bake the cookies up to 3 days before assembling your ice cream sandwiches. Store covered at room temperature until ready to assemble. Assembled cookie sandwiches can freeze for up to 3 months.
2. Special Tools (affiliate links): Baking Sheets | Silicone Baking Mats or Parchment Paper | Glass Mixing Bowl | Whisk | Electric Mixer (Handheld or Stand) | Medium Cookie Scoop | Cooling Rack | Ice Cream Scoop | Plastic Wrap or Parchment Paper (for wrapping)
3. Why the cornstarch and extra egg yolk? Cornstarch helps produce a super soft cookie, which is the ideal bread for a frozen cookie sandwich. Feel free to skip the cornstarch if you don’t have any. An extra egg yolk keeps the cookies flavorful and tender. 1 egg is not enough for this dough and 2 eggs is too many, so just use the yolk of that 2nd egg.
4. I recommend mini chocolate chips: When frozen, the smaller chips aren’t as rock hard as the regular size chocolate chips. They’re simply easier (and more pleasant) to eat, plus you can enjoy more chocolate in every single bite when you use a smaller chip.
5. Ice Cream: Use your favorite flavor. There’s no need to soften your ice cream prior to assembling, though if your ice cream is particularly hard to scoop, give it a couple minutes and try again.
6. Gluten Free Options: Use these flourless almond butter chocolate chip cookies or these flourless peanut butter chocolate cookies as the “bread.” As always, make sure the ice cream you are using is labeled gluten free.
