Prep and Cook Time
Prep Time: 15 minutes
Cook Time: 12 minutes
Freezing Time: 6 hours (ideal for best texture)
Yield
Makes 6 generously sized Fatboy Ice Cream Sandwiches
Difficulty Level
Medium – Perfect for adventurous home bakers craving a show-stopping dessert
Ingredients
- 2 cups all-purpose flour, sifted
- 1 teaspoon baking soda
- ½ teaspoon fine sea salt
- ½ cup unsalted butter, softened
- ¾ cup light brown sugar, packed
- ¼ cup granulated sugar
- 1 large egg
- 2 teaspoons pure vanilla extract
- 1¼ cups high-quality chocolate chips (dark or semi-sweet)
- 1 quart premium vanilla bean ice cream (softened slightly)
- Optional: sea salt flakes for sprinkling
Instructions
- Preheat your oven to 350°F (175°C) and line 2 large baking sheets with parchment paper.
- Whisk together flour, baking soda, and salt in a bowl; set aside.
- Using an electric mixer, cream the butter with both sugars on medium speed until light and fluffy-about 3-4 minutes.
- Add the egg and vanilla extract, mixing thoroughly for 1 minute to incorporate fully.
- Gradually fold the dry ingredients into the wet, blending just until combined to avoid overworking.
Tip: Overmixing can cause tough cookies instead of chewy ones. - Gently fold in the chocolate chips for bursts of melty, gooey texture.
- Portion large, palm-sized dollops (about ⅓ cup each) onto the prepared sheets, spacing them 3 inches apart.
- Bake for 10-12 minutes, until edges are golden but centers remain soft-perfect for that irresistible chew.
- Cool on sheets for 5 minutes, then transfer to wire racks to cool completely.
- Assembly: Once cookies are cool, spread a generous ½ cup of softened ice cream on the underside of one cookie, then gently press a second cookie on top to form a sandwich.
- Wrap each sandwich tightly in plastic wrap and freeze for at least 6 hours to allow ice cream firmness and flavor melding.
Tips for Success
- Cookie Texture: For an extra chewy bite, use bread flour rather of all-purpose flour.
- Flavor Variations: Swap vanilla ice cream for chocolate chip cookie dough, salted caramel, or even rich peanut butter cup flavors.
- Make-Ahead: Prepare cookie dough and freeze in balls for up to 1 month. Bake fresh anytime.
- Handling: If ice cream softens to much during assembly, briefly chill sandwiches before freezing.
- Garnish: Roll the edges of the sandwich in mini chocolate chips or rainbow sprinkles for an eye-catching finish.
Serving Suggestions
Serve chilled straight from the freezer on a vintage dessert plate or rustic wooden board. For an elevated presentation, add a drizzle of warm fudge or caramel sauce over the top and a sprinkling of flaky sea salt to balance the sweetness. Pair with a tall glass of iced coffee or a rich, dark espresso to complete the indulgent experience. Perfect for summer parties, cozy movie nights, or anytime you crave a sweet giant treat.
