What Is Costco Mint Chocolate Sundae?

The Costco Mint Chocolate Sundae is a seasonal dessert offered at Costco’s food courts. This treat features mint-flavored soft-serve ice cream swirled with rich chocolate sauce, topped with chocolate chunks and cookie crumbles.

Ingredients:

For The Mint Ice Cream:

• 2 cups heavy cream
• 1 cup whole milk
• 3/4 cup granulated sugar
• 1 teaspoon pure peppermint extract (adjust to taste)
• A few drops of green food coloring (optional, for that iconic mint color)

For The Chocolate Fudge Sauce:

• 1/2 cup heavy cream
• 3/4 cup semi-sweet or dark chocolate chips
• 2 tablespoons unsalted butter
• 1 tablespoon corn syrup or honey (for shine)

For The Toppings:

• Chocolate cookie crumbles (Oreo cookies or chocolate wafers, crushed)
• Mini chocolate chunks or chips

Instructions:

Prepare The Mint Ice Cream Base:

1. In a medium bowl, whisk together the heavy cream, whole milk, sugar, and peppermint extract until the sugar is completely dissolved.
2. If you want that signature green-blue hue, add a few drops of green food coloring and mix well.
3. Chill the mixture in the refrigerator for at least 1 hour to ensure it’s cold—this helps the ice cream churn better.

Churn The Ice Cream:

1. Pour the chilled mixture into your ice cream maker and churn according to the manufacturer’s instructions (typically 20-25 minutes) until it reaches a soft-serve consistency.
2. Transfer the ice cream to an airtight container and freeze for at least 2 hours to firm up.

Make The Chocolate Fudge Sauce:

1. Heat the heavy cream in a small saucepan over medium heat until it begins to simmer.
2. Remove from heat and add chocolate chips, butter, and corn syrup.
3. Stir gently until the chocolate and butter have completely melted, creating a smooth, glossy fudge sauce.
4. Let it cool slightly to thicken but remain pourable.

Assemble The Sundae:

1. Scoop the mint ice cream into serving bowls or cups.
2. Drizzle the chocolate fudge sauce generously over the top.
3. Sprinkle with chocolate cookie crumbles and mini chocolate chunks for extra texture and chocolate flavor.

Tips For Costco Mint Chocolate Sundae:

• Peppermint Extract: Start with 1 teaspoon, then taste your mixture before churning. Adjust as desired, since peppermint extract can be strong.
• Texture: For a creamier texture, chill the ice cream mixture thoroughly before churning.
• Fudge Sauce: The addition of corn syrup or honey helps keep the fudge sauce smooth and shiny.
• Toppings: Experiment with different chocolate cookie types or add nuts for some crunch.
• Serving: Allow the fudge sauce to warm slightly before drizzling so it flows smoothly over the ice cream.

What To Serve Costco Mint Chocolate Sundae With

• Warm Brownies or Chocolate Cake: The contrast between the cold, creamy mint ice cream and warm, fudgy brownies or chocolate cake creates a delightful texture and temperature play. The rich chocolate layers in the cake perfectly complement the cool mint flavor of the Costco Mint Chocolate Sundae. Serving a warm brownie on the side, or even crumbling it over the sundae makes each bite indulgent and satisfying.
• Fresh Berries: Bright, tart berries such as raspberries, strawberries, or blueberries add a fresh, juicy burst that balances the sweetness of the ice cream and chocolate. Their natural acidity refreshes the palate and adds vibrant color to your dessert plate, making it visually appealing.
• Whipped Cream: A dollop of lightly sweetened whipped cream adds lightness and an airy texture. It also enhances the overall creaminess of the Costco Mint Chocolate Sundae while complementing the rich chocolate fudge sauce. For an extra touch, consider topping the whipped cream with a few dark chocolate shavings or crushed peppermint candies.
• Chocolate or Mint Cookies: Crunchy chocolate or mint-flavored cookies provide an inviting crunch that contrasts with the softness of the ice cream. You might serve whole cookies on the side or crumble them over the sundae as a topping. This adds layers of texture and intensifies the mint-chocolate theme.
• Espresso or Coffee: A small cup of espresso or strong coffee pairs wonderfully with the mint chocolate sundae. The bold bitterness of coffee cuts through the richness and sweetness, creating a sophisticated balance of flavors. For an extra treat, consider an affogato-style serving where hot espresso is poured directly over the ice cream.
• Mint-Infused Water or Sparkling Lemonade: To keep the experience refreshing, serve the sundae with chilled mint-infused water or sparkling lemonade. These light beverages cleanse the palate and complement the mint flavor without overpowering the dessert.
