Recipe Card
- Prep Time: 30 minutes
- Cook Time: 0 minutes
- Total Time: 30 minutes
- Servings: 12 bars
Ingredients:
- 2 cups mini marshmallows
- 1 cup semi-sweet chocolate chips
- 1/4 cup unsalted butter
- 1/4 cup light corn syrup
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon salt
Detailed Instructions:
Combine the mini marshmallows, chocolate chips, butter, and corn syrup in a microwave-safe bowl. Heat in 30-second intervals, stirring between each burst, until the mixture is fully melted and smooth. Stir in the vanilla extract and salt until everything is well incorporated.
Lightly grease a 9×9-inch baking dish and pour in the glossy chocolate-marshmallow mixture, spreading it evenly to the edges. Let the pan sit at room temperature for about two hours, or chill in the refrigerator for about one hour if you prefer a quicker set. Once firm, slice into 12 bars and enjoy.
Recipe Notes:
- For variation, sprinkle crushed peanuts, toasted coconut, or colorful sprinkles over the top before the bars set.
- Store finished bars in an airtight container at room temperature for up to one week, or refrigerate to extend freshness.

FAQs Section
Can I use dark chocolate instead of semi-sweet chocolate chips?
Yes. Dark chocolate will give the bars a deeper, more intense chocolate flavor.
Can I make these bars in advance?
Yes. They keep well in an airtight container for up to a week, making them a convenient make-ahead treat.
Can I use honey instead of corn syrup?
You can substitute honey, though it will slightly change the texture and flavor. Light corn syrup helps keep the filling smooth and pliable.
Serving Suggestions
These bars are delicious on their own, but here are a few serving ideas to elevate them:
- Pair a bar with a scoop of vanilla ice cream for an indulgent dessert.
- Dust with powdered sugar for a prettier presentation.
- Serve with coffee or a glass of cold milk to balance the sweetness.
