Ingredient Notes

- 7 ounces marshmallow fluff – This will give your bars that iconic fluffy filling.
- 2/3 cup Nutella – Adds a rich, chocolate-hazelnut flavor that pairs perfectly with the fluff.
- 12 ounces chocolate (divided) – Use good quality chocolate for coating and drizzling.
- 7 ounces caramels – These will create that sweet, gooey layer that makes Mars Bars so addictive.
- 3 tablespoons milk – Helps to melt the caramels and create a smooth consistency.
Tools of the Trade
To make your Mars Bars, gather the following tools:
- Mixing bowl – For combining the marshmallow fluff and Nutella.
- Double boiler or microwave-safe bowl – For melting chocolate and caramels.
- Spatula – For spreading and mixing ingredients smoothly.
- 9×9-inch baking pan – To set your bars and allow them to cool.
- Parchment paper – For easy removal of the bars from the pan.
Mars Bars: How It’s Done

Step 1: Prepare the Baking Pan
Line a 9×9-inch baking pan with parchment paper, allowing some overhang for easy removal later. This step is essential to ensure your Mars Bars come out without sticking.
Step 2: Make the Marshmallow Layer
In a mixing bowl, combine the 7 ounces of marshmallow fluff and 2/3 cup of Nutella. Stir until well mixed, creating a smooth and creamy layer. Spread this mixture evenly into the prepared baking pan.
Step 3: Prepare the Caramel Layer
In a double boiler or microwave-safe bowl, combine the 7 ounces of caramels and 3 tablespoons of milk. Heat gently, stirring frequently, until the caramels are melted and smooth. Pour the caramel over the marshmallow-Nutella layer, spreading it evenly.
Step 4: Melt the Chocolate
Melt 8 ounces of chocolate using the same method as the caramel—either in a double boiler or in the microwave. Once melted, pour it over the caramel layer and spread it evenly to coat.
Step 5: Chill the Bars
Place the baking pan in the refrigerator for about 2 hours or until the bars are set. This cooling time is crucial for achieving the perfect texture.
Step 6: Cut and Serve
Once set, lift the bars out of the pan using the parchment paper overhang. Cut them into squares or rectangles as desired. You can drizzle the remaining chocolate over the top for an extra touch!
Healthier Substitutions

If you’re looking to lighten up your Mars Bars or cater to specific dietary needs, consider these substitutions:
- Use dark chocolate instead of milk chocolate for a richer flavor and added antioxidants.
- Opt for sugar-free Nutella or a nut butter alternative for a healthier filling.
- Replace caramels with homemade date caramel for a natural sweetener option.
- Use coconut cream in place of marshmallow fluff for a dairy-free alternative.
Pro Tips & Notes
- Make sure to use a good quality chocolate for melting, as it will greatly affect the taste of your Mars Bars.
- Don’t rush the chilling process; letting the bars set properly is key to achieving the right texture.
- For a fun twist, add chopped nuts or pretzels to the marshmallow layer for an added crunch.
- Store any leftovers in an airtight container at room temperature for up to a week.
Save for Later: Storage Tips
To keep your homemade Mars Bars fresh and delicious, follow these storage tips:
- Store bars in an airtight container at room temperature if you plan to eat them within a week.

- To thaw, simply leave them at room temperature for a couple of hours before enjoying.
