Mastering 3-Layer Caramel and Chocolate Marshmallow Bars: How-To

Step 1: Prepare the Baking Dish
Start by preheating your oven to 350°F (175°C). Line the bottom of a 9×13 inch baking dish with parchment paper, allowing some overhang for easy removal later.
Step 2: Make the Graham Cracker Base
In a medium bowl, crush the Keebler Graham Crackers into fine crumbs. You can use a food processor or simply place them in a zip-top bag and crush them with a rolling pin. Once crushed, add a tablespoon of melted butter to the crumbs and mix until the texture resembles wet sand. Press this mixture firmly into the bottom of the prepared baking dish to form an even layer.
Step 3: Create the Caramel Layer
In a microwave-safe bowl, combine the caramel pieces with a splash of water. Heat in the microwave in 30-second intervals, stirring in between until the caramel is completely melted and smooth. Pour the melted caramel over the graham cracker crust and spread it out evenly. Sprinkle the mini marshmallows on top of the caramel layer.
Step 4: Melt the Chocolate
In another microwave-safe bowl, melt the Dove Dark Chocolate using the same method as before—heat in 30-second intervals, stirring in between until smooth. Once melted, pour the chocolate over the marshmallows and spread it evenly using a rubber spatula.
Step 5: Chill and Set
Place the baking dish in the refrigerator for at least 2 hours to allow the layers to set properly. Once set, use the parchment paper to lift the bars out of the dish.
Step 6: Cut and Serve
Using a sharp knife, cut the bars into squares or rectangles. Serve chilled or at room temperature and enjoy your delicious 3-Layer Caramel and Chocolate Marshmallow Bars!
Smart Substitutions

- For a gluten-free option, use gluten-free graham crackers.

If You’re Curious

Keep-It-Fresh Plan
To ensure your 3-Layer Caramel and Chocolate Marshmallow Bars stay fresh, store them in an airtight container in the refrigerator. They can last up to a week, but trust us, they won’t last that long! If you want to keep them for longer, consider freezing them. Just wrap the bars tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to three months.
Troubleshooting Q&A
What if my chocolate doesn’t melt smoothly?
If your chocolate isn’t melting smoothly, it’s likely been overheated. Try adding a teaspoon of vegetable oil or coconut oil to the chocolate and remelt it gently in the microwave, stirring frequently.
How do I fix a sticky caramel layer?
If your caramel layer is too sticky, it may not have been cooked long enough. Make sure to melt the caramel pieces thoroughly and mix them well with any added liquid to achieve the right consistency.
Can I make these bars ahead of time?
Absolutely! These bars can be made up to a day in advance. Just make sure to store them in the refrigerator until you’re ready to serve.
Why is my graham cracker crust crumbly?
If your graham cracker crust is crumbly, it may not have enough melted butter. Ensure that you mix the crumbs with enough butter to help the crust hold together when pressed into the pan.
