Banana Split S'mores Dip

This warm, gooey Banana Split S'mores Dip combines caramelized bananas, melted chocolate, and toasted marshmallows for the ultimate easy party dessert.

Why This Recipe Works:

• Caramelizing the bananas reduces moisture, preventing a watery dip while intensifying the fruit's natural sweetness.
• Using a heavy cast-iron skillet provides excellent thermal mass, keeping the dip warm and scoopable long after it leaves the oven.
• A tiny pinch of kosher salt cuts through the intense sweetness of the marshmallows, balancing the overall flavor profile.

My first attempt at a backyard movie night ended in a minor disaster when my cheap wire camp fork snapped, sending a flaming marshmallow directly onto my favorite canvas sneaker. I sat there on the grass, scraping sticky, blackened goo off my shoe with a twig while everyone else happily munched on their perfect graham cracker sandwiches.

That shoe was never the same.

But it taught me that traditional s'mores are a logistical nightmare for crowds. Cold banana slices release excess moisture, creating a watery puddle that breaks the chocolate's emulsion.

The fix is incredibly simple: we caramelize the bananas first in a cast-iron skillet to lock in their natural sugars and evaporate that excess water. This step triggers the Maillard reaction, transforming the harsh, raw banana starch into a rich, jammy base. It creates a stable foundation that clings beautifully to the melting chocolate without turning your dip into a soup.

Trust me, this works.

If you love the classic campfire flavor profile but want something in a sliceable form, check out my S'mores Cookie Bars. It is hands down the easiest way to feed a crowd without the sticky mess. Or, if you are looking for a cooler option for hot summer days, my S’mores Icebox Cake is a fantastic make-ahead alternative.

Ingredients

• 3 ripe bananas, sliced into 1/2-inch rounds
• 1 tablespoon unsalted butter
• 1 tablespoon light brown sugar
• 1.5 cups semi-sweet chocolate chips
• 1/2 cup milk chocolate chips
• 1 bag (10 oz) regular-sized marshmallows
• 1/4 cup maraschino cherries, drained and patted dry
• 1/4 cup chopped toasted peanuts
• 1/2 teaspoon Diamond Crystal kosher salt
• Graham crackers and vanilla wafers for serving

Directions

1. Preheat your oven to 375°F (190°C).
2. Melt the butter in an 8-inch or 10-inch cast-iron skillet over medium heat. Tap your wooden spoon against the side of the pan to clear off any excess butter.
3. Add the sliced bananas and brown sugar to the skillet. Sauté for about 3 to 4 minutes until the bananas are slightly caramelized and golden brown, turning them gently so they do not turn to mush.
4. Remove the skillet from the heat. Sprinkle the Diamond Crystal kosher salt evenly over the caramelized bananas.
5. Pour the semi-sweet and milk chocolate chips directly over the banana layer, spreading them into an even layer.
6. Arrange the marshmallows closely together on top of the chocolate chips, covering the entire surface.
7. Bake for 8 to 10 minutes, or until the marshmallows are puffed and golden brown on top. Keep a close eye on the oven during the last 2 minutes to prevent the marshmallows from burning.
8. Remove from the oven and immediately top with the drained maraschino cherries and chopped toasted peanuts to complete the banana split look. Serve warm with graham crackers.

Notes

• I highly recommend using Diamond Crystal kosher salt; if you are using Morton's kosher salt or fine table salt, cut the measurement in half (use 1/4 teaspoon) to avoid over-salting.
• Caramelizing the bananas first is crucial because it breaks down the complex starches into simple sugars, while simultaneously evaporating excess water that would otherwise break the chocolate's delicate fat-and-sugar emulsion.
• Do not walk away from the oven during the final minutes of baking; marshmallows transition from perfectly toasted to a blackened, bitter mess in a matter of seconds.
• Note that after a day in the fridge, the melted chocolate will solidify into a firm block and the marshmallows will lose their airy, toasted texture, making reheating necessary to restore the dip's gooey consistency.
• If you are using a cast-iron skillet, ensure it is well-seasoned; otherwise, the sugar from the caramelized bananas can cling to the metal and become incredibly stubborn to clean.

Serving Suggestions

This dip is best enjoyed straight from the warm skillet, surrounded by an array of fun dippers.

• Serve this dip alongside a platter of salty pretzel twists to create a delicious sweet-and-salty contrast.
• Offer fresh fruit skewers with strawberries and pineapple chunks to cut through the rich sweetness of the toasted marshmallows.
• Pair it with a cold glass of milk or a hot cup of black coffee to balance the decadent chocolate layers.
• If you want a fun griddle-based alternative for your next campout, try making a S'mores Quesadilla instead.

Storage and Reheating

If you somehow end up with leftovers, scrape them into an airtight container and pop them in the fridge. The chocolate will harden back into a solid shell, and the marshmallows will shrink into a slightly chewy, dense layer.

Do not lose hope.

To bring this dip back to life, you cannot just microwave it on high power, or you will end up with seized chocolate and exploded marshmallows. Instead, place the leftovers in an oven-safe dish, cover it with foil, and warm it at 300°F (150°C) for about 10 minutes. This gentle heat melts the fat in the chocolate matrix without scorching the delicate sugars on top.

Once the chocolate is glossy and melted, give it a good stir to recombine the layers. It won't look as pretty as day one, but it tastes just as heavenly.

Ingredient Substitutes

If you find yourself missing a few ingredients, do not panic.

1. Semi-Sweet Chocolate Chips: You can substitute dark chocolate chips or chopped chocolate bars if you prefer a less sweet, more intense cocoa flavor.
2. Maraschino Cherries: Fresh sweet cherries, pitted and halved, work beautifully if you want to avoid artificial dyes and syrups.
3. Toasted Peanuts: Swap in toasted pecans or sliced almonds if you have a peanut allergy, or omit the nuts entirely.
4. Graham Crackers: Vanilla wafers, digestive biscuits, or even salty potato chips make fantastic alternative dippers.

Gather your friends, grab a box of graham crackers, and let everyone dive in while it is still warm and stretchy. Just remember to let the skillet cool for a minute before you place it on the table—no one needs a repeat of my flaming marshmallow shoe incident.
