This little 4-ingredient oven-baked marshmallow fluff dessert is the kind of thing you throw together on a tired weeknight when you still want to spoil everyone a bit. It reminds me of the quick bakes we used to make for church youth group—simple pantry ingredients, big payoff, and a pan scraped clean in minutes.
Glass baking dish filled with marshmallow fluff dessert on a farmhouse table
You literally dump a whole jar of marshmallow fluff into a glass baking dish, scatter in a few helpers, and let the oven do the work. It comes out like a gooey, toasty, caramel-kissed marshmallow cobbler that feels right at home on any Midwestern table.
Serve this warm right out of the baking dish, with a big spoon and small bowls so everyone can scoop up the gooey center and those toasty brown edges. A scoop of vanilla ice cream or a dollop of whipped cream on top is just perfect, since the cool creaminess tames the sweetness a bit.
Warm serving of marshmallow fluff dessert with melting vanilla ice cream
Strong coffee, cold milk, or hot cocoa all pair nicely. This is rich, so think of it as a little sundae base—add a few fresh berries or sliced bananas if you like, but honestly, most families will be perfectly happy just chasing every last sticky bite out of the pan.
4-Ingredient Baked Marshmallow Fluff Dessert
Servings: 8
Ingredients
1 (7–7.5 oz) jar marshmallow fluff or marshmallow creme
3 cups mini pretzels, lightly crushed
1 cup semi-sweet chocolate chips
4 tablespoons unsalted butter, melted
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch glass baking dish with a bit of butter or nonstick spray so the marshmallow doesn’t cling too hard to the corners.
Simple ingredients for marshmallow fluff dessert arranged on a kitchen counter
Dump the entire jar of marshmallow fluff into the center of the baking dish. Use a spatula to scrape every bit from the jar, then gently spread the fluff into an even layer that reaches all the way to the edges. It will be sticky and a little stubborn—that’s just fine.
Sprinkle the mini pretzels over the top of the marshmallow fluff in an even layer. Use your hand to gently press them down so they nestle into the fluff but still sit mostly on top; this gives you a nice salty crunch later.
Pretzels pressed into marshmallow fluff in a square baking dish
Scatter the chocolate chips evenly over the pretzel layer, making sure you get some in all the corners so every scoop has a little chocolate in it.
Drizzle the melted butter slowly and evenly over the entire surface. Try to hit as much of the pretzels and chocolate as you can; the butter helps everything toast up and meld together into a caramelized, crunchy topping.
Place the baking dish on the middle rack of the preheated oven and bake for 15–20 minutes, or until the edges of the marshmallow fluff are deeply golden and puffed, the chocolate is melted, and the pretzels smell toasty. Keep a close eye during the last few minutes so the marshmallow browns but does not burn.
