This 4-ingredient oven baked marshmallow pumpkin dessert is the kind of playful, nostalgic treat that comes together with almost no effort and delivers big holiday-candy-shop flavor. Using raw unwrapped orange marshmallow pumpkins as the star ingredient gives it a festive fall look, while a few pantry staples help turn simple candy into a warm, gooey dessert that feels part candy bake, part quick dessert dip, and part old-fashioned potluck favorite.

Serve this warm with vanilla ice cream, shortbread cookies, graham crackers, apple slices, or pretzel thins for a sweet-and-salty contrast. It also fits nicely on a Halloween dessert table or Thanksgiving sweets spread, where the bright orange color stands out beautifully alongside spiced cider, coffee, or hot chocolate.

Ingredients

16 ounces raw unwrapped orange marshmallow pumpkins

4 tablespoons unsalted butter, melted
1/4 cup light brown sugar, packed
1 teaspoon ground cinnamon

Directions

1. Preheat the oven to 350°F and lightly butter or spray an oven-safe glass baking dish.

2. Add the raw unwrapped orange marshmallow pumpkins to the prepared baking dish in an even layer.

3. Drizzle the melted butter over the marshmallow pumpkins, then sprinkle the brown sugar and cinnamon evenly across the top.

4. Bake for 10 to 15 minutes, until the marshmallow pumpkins are puffed, softened, and beginning to melt together, with lightly caramelized edges.

5. Let the dessert cool for 5 minutes, then serve warm as-is or scoop it onto plates with graham crackers, apple slices, or a small scoop of vanilla ice cream.

Variations & Tips

Add crunch: For a little texture, scatter chopped pecans or walnuts over the top before baking. The nuts toast lightly in the oven and balance the soft, gooey candy base.

Make it spicier: Add a pinch of nutmeg or pumpkin pie spice along with the cinnamon for a deeper fall flavor. This is a simple way to make the dessert taste a bit more layered without adding extra work.

Use it as a dip: If you want a more shareable party dessert, bake it in a smaller dish so the melted mixture stays thicker and scoopable. Set it out with cookies, pretzels, and fruit for dipping.

Watch the bake time: Marshmallow candy can go from perfectly soft to overdone quickly, so start checking at the 10-minute mark. You want it melted and puffy, not dark or hardened around the edges.

Serve warm: This dessert has its best texture shortly after baking, when the marshmallows are still soft and stretchy. If it cools too much, a brief warm-up in the oven will loosen it again.
