Ingredients:
1 (7–7.5 oz) jar marshmallow fluff.
3 cups mini pretzels (lightly crushed) or graham cracker pieces.
1 cup semi-sweet chocolate chips.
4 tablespoons unsalted butter (melted).
Prep: Preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish.
Layer 1: Dump the entire jar of marshmallow fluff into the dish and spread it into an even layer.
Layer 2: Sprinkle the crushed pretzels or graham crackers over the fluff, pressing them down slightly.
Layer 3: Scatter the chocolate chips evenly over the top.
Drizzle the melted butter over the entire surface to help the toppings toast.
Bake until the marshmallow is puffy and the chocolate is melted (usually about 10–15 minutes).
If you prefer a no-bake version you can add 8oz of cream cheese and splash of vanilla to the fluff and layer as above and refrigerate it and use it as a fruit dip.
