Ingredients
1/2 cup butter, melted
3/4 cup brown sugar
1/4 cup granulated sugar
1 egg
1 tsp vanilla extract
1 1/4 cups all-purpose flour
1/2 tsp baking soda
1/2 tsp salt
1 cup chocolate chunks
1 cup mini marshmallows
Extra chocolate pieces for topping

Instructions

Start by preheating your oven to 180°C (350°F).

In a bowl, mix melted butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla extract, then mix until fully combined.

Stir in flour, baking soda, and salt until a soft dough forms.

Fold in chocolate chunks and half of the marshmallows.

Press the dough evenly into a greased skillet or baking dish.

Top with remaining marshmallows and extra chocolate pieces.

Bake for 18–22 minutes until the edges are golden and the center is still soft.

Let it cool slightly, then serve warm for that perfect gooey texture.

Serving

Serve straight from the skillet with a spoon or scoop into bowls. Add vanilla ice cream on top for an extra indulgent treat.

Storage

Store leftovers covered at room temperature for up to 2 days or refrigerate for up to 4 days. Reheat slightly before serving.
