Preheat your oven to 350°F (175°C). Lightly grease a 9x9-inch baking pan and line it with parchment paper, leaving overhangs on the sides for easy removal.
In a medium saucepan, melt the butter over low heat. Remove from the heat and stir in the granulated sugar and brown sugar until combined.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
Add the eggs and vanilla extract to the butter-sugar mixture and whisk until smooth. Gradually fold in the dry ingredients until a thick batter forms.
Spread the batter evenly into the prepared baking pan. Bake for 15-18 minutes, or until the edges are just set but the center is still slightly soft.
Remove the pan from the oven and immediately sprinkle the mini marshmallows evenly over the top. Return to the oven and bake for an additional 2-3 minutes, or until the marshmallows are just starting to puff up.
Meanwhile, in a microwave-safe bowl, combine the chocolate chips and sweetened condensed milk. Microwave in 30-second intervals, stirring between each, until the chocolate is melted and the mixture is smooth.
Carefully pour the chocolate mixture over the marshmallows, spreading it evenly with a spatula.
Allow the bars to cool completely at room temperature, then transfer them to the refrigerator for at least 1 hour to set.
Once chilled, use the parchment paper overhang to lift the bars out of the pan. Slice into 16 squares and serve. Store leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
