Would you like to save this?
We first made these on a snow day when all we had was a box of hot cocoa mix and a chocolate craving. The results were so good, we made them again the next weekend, and added extra marshmallows! It’s now a winter tradition we look forward to every year.

Ingredients
- 1 cup unsalted butter 2 sticks
- 8 ounces semisweet chocolate morsels
- 1 ½ cups hot chocolate mix not sugar free
- 1 cup all purpose flour
- ½ teaspoon salt
- 4 large eggs
- 2 teaspoons vanilla extract
- 2 cups mini marshmallows
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper and lightly grease.

- Sprinkle mini marshmallows over the top and return to the oven for 2 to 3 minutes, just until puffed and lightly golden.
- Cool completely before cutting into squares.
Notes
- Don’t overbake; slightly underdone brownies stay fudgier.
- Want extra toasted marshmallows? Broil for 30 to 60 seconds, watching closely.
- Add chocolate chips or crushed peppermint for a festive twist.
