Servings: 9 squares
- 1 box of brownie mix, preferably Ghirardelli
- 1 egg
- 5 tablespoon butter, melted
- ¼ cup milk
- 1 cup Nutella (chocolate hazelnut spread)
- 1 cup marshmallow fluff
- 1 ½ teaspoon vanilla extract
- ½ cup dark chocolate chunks or nuts of your choice
- Flaky salt, topping (optional)
Preheat your oven to 325 degrees.
In a mixing bowl, combine brownie mix, egg, butter, vanilla extract and milk and stir until just combined. Fold in the chocolate chips or nuts gently without over mixing.
Grease a 9”x9” baking pan with butter or cooking spray. Line with parchment paper for easy release. Pour in the brownie batter and evenly smooth it in the pan.
Take the Nutella and marshmallow fluff and scoop spoons of both, alternating, over the top of the batter.
Take a butter knife or skewer and swirl the Nutella and marshmallow fluff together gently to create a marbled effect.
Place the baking dish in the oven and bake for 35-40 minutes. The brownies will still be a little fudgey on the inside. They will continue to set once taken out of the oven.
Remove them from the oven and let them cool in the pan for a few minutes. Then, transfer them to a wire rack to cool completely. Once cooled, sprinkle some flaky salt over the top. Cut the brownies into 9 even squares and enjoy!
We find that using the Ghirardelli boxed brownie mix gets the best tasting brownies, but feel free to use whatever kind of mix you prefer. The baking times may vary slightly if using a different brand.
We strongly recommend lining your baking pan with parchment paper with the flaps hanging over the sides. This is a great way to ensure your brownies don’t stick to the pan and come out easily without breaking from the pan.
It may be a little bit harder to tell that the brownies have finished baking because a toothpick will likely not come out clean until they have over cooked. Check around the 35 minute mark and if the toothpick is still very raw in the center then give it a few more minutes. The brownies will continue to cook in the pan out of the oven for a little bit. This will provide the fudgy and gooey brownie while still crisp on the outside.
We love adding a little crunch to our brownies, so either nuts or dark chocolate chips. These are already on the sweet side, so dark chocolate is best. Toasted chopped hazelnuts, pecans or walnuts are great additions to these as well.
If you want to add a deeper flavor, substitute espresso or strong coffee for half of the milk to get an even richer chocolate flavor.
Feel free to add more Nutella or marshmallow fluff if you feel like it isn’t enough or less if you don’t want as much.
