Marshmallow Brownie Ingredients
-
For the Brownie Batter
• White Granulated Sugar – Provides sweetness and moisture; can be substituted with brown sugar for a richer flavor.
• Large Eggs – Essential for binding and adding richness; be sure to use two for the best results.
• Egg Yolk – Enhances the fudginess; if you want extra richness, add another large egg.
• Unsalted Butter (melted) – Contributes to a deep fudge texture; coconut oil can be a great dairy-free alternative.
• Pure Vanilla Extract – Infuses a lovely aroma and sweetness; vanilla paste is a delicious substitute.
• Oil (Canola or Vegetable) – Keeps the brownies moist; any neutral-flavored oil will work here.
• All-Purpose Flour – Provides the structure of the brownies; swap with gluten-free flour for a gluten-free option.
• Unsweetened Cocoa Powder (Dutch process) – Adds an intense chocolate flavor; regular cocoa powder is a fine alternative.
• Cornstarch – Ensures the brownies are chewy; you can skip it if you don’t have any.
• Salt – Balances the sweetness; essential for enhancing the overall flavor.
• Semi-Sweet Chocolate Chips – Gives bursts of rich chocolate flavor; dark chocolate chips can deepen the delight. -
For the Marshmallow Swirl
• Marshmallow Creme – Adds that fluffy, sweet touch; consider experimenting with flavored marshmallows for a fun twist.
How to Make Marshmallow Brownies
-
Preheat the Oven: Begin by preheating your oven to 325°F (163°C). Prepare a 9×9-inch baking pan by greasing it with nonstick spray and lining the bottom with parchment paper for easy removal.
-
Sift the Dry Ingredients: In a medium bowl, sift together the all-purpose flour, unsweetened cocoa powder, cornstarch, and salt. This helps ensure a smooth brownie texture free of lumps.
-
Beat the Eggs and Sugar: In a large mixing bowl, use an electric mixer to beat the sugar, large eggs, and egg yolk on high speed for about 5 minutes until the mixture becomes pale and thick. This aerates the mixture, giving your brownies a lovely rise.
-
Mix in Wet Ingredients: Slowly add the melted butter, canola oil, and pure vanilla extract to the egg mixture. Mix on low speed until everything is well combined and smooth.
-
Combine Dry Ingredients: Gradually mix in the sifted dry ingredients until just combined. Be gentle here to avoid overmixing; it’s okay if there are a few small flour streaks remaining. Fold in the semi-sweet chocolate chips for those lovely chocolatey bursts.
-
Prepare for Baking: Pour the brownie batter into the prepared baking pan, spreading it evenly. Melt the marshmallow fluff for about 15-20 seconds in the microwave until it’s spreadable, then dollop it on top of the batter. Use a knife to gently swirl it in—this creates that delightful marshmallow ribbon.
-
Bake the Brownies: Place the pan in the oven and bake for 45-55 minutes. Check for doneness by inserting a toothpick; it should come out slightly wet, indicating a fudgy center.
-
Cool and Serve: Allow the brownies to cool completely on a wire rack before cutting them into squares. This cooling period will ensure you achieve beautifully clean edges when slicing.
Optional: Serve with a sprinkle of sea salt on top for a contrasting flavor boost.

How to Store and Freeze Marshmallow Brownies
Room Temperature: Store your marshmallow brownies in an airtight container at room temperature for up to 5 days to keep them moist and delicious.

Freezer: For longer storage, freeze individual brownie squares in an airtight container or freezer bag for up to 30 days. Remember to separate layers with parchment paper to prevent sticking.
Reheating: When you’re ready to indulge, thaw at room temperature or warm in the microwave for about 15-20 seconds for that gooey, fudgy goodness!

How should I store leftover brownies?
Store your fudgy marshmallow brownies in an airtight container at room temperature for up to 5 days to preserve their moisture. If you prefer them chilled, they can go in the fridge for about a week, just make sure they are properly sealed to avoid absorbing any strong odors from your fridge.
Can I freeze marshmallow brownies?
Absolutely! These brownies freeze beautifully. Cut them into individual squares and place them in an airtight container or freezer bag, separated by sheets of parchment paper to prevent sticking. They can be stored for up to 30 days; simply thaw at room temperature or warm them in the microwave for 15-20 seconds to enjoy a fresh-out-of-the-oven experience.
What if my brownies come out too cakey or dry?
If your brownies end up cakey, it could be from overmixing once you added the dry ingredients or baking too long. For the next batch, ensure you mix gently when folding in the flour and check for doneness with a toothpick; it should come out slightly wet for that fudgy texture you want. Also, remember that every oven is different, so you might need to adjust the baking time slightly.

How can I ensure my brownies have a shiny crackly top?
To achieve that sought-after shiny crackly crust, make sure to beat your eggs and sugar together until the mixture is light and fluffy (about 5 minutes). This step helps to incorporate air into the batter, which contributes to the rise and crackle when baked. Enjoy your baking!
