Ingredients
Detailed Ingredient List
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
- 1 cup mini marshmallows
- 1/2 cup chocolate chips (for topping)
The first key to making these fudgy brownies is to gather all your ingredients. Start with unsalted butter. Melt it until it’s warm, not hot. Next, you will need granulated sugar. This adds sweetness and helps the brownies rise.
You will use four large eggs. They bring moisture and richness to your mix. Don’t forget the vanilla extract. It adds a warm flavor that enhances the chocolate.
For the dry mix, grab all-purpose flour and unsweetened cocoa powder. These two give the brownies their structure and deep chocolate taste. Add in salt and baking powder. The salt balances the sweetness while the baking powder helps the brownies rise.
Finally, we add the fun part—mini marshmallows and chocolate chips. These toppings create a gooey layer that makes each bite special.
Equipment Needed
- 9x13 inch baking pan
- Mixing bowls
- Whisk and spatula
You will need a 9x13 inch baking pan for the perfect brownie shape. Make sure to grease it or line it with parchment paper. This helps with easy removal.
Prepare mixing bowls. One for wet ingredients and one for dry. A whisk works well for mixing. Use a spatula to fold the batter. This keeps it smooth and creamy without overmixing.
Once you have everything ready, you're all set to create these delicious fudgy brownies!

Step-by-Step Instructions
Preparing the Oven and Baking Pan
- Preheat oven to 350°F (175°C).
- Grease or line a 9x13 inch baking pan with parchment paper.
First, heat your oven. This helps your brownies bake evenly. Greasing or lining the pan makes it easy to take the brownies out later.
Mixing Wet Ingredients
- Combine melted butter and granulated sugar.
- Incorporate eggs and vanilla extract.
In a large bowl, mix melted butter and sugar. Stir until smooth and creamy. Then, add the eggs one by one. Mix after each egg to blend well. Finally, add the vanilla extract for flavor.
Mixing Dry Ingredients and Combining
- Whisk together dry ingredients.
- Gradually add dry mixture to wet mixture.
In another bowl, whisk together flour, cocoa powder, salt, and baking powder. This keeps your brownies fluffy. Slowly add the dry mix to the wet ingredients. Stir gently until just combined. Avoid overmixing to keep them fudgy.
Baking the Brownies
- Pour batter into prepared pan.
- First baking session (25-30 minutes).
- Adding toppings and final bake (5-7 minutes).
Now, pour the brownie batter into your pan. Spread it evenly. Bake for 25-30 minutes. Check with a toothpick; it should have a few moist crumbs. After baking, sprinkle mini marshmallows and chocolate chips on top. Bake for another 5-7 minutes until the marshmallows puff up.
Tips & Tricks
Achieving the Perfect Fudgy Texture
To get that perfect fudgy texture, avoid overmixing the batter. Mix just until you see no dry flour. This keeps your brownies moist and chewy.
To test for doneness, insert a toothpick into the center. If it comes out with a few moist crumbs, your brownies are ready. If it has wet batter, bake a bit longer.
Presentation Ideas
For a delightful serving suggestion, drizzle warm chocolate sauce over each brownie square. This adds a rich, extra layer of flavor. You can also garnish with extra mini marshmallows. They will look cute and taste great!
Storing Leftovers
For best storage, place brownies in an airtight container. This keeps them fresh and soft. Store them at room temperature for up to three days.
If you want to keep them longer, consider freezing. Wrap each brownie in plastic wrap, then place them in a freezer bag. Thaw them at room temperature before enjoying.
Pro Tips
- Use Quality Chocolate: Choose high-quality cocoa powder and chocolate chips for a richer flavor in your brownies.
- Don’t Overmix: Mix the batter until just combined to keep your brownies fudgy and tender.
- Cool Before Cutting: Allow the brownies to cool completely in the pan for cleaner cuts and better texture.
- Experiment with Toppings: Feel free to add nuts, caramel, or different types of chocolate for a unique twist!
Variations
Flavor Enhancements
You can take these fudgy brownies to the next level. Adding nuts brings a nice crunch. I love using walnuts or pecans. You can also swirl in caramel for a sweet twist. Imagine that gooey caramel blending with chocolate. It's a match made in heaven!
Another fun idea is to use flavored chocolates for the topping. Try dark chocolate, white chocolate, or even mint chocolate. Each choice adds a new taste to the brownies. You can experiment and find your favorite flavor!
Gluten-Free Option
If you need a gluten-free option, you can easily swap the all-purpose flour. Use a gluten-free flour blend instead. It works great and keeps the brownies fudgy. Just make sure your blend has a good mix of starches and flours. This way, your brownies will still rise and taste fantastic.
Vegan Adaptation
For a vegan version, you can replace the eggs. Use flaxseed meal or applesauce instead. Mix one tablespoon of flaxseed with three tablespoons of water. Let it sit for a few minutes to thicken. This acts as a great egg substitute.
You can also use vegan butter instead of regular butter. This keeps the rich taste while making it dairy-free. Your brownies will still be soft and tasty, just like the original recipe!
Storage Info
Keeping Your Brownies Fresh
To keep your fudgy brownies fresh, store them at room temperature. Place them in an airtight container. This method keeps them soft and chewy. If you live in a hot area, put them in the fridge. This will help them last longer but might change the texture. Use a glass or plastic container with a tight lid. This keeps moisture in and air out.
Freezing Brownies
To freeze your brownies, cut them into squares first. Wrap each piece tightly in plastic wrap. Then, place them in a freezer bag. Make sure to remove any air before sealing. This helps prevent freezer burn. Your brownies can last up to three months in the freezer. When you're ready to enjoy them, take out the brownies and let them thaw at room temperature. This makes them soft again. If you're in a hurry, you can warm them in the microwave for a few seconds. Enjoy your sweet treat anytime!
FAQs
Can I make these brownies ahead of time?
Yes, you can make these brownies ahead of time. Bake them, then let them cool. Store them in an airtight container at room temperature for up to three days. For longer storage, freeze them. Wrap each brownie in plastic wrap. Then, place them in a freezer bag. They can last up to three months in the freezer. Thaw them overnight in the fridge before serving.
How can I fix dry brownies?
If your brownies turn out dry, don’t worry! You can add moisture back easily. Try adding a bit of milk or cream. Warm it slightly and mix it in with a fork. You can also layer them with ice cream or whipped cream. This adds flavor and moisture. For next time, reduce baking time by a few minutes. Check doneness early to keep them fudgy.
Can I use regular marshmallows instead of mini?
Yes, you can use regular marshmallows instead of mini ones. Just cut them into smaller pieces. This helps them melt evenly on top of the brownies. Mini marshmallows melt faster and spread more evenly, though. So, the texture might change slightly. If you enjoy a gooey topping, regular marshmallows work just fine!
