Ingredients
Main Ingredients

- 1 cup packed brown sugar
- 4 large eggs
- 1 teaspoon vanilla extract

I love these brownies because they mix rich chocolate with soft marshmallows. Each bite is a treat! Let’s break down the ingredients.
You need one cup of unsalted butter. This adds a creamy base. The butter should be melted first, which helps blend the sugars well. You’ll also use one cup each of granulated and brown sugar. Granulated sugar gives sweetness, while brown sugar adds depth and moisture.
Next, you will need four large eggs. Eggs help bind the batter and create a nice texture. Remember to mix them in one at a time to keep everything smooth.
Then, one teaspoon of vanilla extract adds amazing flavor. You’ll also need one cup of all-purpose flour and one cup of unsweetened cocoa powder. These dry ingredients are key for that rich brownie taste.
Don’t forget the leavening agents! Use 1/2 teaspoon of baking powder and 1/2 teaspoon of salt. These help your brownies rise perfectly.
Now, the fun part! You’ll add one cup of dark chocolate chips for richness. And, you can’t skip the mini marshmallows! They melt and create gooey pockets inside the brownies. If you want an extra touch, sprinkle some sea salt on top before serving. It enhances the chocolate flavor beautifully.
With these ingredients, you are ready to make something delicious!

Step-by-Step Instructions
Preparation
- Preheat the oven to 350°F (175°C).
- Grease and line the baking pan with parchment paper.
Mixing the Batter
- Melt the butter in a medium saucepan over low heat.
- Stir in granulated sugar and brown sugar until mixed well.
- Add the eggs one by one and mix in the vanilla extract.
- In a separate bowl, sift together flour, cocoa powder, baking powder, and salt.
- Gradually fold the dry ingredients into the wet mixture until just combined.
- Fold in dark chocolate chips evenly throughout the batter.
Assembling the Brownies
- Pour half the batter into the prepared baking pan and spread it evenly.
- Pre-bake for 10 minutes to form a base layer.
- Remove from the oven and sprinkle mini marshmallows on top.
- Spoon the remaining batter over the marshmallows and spread gently.
- Return to the oven and bake for 20-25 minutes.
- Check doneness with a toothpick; it should come out with a few moist crumbs.
- Let cool in the pan for about 10 minutes before lifting out.
- Allow to cool completely on a wire rack before cutting into squares.
- Optional: sprinkle with sea salt before serving for added flavor.
Tips & Tricks
Perfecting Texture
- Use quality chocolate for better flavor. It makes a big difference in taste.
- Don’t overmix the batter. Mixing too much can make brownies tough.
Achieving the Right Bake
- Monitor baking time closely. Ovens can vary, so keep an eye on them.
- Use a toothpick test for doneness. If it comes out with moist crumbs, they are ready.
Enhancing Flavor
- Add a sprinkle of sea salt before serving. It boosts the chocolate taste.
- Consider incorporating nuts for added crunch. Walnuts or pecans work well in this recipe.
Pro Tips
- Use Quality Chocolate: Opt for high-quality dark chocolate chips for a richer flavor that enhances the overall taste of your brownies.
- Don’t Overmix: Once you combine the wet and dry ingredients, mix just until incorporated. Overmixing can lead to tough brownies.
- Check for Doneness: Insert a toothpick into the center; it should come out with a few moist crumbs. If it’s wet, bake for a few more minutes.
- Let Them Cool: Allow the brownies to cool completely before cutting. This helps them set and makes slicing easier.
Variations
Flavor Boosts
You can add fun twists to your brownies. Try swapping vanilla extract for peppermint extract. This gives a fresh, minty taste. You can also drizzle a swirl of caramel on top. The sweet caramel pairs well with rich chocolate.
Healthier Options
Want a lighter version? Use coconut oil instead of butter. This change keeps the brownies moist and adds a slight coconut flavor. If you wish to cut sugar, use a sugar substitute. Look for options like stevia or monk fruit.
Dietary Modifications
If you're gluten-free, use alternative flours like almond or coconut flour. These flours work well and keep the brownies tasty. For a vegan version, replace eggs and butter. You can use flax eggs and coconut oil. These swaps keep the brownies soft and delicious.
Storage Info
Short-Term Storage
To keep your Dark Chocolate Chip Marshmallow Brownies fresh, store them at room temperature. Place the brownies in an airtight container. This helps retain moisture and flavor. Make sure to let them cool completely before storing. If you have leftovers, they can last about 3 to 4 days.
Long-Term Storage
For longer storage, you can freeze brownies. Wrap them tightly in plastic wrap, then place in a freezer bag. This helps prevent freezer burn. Your brownies can last for up to 3 months in the freezer. When you’re ready to enjoy them, thaw them in the fridge overnight. This method keeps them soft and tasty.
Reheating Suggestions
To warm brownies without drying them out, aim for a gentle heat. You can use a microwave for quick warming. Heat them for 10-15 seconds at a time. Check often to avoid overheating. Alternatively, use an oven set to 350°F (175°C). Place the brownies on a baking sheet. Heat for about 5 to 10 minutes. Both methods will help restore their gooey texture.
