Step‑by‑Step Instructions for Fudgy Marshmallow Brownies

Step 1: Prep Oven and Pan
Preheat your oven to 325°F (163°C). Take a 9×9-inch baking pan and spray it with non-stick cooking spray. Next, line the bottom and sides with parchment paper for easy removal, and give it another light spritz of spray. This step ensures your fudgy marshmallow brownies will come out perfectly without sticking.

Step 2: Mix Dry Ingredients
In a medium bowl, sift together the all-purpose flour, unsweetened cocoa powder, cornstarch, and salt. This aeration process helps create a lighter texture in your brownies. Once combined, set this mixture aside as you move on to preparing the wet ingredients, keeping your workspace organized and ready for the next steps.

Step 3: Beat Sugar and Eggs
In a large mixing bowl, combine the granulated sugar, large eggs, and egg yolk. Using an electric mixer, beat on high for about 5 minutes until the mixture is pale and fluffy. The air incorporated during this step will give your marshmallow brownies a delightful lift. Make sure to scrape down the sides of the bowl for even mixing.

Step 4: Combine Wet Ingredients
Lower the mixer speed and gently mix in the melted butter, oil, and pure vanilla extract. Beat until just combined, ensuring no streaks of butter remain. This creates a rich base for your fudgy marshmallow brownies. At this stage, the batter should be smooth and glossy, signaling that you’re ready to combine it with the dry ingredients.

Step 5: Combine Mixtures
Gradually add the dry ingredients to the wet mixture. Use a spatula to fold the ingredients together until just combined—be careful not to overmix, as this can affect the fudge-like texture. Once incorporated, add the semi-sweet chocolate chips to the batter, ensuring they’re evenly distributed for delightful bursts of chocolate in each bite.

Step 6: Swirl in Marshmallow
Pour the brownie batter into your prepared baking pan, smoothing it evenly with a spatula. Next, dollop melted marshmallow crème across the top. Using a knife, gently swirl the marshmallow into the batter for that iconic fudgy marshmallow brownie look. Don’t over-swirl; you want to achieve a marbled effect without fully mixing.

Step 7: Bake
Place the pan in the preheated oven and bake for 45 to 55 minutes. You’ll know your fudgy marshmallow brownies are ready when the edges look firm but the center is still slightly underbaked and a toothpick inserted comes out with a few wet crumbs. Keep an eye on them in the last few minutes, as oven temperatures can vary.

Step 8: Cool Before Serving
Once baked, remove the brownies from the oven and let them cool in the pan on a wire rack. Allow them to cool completely for easier cutting, which can take about 30 minutes. This cooling period helps the brownies set, ensuring clean edges when you slice into your gooey marshmallow masterpieces.

What to Serve with Fudgy Marshmallow Brownies

Indulging in these gooey delights is even better when paired with complementary sides that enhance their sweet chocolatey goodness.

Vanilla Ice Cream: The creamy chill melts into the warm brownies, creating a decadent contrast. This classic pairing is an irresistible way to enjoy your marshmallow brownies.
Whipped Cream: Light and airy, whipped cream adds a touch of elegance, balancing the rich chocolate with its softness. A dollop on top brings heaven to each bite!
Fresh Berries: Strawberries or raspberries offer a tartness that cuts through the sweetness, contributing a burst of color and freshness to your dessert plate.
Chocolate Sauce: Drizzle warm chocolate sauce over the top for an extra layer of indulgence. It intensifies the chocolate experience and looks stunning!
Cola or Root Beer Floats: A fizzy beverage like cola or root beer with a scoop of ice cream mirrors the brownie’s textures and flavors, transforming dessert into a delightful celebration.
Coffee or Espresso: The bold flavors of coffee pair wonderfully with fudgy marshmallow brownies, enhancing the chocolate notes while providing a warm, cozy vibe to your dessert experience.

Embrace these pairings to elevate the delightful experience of your marshmallow brownies and create a complete, satisfying meal!

Expert Tips for the Best Marshmallow Brownies

Mixing Time Matters: Ensure you beat the sugar and eggs for the full 5 minutes to achieve that light, airy texture in your marshmallow brownies.
Temperature Check: Oven temperatures can vary; check your brownies a few minutes early to prevent overbaking for the perfect fudgy center.
Pan Size Precision: For thicker brownies, use an 8×8-inch pan and adjust the baking time accordingly to avoid thin, overcooked edges.
Cool Completely: Allow brownies to cool fully before cutting for cleaner edges and to enhance the fudge-like texture—patience pays off!
Customize Creatively: Feel free to experiment with different chocolate chips or add nuts for a delightful crunch and personalization to your marshmallow brownies.

How to Store and Freeze Marshmallow Brownies

Reheating: To enjoy your marshmallow brownies warm, reheat in the microwave for about 10-15 seconds, keeping a close eye to avoid melting the marshmallow layer too much.

Marshmallow Brownies Recipe FAQs

What type of marshmallow crème should I use?
Absolutely! For the best results, use a high-quality marshmallow crème. Brands like Jet-Puffed are widely available and perfect for achieving that gooey swirl. If you can’t find marshmallow crème, you can substitute with marshmallow fluff for a similar effect in your fudgy marshmallow brownies.

How do I know if my brownies are baked properly?
To ensure your brownies are baked just right, keep an eye on them as they approach the end of the baking time. You want the edges to look firm but the center should still be slightly jiggly. Insert a toothpick into the center; it should come out with a few wet crumbs clinging to it—this indicates a perfectly fudgy texture.

How should I store leftover brownies?
Store your leftover marshmallow brownies in an airtight container at room temperature for up to 5 days. If you want to keep them fresher for longer, refrigerate them for up to a week. Just remember to bring them back to room temperature for the best taste and texture!

Can I freeze these brownies?
Of course! To freeze your brownies, first cut them into individual pieces. Wrap each piece tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 30 days. When you’re ready to indulge, let them thaw at room temperature or microwave for 10-15 seconds for a warm treat!

What can I do if my brownies are too cakey?
If you find your brownies turned out too cakey, it might be due to overmixing or baking them too long. Next time, be mindful to mix just until combined and bake only until a toothpick comes out with a few wet crumbs. You can also add an extra egg yolk for added moisture and richness in future batches.

Are these brownies suitable for gluten-free diets?
Very! You can easily make these marshmallow brownies gluten-free by substituting all-purpose flour with a 1:1 gluten-free flour blend. Make sure to also check that your other ingredients, like baking soda and chocolate chips, are gluten-free. Enjoy without worry!
