Step‑by‑Step Instructions for Ultra-Fudgy Marshmallow Brownies

Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (160°C). While it warms up, take a 9×9-inch baking pan and line it with parchment paper, allowing some overhang for easy removal later. This step is crucial for achieving the perfect texture in your marshmallow brownies, ensuring a clean release once they’re baked.

Step 2: Mix Dry Ingredients
In a medium bowl, sift together 1 cup of all-purpose flour, 1/2 cup of unsweetened cocoa powder, 1 teaspoon of cornstarch, and 1/4 teaspoon of salt. This mixture will help incorporate air and eliminate any lumps, creating a smooth brownie batter. Set the dry ingredients aside, giving you the perfect foundation for your ultra-fudgy marshmallow brownies.

Step 3: Beat Sugar and Eggs
In a large mixing bowl, combine 1 cup of white granulated sugar, 2 large eggs, and 1 egg yolk. Using a hand or stand mixer, beat on high speed for about 5 minutes until the mixture becomes pale and fluffy. This aeration is essential for achieving a shiny, crackly top on your marshmallow brownies, so don’t rush this crucial step!

Step 4: Add Wet Ingredients
Lower the mixer speed and gradually fold in 1/2 cup of melted unsalted butter, 1/4 cup of canola or vegetable oil, and 1 teaspoon of pure vanilla extract. Blend these ingredients until just combined, ensuring the mixture remains smooth and silky. This will add richness and moisture to your brownies, enhancing their fudginess.

Step 5: Combine Dry and Wet Mixtures
Now, gently fold the dry ingredient mixture into the wet batter until just combined—be careful not to overmix! Finally, stir in 1 cup of semi-sweet chocolate chips, letting them distribute evenly throughout your marshmallow brownies for pockets of melty chocolate goodness.

Step 6: Assemble the Brownies
Pour the brownie batter into your prepared baking pan, spreading it evenly. Next, take 1 cup of marshmallow creme and dollop it on top of the batter in various spots. With a knife, swirl the marshmallow fluff gently into the brownie mixture, creating an inviting pattern while ensuring some areas remain visible for that delicious gooeyness.

Step 7: Bake
Place the pan in the preheated oven and bake for 45-55 minutes. Keep an eye on them; they’re ready when a toothpick inserted into the center comes out with a few moist crumbs. This is the sweet spot for ultra-fudgy marshmallow brownies—don’t overbake!

Step 8: Cool and Cut
Once baked, remove your brownies from the oven and let them cool completely in the pan on a wire rack. This cooling period is crucial for easy cutting; aim for at least 30 minutes. Once cooled, lift the brownies out using the parchment overhang and cut them into squares to reveal the luscious marshmallow and chocolate layers inside.

Make Ahead Options

These Ultra-Fudgy Marshmallow Brownies are perfect for busy cooks who want to save time! You can prepare the brownie batter and refrigerate it for up to 24 hours before baking. Just mix all the ingredients (excluding the marshmallow fluff), cover the bowl tightly, and store it in the fridge to maintain freshness. When you’re ready to bake, pour the batter into your prepared pan, dollop with marshmallow fluff, and swirl as directed. For best results, let the brownies cool completely before cutting, as this will help keep their decadent fudginess intact. Enjoy all the deliciousness with minimal effort!

Ultra-Fudgy Marshmallow Brownies Recipe FAQs

What type of sugar is best for these brownies?
For the best results, I recommend using white granulated sugar, as it balances the rich cocoa flavor beautifully. If you’d like a more complex taste, you can substitute some of it with brown sugar. This adds a nice depth and moisture to the brownies.

How should I store my marshmallow brownies?
You can store your marshmallow brownies in an airtight container at room temperature for up to 5 days. If you prefer them chilled, you can keep them in the fridge for up to a week but allow them to reach room temperature before serving for the best experience.

Can I freeze my brownies, and how should I do it?
Absolutely! For long-term storage, wrap individual brownies tightly in plastic wrap and then in aluminum foil. This way, they’ll stay fresh for up to 30 days in the freezer. When you’re ready to enjoy them, simply reheat each brownie in the microwave for about 10-15 seconds to restore that gooey texture.

What should I do if my brownies are too cakey or dry?
If your brownies turn out too cakey or dry, it could be due to overmixing the batter or baking them too long. Make sure you beat the egg and sugar mixture until pale and fluffy but avoid overmixing once you add the dry ingredients. Always check for doneness at the 45-minute mark; they should come out with just a few moist crumbs for that ideal fudgy consistency.

Is there a way to make these brownies vegan?
Yes! You can easily make these marshmallow brownies vegan by substituting aquafaba (the liquid from canned chickpeas) for the eggs. Use coconut oil instead of unsalted butter and ensure your marshmallow fluff is vegan-friendly. You’ll still get that delicious fudginess without any animal products!

Are marshmallow brownies safe for pets or individuals with allergies?
It’s important to note that marshmallow brownies contain chocolate, which is toxic to dogs and other pets. Also, consider the ingredients used—like eggs and dairy—which may not be suitable for individuals with certain allergies. Always check ingredient labels and consult with a doctor if you’re unsure!
