I’ll be honest with you—when I first heard about flourless cookies, I was skeptical. How can you make a proper cookie without flour? But these fudgy chocolate marshmallow beauties proved me completely wrong.
They’re chewy, gooey, and packed with that rich chocolate flavor we all crave, plus they happen to be gluten-free without even trying. The best part? You probably already have everything you need sitting in your pantry right now.
Why You’ll Love these Fudgy Flourless Chocolate Marshmallow Cookies
Because I’m basically obsessed with cookies that taste like pure indulgence but won’t leave me feeling guilty, these fudgy flourless chocolate marshmallow cookies have become my go-to when I want something that feels fancy without the fuss.
They’re naturally gluten-free, which means I can share them with practically everyone. The texture is absolutely perfect—crispy on the outside, chewy in the middle, with those little pockets of melted marshmallow that make each bite feel like a tiny celebration.
Plus, they come together in one bowl with ingredients I usually have on hand. No butter, no flour, no complicated steps.
What Ingredients are in Fudgy Flourless Chocolate Marshmallow Cookies?
These cookies require just a handful of simple ingredients that you probably already have hanging around your kitchen.
- 3 cups powdered sugar
- 2/3 cup cocoa powder
- 1/4 teaspoon salt
- 3-4 egg whites, room temperature
- 2 teaspoons vanilla extract
- 1 cup chocolate chips
- 1/2 cup mini marshmallows (optional)
The key thing to remember is getting those egg whites to room temperature first—cold eggs from the fridge will make your batter way too stiff and stubborn to work with.
How to Make these Fudgy Flourless Chocolate Marshmallow Cookies
Step 1
First things first—crank that oven to 350°F and line your baking sheets with parchment paper.
Don’t skip the spraying part either, because these cookies can be a little clingy when they’re fresh out of the oven.
Step 2: Whisk Together Your Dry Ingredients
Grab a large bowl and whisk together 3 cups of powdered sugar, 2/3 cup cocoa powder, and 1/4 teaspoon salt until everything’s nice and combined.
No lumps allowed in this kitchen, people.
Step 3: Beat in the Egg Whites and Vanilla
Time to add those room temperature egg whites—start with 3, but you might need that fourth one depending on how thick your batter looks.
Pour in 2 teaspoons of vanilla extract and beat everything together until you’ve got a smooth, fudgy batter that’s not too stiff to work with.
Step 4: Fold in the Good Stuff
Gently fold in 1 cup of chocolate chips and 1/2 cup of mini marshmallows if you’re using them.
Think of this as tucking them into a cozy chocolate blanket rather than beating them into submission.
Step 5: Let the Batter Rest
Here’s where patience pays off—let that batter sit for 15 to 30 minutes.
I know it’s torture when you just want to start baking, but this little break helps everything come together beautifully.
Step 6: Scoop and Space Your Cookies
Using a cookie scoop or spoon, drop 2-tablespoon-sized mounds of dough onto your prepared baking sheets.
Give them about 2 inches of breathing room because nobody likes a crowded cookie sheet.
Step 7: Bake Until Perfectly Crackly
Pop those beauties into the oven for 12 minutes, until the tops look all crackly and set.
They might look a little underdone, but trust the process—they’ll continue cooking on that hot pan even after you pull them out.
Step 8: Cool Before Moving
Let them hang out on the baking sheet for a few minutes before transferring to a cooling rack.
These cookies are delicate little souls when they’re warm, so rushing this step is just asking for cookie carnage.
For even better results, consider investing in premium baking dishes that distribute heat more evenly and prevent sticking.
What to Serve with Fudgy Flourless Chocolate Marshmallow Cookies
These decadent cookies are perfect for any time you need a serious chocolate fix, whether that’s an afternoon snack or after-dinner treat.
They’re absolutely divine with a tall glass of cold milk—because honestly, what chocolate cookie isn’t? For something a little more grown-up, try them alongside a steaming mug of coffee or hot chocolate.
If you want to get fancy, serve them with a scoop of vanilla ice cream or a dollop of whipped cream. Fresh berries like strawberries or raspberries add a nice tart contrast to all that chocolate richness, and a sprinkle of sea salt on top takes them to the next level.
Fudgy Flourless Chocolate Marshmallow Cookies Substitutions and Variations
While marshmallows bring that gooey sweetness we all crave, you can absolutely make these cookies your own with some simple swaps and creative twists.
I love switching mini marshmallows for chopped regular ones – they create bigger pockets of gooey goodness.
Want nuts? Toss in pecans or walnuts for crunch.
Dark chocolate chips instead of regular? Perfect for intense chocolate lovers.
You can even try white chocolate chips with dried cranberries for a festive touch.
Feeling adventurous? Add a pinch of espresso powder or sea salt on top.
These substitutions keep the fudgy texture while letting your creativity shine.
Leftovers and Storage for these Fudgy Flourless Chocolate Marshmallow Cookies
Once you’ve mastered all those creative variations, you’ll want to keep your cookies fresh and delicious for as long as possible.
I store mine in an airtight container at room temperature for up to a week. They stay perfectly chewy this way.
For longer storage, I’ll freeze them in freezer bags for up to three months. Just thaw at room temperature when you’re ready to enjoy them again.
Pro tip: I like to separate layers with parchment paper to prevent sticking. Trust me, future you’ll thank present you for this simple step.
