Brown Butter Marshmallow Cookies Ingredients
For the Cookie Dough
• Unsalted Butter – Provides richness and flavor; consider using salted butter but reduce additional salt.

• All-Purpose Flour – Gives the cookies structure; remember to spoon and level to avoid dense cookies.
• Baking Soda – Essential for a fluffy rise.
• Salt – Balances sweetness and enhances flavors; no substitutions recommended unless using salted butter.
• Eggs – Binds the ingredients and adds moisture, crucial for that perfect texture.
• Marshmallows – Provide the iconic gooey pull; mini marshmallows ensure even distribution throughout the cookies.
Optional Add-ins

Step‑by‑Step Instructions for Brown Butter Marshmallow Cookies
Step 1: Brown the Butter
To begin making your Brown Butter Marshmallow Cookies, melt 1 cup of unsalted butter in a medium saucepan over medium heat. Stir constantly as the butter bubbles and foams, watching for it to turn a rich golden brown, about 5-7 minutes, releasing a nutty aroma. Once browned, remove it from heat and let it cool for a few minutes.
Step 2: Mix Sugars
In a large mixing bowl, combine the cooled brown butter with 1 cup of brown sugar and ½ cup of granulated sugar. Using a hand mixer or a whisk, blend the mixture until it becomes creamy and smooth, which should take about 2-3 minutes. The sugars help to infuse sweetness and create that rich base essential for your cookies.
Step 3: Add Eggs
Now, beat in 2 large eggs, one at a time, ensuring each egg is fully incorporated before adding the next. This process is crucial for binding the ingredients and achieving that perfect chewy texture in your Brown Butter Marshmallow Cookies. After combining, stir in 1 teaspoon of vanilla extract for an extra layer of flavor.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 2 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the cookies tender; the dough should be slightly thick and sticky, perfect for folding in the marshmallows.
Step 5: Fold in Marshmallows
Gently fold in 2 cups of mini marshmallows into the cookie dough, ensuring they are evenly distributed for that gooey surprise in each bite. Take your time with this step to keep the marshmallows intact, avoiding any crushing. You’ll notice the dough is now a delightful mix of sweet and soft textures, ready for chilling.
Step 6: Chill Dough
Cover the bowl with plastic wrap or transfer the dough onto a baking sheet lined with parchment paper, and refrigerate for at least 30 minutes. Chilling the dough allows it to firm up, making it easier to scoop and helping the cookies hold their shape while baking.
Step 7: Bake
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper. Use a cookie scoop or spoon to drop mounds of dough onto the prepared sheets, leaving space between each. Bake for 10-12 minutes, or until the edges are golden brown and the centers look just set, with a beautiful pull from the gooey marshmallows.
Step 8: Cool
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. This allows them to firm up slightly. Afterward, transfer the cookies to a wire rack to cool completely, ensuring they retain their chewy texture and marshmallow goodness. Enjoy your homemade Brown Butter Marshmallow Cookies fresh or store them for later!

Brown Butter Marshmallow Cookies Recipe FAQs
How do I choose the right marshmallows?
Absolutely! For these cookies, I recommend using mini marshmallows as they distribute evenly throughout the dough. Regular marshmallows can also work, but they might create larger gooey pockets, which some may find too intense. Look for marshmallows that are fresh and soft; anything with hard or dry exteriors may not melt properly.
How should I store my cookies?
The more the merrier! Store your Brown Butter Marshmallow Cookies in an airtight container at room temperature for up to one week. If you’d like to keep them extra soft, add a slice of bread inside the container. This trick helps maintain their chewiness. For longer storage, refrigerate them for up to a week, but let them come to room temperature before enjoying.
Can I freeze these cookies?
Certainly! You can freeze your Brown Butter Marshmallow Cookies for up to 3 months. First, place the cookies in a single layer on a baking sheet to freeze. Once fully frozen, transfer them to a sealed freezer bag or container. This method prevents them from sticking together. When you’re ready to enjoy, just pop them in the microwave for 10-15 seconds or warm them in a preheated oven at 350°F (175°C) for a few minutes.
What if my cookies spread too much while baking?
Very good question! If you find your cookies spreading too much, it could be due to warm dough or not enough flour. Make sure your dough is chilled for at least 30 minutes before baking; this helps them hold their shape. If the dough feels too soft, you can also add a tablespoon more flour to help firm it up.
Are there any allergy concerns with this recipe?
Absolutely! This recipe contains common allergens such as dairy (butter, eggs) and gluten (flour). For those with egg allergies, a flaxseed egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let sit for 5 minutes) can be used as a substitute. Just keep in mind that it may slightly alter the texture. Always check labels on store-bought ingredients to be certain!
