Step‑by‑Step Instructions for Marshmallow Crispy Cookies

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This preparation will create a non-stick surface for your baking, making it easier to remove those delicious Marshmallow Crispy Cookies once they are baked.

Step 2: Brown the Butter
In a medium saucepan over medium heat, melt ½ cup of salted butter, stirring continuously. Keep an eye on the butter as it melts; it should turn a rich, golden brown, emitting a nutty aroma. This process takes about 5-7 minutes. Once browned, let it cool in the fridge for about 10 minutes to prevent curdling when mixed with other ingredients.

Step 3: Mix the Sugars and Wet Ingredients
In a large mixing bowl, combine the cooled browned butter, ¾ cup of brown sugar, and ½ cup of granulated sugar. Use a hand mixer or wooden spoon to mix until the sugars are well integrated with the butter, creating a smooth and creamy consistency. Next, add one large room-temperature egg and 1 teaspoon of vanilla extract, mixing until fully blended.

Step 4: Combine Dry Ingredients
Gradually sift in 1 ½ cups of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of salt into the wet mixture. Stir gently with a spatula or wooden spoon, being careful not to overmix. The dough should come together beautifully but remain slightly thick, retaining a rich, buttery aroma that hints at the crispy goodness to come.

Step 5: Fold in Rice Krispies and Marshmallows
Now, gently fold in 2 cups of Rice Krispie cereal and 1 cup of mini marshmallows into the dough. Ensure that the add-ins are evenly distributed without losing their shape. The mixture will be slightly sticky and chunky, filled with sweet marshmallows ready to transform into the delightful Marshmallow Crispy Cookies.

Step 6: Scoop the Dough
Using a 3-tablespoon cookie scoop, form dough balls and place 4-5 on the prepared baking sheet, ensuring an even distance between them. The dough will spread during baking, so leave enough room for each cookie to expand without merging into one another.

Step 7: Bake the Cookies
Slide the baking sheet into the preheated oven and bake the cookies for 10-13 minutes. Keep an eye on them; the edges should turn a light golden brown while the centers look set yet slightly soft. Avoid overbaking to maintain a chewy texture reminiscent of those beloved Marshmallow Crispy Cookies.

Step 8: Finish and Cool
Once baked, remove the cookies from the oven and immediately sprinkle a pinch of flaked salt on top of each cookie for a delightful contrast to the sweetness. Allow them to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely. Enjoy your freshly baked treats!

Marshmallow Crispy Cookies Recipe FAQs

What type of butter should I use for the best flavor?
Absolutely! Using salted butter enhances the richness in your Marshmallow Crispy Cookies, but feel free to use unsalted butter if you’re watching your sodium intake. The choice impacts flavor slightly, with the salted version complementing the sweetness wonderfully!

How long can I store these cookies?
You can store the cookies in an airtight container at room temperature for up to 3 days. If you’d prefer to keep them longer, refrigerate them for up to 5 days, but be sure to allow them to return to room temperature for the best texture.

Can I freeze the dough for later use?
Yes, indeed! To freeze the dough, scoop the cookie balls onto a baking sheet lined with parchment paper and freeze them until firm. Once frozen, transfer the dough balls to an airtight container or a labeled freezer bag. They can be stored in the freezer for up to 3 months. Bake them directly from the freezer—just add an extra minute or two to the baking time!

What should I do if my cookies spread too much?
If you find that your cookies are spreading excessively, you can refrigerate the dough for about 1 hour before baking. This step helps firm up the fats in the dough, leading to thicker cookies. Additionally, consider adding an extra 2 tablespoons of flour to the mixture, which can help achieve a more desired texture.

Can these cookies cater to gluten intolerance?
Very much so! You can easily make gluten-free Marshmallow Crispy Cookies by substituting all-purpose flour with a gluten-free 1:1 flour blend. This way, everyone can enjoy the tasty treats without any worry about gluten allergies.

Are there any alternative mix-ins I can use?
