Step‑by‑Step Instructions for Marshmallow Crispy Cookies Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). While the oven heats up, line a baking sheet with parchment paper for easy cookie release later. This preparation step is crucial as it ensures an even bake, helping your Marshmallow Crispy Cookies achieve that perfect golden-brown hue. Step 2: Brown the Butter In a medium saucepan over medium heat, add the salted butter and gently stir it as it melts. Keep stirring continuously until it turns a beautiful golden brown and emits a nutty aroma, about 5-7 minutes. Once browned, remove it from heat and allow it to cool for about 10 minutes before mixing with other ingredients. Step 3: Mix Sugars and Egg In a large mixing bowl, combine the cooled browned butter with both brown and granulated sugars. Use a whisk or electric mixer to blend until the mixture is smooth and combined. Next, crack in the room temperature egg and add the vanilla extract, stirring until everything is fully incorporated and silky. Step 4: Combine Dry Ingredients Gradually add the baking soda, salt, and all-purpose flour to the wet ingredients. Mix gently with a spatula or wooden spoon, taking care not to over-mix. The goal is a soft dough; stop mixing as soon as you see no more flour streaks. This step is crucial for the texture of your Marshmallow Crispy Cookies. Step 5: Fold in Rice Krispies and Marshmallows Now, it’s time to fold in the rice krispies and mini marshmallows. Gently incorporate these ingredients into your dough with a spatula, ensuring that the marshmallows and crispy cereal are evenly distributed. This will enhance the delightful texture of your cookies, combining chewiness with crunch. Step 6: Portion the Dough Using a cookie scoop or spoon, scoop out large balls of dough, approximately 3 tablespoons each. Place them onto the prepared baking sheet, ensuring there’s ample space between each cookie to allow for spreading during baking. This step helps your Marshmallow Crispy Cookies maintain their shape while baking. Step 7: Bake the Cookies Slide the baking sheet into the preheated oven and bake your cookies for 10-13 minutes. Watch for the edges to turn lightly golden while the centers remain soft and chewy. Avoid overbaking, as this could alter the delightful texture we aim for in these delicious Marshmallow Crispy Cookies. Step 8: Finish with Flaked Salt As soon as you remove the baking sheet from the oven, sprinkle the freshly baked cookies with a touch of flaked salt. This adds a wonderful contrast to the sweetness and elevates the flavor profile. Allow the Marshmallow Crispy Cookies to cool on the sheet for a few minutes before transferring them to a wire rack to cool completely. Expert Tips for Perfect Marshmallow Crispy Cookies Butter Browning: Make sure to stir continuously while browning the butter; it can go from perfect to burnt quickly, ruining the flavor. Dough Thickness: For cookies with a thicker texture, add 2 extra tablespoons of flour or chill the dough for 30 minutes before baking to maintain shape. Measuring Flour: Aerate your flour by fluffing it with a spoon before spooning it into the measuring cup. This prevents packing, resulting in lighter cookies. Avoid Spreading: If your cookies spread too much, chill the dough for 20-30 minutes before scooping and placing them on the baking sheet. Fresh Ingredients: Ensure your baking soda is fresh for the best rise. Expired ingredients can lead to flat cookies that aren’t as enjoyable. Customization: Feel free to switch mini marshmallows for chocolate chips, introducing a new flavor profile while retaining the essential nature of these Marshmallow Crispy Cookies. How to Store and Freeze Marshmallow Crispy Cookies Room Temperature: Store your cookies in an airtight container at room temperature for up to 2-3 days to keep them fresh and chewy. Fridge: If you want to extend their freshness, you can refrigerate them in an airtight container for about a week. Just remember to bring them back to room temperature before enjoying! Freezer: For longer storage, freeze the cookies for up to 2-3 months. Be sure to wrap them individually in plastic wrap and place in a freezer bag to prevent freezer burn. Cookie Dough: You can also freeze the cookie dough in balls. Just bake them straight from the freezer when the craving strikes; add a minute or two to the baking time for perfectly fresh Marshmallow Crispy Cookies! Make Ahead Options These delicious Marshmallow Crispy Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by following the recipe up to the portioning step. After scooping the dough into balls, simply place them in an airtight container and refrigerate. This allows the flavors to meld beautifully while preventing the cookies from spreading too much during baking. When you’re ready to enjoy, just bake the chilled cookie dough balls for an extra minute or so until golden brown. This method ensures that your cookies remain just as delightful and fresh, saving you precious time on busy days!

Marshmallow Crispy Cookies Recipe FAQs What kind of butter should I use for these cookies? You can use salted butter for a rich flavor, or unsalted butter if you prefer to control the saltiness. If you choose unsalted, just add a pinch of salt to the mix for balance. How should I store my Marshmallow Crispy Cookies? Store your cookies in an airtight container at room temperature for 2-3 days. If you want to keep them fresh longer, refrigerate them for up to a week. Before enjoying, let them return to room temperature for the best texture. Can I freeze these cookies for later? Absolutely! You can freeze them for up to 2-3 months. Wrap each cookie individually in plastic wrap and place them in a freezer bag to prevent freezer burn. To enjoy them straight from the freezer, bake them from frozen by adding an extra minute or two to your baking time. What can I do if my cookies spread too much while baking? If your cookies spread too much, it’s likely due to the dough being too warm or too soft. To avoid this, chill your dough for at least 20-30 minutes before scooping and baking. This will help maintain their shape and result in a thicker cookie. Are there any allergy considerations for these cookies? Yes, be mindful that these cookies contain common allergens like wheat (from flour) and eggs.
