Step‑by‑Step Instructions for Marshmallow Crispy Cookies

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup. This step sets the stage for baking the delicious marshmallow crispy cookies that will soon fill your kitchen with enticing aromas.

Step 2: Brown the Butter
In a medium saucepan over medium heat, add the salted butter and allow it to melt slowly. Continue stirring until the butter turns golden brown and emits a nutty aroma, which should take about 5–7 minutes. Once browned, remove it from the heat and let it cool briefly; for quicker cooling, pop it into the fridge for a few minutes.

Step 3: Mix Sugars and Egg
In a mixing bowl, pour the cooled browned butter. Add both brown sugar and granulated sugar, mixing vigorously until smooth and creamy. Next, crack in the room-temperature egg and drizzle in the vanilla extract, blending these wet ingredients together until fully combined. This mixture will create a sweet base for your marshmallow crispy cookies.

Step 4: Combine Dry Ingredients
Gradually whisk together the baking soda, salt, and all-purpose flour in a separate bowl. Slowly add this dry mix to the wet ingredients in your mixing bowl, stirring gently until just combined. Be careful not to overmix, as we want those marshmallow crispy cookies to remain soft and chewy, rather than dense.

Step 5: Add Crunchy Elements
It’s time to fold in the Rice Krispies and mini marshmallows! Using a spatula, gently combine the crispy cereal and marshmallows with your dough until they are evenly distributed. This will give each cookie that perfect balance of crunch and chewiness, integral to the charm of marshmallow crispy cookies.

Step 6: Portion the Dough
Scoop out large mounds of dough, roughly 3 tablespoons each, and place them onto the prepared baking sheet, allowing enough space between each ball to accommodate spreading. This spacing is essential for those beautifully shaped cookies that won’t merge together while baking.

Step 7: Bake to Perfection
Slide the baking sheet into your preheated oven and bake for 10–13 minutes. Keep a close eye on them; you want the edges to turn light golden brown, while the centers remain soft and chewy. Avoid overbaking to preserve that lovely texture, essential to your marshmallow crispy cookies.

Step 8: Cool and Finish
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. This allows them to set before transferring them to a wire rack to cool completely. Just before serving, sprinkle with flaked salt for an extra burst of flavor, enhancing the sweetness of your delightful marshmallow crispy cookies.

How to Store and Freeze Marshmallow Crispy Cookies

Room Temperature: Store cookies in an airtight container for up to 3 days to keep them fresh and chewy; adding a slice of bread can help maintain moisture.

Fridge: If you prefer, you can refrigerate them for up to a week, but be aware that this may change the texture slightly, making them a bit firmer.

Freezer: For longer storage, freeze the baked cookies in an airtight container for 2-3 months. Thaw them at room temperature and enjoy the chewy, buttery goodness once again!

Dough Freezing: Prepare the cookie dough and freeze it in individual balls for up to 2-3 months, allowing for quick baking whenever you crave homemade marshmallow crispy cookies.

Expert Tips for Marshmallow Crispy Cookies

Brown Butter Mastery: Ensure you continuously stir the butter as it browns to avoid burning. The nutty aroma is key to elevating your marshmallow crispy cookies.
Dough Consistency Check: If your dough feels too sticky, gradually add a bit more flour until it holds together well. This will prevent flat, spread-out cookies.
Watch the Bake Time: Keep an eye on your cookies during baking. They should be golden at the edges and just set in the center for that chewy texture.
Cooling Period: Don’t skip the cooling step! Letting the cookies settle on the baking sheet for a few minutes will help maintain their shape and prevent breakage.
Perfect Portioning: Use a large cookie scoop for uniform size. This ensures even baking, giving your marshmallow crispy cookies that appealing look and texture.

Marshmallow Crispy Cookies Recipe FAQs

How do I choose the right butter for these cookies?
Absolutely! For this recipe, I recommend using salted butter to enhance the flavor, especially when browned. If you prefer unsalted butter, just be sure to add a pinch of salt to maintain the balance. When browning, look for a golden color and a nutty aroma—this richness elevates the overall flavor of your marshmallow crispy cookies!

What’s the best way to store these cookies?
You can keep your cookies fresh by storing them in an airtight container at room temperature for about 3 days. To maintain their soft, chewy texture, consider placing a slice of bread in the container—this helps keep the cookies moist. Alternatively, if you’d like them to last longer, refrigerate for up to a week, but be aware that this may make them a little firmer.

Can I freeze these cookies? How?
Yes! You can freeze your marshmallow crispy cookies in an airtight container for 2-3 months. First, ensure they are completely cool. Place parchment paper between layers if stacking to prevent sticking. When you’re ready to enjoy, simply thaw them at room temperature or pop them into a warm oven for a few minutes. The warmth will revive their chewy goodness!

What should I do if the dough is too sticky?
If you find your cookie dough is too sticky to handle, don’t worry! Just gradually add a bit more flour, approximately 1 tablespoon at a time, until it reaches a manageable consistency. This adjustment will help you shape perfect cookie balls and ensure they don’t spread too much during baking.

Are there any ingredient substitutions I can make for dietary restrictions?
Absolutely! For those needing gluten-free options, feel free to swap the all-purpose flour with a gluten-free 1:1 flour blend and use gluten-free Rice Krispies. If you’re concerned about sugar intake, you can replace brown sugar with coconut sugar or a sugar alternative, though this may affect the cookie’s texture and flavor slightly. Always consider your ingredients to ensure everyone can enjoy these delicious treats!

What can I do if my cookies spread too thin?
If your cookies spread thin while baking, it might be due to soft dough. You can chill the dough in the fridge for about 30-60 minutes before scooping and baking. This will help firm it up, preventing excessive spreading and resulting in that delightfully chewy texture you desire!
