Ingredients

- 1 cup unsalted butter, softened
Unsalted butter adds richness and moisture to the cookies, ensuring a soft texture. Soften it before use to help it cream better with the sugar. - 1 cup creamy peanut butter
Peanut butter is the star ingredient, contributing flavor and a unique texture. Its fat content aids in creating a chewy cookie. - 1 cup granulated sugar
This adds sweetness and plays a crucial role in helping cookies spread and achieve the right texture. - 1 cup brown sugar, packed
Brown sugar introduces a caramel-like flavor and additional moisture, leading to chewy cookies with depth. - 2 large eggs
Eggs act as a binder, providing structure and lift to the cookies while also contributing to their richness. - 2 ½ cups all-purpose flour
Flour is essential for the structure of the cookies, ensuring they hold their shape and have a good bite. - 1 tsp baking soda
Baking soda is a leavening agent that helps the cookies rise slightly, providing a tender crumb. - 1 tsp vanilla extract
Vanilla enhances the overall flavor profile of the cookies, adding warmth and depth. - ½ cup mini marshmallows
Mini marshmallows embed pockets of gooey sweetness within the cookies, enhancing the fluffernutter experience.
Directions & Preparation
Step 1: Preheat the oven to 350°F (175°C).
Preheating the oven is crucial for even baking. A properly heated oven ensures that the cookies spread perfectly and develop a nice golden color.
Step 2: In a large mixing bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until the mixture is light and fluffy.
Creaming these fats and sugars together incorporates air, which helps the cookies rise and remain soft. This foundation determines the cookies’ overall texture.
Step 3: Add in the eggs, one at a time, followed by the vanilla extract. Mix until well combined.
Incorporating the eggs one at a time ensures that they are fully integrated into the mixture, enhancing the dough’s emulsion and richness.
Step 4: In a separate bowl, whisk together the flour and baking soda. Gradually add this dry mixture to the wet ingredients, mixing until just combined.
Whisking the flour and baking soda separately helps distribute the baking soda evenly throughout the flour, promoting an even rise in the cookies.
Step 5: Gently fold in the mini marshmallows until evenly distributed throughout the dough.
Folding helps keep the marshmallows intact while ensuring they are spread throughout. Adding them at this stage also ensures they melt slightly during baking, resulting in gooey pockets.
Step 6: Drop heaping tablespoons of dough onto parchment-lined baking sheets, spacing them about 2 inches apart.
Spacing is essential as the cookies will spread while baking. Parchment paper prevents sticking and promotes even browning.
Step 7: Bake in the preheated oven for 10-12 minutes or until the cookies are just golden around the edges.
Baking them until just golden gives the cookies a soft center. Avoid overbaking to maintain that desirable chewy texture.
Step 8: Remove from the oven, and after a few minutes, transfer the cookies to a wire rack to cool completely.
Cooling the cookies on a wire rack prevents them from steaming on the baking sheet, which could make them soggy. It also helps set their structure.
The Perfect Balance of Sweet and Savory
Fluffernutter Butter Cookies uniquely blend the distinct sweetness of sugars with the savory depth of peanut butter, creating a well-rounded flavor profile. The marshmallows introduce a light, airy sweetness, preventing the cookie from being overly rich. Each bite presents an intricate balance that awakens the taste buds, making it hard to stop at just one.
A Gooey Surprise in Every Bite
One of the standout features of these cookies is the delightful surprise of melty marshmallows nestled within. As they bake, the marshmallows soften and create little pockets of gooey sweetness. This unexpected enjoyment enhances the flavor and elevates the overall experience of eating the cookie, making it a hit for those who love a bit of indulgence.
Versatile for Any Occasion
Fluffernutter Butter Cookies are not just a simple treat; they are incredibly versatile. Perfect for lunchboxes, birthday parties, or cozy family gatherings, their appealing taste and soft texture cater to various occasions. You can even tailor them by adding chocolate chips or other mix-ins to suit your flavor preferences, making them a delightful option for any cookie lover.
FAQs
What can I do if my cookie dough seems too thick?
If your cookie dough is too thick, try adding a tablespoon of milk or water to loosen it up. This should help achieve the desired consistency for scooping.

Can I substitute the peanut butter with almond or cashew butter?
Yes, you can use almond or cashew butter instead of peanut butter. Just keep in mind that the flavor and texture may slightly differ.
How can I ensure my cookies don’t spread too much?
Chilling the dough for about 30 minutes before baking can help prevent excessive spreading, resulting in thicker cookies.
What should I do if my cookies are overcooked?
If your cookies are overcooked, ensure to reduce the baking time next time. Look for a light golden edge and a soft center.
