Making These Nutty & Sweet Cookies

• Cookie Foundation

A delightful blend of soft dough packed with rich peanut butter flavor, creating a perfect base for our sweet creation.

• Dough Preparation

Cream together creamy butter, nutty peanut spread, and sugars until the mixture becomes light and airy. Add egg and vanilla for extra depth of flavor.

• Chilling Time

Let the dough rest in the refrigerator, allowing ingredients to meld and develop a more intense taste profile.

• Cookie Shaping

Gently roll small balls of dough onto baking sheets, creating little dimples in the center for marshmallow nestling.

• Marshmallow Magic

Pull cookies from the oven midway and strategically place fluffy white marshmallows into the cookie centers. Return to oven for a quick melt.

• Chocolate Drizzle

Create a silky chocolate glaze by carefully melting chocolate with a touch of butter. Gracefully drip the glossy mixture over cooled cookies.

• Final Touch

Allow chocolate to set slightly, transforming these treats into a decadent dessert that combines classic childhood flavors of peanut butter, marshmallow, and chocolate.

Add-Ins for Fluffernutter Cookies

• Baking Brilliance: Tips to Elevate Your Fluffernutter Cookies
• Chill for Success: Refrigerate the dough for up to 24 hours to intensify flavors and prevent spread during baking. Cold dough creates perfectly shaped, bakery-style cookies with crisp edges and soft centers.
• Marshmallow Magic: For extra gooey texture, use fresh mini marshmallows and watch them carefully while melting. Remove cookies from the oven just as marshmallows start to puff and turn golden for the perfect sweet swirl.
• Peanut Butter Perfection: Choose creamy, no-stir peanut butter for the smoothest cookie consistency. Natural peanut butter can make dough too oily, so stick with classic smooth varieties for best results.
• Chocolate Drizzle Trick: Warm chocolate glaze slightly before drizzling to create beautiful, smooth lines. Use a spoon or piping bag for elegant, professional-looking finish that adds extra decadence to each cookie.
• Storage Wisdom: Store cookies in an airtight container at room temperature for up to 3 days. Layer between parchment paper to prevent sticking and maintain their soft, chewy texture.

Serving the Cookies While They’re Soft

• Sweet Sandwich Sidekick: Pair these delightful Fluffernutter cookies with a cold glass of milk for the ultimate nostalgic dessert experience that brings back childhood memories.
• Picnic Perfect Treat: Pack these cookies in a cute container for outdoor gatherings, potlucks, or school lunches where they'll be the star attraction among sweet lovers.
• Dessert Platter Delight: Arrange the cookies on a beautiful serving plate with a sprinkle of powdered sugar, creating an elegant presentation that makes the treats look even more irresistible.
• Coffee Companion: Serve these cookies alongside a warm cup of coffee or hot chocolate, allowing the rich peanut butter and marshmallow flavors to complement the beverage's warmth and depth.

How to Store Fluffernutter Cookies

• Delightful Storage Solutions
• – Airtight Container Magic: Nestle cooled cookies in a sealed container, separating layers with parchment paper to maintain their perfect texture and prevent sticking. Keep at room temperature for 3-4 days of deliciousness.
• – Freezer-Friendly Trick: Wrap individual cookies or the entire batch in plastic wrap, then place in a freezer-safe bag. These treats will stay fresh for up to 2 months, ready to thaw and enjoy whenever sweet cravings strike.
• – Marshmallow Maintenance: Store cookies away from direct sunlight and humidity to keep marshmallow tops soft and gooey. Avoid refrigerating, as this can make the cookies lose their tender texture.
• – Make-Ahead Brilliance: Prepare cookie dough up to 3 days in advance and refrigerate. When ready to bake, let the dough sit at room temperature for 15 minutes to soften slightly before shaping and baking.
