Fluffernutter Cookie Ingredients
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 large egg
- 1 teaspoon baking soda
- 1/2 cup marshmallow fluff, plus more as needed
Each ingredient plays a crucial role: the peanut butter offers richness and depth, the marshmallow fluff adds gooey sweetness, and the simple pantry staples keep this recipe reliably easy and accessible .
How to Make Fluffernutter Cookies
- Step 1: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to avoid sticking.
- Step 2: In a large mixing bowl, thoroughly stir together the peanut butter and sugar.
- Step 3: Add the egg and baking soda. Mix until a smooth, thick dough forms.
- Step 4: Take a spoonful of dough and flatten it slightly. Drop a dollop of marshmallow fluff in the center, then wrap the dough around it to enclose.
- Step 5: Set each prepared cookie on the baking sheet, spacing them apart. Slightly flatten each cookie to encourage spread.
- Step 6: Bake for 8–10 minutes, watching carefully. The cookies should be lightly golden and puffed, but still soft in the center.
- Step 7: Let cool on the baking sheet—these cookies are delicate when hot! Enjoy the messy, gooey pleasure once cooled.
For best results, keep your hands slightly damp when shaping dough to minimize sticking. You can refrigerate dough briefly for firmer, rounder cookies.
Tips and Tricks for Fluffernutter Cookie Success
- Dough is sticky: Wet your hands lightly while handling dough to prevent sticking .
- Flat cookies: These are naturally large and flat, but chilling the dough before baking produces thicker, chewier results.
- Messiness: Embrace the delicious messiness—Fluffernutter cookies are meant to be gooey and fun.
- Storage: Store cooled cookies in an airtight container. They remain soft for several days.
- Ingredient swaps: Vanilla extract can replace warm spices. Sprinkle cookies with coconut for traditional Scandinavian flair .
Creative Fluffernutter Cookie Variations
- Spiced Fluffernutter Cookies: Add cinnamon, nutmeg, or ginger for a holiday-inspired twist.
- Sandwich Cookies: Cool cookies, then sandwich with an extra spoonful of marshmallow fluff for double the treat.
- Chocolate-Dipped Fluffernutter: After cooling, dip cookies halfway in melted chocolate thinned with neutral oil for a crisp shell .
- Coconut-Coated Fluffernutters: Roll freshly dipped cookies in unsweetened coconut for extra texture and a nod to traditional “mums-mums” treats.
