How to Make Fluffernutter Cookies
Making fluffernutter cookies is a simple and rewarding process. Start by mixing together your dry ingredients to ensure an even texture. Then, blend your creamy peanut butter and butter until they’re perfectly smooth. The addition of sugars will create a glossy mix, adding to the cookies’ delightful sweetness.
After adding the egg and vanilla, you’ll gently incorporate the dry ingredients until just combined. The fun begins with shaping the cookie dough, where you’ll create a deliciously hidden pocket of marshmallow fluff. After rolling them in sugar for a bit of extra sweetness, these cookies bake to golden perfection, ready to fill your home with a cozy aroma.
Ingredients
To make fluffernutter cookies, gather these items:
1 3/4 cup All-Purpose Flour
1 tsp Baking Soda
1/2 tsp Salt
1/2 cup Creamy Peanut Butter
1/2 cup Unsalted Butter (room temperature)
1/2 cup Granulated Sugar (plus additional 1/4 cup for coating the cookies)
1/2 cup Light Brown Sugar
1 Large Egg
1 tsp Vanilla Extract
1 cup Marshmallow Fluff
Feel free to substitute creamy peanut butter with crunchy if you prefer a bit of texture, or adjust the sugar ratio based on your sweetness preference.
Directions
- Adjust your oven rack to the second level mark (just above center), preheat your oven to 350ºF, and line 2 baking sheets with parchment paper. Set them to the side.
- Whisk together the all-purpose flour, baking soda, and salt in a small bowl. Set aside.
- In a mixing bowl, beat together the peanut butter and unsalted butter until blended; the mixture should be creamy.
- Add in the granulated sugar and light brown sugar, mixing until well blended and glossy.
- Add the egg and vanilla extract, mixing until fully combined.
- Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Using a cookie scoop, place balls of cookie dough onto the parchment. Flatten each ball slightly.
- Place a dollop of marshmallow fluff in the center of each dough disc and fold the sides over to cover the fluff, reshaping them into balls.
- Roll the cookie balls in granulated sugar, then place them back on the baking sheet.
- Bake for 10-12 minutes until golden around the edges. Let cool on the sheet for 5-10 minutes before transferring to a cooling rack.
- Store in an airtight container at room temperature for up to 5 days or freeze for up to 3 months.
How to Serve Fluffernutter Cookies
To truly enjoy these fluffernutter cookies, consider pairing them with a glass of cold milk or a warm cup of hot cocoa for a comforting treat. For an added twist, try serving them with a scoop of vanilla ice cream on the side for a delightful sundae experience. Kids love to enjoy these cookies crumbled over a bowl of ice cream or even on top of a warm slice of chocolate cake.
How to Store
Fluffernutter cookies can be stored in an airtight container at room temperature for up to 5 days, making them perfect for snacking. If you find yourself with leftovers, they also freeze beautifully. Simply place them in a freezer-safe container, where they’ll stay fresh for up to 3 months. When you’re ready to enjoy them again, just let them thaw at room temperature.
Tips to Make
One easy tip to elevate your fluffernutter cookies is to slightly underbake them for a chewy texture. If you prefer a stronger peanut butter flavor, you can use natural peanut butter instead of the creamy variety. For an extra touch, consider sprinkling a bit of sea salt on top of each cookie right after they come out of the oven for a sweet and salty balance.
Variations
There are plenty of fun ways to switch up fluffernutter cookies! Try mixing in some chocolate chips or butterscotch chips to introduce a new layer of sweetness. For a festive twist, consider using seasonal sprinkles or swapping in seasonal flavors like pumpkin spice for fall. If you’re looking for a healthier option, you could experiment with almond butter for a different taste profile.
