Ingredients You’ll Need for Fluffernutter Cookies

Here’s everything you need to create these cozy delights, broken down into manageable sections to make your shopping and preparation easier.

Essentials

  • 1/2 cup creamy peanut butter: The star ingredient that brings rich flavor and chewy texture.
  • 1/2 cup unsalted butter, room temperature: This is essential for a soft and creamy cookie dough.
  • 1 cup light brown sugar, packed: Adds sweetness and a lovely caramel undertone to the cookies.
  • 1 large egg, room temperature: This helps bind the ingredients together.
  • 1 teaspoon vanilla extract: For that warm, comforting aroma and taste.
  • 1 1/2 cups all-purpose flour: The base of your cookie dough, providing structure.
  • 1 teaspoon cornstarch: This is great for achieving that tender, soft cookie texture.
  • 1/2 teaspoon kosher salt: Enhances the sweetness of the cookies.
  • 1 cup marshmallow fluff or marshmallow crème: The gooey filling that defines these delightful treats.

Optional Add-Ons

If you want to elevate your Fluffernutter Cookies even further, consider adding:

  • Chocolate chips: A handful of semi-sweet or dark chocolate chips stirred into the dough can take these cookies to a different level of indulgence.
  • Chopped nuts: If you enjoy a bit of crunch, some chopped peanuts or walnuts could provide a lovely contrast to the soft marshmallow.
  • Sprinkles: For a festive touch, especially if you’re baking for a special occasion, colorful sprinkles can make these cookies pop.

Substitutions and Shortcuts

  • Peanut butter alternatives: If you have a nut allergy, sunflower seed butter or soy nut butter work well as a substitute for peanut butter.
  • Butter alternatives: Coconut oil or vegan butter can replace unsalted butter for a dairy-free option.
  • Flour alternatives: For a gluten-free version, use a 1-to-1 gluten-free flour blend, ensuring it contains xanthan gum for proper structure.

How to Make Fluffernutter Cookies Step-by-Step

Let’s break down the process into straightforward steps that ensure your cookies turn out perfectly every time!

  1. Preheat your oven: Set your oven to 350 degrees F. While it heats up, line two large baking sheets with parchment paper to prevent your cookies from sticking.


  2. Mix the wet ingredients: In a large bowl, combine the creamy peanut butter, room temperature unsalted butter, and light brown sugar. Using a hand mixer, mix them together until the mixture is smooth and creamy, which should take about 2-3 minutes. Remember to scrape down the sides of the bowl to incorporate all the ingredients.


  3. Incorporate the egg and vanilla: Add in the large egg and the teaspoon of vanilla extract, mixing until everything is well combined. This should take about 30 seconds—just enough time to enjoy the wonderful scent of vanilla.


  4. Combine the dry ingredients: To the bowl, add the all-purpose flour, cornstarch, and kosher salt. With your mixer on low, gradually mix until just combined. You want to be careful not to overmix here, as it can lead to tough cookies.


  5. Shape the cookies: Use a 2-tablespoon cookie scoop to drop the dough onto your lined baking sheets. Once you have your dough balls, gently flatten each one into a disk about 3 inches across with your hands.


  6. Add marshmallow fluff: Using two spoons, place about 1 tablespoon of marshmallow fluff in the center of each disk.


  7. Seal the fluff: Bring the dough edges up around the marshmallow fluff and pinch it closed, making sure the fluff is completely covered and forming a ball. It’s okay if the cookie doesn’t look perfect; it will spread during baking.


  8. Bake: Place the balls on the baking sheets, spacing them about 2 inches apart, and bake for 10-12 minutes. They should be lightly golden at the edges.


  9. Let them rest: Once out of the oven, allow the cookies to rest on the baking sheets for 10-15 minutes before transferring them to a wire rack to cool completely. This step helps them set up nicely.


Common Mistakes to Avoid

Baking is a wonderful adventure, but it can be easy to stumble along the way. Here are some common pitfalls and how to steer clear of them for your Fluffernutter Cookies.

Mistake 1: Using cold ingredients

Starting with cold butter or eggs can lead to a dense cookie. Make sure your butter is at room temperature, and your egg has also warmed up a bit before mixing.

Mistake 2: Overmixing the dough

While it’s tempting to keep blending until everything is perfectly smooth, overmixing can make the cookies tough. Mix just until the dry ingredients are incorporated.

Mistake 3: Not cooling before decorating

If you attempt to move or decorate the cookies too soon after baking, they might fall apart. Let them rest for the recommended time so they can set properly.
