Fluffernutter Cookies Instructions

Making Fluffernutter Cookies is just as fun as eating them! Follow these steps to create your own batch of chewy, delicious cookies. You’ll soon be embracing the sweet aroma wafting from your kitchen.
- Start by placing butter and both types of sugar into the bowl of a stand mixer fitted with the paddle attachment. Alternatively, you can use a large mixing bowl and a handheld electric mixer. Beat on medium-high speed until the mixture is well combined and creamy, about 2 minutes. The mixture should be light in color and fluffy.
- Next, stop the mixer and scrape down the sides of the bowl. Add the egg and vanilla to the bowl. Beat until the mixture is light and fluffy, which should take about 5 minutes. You’ll notice that it becomes pale and airy.
- Now it’s time to add the dry ingredients. Into the bowl, sift in the flour, salt, baking powder, and baking soda. Beat on low speed until just combined, taking care not to overmix. This step should only take about 1 minute, and the dough will still look a little shaggy.
- Next, gently fold in the cereal, marshmallows, and peanut butter chips. Beat briefly, just until all the ingredients are incorporated, which should take around 15 seconds. You want to see pockets of peanut butter and marshmallows throughout the dough.
- Using a 2-tablespoon cookie scoop or your hands, form approximately 25 to 30 equal-sized mounds of dough. Roll each mound into a ball and then flatten them a little less than halfway. This helps them bake evenly.
- Place the mounds of dough on a large plate or tray, cover with plastic wrap, and refrigerate them for at least 2 hours, or up to 3 days. This chilling step is crucial as it prevents the cookies from spreading too much during baking.
- When you’re ready to bake, preheat your oven to 350°F (175°C). Line a baking sheet with a Silpat or spray it with cooking spray to prevent sticking.
- Arrange the chilled dough mounds on the prepared baking sheet, spaced at least 2 inches apart. Do not crowd them, as they will spread. Optionally, press an additional marshmallow or two on top of each cookie along with some extra peanut butter chips for a fun touch.
- Bake for about 9 to 10 minutes. Keep an eye on them; the cookies are done when the edges have set and the tops are just set, even if they appear slightly undercooked and glossy in the center. Remember, they will firm up as they cool.
- Finally, allow the cookies to cool on the baking sheet before enjoying them. Resist the urge to use a cooling rack – letting them cool on the baking sheet helps maintain that perfect chewy texture.
Things Worth Knowing
- Chill Your Dough: Chilling the dough prevents cookies from spreading excessively. This will help maintain the desired texture.
- Watch the Bake Time: Since ovens can vary, keep an eye on the cookies as they bake. Overbaking can lead to hard cookies.
- Use Quality Ingredients: Using high-quality peanut butter and fresh marshmallows makes a noticeable difference in flavor.
- Experiment with Mix-Ins: Feel free to add nuts, chocolate chips, or even a sprinkle of sea salt for added depth of flavor!
