Fluffernutter Cookies AKA Peanut Butter Marshmallow Cookies


Fluffernutter Cookies

10 Tips to keep in mind when cooking Fluffernutter Cookies

  1. Use creamy peanut butter: Creamy peanut butter works best for these cookies as it blends smoothly into the dough, providing a rich peanut flavor throughout.

  2. Soften the butter: Make sure to soften the butter before creaming it with the sugars. Softened butter will incorporate more easily into the dough, resulting in a tender texture.

  3. Mix the dough until just combined: Overmixing the dough can lead to tougher cookies. Mix until the ingredients are just incorporated to maintain a soft and chewy texture.

  4. Fold in the marshmallows and peanuts gently: When adding the mini marshmallows and chopped peanuts, fold them into the dough gently to avoid crushing the marshmallows and maintain their shape.

  5. Chill the dough if needed: If the dough becomes too soft to handle or if you prefer thicker cookies, you can chill the dough in the refrigerator for about 30 minutes before baking.

  6. Use a cookie scoop or rounded tablespoon: To ensure evenly sized cookies, use a cookie scoop or a rounded tablespoon to portion out the dough onto the baking sheet.

  7. Leave space between cookies: The cookies will spread as they bake, so be sure to leave about 2 inches of space between each cookie to prevent them from merging together.

  8. Adjust baking time to achieve desired texture: If you prefer softer and chewier cookies, reduce the baking time slightly. For crisper cookies, extend the baking time by a minute or two.

  9. Let the cookies cool on the baking sheet: After removing the cookies from the oven, allow them to cool on the baking sheet for a few minutes. This helps them set and prevents them from breaking apart.

  10. Store properly to maintain freshness: Once cooled, store the cookies in an airtight container at room temperature. Adding a slice of bread to the container can help keep them soft and fresh for longer.

These Peanut Butter Marshmallow Cookies are a delicious treat on their own, but if you'd like to elevate the experience, here are some serving suggestions:

  2. Milkshakes: Blend the cookies with some vanilla ice cream and milk to create a delightful Peanut Butter Marshmallow Cookie milkshake. Top it with whipped cream and a sprinkle of crushed cookies for an extra indulgence.

  3. Peanut Butter Frosting Dip: Whip up a creamy peanut butter frosting to serve as a dipping sauce for the cookies. The sweet and nutty frosting pairs perfectly with the soft and chewy cookies.

  4. Coffee or Hot Chocolate Pairing: Enjoy the cookies alongside a cup of your favorite coffee or hot chocolate for a cozy and comforting treat. The flavors complement each other beautifully.
