Instructions
1

Preheat the oven to 350℉. Line a 9x9-inch baking pan with parchment paper.
2
|
In a mixing bowl using an electric mixer, cream together the softened butter, brown sugar, and white sugar for 30 seconds. Add the egg and vanilla and continue creaming at high speed until fluffy.

|
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Add to the wet ingredients and continue mixing at low speed just until incorporated. Spread about ⅔ of the mixture into the bottom of the prepared baking pan, smoothing it into an even layer.

Add the marshmallow fluff on top of the batter and spread all around with a greased spatula as best as you can. Lastly, top with dollops of the remaining batter all over on top of the marshmallow fluff. Spread the batter out as best as you can.

Bake the bars in the preheated oven for 25-30 minutes or until lightly golden around the edges and puff up in the center. Let cool slightly before lifting the bars out of the pan using the parchment paper as a handle. Slice and serve. Enjoy!

Tips & Tricks (5)
- Marshmallow Layer Magic 🧈Spray your spatula with non-stick cooking spray before spreading marshmallow fluff to prevent sticky frustration and achieve a smooth, even layer.
- Peanut Butter Precision 🥜Use room temperature peanut butter and butter to ensure easier mixing and a more uniform cookie base that bakes more evenly.
- Pan Preparation Pro 🍳Line your baking pan with parchment paper with overhanging edges for easy removal and clean, perfect bar cuts.
- Moisture Control Technique 💧If your marshmallow layer seems too runny, briefly chill the first cookie layer before adding the fluff to create better structural integrity.
- Cutting Clarity 🔪Use a hot, clean knife wiped with vegetable oil between cuts to get smooth, clean edges when portioning your Fluffernutter Bars.
