Step-by-Step
Instructions for Easy Fluffernutter BarsFollow these simple steps to make the perfect Easy Fluffernutter Bars:
Prepare the Dough:
- Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or lightly grease it to prevent sticking.
- Mix the Wet Ingredients: In a large mixing bowl, beat the softened butter and peanut butter together until creamy and smooth. Add the granulated sugar, brown sugar, and eggs, mixing well until everything is combined. Stir in the vanilla extract for added flavor.
- Combine the Dry Ingredients: In a separate bowl, sift together the flour, baking powder, and salt to ensure there are no lumps in the dry ingredients.
- Add Dry Ingredients to Wet Ingredients: Gradually fold the dry ingredients into the wet mixture using a spatula or wooden spoon. Be careful not to overmix; just stir until everything is combined and smooth.
Add the Marshmallow Fluff:
- Incorporate the Marshmallow Fluff: Gently fold in the marshmallow fluff until it’s evenly distributed throughout the batter. If you’re adding mini marshmallows for extra texture, gently stir them in now. Be careful not to break the marshmallows apart.
Bake the Fluffernutter Bars:
- Transfer to Pan: Pour the batter into the prepared baking pan and smooth the top with a spatula. Make sure it’s evenly spread out.
- Bake: Bake the bars for 30-35 minutes, or until the top is golden brown, and a toothpick inserted into the center comes out clean or with a few moist crumbs. The bars will firm up as they cool, so don’t worry if they seem a little soft in the middle.
- Cool: Let the bars cool in the pan for 5-10 minutes before transferring them to a wire rack to cool completely.
Cut and Serve:
- Cut into Bars: Once the bars are completely cooled, cut them into squares or rectangles, depending on your preferred size. These bars are perfect for sharing and serving at parties or gatherings.

How to Serve Easy Fluffernutter Bars
Easy Fluffernutter Bars are incredibly versatile and can be served in many ways:
- With Ice Cream: Serve the bars warm with a scoop of vanilla ice cream or whipped cream for an extra indulgent treat.
- With Coffee or Tea: These bars pair wonderfully with your afternoon coffee or tea, making them the perfect snack for a relaxing break.
- For Parties: Serve them on a dessert platter along with other sweet treats like brownies, cookies, or cupcakes for a delicious dessert spread.

Additional Tips for Easy Fluffernutter Bars
Here are some helpful tips to make your Easy Fluffernutter Bars even better:
- Don’t Overmix the Batter: When folding in the dry ingredients, mix gently to keep the bars soft and chewy. Overmixing can lead to a dense texture.
- Test for Doneness: Oven times may vary, so keep an eye on the bars while baking. A toothpick should come out with a few moist crumbs, not wet batter.
- Add a Touch of Salt: For a sweet-and-salty twist, sprinkle a pinch of sea salt on top of the bars before baking.
- Try Different Mix-ins: If you’re feeling adventurous, try adding chocolate chips, chopped nuts, or even a drizzle of chocolate on top for added flavor and texture.
- Chill the Dough: For an even chewier texture, chill the dough for 30 minutes before baking. This can help the bars hold their shape better when they bake.
