Ingredients You’ll Need for Cozy Fluffernutter Bars

1 cup peanut butter
1 cup brown sugar
1/2 cup granulated sugar
1/2 cup unsalted butter, softened
2 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup marshmallow fluff

How to Make Cozy Fluffernutter Bars

Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
In a large bowl, mix together the peanut butter, softened butter, brown sugar, and granulated sugar until creamy and well combined.
Beat in the eggs and vanilla until the mixture is smooth and delightful.
In another bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture into the peanut butter mix, stirring until just combined—a cozy batter begins to form!
Spread half of the batter into the prepared pan, creating a sweet base that will hold all the delights to come.
Spoon the marshmallow fluff over the batter, spreading it gently so it covers every corner—this is the magic layer!
Dollop the remaining batter on top and swirl it gently, like a hug for the fluff.
Bake for 25-30 minutes, or until golden brown—the kitchen should smell heavenly by now.
Let cool completely before cutting into squares. The wait will be worth it!

Fun Ways to Customize It

Nutty Additions: Consider adding chopped nuts like walnuts or peanuts for a delightful crunch and extra flavor.
Chocolate Swirls: Drizzle some melted chocolate over the top for a rich, decadent twist that pairs beautifully with the peanut butter.
Zesty Twist: Add a teaspoon of orange or lemon zest to bring a refreshing citrus note—perfect for summer.
Cookie Crush: Mix in crushed graham crackers or your favorite cookies for a textural element that adds another layer of richness.
