Ingredients in these fluffernutter blondies

These blondies are made with everything tasty. They include regular baking ingredients like sugar, butter, vanilla, flour, and eggs, but they also sneak in peanut butter and marshmallow fluff!

Butter: This recipe kicks off with 1.5 sticks of softened butter.
Peanut butter: Next up is ½ cup of natural peanut butter. This ingredient is going to add the most delicious flavor to the blondies!
Brown sugar: Follow the peanut butter with 1 and ¼ cup of brown sugar. You can use light or dark brown sugar.
Eggs: 2 eggs will help the blondies adopt the proper texture while also helping the ingredients form a batter. They can be regular or large eggs.
Vanilla extract: Gotta have vanilla! Use 1 teaspoon vanilla extract.
Flour: Next up is the flour. Use 1.5 cups of your preferred all-purpose flour brand.
Baking powder: Then, add ½ teaspoon of baking powder.
Salt: Add flavor with ½ teaspoon of salt. Salt is a must!
Peanut butter chips: Mix in 1 cup of peanut butter chips for extra delicious flavor!
Marshmallow fluff: 1 cup of marshmallow fluff will be used as an icing.
Drizzle: Last but not least, save ⅓ cup of natural peanut butter for drizzling on top!

If your butter is cold, try the cup trick! Simply fill a glass cup with hot water. Let it sit for a few minutes, and then pour out the water. Place the glass upside down over a standing stick of butter, enclosing the stick inside. Let it sit for about 10 minutes, and the butter will become soft!

First, preheat the oven to 350°F and line an 8x8 pan with parchment paper and nonstick spray.

Then, use a large mixing bowl and a hand mixer to beat together the butter, peanut butter, and brown sugar until smooth.

Mix in the eggs and vanilla. Once creamy, set aside.

Next, use a medium sized mixing bowl and whisk together the flour, baking powder, and salt.

Use a hand mixer to slowly add the dry ingredients to the wet, and mix until everything is incorporated.

Stir in the peanut butter chips. Then, pour the batter into the greased baking dish.

Bake for 30-34 minutes or until a toothpick inserted in the middle comes out clean and the blondies are just starting to turn golden brown on top.

Let cool completely. Once cooled, ice the blondies with the marshmallow fluff and drizzle on the peanut butter.

Cut into 12 pieces. Enjoy!

Recipe Tips

What can I add to this recipe?

You can add anything you'd like! Ideas include chocolate chips, crushed pretzels, sprinkles, or even chopped chocolate candies.

Can I use regular sugar instead?

White sugar and brown sugar have different consistencies, and using them interchangeably will result in different textured blondies. If you only have white sugar handy, create brown sugar by adding molasses or maple syrup to it.
