How to Make Irresistible Fluffernutter Bars: A Sweet, Gooey Dream
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This step ensures that your bars bake evenly and develop that perfect golden color.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, combine the softened butter, peanut butter, and brown sugar. Using an electric mixer or whisk, beat until this mixture is light and fluffy. This step is crucial because creaming incorporates air into your batter, giving your bars that delightful texture.
Step 3: Add Egg and Vanilla
Next, add in the egg and vanilla extract. Mix until fully combined. The egg acts as a binder here; it helps hold everything together while adding moisture.
Step 4: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour. Gradually add this dry mixture into your wet ingredients while mixing until just combined. Be careful not to overmix; we want our bars tender!
Step 5: Fold in Chocolate Treats
Now comes the fun part! Gently fold in the chocolate chips and chopped peanut butter cups. This adds bursts of chocolatey goodness throughout each delicious bite.
Step 6: Create Your Gooey Layer
Spread half of the batter into a greased baking dish. Then dollop on vegan marshmallow creme/fluff evenly across this layer before topping with the remaining batter. Swirling some of it on top gives those beautiful gooey pockets when baked!
Step 7: Bake Away!
Bake in your preheated oven for about 25-30 minutes or until golden brown around the edges but still soft in the center. Remember not to overbake—those gooey textures are what we aim for!
Step 8: Cool & Slice
Allow your bars to cool completely before slicing into squares. Patience is key here; letting them cool will help achieve clean cuts without losing that lovely gooeyness inside.
There you have it—a recipe that’s sure to become a beloved favorite! Enjoy every bite of these Irresistible Fluffernutter Bars: A Sweet, Gooey Dream at home or share them with friends!
Pro Tips for Making Irresistible Fluffernutter Bars: A Sweet, Gooey Dream
