You can never go wrong with Peanut Butter & Marshmallow! Simple enough, slightly tedious, but worth every second of it!
Ingredients:
Preheat Oven to 350F
Grease a 9×13 inch pan with nonstick cooking spray
– 3/4 Cup of Unsalted Butter, Melted (1.5 Sticks)
– 1 Cup of Brown Sugar
– 1/2 Cup of Sugar
– 2 Eggs
– 2 Tsp of Vanilla Extracts
– 3/4 Cup of Creamy Peanut Butter
– 1/2 Tsp of Salt
– 1 1/2 Cups of All Purpose Flour
Frosting:
– 1/2 Cup of Unsalted Butter, Melted ( 1 Stick )
– 7 Ounces of Marshmallow Fluff ( They sell 7 oz Containers of it)
– 2 Cups of Powdered Sugars
Optional:
– 1/2 Cup of Peanuts, Chopped or Crushed
Use Chopped if you want them inside the Cake or Crushed for a garnish on top of the Frosting.
I chose the crushed nuts, to pick and choose which pieces to garnish. Joys of children, they never all want anything the same way.
Melt the 1 1/2 sticks of butter, pour into a large Mixing Bowl.
Using a hand-blender, mix together the butter, brown sugar, and regular sugar in the large mixing bowl.
Blend in your eggs and vanilla extract thoroughly.
Optional: Add in your 1/2 Cup of Chopped Nuts
Now add in the peanut butter and blend until mixed in.
In a separate mixing bowl, mix together the salt and flour.
Gradually add in the flour mixture, mixing as you add in small increments.
Keep adding and mixing until you’ve combined it all together.
Evenly pour and spread out your new mixture into your 9×13 inch baking dish.
Baking for 25 – 30 minutes, 25 minutes is usually perfect in my oven.
After 25 minutes, remove from oven. If you have a Toothpick, you should be able to poke it into the center and remove without having any mixture left on the it. 
Melt the other stick of butter.
Combine your Melted Butter and Marshmallow Fluff, beating together until mixed.
Add your Powdered Sugar, 1 cup at a time, beating thoroughly together each time.
Pour your Marshmallow Frosting over your cake, spreading evenly.
Optional: If you chose crushed nuts, you can choose to top the entire cake with them now or garnish each piece individually as you serve it.
These came out delicious!
Definitely a messy one for younger children, but they all completely loved their pieces!
