Indulge in this delectable Peanut Butter Cookie Cake! It is filled with M&Ms, peanut butter chips, and peanuts! The perfect treat for the peanut butter lover in your life!
Preheat the oven to 350 degrees. Line one giant (11") cookie pan with parchment paper, set aside (I usually cut out a large circle for the bottom).
In the bowl of a stand mixer, beat together both sugars, butter and peanut butter until smooth, about 2-3 minutes.
Next, add vanilla, heavy cream and one egg. Mix until incorporated, then add the remaining egg and mix in.
In a separate medium size mixing bowl, whisk together flour, baking soda, baking powder and salt.
Then, add in dry ingredients into the stand mixer bowl, mixing until no visible dry ingredients remain.
Remove the bowl from the stand mixer and gently fold in the M&M's, peanut butter chips and chopped peanuts.
Using a spatula, place the dough into the pan, pressing to create an even layer.
Place the pan in the oven and bake for 15-20 minutes or until the edges become golden brown in color. Remove from the oven and allow to cool for 45 minutes before frosting.
Meanwhile, to prepare the frosting, beat all the frosting ingredients together for 3 minutes or until the mixture becomes light and fluffy.
Finally decorate to your liking, serve, and enjoy!
