Grease and line a 20cm square (8") pan with butter or cooking spray and parchment paper and set aside.
400 g smooth peanut butter, 400 g vanilla frosting (I used Betty Crockers)
Put the peanut butter and frosting together in a bowl and mix to combine. The texture will get firmer as you mix, with the texture of the fudge resembling play dough (Play-Doh) when it's ready.
Press the fudge mixture into a greased and lined pan, flatten with a silicone spatula to smooth the top and place in the refrigerator to set.

Notes
Honestly, this fudge can be eaten pretty much straight away as soon as it's combined. You will literally see it firm up as you mix it. The texture gets a little firmer in the refrigerator.
I found smooth peanut butter works best for this recipe rather than the crunchy kind.
The size of the container you put the fudge in can vary from what I have used, it will just turn out thicker or thinner. A baking pan or a loaf pan are both good ideas, plus you could also use a plastic container to set it in too.
Greasing and lining the pan with parchment paper is still important for this recipe even though it's a no bake dessert. This will help you get the fudge out of the pan or baking dish once it's set.
I recommend lining your pan with parchment or baking paper because it's stronger than foil and less likely to tear when you lift it out.
