Quick and easy two layer fudge

I found this amazing recipe in a Facebook post, and I'm sharing it here. I apologize for not being able to credit the original author.

My family devoured this dish within hours of preparation.

I divided a 40-ounce jar of peanut butter into two bowls.

I used one 16-ounce (regular size) Hershey chocolate cake frosting and one 16-ounce cream cheese cake frosting. You may use your preferred frosting flavors.

I melted the first bowl of peanut butter in the microwave for one minute on high, then melted the Hershey cake frosting the same way. I poured the cake frosting into the melted peanut butter and stirred thoroughly. I poured this into a greased 9x4 casserole dish. I popped it into the freezer for roughly twenty minutes. Then I did the exact same thing to the next bowl of peanut butter, adding the melted cream cheese frosting and mixing well. I poured the second layer on top of the first and placed it in the refrigerator for thirty minutes.

If your knife sticks to the fudge, add a little oil to your knife with a paper towel. 

My family and I have agreed that the longer the fudge sets, the better it is. But good luck with that part. Ours didn't last!
