I make a very similar recipe, but I puts insulin in mine. Don't judge.
It's too much peanut butter. The genius of the Resses peanut butter cup is that the chocolate overwhelms the peanut butter, giving it a better taste. But if the peanut butter overwhelms the chocolate, it's gross.
Peanut butter blondies are good, chocolate cheesecake is good, Reese's are good, but peanut butter frosting is always gross. All of this stuff together is just a fucking mess. What a waste of time.
