I replaced agave nectar with raw honey instead. I do not like processing procedure of agave and do not like the taste.

Followed the recipe except I added 3/4 pkg Reeses Peanut Butter Chips,topped them with Top Secret P-nut butter frosting and took them to work . Everyone said the same thing "Great frosting but the cake didn't taste very much like p-nut butter" Gave it 2 stars because the cake wasn't bad, just didn't taste like p-nut butter

I made this recipe and poored it into a 9x13 cake pan and baked it for about 25 minutes. I then frosted it with Harley Seashell Princess's top secret peanut butter frosting and it was the most delicious and moist peanut butter cake. My whole family loved it, and my boyfriend who hates to compliment my cooking because he thinks he is the better cook said "I hate to say it but this is the best peanut butter cake I have ever had" so that is a huge compliment coming from him. Excellent cake..anyone who loves peanut butter should try this cake!!
