I made this because Little_wing makes the best recipes. It was fantastic! I used milk instead of buttermilk because I didn't have buttermilk. I also used a whole pk. of peanut butter cups mini. I just threw in, next time I will chopped them up a bit. Thanks for a great recipe!
I made this for my mom's birthday cake and it was a HUGE hit! Everyone just loved it! I didn't have buttermilk, and used reg milk, it was still a perfect cake. My daughter loved decorating it with left over peanut butter cups.
