peanut butter is always my weakness! Haha!! It’s so wonderful in baked goods.
Yum! I love Peanut Butter!
Who put the yummy peanut butter cake after the workout videos?
Bless you for making a dessert that doesn’t have chocolate in it as I am allergic to it.
Throw in some raw wheat germ or oats or use whole wheat flour and you add a little healthy to it. Makes a great breakfast cake. One of my favorites.
Just had to come back to tell you. My husband ask where I got the recipe for this cake. When I told him about your blog he told me to tell y’all thank you. So.. from my peanut butter lovin’ husband(and his wife) a great big THANK YOU!!! The only change I made was Crunchy peanut butter instead of smooth. This is a keeper, and I am sharing it with my family. Thank you again.
Hello gals!

Have a fabulous Sunday!
