This wonderful recipe comes from a friend whose had it for many years. It is just delicious. Excellent dessert to take to a pot luck.

Blue Ribbon Recipe

This peanut butter cake is worth doing an extra 30 minutes of cardio... totally a cheat-worthy dessert. The cake's tender and almost has a chewy brownie texture. The cake alone is great, but the frosting is rich and decadent. It firms up a bit and makes the dessert. Bring this to a party and watch it disappear.
