    Harley Seashell Princess's Note:

    Adapted from a Hershey's recipe, this heavenly concoction starts on the stove-top and ends with countless rave reviews. It has made me famous amongst co-workers and friends! I usually pair it with a buttery Betty Crocker cake mix and then top it off with chocolate curls or drizzled chocolate syrup which has been cut through for a marbled effect.

      The secret to the success of this recipe is to first cook the milk and flour to a paste and then let it cool thoroughly. Don't worry about bringing it to a boil, because it won't. And DO NOT add the sugar to the milk! When the mixture is completely cool, beat the remaining ingredients (sugar, peanut butter, margarine and vanilla) in a bowl until fluffy--the sugar will "dissolve" during the process and will not remain grainy. Then gradually beat in the milk/flour mixture until it is incorporated and the frosting becomes fluffy. (I have already substituted butter-flavored shortening for the margarine and it turns out beautifully.) The consistency of this frosting is more like a firm whipped topping, not like a traditional powdered sugar icing. I have a similar recipe that omits the peanut butter and increases the margarine to 1 cup total. Enjoy!

      Oh my goodness! This is exactly the peanut butter frosting I've been looking for! Made it for
      the frosting for a wacky cake (Wacky Cake) and if I had my way, I wouldn't have shared
      at all. Makes enough for a 9" x 13" cake but I used it all on a 9" x9" inch cake. (no complaints from anyone) Light in texture, full of flavor~will be making this again...and again. Thank you!

      The taste of this peanut butter frosting is D-E-L-I-C-I-O-U-S. I followed doobtones #2 's advice regarding the milk / flour mixture, cooked it on low for about 10 mins stirring constantly. I waited the 30 mins for the mixture to cool on the counter (with the bowl covered in plastic wrap), then separately mixed together the sugar, peanut butter, and I Can't Believe It's Not Butter. I added the milk / flour mixture gradually and mixed thoroughly. The frosting was so smooth and creamy, but very thin. I put it in the fridge overnight hoping it would thicken. It did, but very slightly. I still am not able to spread the frosting on my Chocolate Chocolate Chip Sour Cream Banana cupcakes without it dripping everywhere. I love the taste so much of this frosting that I don't want to add the 8 oz. of cream cheese to it and alter the taste. Does anyone have any suggestions of what else I can do to thicken up the frosting? I was thinking of adding a couple tablespoons of cool whip. Please let me know!!
