DELICIOUS! This recipe deserves nothing less than 5 stars. Naturally you wouldn't expect any kind of peanut butter frosting to spread as pretty as butter cream and still taste like peanut butter, this is "peanut butter" we're talking about after all. My cake tasted fabulous and looked fabulous. It is not anything like a paste, if you follow the recipe correctly, and add milk "as needed" like it says and whip it long enough, its perfect. Major pet peeve....someone leaving a review when clearly they did not follow the recipe like it is written, how can you review this recipe if you didn't follow it? This went in my GOLDEN RECIPE BOOK. Frosted brownies with it, oh la la, Loved it!! Read More

This is 3 stars if you make it as written, which I did. But it was very hard to spread, even on a 9 x 13 sheet cake. I couldn't even imagine trying to frost a layer cake with it like this. So, I decided to chalk that cake up to experience and made another. This time I used a heaping cup of Jif peanut butter (probably around 1 1/4 cups), 1 1/2 cups of powdered sugar and 3 T of heavy cream. I beat the room temperature butter and the room temperature peanut butter for several minutes until I could not see any butter at all in the mixture and it seemed very creamy. Then I gradually added the powdered sugar and when it was well-blended, I added the 3 T of heavy cream and then put it on #6 on my KitchenAid mixer and let it go for 3-4 minutes. This time it was MUCH easier to spread and tastes great!! Read More

Very easy and nice. However, in order to get a good consistency, all ingredients should be at room temperature. If they get too grainy and hard after u added in 3 tablespoons milk, stop adding. Instead, put ur bowl into microwave on high for 30 sec, take out and stir. This will solve the problem. Great frosting. Very peanut buttery! Read More

This frosting is amazing--it balances flavor against sweetness well and the texture was perfect: creamy fluffy not oily at all. I followed the recipe EXACTLY as written no alterations necessary. I made sure my butter was softened (not just room temperature) and I used Jiff's Creamy PB with No Added Sugar; the two whipped together beautifully in about a minute (and I just own a bottom-barrel Black & Decker hand-held mixer); then I added the powdered sugar a half-cup at a time whipping as I went; I made sure to add in 1 Tbl milk between each sugar-addition so that I could judge moisture-spreadability ratio. It kept wonderfully fluffy and spreadable for the hour and a half that I used it then put the remainder in the fridge. It does harden in the fridge but gently microwaving it with a tablespoon or two or milk and then stirring returns it to its original malleability. I liked this recipe so well I made an additional batch substituting Nutella for the peanut butter--it tasted incredible! Read More

Make sure you use butter rather than margarine. I've used margarine before and the icing comes out kind of greasy. Butter will give you beautiful fluffy icing. Also I add 2 tsp of vanilla when I make this. Read More

Great multi-purpose frosting. Worked well for piping too. Had some left over, chilled it rolled it into balls and dipped in melted chocolate. You have to keep them in the fridge but they are incredible. Read More

My sister found a box of chocolate cake mix in Mom's pantry today...and decided she needed cupcakes right then! Of course, she didn't look for frosting when she found the cake mix...so we tried this recipe. Holy cow is it good! And so easy! It made a lot of frosting though...too much for a batch of cupcakes. So, I'll have to make brownies later this week! Yummy! Read More

Oh my gosh as I sit here licking the spatula and swiping my finger into the almost empty bowl thank you thank you thank you for this great recipe. I had no problems spreading the icing or mixing it. Other than making half a recipe which frosted my 13x9 gob cake perfectly I made it exactly as written. Thanks again! Read More
