I loved this recipe. It is a favorite of almost everyone. thank you for your post.
I loved this filling, I added crushed reese cups inbetween 2 layers of filling. Everyone loved this cake! Thank-you for recipe
do you think this would hold up as icing under a thin layer of fondant?
Everybody I know loves this recipe. I use it for all me chocolate cakes. The best!!
This recipe is GREAT! It makes a lot of filling. It was so good though that I kept baking cakes and cupcakes until I ran out. My family, neighbors, and co-workers loved it!
This is still my most requested Peanut Butter filling. Thank you so much for sharing! It is also really yummy inbetween a banana cake with a simple chocolate ganache poured over the top!
Does anybody know how long this lasts (kept in the fridge)?
Horale! Props to you for this SWEET treat! I used it for my PB cupcakes and for my PB rosette cookies as a topping! THis was Delicioso!
Just used it as a filling in my cupcakes for work.....wonderful. I had difficulties with the whipping cream, I think it was too hot in the house, substituted it with cool whip (small container) and it was wonderful.
A+++++ This filling is fabulous - I am new to cake decorating/baking, but this is the best filling recipe I have tried! The filling doesn't 'get lost in the cake' like the pudding mixtures I've played with before - it's thick enough to truly seperate the layers but still light and fluffy! The peanut butter taste is there, but not overwhelming. Best of all - it's so EASY to make compared with similar recipes I've seen on other websites: no freezing, etc. Love it!! Thanks again!
Great recipe! Used this filling with my standard chocolate cake. Everyone loved it!
This is so good!! I used this as a filling in a chocolate cake and plan to use it for my own birthday cake this year :) I had quite a bit leftover, so I actually froze the leftovers and then pulled out a container, folded in some Cool Whip and poured into an Oreo pie crust for a peanut butter pie - that was fantastic as well!
This was sooooooo good!! I made a peanut butter cake used this and raspberry butter cream, tasted heavenly!!
This recipe sounds really yummy! I'm going to try it this weekend! Can anyone tell me how much it makes? I'm just doing a simple 2-layer, 8" round. Should I halve the recipe?
After not receiving any responses to my lat post I decided to try half of the recipe. Boy am I glad I did! I still have a lot left over! Half of the recipe made about 3 cups for me. Having said that, it is soooo good! :) It is rich, and goes perfectly with chocolate cake. Very good and I will make it again!
Have to say thanks for this recipe, I get requests for this more than any other flavor! I pair it with a dark choc fudge cake~ AMAZING!! It does make alot, although my husband doesn't mind, I usually have to throw him out of the kitchen (with his spoon in hand!) Thanks again!
omg...having leftover cake scraps around with this is quite dangerous! lol It's delicious!!! I am making a Christmas Yule Log - choc fudge cake filled with this mousse and covered with dark choc ganache...(she is a choc and peanut butter addict). She will LOVE this mousse!! Thank you so much!
Omg this is possibly the most fantastic thing ever... I'm pretty sure I went cross-eyed and o-faced eating this! LOL I think I will add a little more PB next time though - I tasted mostly the cream cheese (which is NEVER a bad thing though, I just wanted a bit stronger PB taste!)
I just found this recipe and it sounds wonderful!! I'm going to make cupcakes with strawberry jelly filling so, they'll be 'peanut butter and jelly cupcakes'!! Thank you Melody25 for such an awesome recipe!
I got round to making it this weekend.  I halved the recipe and still had some left.  The halved recipe was more than enough to fill a 20 cm round cake (4 layered cake) and still have a bit left over.  Thank you for sharing, all peanut butter lovers really enjoyed it.
