Ah, the unassuming envelope of onion soup mix. It's more than just for onion soup (or dip). It adds tremendous flavor (and convenience) in all these recipes.

A delicious and fluffy peanut butter frosting made with marshmallow creme, peanut butter, butter, vanilla, salt, powdered sugar, and milk
1 cup marshmallow creme

1/3 cup butter or margarine, softened
1/4 teaspoon vanilla extract
1/4 teaspoon salt
1 1/3 cup confectioners' sugar

A can of cream of mushroom soup can be a real dinner saver. It works great in casseroles and can turn into a sauce or gravy in a pinch.

Wow! I almost had to lick the bowl I made this in. Delicious! Only negative is it did come out slightly runny but that can be corrected just by adding a bit more sugar. I may try substituting honey for part of the confectioners sugar next time and put it on some angel food cake cupcakes.

I have made this frosting twice. The first time I made it as another reviewer said...leaving out the butter. And for the peanut butter I used Honey Roasted peanut butter. It was WONDERFUL! Came out nice and thick so that it stayed on the cake wonderfully. Paired it with a yellow cake and my husband went crazy. Second time i was in a hurry and ACCIDENTALLY added the butter...BIG mistake. It came out super thin and ran off the cake. The taste the second time was NOT good at all. Will be making it again....WITHOUT the butter.

I made this frosting to top chocolate cupcakes, and it was great together. I followed the recipe exactly, and I will do the same next time. I piped it out of a pastry bag because it seemed like that would look prettier than trying to spread it with a knife. It isn't the same texture as regular buttercream, but it has such a wonderful flavor, very peanutty, and not too sweet, that it is worth a try.

Put this on top of 16 to 20 chocolate cupcakes, and you will be in heaven! I piped it on with a frosting bag (parchment triangle, so I could have less clean up) and it was messy, but soooo worth it. With a tall glass of cold milk, a cupcake with this frosting will take you back to your childhood. I bet it would be great on yellow cake, too.

I left out the butter, so that it wouldn't be greasy since peanut butter already has a lot of oil. A little sweet, but overall a good frosting.

This frosting has a wonderful taste. Light, not too sweet. The reason I gave it four instead of five stars is because it's a little greasy, even with adding more powdered sugar. The next time I make it, I may leave out the butter and just cream the marshmallow cream and peanut butter together. But I would definitely recommend it!

This recipe is a winner. It's a light peanut butter fluffy taste and easy to make. It's exactly as the name describes. My friends loved this icing and I'm sure I'll have a request to make this again.

This really is the perfect peanut butter frosting! You could not ask for anything more. Try it!

This frosting is the best peanut butter frosting I have ever tasted - I would recommend it to everyone, it is so good!

This is by far the best peanut butter icing recipe I have tried so far. The fluffernutter makes it sweeter tasting then recipes without it, which makes it taste more like actual cake icing as opposed to a mouthful of peanut butter. I would totally recommend this recipe to anyone that absolutely loves peanut butter! I iced a chocolate cake with it and it was the best tasting cake I've ever made!
