    About Peanut Butter Frosting Recipe

    Have you ever made a frosting that requires no mixing bowl, no hand beater, no machine and no tons of icing sugar. Yes, this is that kind of frosting. Made with only a handful of ingredients, sauce pan and a whisk.

    Forget all the peanut butter frosting that you have made so far. This is made with only peanut butter, butter, icing sugar, vanilla and milk. This one will be your new favourite. Yes it is a viewer favourite too. Because this is what " Paulette" says in the comment.

    I made this frosting in a small sauce pan and mixed using a whisk. The frosting starts by melting peanut butter and butter until it is liquidy. Then you add the powdered sugar little at a time and mix.

    The frosting comes together in the same sauce pan in which you melted the butter. You can use this frosting to spread over cupcakes, cakes or even cookies. They stay fudgy and thick. I used this to frost my eggless vanilla cake.

    Ingredients

    • Unsalted Butter - I used unsalted butter, since the peanut butter already has salt added. You can use salted butter too.
    • Peanut Butter - I used crunchy peanut butter since i need my frosting to have bits of peanuts for texture. You can use smooth peanut butter. You can use homemade peanut butter.
    • Confectioners Sugar - also known as icing sugar, powdered sugar is used for making the frosting. If your powdered sugar is slightly lumpy, sieve it before adding for smooth frosting.
    • Vanilla Extract - a small bit of vanilla enhance the taste and flavour of the frosting.
    • Milk - don't add too much, you just need a spoon of milk.

    Step by Step pictures

    4)The peanut butter till melt as well. The mixture will get slightly liquidy.

    5)Take it off the heat and add in vanilla extract and mix well. Set aside to cool a bit before adding the sugar.

    6)Now add in confectioners sugar. Add little at a time and mix well using a whisk.

    7)Once the first addition is mixed well, you can add more.

    8)Add more confectioners sugar. Totally I used around 1 cup. Sometimes you might need to add more.

    9)Now you can see the mixture is slightly too thick.

    10)I added 1 spoon of milk and whisked again.

    11)As you mix, the frosting will get glossy in texture and shiny. Like fudge frosting.

    12)Thats it your peanut butter fudge frosting is ready to use.

    13)I used this frosting to frost my eggless vanilla cake.

    14)Look how fudgy the frosting looks like.

    15)This frosting goes well with vanilla or chocolate flavoured cakes.

      I would love to try this recipe on my next chocolate sheet cake, but I'm not sure I want to use it if it's "orangy." Orange and peanut butter doesn't sound appealing to me. I didn't see anything in the ingredients that would add an orange flavor. Did I miss something?
