Common Questions

How long do I let fudge sit?

This microwave peanut butter fudge recipe just requires about one hour in the fridge to harden before you serve it. 

Can I add toppings to this 2 ingredient peanut butter fudge recipe?

You certainly could! For example, some sprinkles could add a really fun pop of color! 

Can I make this fudge with any frosting? 

I avoid making my peanut butter fudge recipe with either cream cheese or whipped frostings. The fudge just doesn’t taste the same with those kinds of canned icing.

You can pretty much use any brand of frosting though so feel free to use whatever one you like or have on hand!

How do I double this easy PB fudge recipe? 

This recipe is super simple. It’s a 1-to-1 ratio of peanut butter and icing. So however much icing you want to use, just use that much peanut butter to balance it out.

If you want to simply double the recipe you’ll need to use 32 oz of peanut butter and 32 oz of icing. 

2 Ingredient peanut butter fudge only takes 2 minutes to make.

Storage suggestions

The best way to keep fudge fresh for as long as possible is to keep it in an airtight container at room temperature. This will help to prevent the fudge from drying out before you’re finished with it.

My daughter made this fudge but she used strawberry icing and the peanutbutter. It is amazing it tastes like a peanutbutter an strawberry sandwich. Just a perfect switch from regular peanutbutter fudge..

Has anyone tried this using peanut butter & butterscotch frosting? Just wondering if these two flavors mix well together?

The absolute best and easiest fudge recipe. I made 6 batches to hand out ar xmas and I've used 3 different types of frostings: chocolate, vanilla and butter cream and they all turned out great. Today I used chunky PB, vanilla frosting and whipped in some chocolate chips. Yum
