Is this an easy fudge recipe?

First things first: this is a super simple and easy peanut butter fudge. It requires just 2 ingredients.

I don’t like difficult recipes in general. I’m not interested in spending all my time in the kitchen. I’m interested in spending time with family and friends sharing meals and desserts that were easy to make. That is where this delicious peanut butter fudge recipe comes in; though it doesn’t last long…everyone loves it!

You will use one small jar of any brand of peanut butter and one container of flavored frosting. Stir the two ingredients together and microwave. Stir until completely mixed. Pour into pan and refrigerate for at least six hours. Cut and enjoy. Full printable recipe at the end of this post.

Weight Watchers information for peanut butter and icing fudge 

For the new Personal Points program, we expect this recipe is between 7 – 12 points per serving. It’s going to differ for each person based on your needs and goals. It’s a new plan that focuses on different values and points for each person!

If you use an 8 x 8 glass pan you can get 25 servings of fudge that are 1.5 inches by 1.5 inches. Fudge is a rich sweet treat so a tiny piece will go a long way. Each piece would be 7 points on all three WW plans.

That’s why we do Weight Watchers so we can choose what to eat, when, and how much. If you have the points and want to eat some fudge it’s your choice. Plus, if you make this to take and share at a gathering, they’ll be none left to take home. Trust me.

Can I make this fudge with any frosting? 

I avoid making my peanut butter fudge recipe with either the 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!

Have you tried making chocolate peanut butter fudge with just 2 ingredients? 

I have used chocolate icing in the past, but I really prefer the plain old vanilla. I wouldn’t say that it tastes bad it just not my favorite. It’s certainly possible to make chocolate peanut butter fudge with frosting and peanut butter like this! 

I have been told by others that the cream cheese frosting tastes just fine to them too, so it’s probably my dislike for cream cheese in general that makes me think that the taste is odd.

Can I use flavored frosting to make this 2 ingredient peanut butter fudge? 

You definitely can! Feel free to experiment with different flavors and tastes. Last fall we tried the maple bacon frosting with peanut butter and it was definitely a favorite around the dessert table.

I personally have never tried to make this kind of microwave peanut butter fudge with sugar-free icing varieties…that doesn’t mean it can’t be done 🙂 I’ve had readers try it and say that it works okay. If you are watching your sugar intake you can certainly give it a try. I would think the only difference might be the time it takes to firm up.

Need a quick gift for the holidays? 

This fudge is a perfect Christmas or any time of the year gift. I look forward to sharing it with the mail lady, Sunday school teachers, co-workers and anyone who drops in for a visit. Christmas is all about giving.

Even if you don’t have a lot of money to buy for others a special homemade treat is sure to warm someone’s heart.

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

What kitchen tools do I need when making this homemade fudge? 

When I mix up this treat, I always have a rubber spatula close by. You’d be surprised at how many extra servings you can scrape from a peanut butter jar or icing container with just a few swipes of a spatula. I’d have to say that the rubber spatula is one kitchen gadget I could not live without.

What size pan do I use to make your peanut butter fudge recipe? 

My fudge is normally made in a 9 x 9 glass pan. I prefer one with a lid for easy storage and transport. I keep my fudge in the refrigerator. The glass pan lets me see what’s inside and is a perfect size for a nice thick piece of fudge.

Does 2 ingredient fudge with frosting and peanut butter to set up? 

Yes! So it’s really easy to make, but it still requires some time to firm up. Once you are done mixing the ingredients they’ll need to go back into the fridge to cool down and set up. I find this is another area the glass pan really helps, the glass will more evenly cool everything down and speed the process up a bit. 

Do you have any other dessert recipes I can try? 

Here’s an easy chocolate fudge recipe that only has 3 ingredients. I’m also very fond of these pumpkin bars, this sticky toffee pudding, and these brownies! 

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.

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

Well I just made this with the vanilla frosting and the peanut butter. I have to say I’m very disappointed in the taste. I’ve made this before but I used the cream cheese frosting and it’s always been a hit and the flavor was great. But I was reading this recipe and I saw where it says “avoid using cream cheese frosting”. So I thought I’d give the vanilla a try. Well, never again.They have absolutely no taste , I’m afraid that there won’t be anyone eating these but me. Other than that they turned out great texture wise. Sorry for the negative comment.

Sorry to hear this. I feel the same way about the cream cheese icing.I think it tastes horrible. I have never had anyone that i have served complain about the taste. It should taste more like peanut butter than anything. Thanks!
