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, 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.

This doesn't make fudge. I tried it but still had to run to the store and grab a bag of white chocolate chips in order to get it to 'set up' Anyone who had this same problem this one added ingredient will fix the problem completely. 11 ounce bag of Hershey white chocolate morsels and done!

Sorry to hear that. You must have overcooked. I have been making this exact recipe for 20+ years with no problems.

I wish this page had a link to click that took me directly to the recipe instead of me having to scroll for a year just to find it. Especially when I discovered I tried this recipe before and it turned out like garbage.

I guess you missed the print recipe button right at the top of the page. Oh, you were to busy trying to find things to complain about to see it...

I made a double batch, it turned out perfect. So easy to make. Thank you for the recipe. Do you think if I added some peanut butter whiskey or cinnamon whiskey, it would turn out?

I ran into some peanut butter morsels mixed with chocolate morsels the other day. I thought I'd try them in my 3 ingredient quick fudge recipe. I bought 2 bags because I needed 3 cups of morsels and 1 can of sweetened condensed milk. I put the 3 cups of peanut butter and chocolate morsels in a microwaveable bowl and then put the can of sweetened condensed milk on the morsels. I did give it a brief stir to help get the milk divided more evenly on the morsels. Then I microwaved the mixture 15 seconds and took out and stirred to mix better. Then I put the mixture back into the microwave for 15 seconds and removed it and completely got it mixed thst time. Then I putvit back into the microwave for another 15 seconds to get it melted enough to pour into 9 by 9 inch pan lined with foil. Set in refrigerator overnight and cut into squares the next morning. Tasted more like reese's peanut butter cups. Microwaving the chocolate morsels only 15 seconds at a time will help to keep from getting dry and hard pieces of chocolate
