All you need to make peanut butter fudge are three basic ingredients.   Peanut butter, butter and confectioner’s sugar. Adding vanilla extract is optional.

How to Make Microwave Peanut Butter Fudge

  • In a microwaveable bowl, mix peanut butter and butter. Cook the mixture in the microwave for one minute. Then, stir the mixture and microwave for another minute. 
  • Stir until fully incorporated. Add powdered sugar and mix until smooth. You’ll know it’s done when you see a thick, paste-like batter.
  • Place the batter into a baking pan lined with parchment paper. Place a sheet of parchment paper on top of the fudge and start pressing with your palms to spread evenly across the pan. 
  • Refrigerate for at least 2 hours. Remove the fudge from the pan and cut into small squares using a sharp knife. And that’s it. Easy-breezy, right?

Should Peanut Butter Fudge Be Refrigerated?

Once your family takes a bite of this peanut butter fudge, it’s unlikely there will be any leftovers. In fact, I recommend making extra to enjoy later. 

There’s no need to refrigerate, unless you like your fudge cold. Store your fudge in an air-tight container and it will stay fresh for 3 to 5 days.

If you refrigerate your fudge, it will last for up to a month and up to 1 year in the freezer.

How Long Does Fudge Last?

The shelf-life of fudge depends on how you store it. At room temperature, fudge will last for two weeks. If you refrigerate it, it’s good for a month. If you freeze it, it can survive for an entire year!

Just don’t place it inside the freezer door. Store your fudge at the back to shield it from shifts in temperature whenever someone opens the freezer.

But, before eating stored fudge, it’s also wise to check for signs of spoilage. When you start to see cracks on your fudge, that means it’s been exposed to too much air. This makes your fudge dry and less tasty.

Likewise, when your fudge becomes way too soft and mushy, it means it’s time to let it go. Also, if the fudge has become tough and has an oily surface, it’s also past its prime.

How To Store Microwave Peanut Butter Fudge

There are 3 main ways to store fudge: at room temperature, in the fridge, or in the freezer. Here are some quick guidelines to follow depending on the method you choose. 

  • If you’re storing fudge at room temperature, there is no need to wrap it in plastic wrap or foil. Rather, place it in a plastic container or a self-sealing bag. 
  • It’s best to store fudge in a cool, dark area in the house. Do not place it on the countertop, or anywhere near a heat source.
  • If you’re going to refrigerate fudge, place it in an air-tight container. Cold air will make your fudge dry, so do not expose it to air when storing. 
  • Do not place the fudge squares too close together, either, as it will cause them to stick to each other.
  • If you freeze your fudge, double-wrap (first with wax paper, then with plastic wrap or aluminum foil) the squares individually beforehand. This will make it easy for you to thaw out one slice at a time. Then, place the squares into an air-tight container or a  zip lock freezer bag. To thaw, simply place in the fridge or on the counter for a few hours.

Tips For the Best Fudge

While peanut butter fudge is meant to have a smooth consistency, others prefer a little bit of crunch. A great way to give your fudge a crunchy twist is to add peanuts to the batter right before spreading it onto a baking sheet. Yum!

  • Before cutting the fudge into squares, make score lines to ensure even squares. I like to use dental floss to score my fudge – the unflavored kind, of course.
  • You’re free to choose however big or small you want your squares to be, but keep in mind that it’s better to make small squares (about an inch) if you’re giving them out as gifts. The smaller the size, the more squares you get!
  • Use a kitchen ruler to make sure you get uniform-sized squares.
  • Before cutting, heat your knife under hot water and dry with a towel.
  • If your fudge starts to get too moist, simply take it out of the container and unwrap. Fudge naturally starts to dry when exposed to air. Leave unwrapped for a few hours and it will become much firmer.

Health Benefits Of Peanut Butter

In this article we list down the health benefits of peanut butter covering nutrients and minerals like Protein, Fiber, Folate, Vitamins like B1 and B6 (Thiamin and Pyridoxine). Peanut butter is not just a physically healthy and nutritious food, it’s also mentally healthy. Let’s check out the health benefits of peanut butter and the reasons why you should start eating more peanut butter.

Apart from its great taste, peanut butter may have vital nutrients that are essential for the body. The health benefits of this tasty butter include the following:

1. Can be a Rich Source of Protein

Peanut butter (100 grams) may contain a high amount of protein (25 – 30 grams). Proteins that we eat are broken down into amino acids, which are then utilized in every cell for repairing and building the body

2. May Lower Cholesterol Levels

A 2016 research paper published in the Journal of Food Science and Technology has revealed that peanuts can be an excellent source of compounds like resveratrol, phenolic acids, flavonoids, and phytosterols that completely stop the absorption of cholesterol from the diet. Probably, the fat content in peanut butter is almost equal to that of the fats found in olive oil. It contains both polyunsaturated fats and monounsaturated fats. As these fats are not saturated, they are good to consume without putting the heart at any risk. The unsaturated fats in peanut butter can help to lower bad cholesterol levels (low-density lipoprotein) and may promote the circulation of good cholesterol (high-density lipoprotein). 

3. May Prevent Type 2 Diabetes

Consuming peanut butter can also be beneficial in reducing the risk of type 2 diabetes. Peanuts contain not only protein but also unsaturated fats. Unsaturated fats may have been noted to improve insulin sensitivity. Research into peanut butter consumption and diabetes showed that a higher intake of peanut butter and other nuts can lower the risk of type 2 diabetes.

4. Can be a Good Source of Vitamins

Peanut butter contains many vitamins that are can be good for our body to function properly. Vitamin A found in it can be helpful for eyesight, while vitamin C may help to boost the immune system and heals simple ulcers faster. On the other hand, vitamin E found in peanut butter can be a very important micronutrient needed by our body to dissolve complex fatty acid structures and fat blockages in the arteries

5. Potentially Antioxidant Properties

Peanut butter may contain antioxidant properties due to the presence of folate, niacin, pantothenic acid, pyridoxine, riboflavin, and thiamin. One of the antioxidants found in it is resveratrol. Resveratrol is a polyphenolic antioxidant that may help in controlling chronic diseases. 

6. May Regulate Blood Sugar Levels

Peanut butter is a good source of magnesium (170mg/100 grams). This makes up 42% of the daily recommended value of magnesium. Magnesium has an important role to play in muscle, bone, and immunity development in the body. Magnesium can also help in regulating blood sugar levels and blood pressure. Its presence in our body may help in probably more than 300 biochemical reactions that are extremely important for our survival. 

7. Possibly High in Potassium

Peanut butter contains potassium (70 mg/100g) that may act as an electrolyte and is a fluid-balancing element in the body. In comparison to sodium, which directly puts pressure on the cardiovascular system in the form of hypertension, potassium does not put any pressure either on the blood or on the cardiovascular system. In effect, potassium is a heart-friendly element that is found in possibly high quantities in peanut butter. 

8. May Reduce Risk of Gallstones

Gallstones, a major health risk in developed countries, is caused by being overweight, crash diets, certain types of cholesterol drugs, and birth control pills. A study published in the American Journal of Clinical Nutrition on peanuts and nut consumption relating to the risk of gallstones was undertaken and the results of the study showed that over a period of 2 decades, women who consumed peanut butter and nuts regularly may have reduced their risk of developing gallstones.
