This microwave Peanut Butter Fudge is rich, creamy, and delicious! Plus, it calls for just three ingredients and can be made in just 5 minutes. Perfect for your next family get-together.
How to Make 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?
- 8 oz unsalted butter
- 1 cup creamy peanut butter
- 1 pound powdered sugar
1. Line an 8x8 inch pan with parchment paper. Use enough so that the paper hangs over the side. This makes it much easier to remove the fudge from the pan.
2. In a microwave-safe bowl, combine butter and peanut butter. Microwave for 1 minute and stir. Microwave for another minute and stir until mixture is completely smooth and incorporated.
3. Add in the powdered sugar and stir until smooth. You'll know it’s done when you see a thick, paste-like batter.
4. Spread the batter onto the lined baking pan. Place a sheet of parchment paper on top of the fudge and start pressing with your palms to spread evenly across the pan.
5. Refrigerate for at least 2 hours. Remove the fudge from the pan and cut into small, 1-inch squares using a sharp knife.
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 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 & Tricks
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.
Whether you want to give it as a gift, serve it to family and friends, or just want to have it all to yourself, Microwave Peanut Butter Fudge is a heavenly dessert that’s easy to make. Perfect for any occasion.
