Ingredients

1/2 cup unsalted butter, cut into cubes
3 1/2 cups powdered sugar, sifted
1 teaspoon pure vanilla extract
1/4 teaspoon salt

Directions

In a large microwave-safe bowl, combine the creamy peanut butter and cubed unsalted butter. Microwave on high power for 1 minute. Stir the mixture well until the butter is fully melted and the peanut butter is smooth. If necessary, microwave for an additional 15 to 30 seconds.

Add the sifted powdered sugar, vanilla extract, and salt to the warm peanut butter mixture. Stir vigorously with a spatula until completely combined. The mixture will be thick and fudge-like. Press the fudge mixture firmly into an 8×8-inch baking dish lined with parchment paper. Smooth the top with a spatula. Refrigerate for at least 1 hour until firm. Cut into small squares and serve.

Variations

For a crunchy texture, use chunky peanut butter instead of creamy. You can also add 1/2 cup of mini marshmallows for a fun, chewy variation. To make it extra festive, sprinkle a pinch of sea salt or some chopped peanuts on top before chilling. Remember, the base of this 5-Minute Microwave Peanut Butter Fudge is incredibly versatile.

Storage and Reheating

Store your 5-Minute Microwave Peanut Butter Fudge in an airtight container in the refrigerator for up to two weeks. It can also be frozen for up to three months.

I do not recommend reheating this fudge, as it is best enjoyed cold or at room temperature.

FAQs

Can I use natural peanut butter for this 5-Minute Microwave Peanut Butter Fudge?

Yes, you can use natural peanut butter, but the texture may be slightly different. Natural peanut butter often separates, so be sure to stir it very well before using. The fudge may be a bit softer and less stable than if you use a standard commercial peanut butter.

Why is my 5-Minute Microwave Peanut Butter Fudge too soft?

If your fudge is too soft, it may not have been chilled long enough. Ensure you refrigerate it for at least 1 hour. Also, check that you used the correct amount of powdered sugar. Sifting the powdered sugar is important to avoid lumps and ensure proper structure. If the mixture is still too soft after chilling, add a little more sifted powdered sugar next time.

Can I make this 5-Minute Microwave Peanut Butter Fudge vegan?

Absolutely. To make a vegan version, use a plant-based butter substitute and ensure your peanut butter is vegan-friendly. Many creamy peanut butters are naturally vegan. The result will still be deliciously creamy.

How do I cut this 5-Minute Microwave Peanut Butter Fudge cleanly?

For clean cuts, line your baking dish with parchment paper, leaving some overhang. After the fudge is fully chilled, lift it out using the parchment paper. Use a sharp, large knife to cut the fudge into squares. For even cleaner cuts, you can warm the knife under hot water, dry it, and then cut.

Can I double this 5-Minute Microwave Peanut Butter Fudge recipe?

Yes, you can easily double this recipe. Use a larger microwave-safe bowl and increase the microwave time slightly, if needed. Use a 9×13-inch baking dish for the doubled batch. The chilling time will remain about the same.
