Microwave Peanut Butter Fudge (Gluten-Free, Dairy-Free)

The simplest microwave peanut butter fudge ever! Just 3 ingredients and 5 minutes of hands-on time to get a creamy, decadent and crazy good fudge oozing with peanut butter flavor! This is the perfect dessert for the holidays, and is also gluten-free, dairy-free, and vegan but it tastes so good no one would know!

What is Fudge?

I never tried fudge until early this year, and I have to say that it’s surely decadent and addictive.

For those who haven’t had fudge before, it’s is basically a sugar candy made from heating sugar, butter and milk and mixing the ingredients together until evenly combined. As it cools down, fudge solidifies and can be cut into desired shapes. Fudge originated in the US in the 19th century, and became increasingly popular as the cost of refined sugar decreased and also due to the fact that you can easily make fudge at home without any special equipment.

Peanut butter fudge is basically peanut-butter flavored fudge, with the main ingredients being peanut butter, powdered sugar, and butter.

Gluten-Free, Dairy-Free and Vegan Version

I wanted to make a gluten-free, dairy-free, and vegan version, so I swapped out the usual butter for refined coconut oil, which works just as well, and is completely dairy-free.

You literally need just 3 simple ingredients to make this homemade peanut butter candy, and best of all only 5 minutes of hands-on time is required. Plus, the best part is that you mix the ingredients in one single bowl, and heat them up in the microwave – which means no stovetop cooking or dirtying a pot or pan!

Less work, less cleanup, but equally delicious and decadent fudge – what’s there not to love about this version??

Ingredients You’ll Need:

Ingredient Notes/Substitutions:

• Peanut Butter: I used natural peanut butter for this recipe because it doesn’t contain any additives or preservatives. Learn how to make your own peanut butter in 10 minutes! However, you can also use creamy peanut butter (which will result in a thicker, more paste-like batter).

• Coconut Oil: I prefer using refined coconut oil in this recipe because it has a neutral taste (as opposed to extra virgin coconut oil that has a strong coconut taste). Alternatively, if you are not lactose-intolerant, feel free to use unsalted butter in equal quantities.

• Powdered Sugar: It’s important to use powdered sugar instead of granulated sugar as the granulated sugar will not dissolve well and you will find it grainy. If you are diabetic or insulin-resistant, I highly suggest that you use Lakanto Monkfruit Sweetener (which is a 1:1 substitute for powdered sugar with zero glycemic index).

How to Make Fudge in the Microwave

1. Line Pan with Parchment

Line a 10 x 7-inch pan with parchment paper (make the parchment long enough so that it hangs off on both sides of the pan and makes it easier to pull out the fudge later).

2. Combine and Microwave

In a large microwave-safe bowl, combine the peanut butter and coconut oil. Microwave on high heat for 1 minute and then whisk. Microwave for another 1 minute and whisk again until you get a smooth liquid mixture.

3. Add Powdered Sugar

Sift in the powdered sugar and whisk as well as you can. The batter will be a thick mixture.

4. Pour Batter into Pan

Pour the fudge batter into the prepared pan and use a spatula to smooth out the top.

5. Chill Until Set

Refrigerate the mixture for at least 3 hours until fudge has set and is firm to the touch.

6. Cut Fudge into Pieces

Use the parchment overhang to pull out the fudge from the pan and then cut into pieces. 

Helpful Tips/Tricks:

• Use Parchment for Easy Removal: Make sure to use parchment paper to line your pan before pouring in the liquid fudge mixture as this will make it much easier to remove the fudge from the pan once it’s solid and set.

• Add Chopped Peanuts/Nuts: If you want to have some kind of contrast in texture, feel free to mix in chopped peanuts or other chopped nuts or sprinkle them on top of the fudge mixture before chilling.
