Description

The simplest microwave peanut butter fudge ever that’s big on flavor with a short ingredient list! 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!


Ingredients

Scale

Instructions

  1. Line Pan with Parchment: Line a 10 x 7-inch pan or an 8 x 8-inch square pan with either wax paper or 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 Peanut Butter and Coconut Oil: 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 into Pan: Pour the 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. Use the parchment overhang to pull out the fudge from the pan and then cut into pieces. 

Notes

Peanut Butter: I used natural peanut butter because I like that it doesn’t contain any additives or preservatives. 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 flavor (as opposed to extra virgin coconut oil that has a strong coconut smell and taste). You may also use unsalted dairy-free butter (vegan butter) if you prefer. 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 (also known as confectioner’s 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 powdered monkfruit sweetener (a 1:1 powdered sugar substitute with zero glycemic index and will not raise your blood sugar).

Storing/Freezing: As this fudge will melt if left out the fridge for too long, make sure to place the fudge pieces in an airtight container, or cover with plastic wrap or aluminum foil and store in the refrigerator for up to 2 weeks. To freeze, place fudge pieces in a freezer-safe container and freeze for up to 3 months. Let fudge thaw at room temperature for 15 minutes before serving and eating.

This recipe was originally posted in December 2020, but has since been updated to include clearer step-by-step instructions, as well as better ingredient notes and substitutions.
