Variations and Substitutions
Enhance Flavors: Add some vanilla frosting if you prefer to step this microwave peanut butter fudge up a notch. You could also stir in some sweetened condensed milk for a creamy version. Don’t have ganache? Just melt some dark or milk chocolate chips (or any type of chocolate chip) and drizzle the melted chocolate over the fudge! White chocolate would also taste good here.
Make It Vegan: For a vegan version, you could try using vegan butter with vegan sugar.
Make It Keto: For a keto version, use powdered Swerve instead of regular sugar.
Additions and Toppings: Feel free to add some throw in some sea salt flakes, shredded coconut, chopped nuts, or chocolate chips to the top of the fudge for bonus flavors. This fudge would also taste good with a little brown sugar added.
Expert Tips for Microwave Peanut Butter Fudge
Keep the pieces of fudge in an airtight container in the fridge for up to 2 weeks.
For best results, make sure the peanut butter and butter mixture is melted all the way.
Use a candy thermometer if you need to make sure the liquid is warm enough.
Use a sharp knife when cutting the fudge into small or large pieces.
Make sure to use caution when heating the peanut butter and butter in the microwave. Don’t burn yourself!
The corner pieces are the best part!
Fudge freezes well! Just place the fudge in a freezer-safe storage container or bag and freeze for up to two to three months.
If you like a less-sweet fudge, cut the amount of sugar in half. Then each piece of fudge will only have 219 calories and 7.5 grams of sugar!
