Ingredients needed for Microwave Fudge
Peanut Butter. Peanut butter is a good source of protein, healthy fats, and fiber. It also has a rich, nutty flavor that can add depth to many dishes. If you can’t have peanut butter or just want to switch it up, try almond or cashew butter, sunflower seed butter or tahini.
Coconut oil. Coconut oil is high in healthy fats which are quickly metabolized for energy by the body.
Agave Nectar. Agave nectar is a popular alternative to refined sugar because it has a lower glycemic index, meaning it is less likely to cause a spike in blood sugar levels. If you want to sub in a different sweetener, try honey, maple syrup, or date syrup. Keep in mind that these substitutes may have slightly different flavors and sweetness levels than agave nectar, so you may need to adjust the amount used in your recipe accordingly.
How to make Peanut Butter Microwave Fudge
Microwave. It’s always best to melt the coconut oil before measuring. Place the coconut oil in the microwave for about 1 minute until liquid-y.
Mix. Measure all the ingredients and add them to a large bowl. Whisk until the ingredients are smooth.
Transfer. Line a bread pan with parchment paper. I like to fold the parchment so it hangs over the two long sides of the pan and I clip them in place with paper clips or chip clips. Pour the peanut butter mixture into the pan.
The contents should settle itself into the edges and corners but if it needs some help, give the pan a little jiggle so it settles into an even layer.
Chill. Place the pan in a freezer on a flat surface so the fudge sets evenly.
Chill for about 1 hour or more until the fudge is set.
Cut. Glide a knife around the edges of the fudge that are touching the sides of the pan and pull the parchment edges to remove the fudge from the pan.
Cut the fudge into squares. I cut mine into 18 squares. Sprinkle with flakey salt for the most delicious sweet and salty combo.
Enjoy! Store in an airtight container or large plastic bag in the fridge.
Tips for Success
Here are some tips for making a successful peanut butter fudge recipe in the microwave:
Use delicious peanut butter: Because this recipe has only three ingredients, it’s important to use a peanut butter you love! All the rich, creamy flavor and texture comes from the peanut butter so make sure to grab a brand you love.
Line the dish with parchment paper: To make it easier to remove the fudge from the pan, line it with parchment paper before adding the fudge mixture. Using parchment paper will allow you to lift the fudge out of the pan and cut it into squares more easily.
Keep it chilled: After allowing the fudge to firm up in the freezer, make sure to store it in a cool place. I like to keep mine stashed away in the back of my fridge. The fudge will melt if kept in a warm place so make sure you store it chilled.
Variations on this Microwave Peanut Butter Fudge
Peanut butter fudge is delicious on its own, but there are many ways to add additional flavors and switch it up. Here are some flavor variations you can try for peanut butter fudge:
- Chocolate peanut butter fudge: Melt some chocolate chips and swirl them into the peanut butter fudge mixture before chilling. You can also sprinkle chopped chocolate on top of the fudge before it sets.
- Nutty peanut butter fudge: Add chopped peanuts, almonds, or other nuts to the fudge mixture before chilling.
- Cinnamon peanut butter fudge: Add a pinch of cinnamon to the fudge mixture for a subtle kick.
- Maple peanut butter fudge: Use maple syrup instead of the agave nectar called for in the recipe to give the fudge a warm, maple flavor.
- Coconut peanut butter fudge: Stir in some shredded coconut to the fudge mixture before chilling. You can also sprinkle shredded coconut on top of the fudge before it sets.
- Marshmallows: stir in some mini marshmallows or sprinkle them on top before you set the fudge in the fridge.
How to Store them
To store fudge, it’s important to protect it from moisture and to keep it at a cool temperature. Here are some tips for storing your peanut butter fudge:
Store in an airtight container: Place the fudge in an airtight container or wrap it in plastic wrap. This will prevent air and moisture from getting in and keep the fudge fresh for longer.
Refrigerate or freeze: Fudge can be stored in the refrigerator for up to two weeks, or in the freezer for up to three months. If you’re storing it in the freezer, wrap it in plastic wrap to prevent freezer burn.
Keep away from heat: Fudge can become sticky and lose its shape if it is exposed to heat. Store it in a cool, dry place away from direct sunlight and sources of heat, like ovens or stovetops.
