Who else loves no bake holiday recipes? 🙋

I’m all about saving time when it comes to making dessert, especially during the holidays.

Typically I like to make a few different treats, but I try and pick 2-3 really easy recipes and then one recipe that takes more time – like cut out sugar cookies.

A few of my favorite classic no bake christmas recipes are english toffee, no bake butterscotch marshmallow bars, and tiger butter. All of these treats make one great christmas platter.

Ingredients to make peanut butter fudge

  • 1 & 1/2 cups white chocolate chips
  • 1/2 cup peanut butter
  • 1 can, 14 oz, sweetened condensed milk
  • 1/4 tsp salt
  • 1 tsp vanilla extract

Do the last 2 ingredients even really count as ingredients? So technically this could be a 3 ingredient peanut butter fudge recipe!

How to make microwave peanut butter fudge without marshmallows

  • Line an 8 or 9 inch square baking pan with aluminum foil or parchment paper.
  • Place all the ingredients in a microwave safe glass bowl. I recommend using a glass bowl because it evenly distributes heat.
  • Microwave for 1 minute on 50% power. Stir, then microwave for another 30-45 seconds on 50% power. Stir until smooth and melted. If the mixture is not fully melted, microwave for another 30-45 seconds on 50% power.
  • Quickly pour the fudge into the pan, using a spatula to smooth and distribute the fudge.
  • Allow it to cool on the counter for 2-3 hours. Then cut into pieces. For easier cutting, place in the fridge to chill for 30 minutes, then cut.

Why is my peanut butter fudge dry and crumbly?

Fudge is all about sugar crystallization. The number one reason fudge turns out dry and crumbly is because the fudge mixture was overcooked / overheated.

Unfortunately, with microwave fudge there is no good way to salvage overcooked fudge.

But I recommend microwaving the fudge ingredients in a glass bowl for even heating.

How to store fudge

Store fudge in an airtight container. Fudge will last for 2-3 weeks in a container on the counter.

If you want fudge to last longer (up to 4 weeks), store it in an airtight container in the fridge.

Can peanut butter fudge be frozen?

Yes! You can freeze fudge as a large slab or fudge that’s been cut into pieces. For either method, place the fudge in the fridge for 1 hour to chill, then wrap the fudge tightly in plastic wrap and place inside a zip lock freezer bag. Fudge can be stored in the freezer for up to 3 months.

To thaw, place the fudge in the fridge for 24 hours.

If you want perfectly square pieces of fudge, I recommend using a ruler and a sharp knife. Cleaning your knife between each cut will help create clean cut lines.
