Chocolate Walnut Fudge

A simple 5-ingredient chocolate walnut fudge that you can create in your microwave. It’s a no-fuss, no-fail fudge recipe anyone can make!

Now that Thanksgiving is done, it’s time to focus on my favorite holiday, Christmas! That means warm, comforting dinners and sweet treats. For today, we’re sharing Kim’s chocolate walnut fudge.

It’s such a simple recipe. Using your microwave, the fudge is ready to chill in about 4 minutes. I’ll provide some tips below to simplify the process even more. So, shall we get started?

Oh, if you like this recipe, then check out our Bailey’s Irish Cream fudge or our Rocky Road fudge. Both options are great for the holidays.

How to make chocolate walnut fudge in the microwave:

First, grab an 8×8-inch square baking dish. Line the dish with parchment paper or aluminum foil.

Afterward, use non-stick cooking spray to grease the liner. Doing so will keep the fudge from sticking as it cools.

Sweetened condensed milk and chocolate chips in a heat-safe bowl.

Next, combine the butter, sweetened condensed milk, and chocolate chips in a large, microwave-safe mixing bowl.

After that, place the bowl into your microwave. Use the high-power (see tips below) setting and heat the ingredients for 3 to 4 minutes.

The chocolate and other ingredients melted in the bowl.

Be sure to stir the ingredients every 30-seconds in order to have a smooth, creamy fudge. Once the ingredients are properly incorporated, stir in the chopped walnuts.

Chopped walnuts added to the melted fudge.

Then pour the cooling chocolate into the prepare baking dish. Now, you can use a butter knife or rubber spatula to smooth out the fudge.

Also, give the pan a few subtle shakes (jiggle back and forth) on the counter-top. I use that method on cake batters too.

The fudge transferred to the prepared baking dish.

Last, place the fudge into the fridge (uncovered) to chill for about 3 hours. Once it’s set, cut it and serve.

That’s it, your chocolate walnut fudge recipe is done! Kim and I hope you enjoy it and wish you all the best 🙂

Chocolate Walnut Fudge Tips & FAQ’s:

  • We have a small 700-watt microwave, so we used the high-power setting. If you have an 1100-watt microwave, then I recommend using the medium power setting when heating the chocolate, condensed milk, and butter.
  • The larger the baking dish, the thinner your fudge will be. For example, if you use a 9×9-inch baking dish, then your chocolate fudge will not be as thick as ours.

Why is my chocolate fudge grainy?

Because you did not stir it enough during the melting process. Stirring fudge while melts and begins to cool will help create a smooth and creamy fudge. Also, using a good quality chocolate doesn’t hurt.

How do I cut perfect squares of fudge?

There are 2 ways to accomplish this task. One way is to run a sharp knife under hot water between each cut. The warm knife will make a cleaner cut.

Another option is to use a wire cheese slicer. I know sounds silly, but I use it to cut fudge (without nuts) and it works.

Hi Monika!

Sometimes moisture can form on the fudge when there is a quick temperature change after moving it out of the refrigerator or from a cool area to a warmer area. Hope that helps! Have a great weekend! :)
