Easy Chocolate Walnut Fudge Recipe

Traditionally, a chocolate fudge recipe involves a complicated process of heating and cooling the chocolate to just the right temperatures, to get just the right texture.

What is the secret to smooth fudge?

Traditionally, you need to cook homemade chocolate fudge to a specific temperature to form a sugar syrup, then let it cool to a specific temperature. This is the secret behind fudge’s smooth-yet-firm texture that’s still soft enough to cut. But, because this process can be complicated and time-consuming, I prefer to make a simplified fudge in the microwave.

Why make fudge with sweetened condensed milk?

In this microwave chocolate walnut fudge recipe, you don’t need to worry about specific temperatures or complicated steps. Since sweetened condensed milk is already a sugar syrup, you can simply melt it together with butter and chocolate to get a perfectly smooth fudge. Rather than making the sugar syrup from scratch, sweetened condensed milk shortens and simplifies the process!
