Root Beer Float Fudge

For the last two days of fudge week I have some unique fudge flavors for you.  Today’s recipe is for a root beer float fudge.  You get a yummy creamy root beer flavored fudge topped with fluffy white marshmallows to resemble to foam on top of a root beer float.

This recipe is one that requires a candy thermometer, but is worth making if you are willing to give it a try.  The way you make this fudge is just like the a recipe that my husband’s grandmother would make.  She had a delicious chocolate recipe that she made every year at Christmas.  I have made the recipe a few times.

Now with the way my husband’s grandma would make it, you had to beat the fudge forever with a wooden spoon.

 This task was given to my hubby’s grandpa when grandma made it, and he would cuss behind grandma’s back about having to do it.  One time when we were making it we actually broke the spoon in the process.  Now days, you don’t have to use a wooden spoon unless you really want to get a good arm work out.  You can use a Kitchen Aid mixer instead.  Now, I don’t know if any other mixer is strong enough, but I have done it with my Kitchen Aid.

The other thing about this recipe is you need to know what temperature is soft ball on your candy thermometer.  Don’t go by what the candy thermometer says.  This temperature can vary based upon where you live.  Here in Utah it is 230 degrees.  It can also vary slightly with each candy thermometer too.

By the way, t’is the season of giving and I have another giveaway going on right now!  Be sure to enter!
