This is really simple to make. I actually just use the recipe right on the back of the Jet Puffed marshmallow creme jar. It takes about 25 minutes or so to make and is creamy and delightful!
3 cups sugar
3/4 cup (1 1/2 sticks) butter or margarine
1 can (5 oz) evaporated milk
12 oz semi-sweet chocolate
1 jar (7 oz) marshmallow creme
1 stp vanilla
Grease a 9 inch pan (you can also line the pan with foil with flaps over lapping the edges).
Bring sugar, butter and milk to full rolling boil in large saucepan on medium heat, stirring constantly. Boil for about 4 minutes or until 234 F on candy thermometer (but you really don’t need the thermometer to make this), stirring constantly. Remove from heat.
Add the chocolate and marshmallow creme (I alternate them in batches while incorporating and melting). Stir in vanilla (you can also add nuts if you like them).
Pour into pan.
I thought I would mix it up, and press mini pretzels into the fudge while it was still very warm thinking that the sweet with the salty would be a great mix. I didn’t like how it turned out, so I ended up picking them all off.

Yummy! This fudge was addicting!
My wife swears by the recipe on the back of the marshmallow bag. Love the addition of pretzels.
It’s been the simplest and best recipe that I’ve tried! I honestly was a bit disappointed with the pretzels 😦 I thought the salty crunch would add a lot of pizazz, but it didn’t wow me.
