This is a super-old recipe when Baker's Chocolate was just about the only option one had when baking. And when one could actually find a 13-ounce Hershey's chocolate bar.
Chocolate has come a long way.
As a teacher, I often made this fudge for students. And I made it for Christmas Open Houses when I owned an art studio. It adapts easily to additions, such as black walnuts. Because I don’t like it too sweet, I add an extra 2 ounces of unsweetened chocolate and then 2 ounces less milk chocolate. The original recipe calls for 13 ounces each of semi-sweet chocolate and Hershey's chocolate bar. You do you.
I found a few similar recipes on line but they use evaporated milk. I have not tried that. Below is a similar recipe from the blog "Real Life Dinner" that uses the evaporated milk and mini marshmallows instead of large. Most others use Fluff. Again, I have not tried that nor do I know how many marshmallows is equivalent to one jar of Fluff. Use whole milk, not reduced fat.
Have everything measured, chopped, and ready to go. Line your pan with parchment paper and then lightly butter it. I've made this without lining the pan and it's a nightmare to remove. And do not use tin foil.
I do not know how many cups of Fluff is equivalent to 25 marshmallows. I don't think Fluff existed back then. Use whole milk. Not 2 percent milk.
Avoid scraping the sides of the pot--it will make your fudge "grainy." After you pour it into your pan, do not scrape the sides clean--it will make you fudge grainy. Instead, just scrape it into a separate bowl for kids to dig into.
If you half this recipe, use an 8 x 8 pan.
In a large pot, mix the following ingredients:
- 1 cup whole milk
- 4 cups sugar
- 1 teaspoon vanilla
- 1 cup real butter
Remove from heat and add:
- 25 large marshmallows
- 2 oz. Baker’s Unsweetened Chocolate
- 13 oz. Baker’s Semi-Sweet Chocolate
- 11 oz. Hershey’s Milk Chocolate
Pour into a parchment-lined 12 x 16 metal sheet pan. Chill until set. Carefully remove from pan and remove paper. Cut using a heavy knife or bench scraper.
