How to Make Aunt Bill’s Brown Sugar Fudge (Step-by-Step)

In a large heavy pot, combine:

Stir to combine.
Step 3: Cook the Syrup

Frequently Asked Questions
Why is my fudge grainy?
It wasn’t beaten long enough or cooled too slowly. Beat vigorously until thickened.
Can I make this without nuts?
Yes! It turns out beautifully smooth and creamy.
Do I need a candy thermometer?
It helps, but old-fashioned cooks used the soft-ball test — drop a bit of mixture into cold water and see if it forms a soft pliable ball.
Can I double the recipe?
Yes, but use a very large pot — the mixture bubbles up.
