Sweetened Condensed Milk Fudge Recipe

This sweetened condensed milk fudge needs three ingredients: 2½ cups (15 oz) semi-sweet chocolate chips, one 14 oz can of sweetened condensed milk, and 2 tablespoons of unsalted butter. It melts together in about 5 minutes over low heat, sets in the fridge in 2 hours, and gives you 16 squares from an 8 inch pan.

No candy thermometer, no boiling, no beating. The one thing to watch is the heat. Keep it low and take the pan off as soon as the chips are melted.

A friend first handed me a square of this in her apartment on a rainy afternoon. She had made it from pantry staples. I doubted it until I took a bite.

Chocolate Chips, Condensed Milk, and Butter: The Ratio

The rule is simple: 15 ounces of chocolate chips to one 14 ounce can of sweetened condensed milk. That is roughly equal weights, and it is what makes the fudge firm enough to cut. The 2 tablespoons of butter loosen the mixture slightly and give the squares a softer, creamier bite.

Check your bag before you start. Many chocolate chip bags hold 10 to 12 ounces, not 15. A 12 ounce bag is about 3 ounces short, and that missing chocolate is the most common reason this fudge stays soft and sticky. A kitchen scale settles it. Weigh them.

Use sweetened condensed milk, not evaporated milk. They sit next to each other on the shelf and the cans look alike, but evaporated milk has no added sugar and the fudge will never set.

Semi-Sweet, Milk, or Dark Chocolate Chips?

All three work, but they set differently.

• Semi-sweet: the one in the recipe card. Sets firm, slices clean, and the chocolate flavor is not too sweet next to the condensed milk.
• Milk chocolate: sweeter and noticeably softer. Give it an extra hour in the fridge and cut smaller squares.
• Dark chocolate: the firmest set and the least sweet. A good choice if you plan to top it with flaky sea salt.

Half semi-sweet and half milk chocolate is a nice middle ground for kids. Swapping part of the chips for peanut butter chips also works, and if you like that idea, my peanut butter fudge goes all the way.

Melting the Fudge Without Scorching It

Line an 8 by 8 inch pan with parchment, leaving extra hanging over two sides so you can lift the fudge out later. Grease the paper lightly with butter or nonstick spray.

Put the chips, condensed milk, and butter in a medium saucepan over low heat. A heavy pan helps. So does patience. Stir constantly with a silicone spatula and scrape the bottom as you go, because the condensed milk is thick and sugary and it catches on the base long before the chips are done. Brown flecks in the fudge mean it scorched.

At first it looks lumpy and stiff. After a few minutes it loosens into a thick, glossy mass that pulls away from the sides as you stir. When only a few small bits of chocolate are left, take the pan off the heat and keep stirring; they melt on their own. Vanilla goes in now.

Pour it into the pan right away and smooth the top with the spatula. It sets fast. Sprinkle flaky sea salt or chopped nuts within the first minute and press them in lightly, before a skin forms, or they fall off when you cut.

Chilling and Cutting Clean Squares

Refrigerate for at least 2 hours, until the center feels firm when you press it. Lift the block out by the parchment and set it on a board.

For 16 squares about 2 inches each, cut it into 4 strips, turn the board, and cut 4 strips the other way. Run a large knife under hot water, dry it, and wipe it clean between cuts. Sharp edges, no dragging. For a softer bite, let the squares sit at room temperature for a few minutes before serving.

When the Fudge Goes Wrong

• Still soft after 2 hours: usually not enough chocolate (a 12 oz bag instead of 15 oz) or milk chocolate chips. Give it another hour in the fridge or 30 minutes in the freezer, and keep it chilled.
• Oily or greasy on top: the mixture got too hot and the butter separated. Take it off the heat and beat in a tablespoon of warm milk until it turns glossy again.
• Thick and dull, hard to stir: the chocolate seized from too much heat. Off the heat, stirring in that same splash of warm milk usually smooths it out.
• Dark specks or a bitter note: condensed milk scorched on the pan bottom. Next time, lower heat and keep scraping the base.

Toppings and Flavor Swaps

Flaky sea salt is my favorite finish because it cuts the sweetness. Chopped toasted nuts, toasted coconut, or a swirl of melted white chocolate dragged through the top with a toothpick all work too. A drizzle of homemade hot fudge sauce over the squares makes it double chocolate.

For seasonal versions built on the same idea, try eggnog fudge, maple fudge, Biscoff fudge, or chocolate coconut fudge. With a second can of condensed milk in the cupboard, chocolate truffles are the next thing I would make.

Making Fudge Ahead for Gifts

This is one of the best candies to make a week or two before the holidays. Store the squares in an airtight container with parchment between the layers so they do not stick.

• Room temperature: up to 1 week, soft and creamy.
• Fridge: up to 2 weeks, firmer.
• Freezer: up to 3 months in a sealed container. Thaw in the fridge, then let it sit out for a few minutes before serving.

For gift tins, cut the fudge a little smaller than usual and pack it in mini paper cases. Small squares travel better and go further on a cookie tray.

Quick Answers About Condensed Milk Fudge

Do you need a candy thermometer?

No. This fudge only melts chocolate into condensed milk, so there is no sugar to boil to a set temperature.

Can I double the recipe?

Yes. Use 5 cups (30 oz) of chips, 2 cans of condensed milk, and 4 tablespoons of butter in a 9 by 13 inch pan, and give it a little longer in the fridge.

Why is my condensed milk fudge grainy?

This kind of fudge is rarely grainy. A gritty or speckled texture almost always means scorched condensed milk, so melt it lower and scrape the pan bottom.

Pin this fudge to your holiday candy board so it is handy when gift season comes. If you try a new topping, tell me about it in the comments.
