Kraft Fantasy Fudge

Fantasy Fudge is the name Kraft gave to the fudge recipe printed on the back of its Jet-Puffed Marshmallow Creme jars, which has appeared there since at least the early 1970s. The name reflects the recipe's improbable quality — smooth, creamy, professional-tasting fudge achievable in under 15 minutes of active work, without a candy thermometer or advanced technique. It became one of the most-replicated holiday recipes in American food history because it consistently works in every home kitchen. 'Fantasy' refers to the result: a fudge texture that would normally require the skills of a professional confectioner, delivered by a foolproof method that anyone can follow.

Fantasy Fudge uses evaporated milk — plain canned milk with about 60% of its water removed, no added sugar. Sweetened condensed milk (Eagle Brand) is a different product with significant added sugar, about 40% by weight. They are not interchangeable in this recipe. Using sweetened condensed milk instead of evaporated milk will add an extra layer of sweetness and may prevent the fudge from setting properly, because the sugar ratio and boiling behavior changes dramatically. For Fantasy Fudge, buy the 5-oz can of evaporated milk (Carnation is the most widely available brand) — one can is exactly ⅔ cup. If you have a 12-oz can, measure out ⅔ cup and refrigerate the rest for another use.

The most common cause is undercooking: the sugar mixture didn't reach the soft-ball stage (234°F / 112°C). If you're not using a thermometer, 'full rolling boil' means a boil that continues bubbling vigorously even when you stir — not just small surface bubbles. You need a full 5 minutes of that hard, active boil at medium-high heat, or 234°F on a thermometer. Underset fudge can sometimes be rescued: scrape it back into the saucepan, add 1–2 tablespoons of evaporated milk, bring it back to a full boil for 2 more minutes, re-add the chocolate and marshmallow, and pour again. High altitude is another culprit: water boils at a lower temperature above 3,000 feet, so the soft-ball stage occurs at a lower boiling temperature — add 1–2 extra minutes of boil time per 1,000 feet of elevation.

The sugar mixture scorches on the bottom of the pan almost immediately. Burnt sugar cannot be fixed — the batch must be discarded. Keep a heat-resistant rubber spatula or wooden spoon moving across the entire bottom and sides of the pan in slow, continuous strokes throughout the 5-minute boil. The mixture will bubble vigorously and may spatter, so be careful. Using a heavy-bottomed pan (3-quart Dutch oven or heavy stainless saucepan) significantly reduces the scorching risk because it distributes heat more evenly than thin pans.

Technically yes, but not recommended in a single batch. Doubling means the mixture takes longer to come to a full boil, it's harder to stir the entire bottom, and the thermal mass is harder to control — you're more likely to scorch it or overshoot the soft-ball stage. A better approach: make two full batches back to back. Each takes only 15 minutes of active work, and a full batch already fills a 13×9 pan and yields about 3 lbs of fudge (48 generous pieces), which is more than enough for most holiday gift-giving. If you do double, use a 6- or 8-quart pot and add at least 1 extra minute of boil time.

Stored in an airtight container at room temperature, Fantasy Fudge keeps for 2–3 weeks. Layer pieces between sheets of wax paper to prevent sticking. In the refrigerator it keeps for up to 4 weeks but may become slightly firmer and lose a little of its glossy surface. To gift or ship it: cut pieces, lay them on wax paper in a single layer, freeze for 2 hours until firm, then pack in gift boxes or tins with parchment between layers. Frozen fudge ships well via overnight or 2-day service and keeps frozen for up to 3 months. Thaw at room temperature for 1 hour before serving.
