Why You Must Make

It was two days before we were to leave on our annual family vacation. Our oldest was coming by for dinner and I realized I only had bits and bobs of old cookies in the freezer.

  • This is a dessert that can be made with kitchen staples plus would last a couple of weeks in the fridge. This 3 Ingredient Chocolate Marshmallow Fudge from Hugs & Cookies XOXO fit the bill.
  • All you need is 12 ounces of semi-sweet chocolate, a bag of mini marshmallows, and a can of sweetened condensed milk.
  • My family loved this Eagle Brand Fudge and the cook didn’t have to break a sweat to make it.

How to Make

I am not the fudge nor the marshmallow eater in this family, but I found this quite tasty! The chocolate base had a more intense chocolate flavor as the semi-sweet chocolate wasn’t overloaded with sugar as in my No-Fail Fudge. But the marshmallows balanced out the sweetness perfectly. The menfolk enjoyed this fudge and I parked the leftovers in the fridge until we returned from the land of the midnight sun. No aurora borealis sightings, as it was too early to view the northern lights, but we had a marvelous time in Alaska.

  1. Line an 8×8-inch pan with nonstick foil. This serves a dual purpose: it prevents the fudge from sticking to the pan plus it acts as a sling to help lift the cooled fudge out of the pan for cutting.
  2. Combine chocolate and condensed milk in a microwave-safe bowl.
  3. Microwave in 30-second increments, stopping and stirring until smooth and melted.
  4. Stir in the marshmallows.
  5. Spread into the prepared pan and refrigerate for at least one hour.
  6. Cut into squares and serve.

How to Store

This Fudge with Sweetened Condensed Milk has a long lifespan. It can be kept at room temperature, in the refrigerator, or in the freezer.

  • PRO-Tip: Always store in an airtight container. Cut into squares and stack with a sheet of parchment or wax paper between the layers.
  • Keep it at room temperature for a week or so.
  • Store in the refrigerator for up to a month.
  • Freeze for 3-4 months.

Frequently Asked Questions

Is Fudge Better with Sweetened Condensed Milk or Evaporated Milk?

These two ingredients are not interchangeable and are used to make different types of fudge. Fudge with sweetened condensed milk uses minimal ingredients and can be made using the microwave.
Fudge made with evaporated milk is made on the stovetop, requires the fudge mixture to boil, takes more time, and uses more ingredients.

The texture of each type is unique and what one prefers is a personal preference.

How Do You Make Fudge with Condensed Milk?

A can of sweetened condensed milk and chopped chocolate or chocolate chips are melted together using the microwave in a heat-safe bowl, stopping to stir a few times until smooth. The marshmallows or other ingredients are mixed in before spreading the mixture into a prepared pan.

What Else Can Be Added to Fudge?

Nuts, dried fruit, chocolate chips (frozen to add texture without melting), chunks of frozen candy bars like Milky Way or Snickers, chopped Oreos, soft bits of caramel, bits of candy cane along with a touch of peppermint extract, etc. can all be added to a batch of fudge. The options are endless.
