Simple Ingredients for Microwave Fudge Recipe

  • Semi-Sweet Chocolate chips | Just like my hot chocolate, we’ll use real chocolate chips for hot cocoa part of the recipe; use semi-sweet chocolate chips or dark chocolate chips. Or, if preferred, use milk chocolate chips.
  • White Chocolate Chips | Use white chocolate chips for a beautiful two-tone fudge recipe. 
  • Condensed milk | Sweetened condensed milk – you can use regular or dairy-free sweetened condensed milk. 
  • Marshmallows | I like to use tiny marshmallow bits to represent the marshmallows that top a classic cup of hot chocolate. They are dehydrated marshmallows, adding a crisp texture to the fudgy bites.

How to Make this Easy Microwave Fudge Recipe

Step 1 | Prep the pan

First, let’s get the supplies ready. Line a small square pan with parchment paper or aluminum foil and coat it with cooking spray or spray oil.

Step 2 | Melt and chill semi-sweet chocolate

Add semisweet chocolate chips and sweetened condensed milk to a medium microwave-safe bowl. Heat the ingredients in 30-second intervals, stirring between each, until the chocolate is melted. This may take about one minute.

Pour the chocolate mixture into the prepared pan and smooth the top with a spoon or offset spatula. Then, place it in the refrigerator for about 15 minutes.

Step 3 | Melt white chocolate

Next, combine the white chocolate chips and sweetened condensed milk in another medium bowl and heat for 30-second bursts, stirring between each. The chocolate should take about a minute to melt completely.

Fresh Tips

  • Heat the chocolate no longer than 30 seconds at a time to prevent it from seizing up. Check out my Chocolate Ganache recipe to learn how to fix this issue if it occurs.

Step 4 | Add the fudge layers

When the dark chocolate sets, add spoonfuls of the white chocolate and gently spread it over the dark chocolate, I like using an offset spatula. Then, evenly sprinkle on the tiny marshmallows and gently press them onto the surface.

Step 5 | Chill, slice, and serve!

Finally, place the hot chocolate fudge in the fridge and chill for at least three hours, but overnight is best. Slice it into one-inch cubes just before serving. Enjoy!

Fresh Tips

  • Wait for the fudge to chill before cutting using a large, sharp knife dipped into boiling water, then dried. The heat helps to make a clean and easy slice.
  • It’s best to heat the white chocolate right before adding it. It cools some as it sits. If needed, rewarm, a few seconds until pourable.
  • If preferred, use the double boiler method to melt the chocolate over medium heat.

Variations & Substitutions

  • Peanut Butter Fudge: Change the recipe up and top the fudge with creamy peanut butter swirled with chocolate fudge sauce. Then chill until set.
  • Mexican Hot Chocolate Fudge: Add a dash or two of cinnamon while melting your dark chocolate for yummy Mexican hot chocolate fudge. 
  • White Chocolate Peppermint Fudge: Add ¼ teaspoon of peppermint extract to the chocolate during the melting stage. Then, sprinkle the tops with marshmallows and crushed candy canes.
  • Oreo Hot Chocolate Fudge: Mix crushed Oreos into the white chocolate layer, then top the fudge with marshmallows and more crushed Oreos!
  • Spiced Hot Chocolate Fudge: For more seasonal flare, sprinkle in a pumpkin spice blend or all your favorite fall spices, like cinnamon, nutmeg, cloves, and ginger. After topping with marshmallows, dust the top of the fudge with a little more cinnamon– Delish!
  • Caramel Hot Chocolate Fudge: Swirl the chocolate layers with caramel sauce for a delicious twist! Then, sprinkle with marshmallows and caramel candy bits.
  • Chocolate Marshmallow Fudge: Use chocolate mini marshmallows for a twist. Or, try the recipe with the rainbow-colored marshmallow bits!
  • Add vanilla extract if you’d like, but it’s unnecessary because sweetened condensed milk and chocolate chips already have plenty of creamy flavor.
  • Use classic chocolate sauce or try my hot fudge sauce recipe to add a chocolatey swirl to the white chocolate.
  • Chop the fudge into tiny bits to top ice cream sundaes!

Storage Tips

Countertop – Because there’s no heavy cream or unsalted butter, like with traditional fudge, you can leave the creamy hot chocolate fudge bites on the counter at room temperature in an airtight container for about a week. Use parchment or wax paper between layers to prevent sticking, if necessary.

Refrigerate – To keep leftovers longer, store them in an airtight container in the refrigerator for about three weeks.

How to Freeze Hot Fudge Chocolate

Freeze hot chocolate fudge by placing the bites in an airtight container for up to three months to enjoy them all holiday season! The marshmallow bits might get a little soft and chewy.

Then, enjoy straight from the freezer, or let them thaw in the fridge overnight to serve the following day.

Frequently Asked Questions

Why won’t my microwave fudge set?

Be sure to allow the fudge to chill for at least three hours. Leaving it in the fridge overnight produces the best texture for easy slicing.

What’s the difference between hot fudge and fudge?

Essentially, classic hot fudge sauce is like an unset and undercooked version of the confection fudge, try my recipe for easy hot fudge sauce on your next ice cream sundae! While they use similar ingredients, hot fudge is a common ice cream sauce and topping, and fudge is more of a whole dessert.

Why does my fudge crumble when I cut it?

It’s possible you overcooked the chocolate mixtures. If you notice the chocolate burning or hardening when melting it in the microwave, there’s a chance your final results will also be crumbly.

Gluten-Free Microwave Fudge

Make sure that your chocolate chips are gluten-free, the Jet-Puffed Marshmallow bits are gluten-free, if you use another brand, double-check.

Dairy-Free Fudge Recipe

If you want to make this microwave fudge recipe dairy-free or vegan, purchase or make a dairy-free sweetened condensed milk and purchase dairy-free chocolate chips.

Get Recipe Ingredients

Instructions

  • Prepare a small square pan (8 x 8 or 9 x 9) pan by lining it with parchment paper (or aluminum foil) and coating the parchment or foil with cooking spray.
  • In a medium microwave-safe bowl combine semisweet Chocolate Chips and 6 tablespoons (about half the can) Sweetened Condensed Milk, and microwave in 30-second bursts, stirring really well each time, until melted. It should take about 1 minute, tops. *Chocolate continues melting as you stir, so stir for at least 30 seconds between heatings.
  • Place the dark chocolate mixture into the 8×8 or 9×9 pan and smooth with a spoon or offset spatula—place in the fridge for 15 minutes to set.
  • Just as the 15 minutes are ending, begin melting your white chocolate chips. Add the rest of the can of sweetened condensed milk, to the white chocolate chips and microwave in 30-second bursts, stirring well each time, until melted. It should take about 1 minute, tops.
  • *Be sure to stir well between heating in the microwave; chocolate continues to melt while stirring! If you heat too long your chocolate will seize up on you!
  • When dark chocolate is set a little, add dollops of the white chocolate mixture (warm first if necessary), and carefully spread it over the dark chocolate base.
  • Sprinkle the tiny marshmallow bits over the top of the white chocolate layer and gently press into the fudge.
  • Place the fudge in the refrigerator and set for 3 hours or overnight. When set, cut into 1 x 1-inch squares and serve them at room temperature. Enjoy!

Notes

Fudge is much easier to cut when it’s chilled, chill at least 3 hours or overnight. For best results, dip a large, sharp knife in boiling water, dry it completely, and cut one long slice (the heat will help the knife to glide through), repeat the process with each slice; repeat for the opposite direction. Don’t forget to wipe the knife clean each time or you will have wet edges.
Storage Tips
Countertop – Because there’s no heavy cream or unsalted butter, like with traditional fudge, you can leave the creamy hot chocolate fudge bites on the counter at room temperature in an airtight container for about a week. Use parchment or wax paper between layers to prevent sticking, if necessary.
Refrigerate – To keep leftovers longer, store them in an airtight container in the refrigerator for about three weeks.
How to Freeze – Freeze hot chocolate fudge by placing the bites in an airtight container for up to three months to enjoy them all holiday season! Then, enjoy straight from the freezer, or let them thaw in the fridge overnight to serve the following day.
Gluten-Free Microwave Fudge
Make sure that your chocolate chips are gluten-free, the Jet-Puffed Marshmallow bits are gluten-free if you use another brand, double-check.
Dairy-Free Fudge Recipe
If you want to make this microwave fudge recipe dairy-free or vegan, purchase or make a dairy-free sweetened condensed milk and purchase dairy-free chocolate chips.
