Holiday Fudge Recipe
Growing up, I loved those Brach’s Royals (filled caramels), and my favorite flavor was the Butter Rum. Does anyone remember these?
That rich buttery flavor was the inspiration for today’s fudge recipe. It turned out even better than I imagined. The flavor is nostalgic for me but to my kids it’s just plain delicious.
If you’re looking for a new fudge recipe to add to your holiday baking list, give this one a try. It’s going on my regular rotation along with Eggnog Fudge and Candy Cane Fudge.
Ingredient Notes
- Rum extract – This handy little extract is an amazing addition to the basic white chocolate fudge. Grab a bottle for this recipe and then you’ll be prepared to make Eggnog Truffles too!
- Butterscotch morsels – You’ll find these in the baking aisle next to the chocolate chips.
- White chocolate morsels – The white chocolate chips work best for quick melting in this recipe. If you can’t find any, you can use bars of white chocolate cut into tiny pieces as a substitute.
- Marshmallow cream – Also called marshmallow fluff, this ingredient is my secret to making soft and smooth fudge without a candy thermometer.
- Heavy cream – Remember to use real heavy cream for making homemade fudge, not milk!
Warning: once you learn how to make fudge without a candy thermometer you’re going to want to make it all the time.
Step by Step Instructions
Prepare the morsels and marshmallow. Add white chocolate and butterscotch morsels to a bowl along with the marshmallow fluff and rum extract, then set it aside.
Boil the cream and sugar. Bring butter, sugar and heavy cream to a boil in a saucepan, then let it boil for 5 minutes and keep stirring.
Combine. Immediately pour the hot butter mixture into the bowl with the marshmallow cream and morsels. Use electric beaters or a stand mixer to beat everything together until smooth.
Chill. Pour the fudge into a baking dish lined with parchment paper and let it chill in the refrigerator for at least two hours to set. Once set, cut the fudge into bite sized pieces and enjoy.
Aimee’s Pro Tip
For freshest tasting fudge, cut only what you will be eating right away, then store the rest as a block until you’re ready for more!

I’ve never tried this flavor! Sounds delicious!
Looks delicious! Perfect for the holidays!
Such an awesome idea for fudge! I love it!
Oh my! I have never tried this flavor but it looks irresistible!
This fudge is so rich and delicious – one of my all time favorites!
This butter rum fudge is my kind of sweet treat!
I remember those candy’s too! They were in an assortment that we got and I dug out the butter rum flavor or myself! All of them! Now I’m a big girl and the rum caught my attention and even though there isn’t alcohol in them I definitely know that I’m going to love these. They’re a great holiday gift idea too!
can i use dark rum instead of rum flavoring?
Rum flavoring is more concentrated than dark rum, so while you can use it, it won’t have the same flavor.
This is the best! Everyone that has tried it loved it!
WOnderful 🙂
How much butter and sugar?
all the ingredient amounts are listed in the recipe 🙂
I am officially sitting here drooling at the thought of a piece of this beautiful fudge along with the hot cup of chai I’m sipping on. I’m definitely going to have to make some of this as those butter rum flavored Brach’s Royals were my favorites too. Thank you in advance for the added pounds I am about to (happily) receive. Lol
haha you’re very welcome. And yes, those Butter Rum Royals are the best 🙂
Can you substitute mini marshmallows for the fluff?
I haven’t tried that!
Can I use my stand mixer or should it be a hand mixer? I’ve seen some fudge recipes make a distinction before.
I usually use my stand mixer for fudge.
I definitely need this fudge in my life!!! Yum!!!
I don’t like rum but I *love* butter rum as a baked good flavor. This fudge looks fantastic!
I LOVE butter rum, so this sounds like the best fudge flavor ever!
