I really love the flavors of spiced rum. It adds in a nice touch of cinnamon and vanilla without being overpowering. I used a limited edition of Captain Morgan Spiced Rum. But you can use regular spiced rum if you have it.

Fresh lime juice, blackberries, and rosemary add herbaceous, fruity flavor and give this Blackberry Moscow Mule tons of flavor.

Coconut activated charcoal powder is the perfect way to make a drink black without really changing the flavors. Plus it is supposed to have really great benefits.

I used to take an activated charcoal capsule to help me with hangovers (not a doctor – not health advice and I now use these hangover supplements) because mine are super atrocious. But it’s also great for digestion and cleaning teeth. You can find out all about it here.

Ginger beer is just a classic Moscow Mule flavor so it’s a must. Do not use Ginger Ale. It’s too sweet and lacks the bite of ginger.

Adding a splash of prosecco or sparkling wine really brought out the fruity side. It’s a trick I’ve learned over the years. A splash of bubbles can really help a so-so drink.

Adding a little sweetness, like from the wine, can really help balance a cocktail if it feels like it’s missing something.

Enhance the blackberry flavor

I like to keep recipes as simple as possible so I try to always muddle fresh fruit to add flavors to drinks. In this case, you may want even more blackberry flavor and there is a few ways you can do that.

You can use Chambord (blackberry liquor) instead of or along with fresh muddled berries.

Don’t want to add any more alcohol? You can add a little blackberry simple syrup instead. It has a more concentrated berry flavor but will also add more sweetness to the drink so start with a little and taste before adding more.

How to Make a Halloween Mule

3. Add spiced rum

4. Add the charcoal

The activated charcoal gives it that creepy color but doesn’t change the flavor. You can skip this part if you don’t want to buy a specialty ingredient.

5. Mix well

A bar spoon is great to use because it’s small and can really get to the bottom of the glass.

6. Finish with ice and ginger beer

Add ice to the copper mug.

Then top with ginger beer. Use about 2-3 ounces. It may not fill the cup all the way up but to keep the flavors balanced, you only want a few ounces.

You don’t want your Halloween Moscow Mule to only taste like ginger beer.

Give it a quick taste and see if you want to add a little extra sweetness and fizz.

Then top the Blackberry Moscow Mule drink with prosecco or sparkling wine if using.

7. Garnish

Garnish with a rosemary sprig and eyeballs. I guess the eyeballs can be optional.

But really, it’s Halloween. Eyeballs should be a given. (They are not edible. Just creepy). You could even glue or stick one on a skewer to make a fun garnish.

Tips and Tricks

The blackberry flavor just wasn’t coming through when I first made this Halloween Moscow Mule. In this recipe, I muddle the fruit and herb together but it is a pretty subtle flavor. For an even more concentrated flavor, you can use blackberry simple syrup (or buy one here). I don’t love sweet drinks so I prefer to muddle. But they are a great way to add more concentrated flavors to cocktails.
I don’t mind having pieces of fruit or herbs in my cocktail. But if you do mind, you can strain the cocktail. Use a cocktail pitcher to make the drink and strain as you pour it into the copper mug. Or if you really wanted to, you could make this Halloween Mule drink in a cocktail shaker and then double strain it from there into a glass with ice.
If you aren’t a fan of rosemary, you can swap it out for almost any other fresh herb.
Want more herb flavor? You can make a blackberry rosemary simple syrup!

Frequently Asked Questions

Can I use activated charcoal in other recipes?

Yes! I also used activated charcoal to make a Vodka Halloween Punch. It’s a yummy citrus punch that is totally black! You could even just add it to apple juice if you want to make a spooky drink for the kids.

Is activated charcoal safe to eat?

Yes. It’s perfectly safe to consume in small amounts, but if you take certain medications it can impact how they work. Always err on the side of caution and check with your doctor if you have concerns.

What’s in a Moscow Mule?

A traditional Moscow Mule is made with vodka, lime juice, ginger beer and finished with a sprig of mint. They can sometimes include a few dashes of bitters or a little bit of simple syrup. It’s a great cocktail base that can be modified with all kinds of flavors like my Holiday Mule or Green Mule for St. Patrick’s Day.

Do you have to use a copper mug?

No. BUT – a copper mug is designed to keep a cocktail super chilled and extra refreshing. A Blackberry Moscow Mule is delicious when sipped from a copper mug but will still taste great from another glass.
