I can't wait to tell you about my spin on that famous green McDonald's shake transformed into fudge! This silky creation has the most gorgeous mint-green shade and tastes like pure vanilla bliss. It's fantastic for St. Patrick's gatherings or whenever you want to whip up something that'll bring smiles all around.
Why This Fudge Stands Out
Whenever I create this fudge, I'm instantly transported to my childhood days of slurping those green minty shakes. It turns out incredibly velvety, with that beautiful green tint that just yells celebration time. And guess what? It's actually much simpler to make than most folks think!
Shopping List Items
- Sugar: 2 cups total (try to get superfine for best results)
- Butter: 1/2 cup unsalted, go for European style if possible
- Ice Cream: 1/2 cup vanilla, slightly melted
- Salt: A small 1/4 teaspoon amount
- White Chocolate: 1 cup chips (worth paying extra for Guittard)
- Marshmallow Creme: 1 jar (7 oz)
- Vanilla: 1 teaspoon pure extract
- Green Color: Several drops for that perfect shade
Fudge Creation Steps
- Prep Work
- Put parchment in your 8x8 baking dish so you can easily pull everything out later.
- Mixing Base
- Combine your sugar, butter, ice cream, and salt in a saucepan. Warm it up while continuously stirring until everything combines and starts to bubble.
- Temperature Matters
- Continue cooking and mixing until your candy thermometer reaches 234°F - that's the sweet spot for perfect fudge texture.
- Mix In Extras
- Remove from heat, toss in white chocolate chips and stir until fully melted. Then blend in marshmallow cream, vanilla, and enough green coloring to get that eye-catching shade.
- Setting Time
- Pour everything into your prepared pan and level the surface. Let it sit at room temperature for about two hours before moving to the fridge.
- Serving Moment
- Slice into small squares and watch them quickly vanish! Store any leftovers in a container - they'll stay fresh for a week.
Customization Ideas
Need more mint flavor? Just add a bit of mint extract. I sometimes throw in crushed mint candies too. Sprinkling green sugar on top makes it look even more festive!
Pro Tricks
Invest in a reliable thermometer - it's super helpful. Pick the highest quality butter and chocolate you can afford - it really shows in the taste. And if you don't have superfine sugar, just give regular sugar a quick spin in your blender!
Keeping It Fresh
This fudge tastes way better when it's not straight from the fridge - let it warm up slightly before eating. It stays delicious for about a week in an airtight container. Want to save it longer? Wrap it well and stick it in the freezer - it'll stay good for two whole months!
Fancy Finishing Touches
I love adding tiny swirls of whipped cream with cherries on top just like the actual shake! For adult gatherings, try adding a splash of Irish cream - it's absolutely amazing!
Tools For Success
You'll need a sturdy pot, candy thermometer, parchment, and a durable spatula for mixing. An 8x8 baking dish helps everything set perfectly and makes cutting super straightforward.

Delightful Celebration Treat
This fudge always brings back wonderful memories of those seasonal green shakes! Its beautiful color and smooth texture make it ideal for St. Patrick's Day celebrations. Everyone always wants to know how I made it!
Frequently Asked Questions
- → What if I can’t find mint chips?
Use regular white chocolate chips with a little mint extract and green coloring. Or throw in any mint chips you have on hand and add some dye!
- → Why should I use a candy thermometer?
It’s all about getting the right texture! Without it, the fudge could end up too gooey or way too hard. Double-check your thermometer reads correctly first.
- → Can I use flavored ice cream?
It’s better to stick with vanilla. That way, the mint flavor shines through and you avoid color changes.
- → Why isn’t my fudge firming up?
You might not have heated it enough. It needs to hit 234°F. Also, try not to make fudge when it’s super humid outside—humidity can mess it up.
- → How do I store this fudge?
Stick it in an airtight container at room temp for about a week. Refrigeration isn’t ideal since it can mess with the texture.
