Can't wait to tell you about my fun spin on that famous McDonald's spring shake transformed into fudge! This velvety dessert comes in a gorgeous green shade and gives you pure vanilla bliss in every bite. Works great for St. Patrick's gatherings or whenever you want to whip up something fun that'll get everyone grinning.
Why This Fudge Stands Out
Whenever I cook up this fudge, it instantly brings back memories of sipping those mint green shakes during my childhood. The final product turns out incredibly silky and lush, with that eye-catching green hue that just yells celebration. And guess what? It's actually way simpler to create than most people think!
Shopping List Items
- Sugar: 2 cups total (go for superfine if possible)
- Butter: 1/2 cup unsalted, try to get European style
- Ice Cream: 1/2 cup vanilla, needs to be softened
- Salt: Only 1/4 teaspoon needed
- White Chocolate: 1 cup chips (worth getting Guittard brand)
- Marshmallow Creme: 1 jar (7 oz)
- Vanilla: 1 teaspoon pure extract
- Green Color: Several drops for that nice color
Fudge Creation Steps
- Getting Ready
- Put parchment paper in your 8x8 baking dish so you can easily pull out the fudge later.
- Begin The Cooking
- Mix your sugar, butter, ice cream, and salt together in a saucepan. Warm it up while continuously stirring until everything combines and starts to bubble up.
- Mind The Heat
- Continue cooking and stirring until you reach 234°F on your thermometer - that's exactly when your fudge will turn out perfect.
- Mix In Extras
- Remove from heat, toss in the white chocolate chips and stir until melted. Then add your marshmallow cream, vanilla, and enough green coloring to get that lovely shade.
- Setting Time
- Transfer the mixture to your prepared pan and flatten the surface. Let it cool at room temperature for about two hours, then move it to the fridge.
- Ready To Enjoy
- Slice into squares and watch them quickly disappear! Store any leftovers in a container - they'll stay fresh for a week.
Custom Variations
Need more mint flavor? Just add a bit of mint extract. I sometimes throw in crushed mint candies too. Try topping with green sugar crystals for extra festive look!
Pro Pointers
Don't skip on getting a reliable thermometer - it really matters. Go for high-quality butter and chocolate if you can - you'll taste the difference. And if you don't have superfine sugar, just pulse regular sugar in your blender for a few seconds!
Keeping It Fresh
This fudge tastes better when it's slightly room temperature rather than cold from the fridge. It'll remain delicious for a week in an airtight container. Need to keep it longer? Wrap it carefully and stick it in the freezer - it'll last up to two months!
Creative Finishing Touches
I occasionally top pieces with small swirls of whipped cream and cherries just like the actual shake! For adult gatherings, try adding a splash of Irish cream liqueur - it's absolutely delightful!
Equipment Checklist
You'll need a sturdy pot, candy thermometer, parchment paper, and a durable spatula for mixing. An 8x8 baking dish creates the ideal thickness and makes cutting super straightforward.

Delightful Celebration Treat
This fudge always takes me back to enjoying those seasonal spring shakes! Its stunning green color and smooth texture make it ideal for St. Patrick's Day events. Everyone always wants to know how I made it!
Frequently Asked Questions
- → What can I substitute for green chips?
You can use regular mint chips and add a bit of green food dye. Or mint extract plus white chocolate chips with coloring works too!
- → Is a candy thermometer necessary?
You need it to get the perfect fudge consistency. If the temp’s off, your fudge might be too hard or too soft. Make sure your thermometer works properly beforehand.
- → Can I try other ice cream flavors?
It’s best to stick with vanilla since it keeps things creamy without overpowering the mint flavor or changing the color.
- → My fudge won’t set—what went wrong?
It didn’t reach the right heat level. Be sure it hits 234°F. And don’t make fudge on humid days, as it might not firm up properly.
- → What’s the best way to store it?
Keep it in a sealed container at room temperature for about a week. Skip the fridge to avoid a grainy texture.
