5 Better Ways To Order A McDonald's McFlurry For 10X The Flavor

While many fast food ice cream desserts are highly customizable with different flavors and add-ins, the McDonald's McFlurry is steadfast in its simplicity. On the chain's permanent menu, you can get an Oreo McFlurry with the crushed cookies mixed into McD's vanilla soft serve, or a version with mini M&M's — but these two options aren't necessarily the be-all end-all. With a few ordering tricks, you can create a full range of custom McFlurries with 10 times the flavor and fun.

Fans of classic Oreo and M&M McFlurries may argue that they're perfect as-is, and we admit that their crunchy, creamy textures and nostalgic flavors make them two of McDonald's best desserts by far. But sometimes you pull up to the Golden Arches with a craving for a more substantial dessert, or you've got an itch for flavors besides chocolate and vanilla. In that case, you'll want to try the following hacks that take this iconic treat from brilliantly simple to awesomely over-the-top.

We scoured the internet for popular McFlurry hacks from McDonald's customers and employees alike, so you know that these custom creations are fairly easy to pull off and taste great. None of them require you to bring ingredients from home or do anything else too fussy, either. With our tips, you might never settle for a basic McFlurry again.

Several delicious McFlurry customizations are available right in the McDonald's app, no complicated "secret menu" hacks required. Just start a mobile order, select the McFlurry of your choice, tap the button that says "customize," and you'll get to choose from various tasty additions.

One way to give your McFlurry twice as much flavor is to combine both M&M's and Oreos in the app, creating a creamy, crispy treat that's truly the best of both worlds. You can even request a double serving of cookies or candy, but the McFlurry you select as your base matters. You can double the Oreos in an Oreo McFlurry, but you can only pile on one extra dose of M&M's. This works the other way around with the M&M McFlurry. The McDonald's app also lets you add hot fudge sauce, caramel, whipped cream, or all three for a tricked-out treat that's more like a classy ice cream parlor dessert than a fast food item.

Of course, you can also request these additions in person at your local Golden Arches, and the staff might even be willing to give you twice the Oreos and twice the M&M's in one cup. The only little snag is that each extra topping costs you 50 cents more in the app, and likely in-person, too. This may not be the cheapest dessert you can get at McDonald's, but it'll definitely be one of the yummiest.

This next McFlurry modification is a "secret menu" trick that you won't find on the McDonald's menu or app, but if you ask politely in person, the staff may be willing to pull it off for you. McDonald's chocolate shake is blended with a chocolate syrup that's different from the hot fudge you can add to sundaes or McFlurries, while the chain's strawberry shake contains a strawberry syrup that isn't used in any other menu items. Try asking for one (or both!) of these milkshake syrups to be blended into your McFlurry. If it's your lucky day, you'll wind up with an extra-chocolatey or delightfully fruity dessert.

Don't want to ask the staff for special requests? There's another way to add a fruity, syrupy twist to your McFlurry. Just grab a packet of McDonald's strawberry preserves or grape jam, squeeze it on top of your McFlurry, and mix to create some nice saucy ribbons throughout.

As a final tip, keep an eye out when McDonald's legendary Shamrock Shake and Shamrock McFlurry are on the menu. You might not know that you can get your Shamrock McFlurry with extra mint syrup when ordered through the McDonald's app, seriously ramping up the refreshing mint flavor. The customization will cost you 30 cents extra, but the combo of extra-minty soft serve and chocolatey Oreos is a must-try for chocolate mint devotees.

To turn your McFlurry into a loaded frozen delight much like a Dairy Queen Blizzard, crumble up and mix in other McDonald's sweet treats. To try one of the most popular (and delicious) mashups, order the chain's iconic apple pie, plunk it into your McFlurry cup, and use your spoon to break up the pie before mixing thoroughly. You now have a McFlurry that tastes like apple pie à la mode, with flaky crust pieces, warm cinnamon apples, and cool, creamy ice cream. The best base for this dessert is probably a plain McFlurry — you can request one without Oreos or M&M's in the McDonald's app or in person.

If you prefer chocolate to fruit, crumble McDonald's chocolate chip cookies into your McFlurry. It'll taste just like cookie dough ice cream with an extra boost of Oreos or M&M's. Add hot fudge sauce and whipped cream on top, and you'll hardly believe that your gourmet dessert came from a drive-thru window.

You should also keep this ordering trick in mind for McDonald's limited-edition pies. The chain's seasonal Pumpkin & Crème Pie — which is back on the menu as of this writing — would make for a unique fall-inspired McFlurry. In June, McDonald's also brought back its Blueberry & Crème Pie, one of the best fast food desserts of 2026. While this treat has since left menus, keep an eye out for a future return, as it's ripe for turning into a blueberry pie McFlurry.

There's another awesome ordering hack involving a McFlurry and McDonald's chocolate chip cookies. You can turn these treats into a DIY ice cream sandwich by simply spooning the McFlurry onto one cookie, then adding a second cookie on top. The resulting dessert will be just like the Chipwich, one of the best ice cream novelties of all time, but with an unmistakable McFlurry flavor and a bonus helping of crunchy Oreos or crispy M&M's. Just try to assemble the sandwich quickly before the ice cream melts too much, and if it's a hot day and you're eating in the car, definitely grab plenty of napkins.

Do you love dipping French fries into a vanilla shake or soft serve? You'll want to know about a salty-sweet McDonald's ice cream sandwich hack: Order a McFlurry during breakfast hours and sandwich it between two crispy hash browns. As unconventional as it sounds, tons of McD's fans have tried this combination and declared it to be delicious. The salty, crunchy hash browns bring an addictive savory contrast to the sweet soft serve. Oreos or M&M's add even more decadent sweetness to the equation, but for a more pure potato-and-ice-cream experience, try making your sandwich with a plain McFlurry.

The humble McFlurry can turn into an unexpectedly elegant treat with just one addition. You can create a McDonald's version of affogato — the Italian dessert of espresso poured over vanilla gelato — by ordering a McFlurry and a shot of espresso, then pouring the coffee over the ice cream. It's not a part of the chain's main McCafé menu, but McDonald's does sell single shots of espresso if you ask.

This hack has been popular among customers for quite a while now, and it's easy to see why. The frozen creation delivers all the contrasting elements that make an affogato great, from the sweet-and bitter-flavors to the hot-and-cold temperatures, with added chocolatey goodness from the Oreos or M&M's. You can order an affogato-style treat at other fast food places that offer coffee and vanilla ice cream, but the McFlurry really makes for a special base.

For a different "secret menu" drink that trades grown-up espresso for nostalgic soda, create your own "McFloat" by dumping a small McFlurry into a large cup of soda. Coca-Cola, Barq's Root Beer, or Dr. Pepper would pair best with the chocolate and vanilla flavors, though Orange Fanta wouldn't be bad, either, creating a chocolate-covered orange flavor profile. This bubbly, creamy, sweet drink is sure to bring out your inner child.
