McDonald’s might be famous for its Big Macs and fries, but there’s a whole underground menu that most folks don’t know about. These secret items are crafted by creative fans, clever hacks, or whispered employee tips.
Some are mashups, others are offbeat twists—but all are worth a try if you’re up for a delicious adventure. Get ready to level up your next Mickey D’s visit.
1. The McGangBang

This one’s legendary. It’s a McChicken stuffed inside a double cheeseburger. People love the spicy-crispy-meaty combo, and it’s easy to make if you order both sandwiches and combine them yourself. The flavors hit hard—beefy, crunchy, and over-the-top.
2. Land, Sea & Air Burger

Everything in one bite. This beast includes a beef patty, McChicken filet, and Filet-O-Fish all in one towering sandwich. It’s wild, messy, and surprisingly tasty. You’ll need to order the three sandwiches separately and stack them into one epic creation.

3. The Poor Man’s Big Mac

All the flavor, half the price. Ask for a McDouble with Big Mac sauce and no ketchup or mustard. You get the classic Big Mac taste without the middle bun and with a friendlier price tag. It’s a smart hack for budget cravings.
4. Apple Pie McFlurry

Dessert done right. Order a McFlurry and an apple pie. Then crumble the pie into the McFlurry. The warm pie mixed with the cold ice cream? Pure magic. It’s creamy, cinnamony, and everything dessert dreams are made of.
5. Grilled Cheese

Perfect for picky eaters or vegetarians. Just ask for a bun with melted cheese. That’s it. It’s simple, buttery, and surprisingly satisfying when you need something warm and cheesy without the meat. Especially good for kids.

6. Chicken Cordon Bleu McMuffin

Breakfast with flair. Order an Egg McMuffin and a McChicken. Swap out the sausage or bacon and insert the crispy chicken patty. It’s a bold twist with a kick. Think crispy chicken meets melty egg and cheese.
7. Hash Brown McMuffin

Crunch meets comfort. Slide a hash brown inside your breakfast sandwich for a golden crunch. It adds a crispy layer and extra flavor. People swear by this texture boost—it turns a basic sandwich into a winner.
8. The Monster Mac

This burger is not for the faint of heart. It’s basically a Big Mac with eight patties. That’s right—eight. You may need to explain it carefully when ordering. But if you’re hungry enough, it’s a monster worth meeting.

9. Big Mac ‘n’ Cheese

Not official, but still loved. Order a side of mac and cheese (if available in select locations) and add it to a Big Mac. The gooey, cheesy pasta mixed with the burger layers is indulgent and bold. Limited but legendary.
10. Neapolitan Shake

Why pick one flavor? Ask for a shake that blends vanilla, chocolate, and strawberry together. It’s layered, colorful, and has all three classic flavors in one cool treat. A nostalgic favorite for shake lovers.
11. McCrepe

A breakfast dessert mashup. Get hotcakes and a yogurt parfait. Wrap the parfait in the hotcake and drizzle with syrup. It’s sweet, fruity, and soft—a breakfast that feels like dessert.

12. The Surf & Turf

A burger-fish fusion. Combine a McDouble with a Filet-O-Fish for a land-and-sea blend. The beef and fish combo might sound odd, but the tartar sauce and beef flavor make it interestingly addictive.
13. Ice Cream Sandwich

Your own frosty dessert creation. Order two cookies and a soft-serve cone. Scoop the ice cream between the cookies and press gently. It’s sweet, melty, and hits the spot on a hot day.
14. Fries with Big Mac Sauce

It’s like dipping into heaven. Order a side of Big Mac sauce with your fries. The tangy, creamy sauce turns regular fries into something unforgettable. It’s a small change with big flavor.

15. Mc10:35

A time-based treat. Show up around 10:35 a.m. and order an Egg McMuffin and a McDouble. Combine them. The mix of breakfast and lunch in one sandwich is peak brunch energy. It’s rare—but worth the timing.
16. Double Filet-O-Fish

More fish, more flavor. Ask for a Filet-O-Fish with two fish patties instead of one. It’s extra crispy, more filling, and makes the often-overlooked sandwich a serious contender.
17. Cinnamon Melt A La Mode

A warm-cold combo. Take a Cinnamon Melt (or hotcakes if that’s all you have) and top it with soft serve. The contrast between hot and cold is dreamy and delicious.

18. McFloat

A retro sip with a fast-food twist. Ask for a soft-serve cone in your soda—usually Coke or root beer. It’s fizzy, creamy, and instantly nostalgic. Not on the menu, but staff will often help if asked nicely.
19. Spicy McNugget Buffalo Sandwich

Bring the heat. Order Spicy McNuggets, add them to a bun with lettuce, cheese, and buffalo sauce. It’s crunchy, spicy, and bold—a fan-favorite for heat lovers.
20. Double Cheeseburger With Egg

It’s like brunch in a burger. Order a double cheeseburger and a breakfast sandwich with egg. Slide the egg into the burger and taste the magic. It’s savory, rich, and a little unexpected.

21. Onion Ring Burger (Where Available)

A crispy surprise. In regions that offer onion rings, stuff a few into your burger. They add crunch and flavor that kicks things up a notch. Great with BBQ sauce, too.
22. Poutine Fries (Canada-Style)

Some locations (especially in Canada) serve them. Ask for fries with cheese curds and hot gravy if available. If not, improvise with cheese slices and hot brown sauce. It’s rich, gooey, and comfort food at its finest.
23. Fried Chicken Big Mac

No beef, just bird. Swap Big Mac patties with two McChicken filets. Keep the lettuce, pickles, and Big Mac sauce. It’s crispier and lighter but still packs a flavorful punch.

24. Oreo Pie McFlurry

Mash up dessert legends. Crumble a McDonald’s Oreo pie (or cookies if pies aren’t available) into a McFlurry. It’s extra chocolatey and full of crunch. Basically a dessert explosion in a cup.
25. DIY Breakfast Tacos

It’s not on the board—but it’s delicious. Use sausage patties, scrambled eggs, and hotcakes to create your own breakfast taco. Roll it up, drizzle with syrup or hot sauce. Sweet, savory, satisfying.
