The new McDonald’s McFlurry flavor is aptly named the Grandma McFlurry, and you’ll find the new flavor on menu boards nationwide on Tuesday, May 21, 2024.

Most McDonald’s locations serve up the McFlurry with a $4 - $4.50 price tag, but we’ve got a McDonald’s secret menu tip and a McDonald’s coupon to help you try this new McFlurry flavor — or any of your classic favorites — at a discounted price. 

Here’s how to save on the new Grandma McFlurry at McDonald’s. And for more smart shopping tips and McDonald’s savings hacks, text HACKS to 57299, and be sure to download the Krazy Coupon Lady app.

What is the new Grandma McDonald's McFlurry?


The Grandma McFlurry is a new flavor that hits all stores on May 21, 2024. It's rumored to taste like Werther’s butterscotch candies, this new flavor will be available for a limited time. It features a new Grandma McFlurry syrup — likely the nostalgic butterscotch flavor — and crunchy candy pieces, blended into their vanilla soft serve.

How to save money on the McDonald's McFlurry.

Use the 20% off coupon in the McDonald’s app to get a McFlurry for $3.72.

Through May 26, you can score 20% off $5 orders in the McDonald’s Rewards app. 

If your McFlurry rings in under the $5 minimum purchase, add an order of apple slices for under a buck. At my location in Michigan, I ordered a regular McFlurry ($4.19) along with the apple slices ($0.89) for a total of $5.08. With the 20% off coupon, I pay just $4.06 and save over a dollar.

Order a plain sundae with candy pieces for 20% less.

If your location allows it, you can order a sundae with toppings to save almost a dollar. Not all locations allow this, but if they do you can save around $0.82 on your order. 

At the location I tested in Michigan, a regular McFlurry is $4.19. If I order a sundae for $2.99 and add crushed candy topping for an additional $0.38, I pay just $3.37 — a 19.6% discount. 

Use the above-mentioned 20% off coupon to buy two Grandma-inspired sundaes for $2.70 each!

What other flavors of McFlurry are there?


The two classic McFlurry flavors you'll always find on the menu are Oreo and M&M. But McDonald's often releases limited-time or seasonal flavors.

Due to inflation, we haven't seen as many returning or new seasonal McFlurry offerings as some other regions. In fact, two returning seasonal flavors in 2024 were on menus in Canada and not the U.S.

And we didn't see a new flavor introduced at all during the November 2023 to January 2024 timeframe that normally has a new release. Instead, they released the Shamrock Shake and OREO Shamrock McFlurry earlier than ever before.

Here's what we've seen recently:

  • Coming Soon: May 21, 2024 — Grandma McFlurry

  • February 2024 — OREO Shamrock McFlurry

  • August 2023 — Peanut Butter Crunch McFlurry

  • March 2023 — Strawberry Shortcake McFlurry
