McDonald’s Oreo Shamrock McFlurry Copycat Recipe
This McDonald’s Oreo Shamrock McFlurry copycat brings together that iconic mint vanilla soft-serve with crushed Oreos, right in your own kitchen. No drive-through required, and you can make it any time of year, not just when the seasonal menu decides to show up.
It comes together in about 5 minutes with a blender or hand mixer and ingredients you can grab at any grocery store. The result is cold, minty, and full of cookie crunch throughout.
Why I Love This Recipe
The mint flavor here is clean and cool without tipping into toothpaste territory, because you control exactly how much extract goes in.
The Oreo pieces stay crunchy when you fold them in at the end rather than blending them, which is the detail that makes this taste right.
This is the version I keep coming back to whenever the McFlurry disappears from the menu again.
Recipe Ingredients
- 2 cups vanilla ice cream – Full-fat gives the creamiest result; a good quality store brand works fine
- 3 tbsp whole milk – Loosens the texture so it churns smoothly; 2% works but goes slightly icier
- 1/2 tsp peppermint extract – Pure extract, not mint flavoring; the flavor is sharper and cleaner
- 2 drops green food coloring – Optional, but it gives you that recognizable shamrock green color
- 8 Oreo cookies – Standard original Oreo; double-stuf makes it harder to get even crumbles
- 2 tbsp heavy cream – Adds body and keeps the soft-serve texture from going icy fast
Variations / Substitutions
- Dairy-free – Swap vanilla ice cream for a coconut or oat-milk frozen dessert and replace heavy cream with full-fat coconut cream; the texture is slightly less thick but still good.
- More Oreos – Use up to 12 cookies if you want a heavier cookie-to-ice cream ratio, which is closer to the McFlurry’s actual crumble density.
- Less mint – Drop to 1/4 tsp peppermint extract for a subtler background flavor that lets the vanilla come through more.
- Extra green – Add 1 drop more food coloring at a time until you hit the shade you want; the color does not affect flavor.
- No peppermint – Leave out the extract entirely and fold in 2 tbsp hot fudge sauce instead for a plain Oreo McFlurry style.
If you enjoy making fast-food copycat drinks at home, the McDonald’s Shamrock Shake Copycat Recipe follows a very similar method.
How To Make Oreo Shamrock McFlurry
Step 1: Crush the Oreos
Place the 8 Oreo cookies in a zip-lock bag, seal it, and use a rolling pin or the bottom of a mug to crush them. You want a mix of sizes: some fine crumbs and some pieces about the size of a pea. Aim for about 30 seconds of medium pressure so you keep that range of textures.
Do not over-crush into pure powder. The bigger bits are what give you that satisfying crunch in the finished drink, so stop when the largest pieces are still visible.
Step 2: Blend the Mint Base
Add the 2 cups vanilla ice cream, 3 tbsp whole milk, 2 tbsp heavy cream, and 1/2 tsp peppermint extract to a blender. Add the 2 drops green food coloring if you are using it. Blend on medium speed for about 20 seconds, until the mixture is smooth and thick like soft-serve pulled straight from the machine.
It should pour slowly when you tip the blender jar, not flow freely like a milkshake. If it is too thin, add a small scoop of ice cream and blend for another 5 seconds.
Step 3: Fold In the Cookie Crumbles and Serve
Pour the blended mint base into 2 chilled glasses. Scatter the crushed Oreos over the top and use a long spoon to press them down and fold them through 3 or 4 times, leaving some pieces visible on the surface. Serve immediately, with an extra 2 or 3 Oreo crumbles pressed into the top as a garnish.
Recipe Tips
- Chill your glasses – Pop 2 glasses in the freezer for 10 minutes before you pour. It slows down melting and keeps the texture thick longer.
- Soften the ice cream first – Let the ice cream sit on the counter for 5 minutes before blending. Rock-hard ice cream strains the blender and can leave small lumps.
- Use a hand mixer as an alternative – If you do not have a blender, beat the softened ice cream, milk, cream, and extract with a hand mixer on medium for about 40 seconds. It gets you a very similar texture.
- Scale it up easily – This recipe doubles cleanly. Just keep the ratio of 1/4 tsp peppermint extract per cup of ice cream so the mint does not get overwhelming.
Scale it to your batch size:
| Servings | Vanilla Ice Cream | Milk | Heavy Cream | Peppermint Extract | Oreos |
|---|---|---|---|---|---|
| 2 | 2 cups | 3 tbsp | 2 tbsp | 1/2 tsp | 8 |
| 4 | 4 cups | 6 tbsp | 4 tbsp | 1 tsp | 16 |
| 6 | 6 cups | 9 tbsp | 6 tbsp | 1 1/2 tsp | 24 |
How To Store
- Refrigerate – This is best consumed right away. If you have leftover blended base without the cookies mixed in, cover tightly and freeze for up to 1 day. The texture will be icier after freezing.
- Serve Cold – Re-blend the frozen base for 10 seconds with a splash of milk before serving, then fold in fresh crushed Oreos rather than ones that have been sitting in the mixture.
Frequently Asked Questions
Can I make this without a blender?
Yes. Soften the ice cream for 5 minutes, then beat everything except the Oreos with a hand mixer on medium speed for about 40 seconds until smooth.
Why does my McFlurry taste too strongly of mint?
Peppermint extract is very concentrated. Measure carefully, and if you are sensitive to mint, start with 1/4 tsp and taste before adding more.
Can I use mint chocolate chip ice cream instead of vanilla?
You can, but skip the peppermint extract entirely since mint chip ice cream already carries enough mint flavor on its own.
Does the food coloring change the flavor?
No. It is purely visual. Leave it out entirely if you prefer, and the taste will be identical.
