Ingredients You’ll Need

Ingredient (yes, the didactic part — simple and direct):

• 2 cups vanilla ice cream
• 1/2 cup milk
• 1/2 cup crushed Oreo cookies (use more if you’re feeling savage)
• 1/4 teaspoon peppermint extract
• Green food coloring (optional)

I keep things straightforward because complexity belongs in soufflés, not McFlurries. FYI: use full-fat ice cream for better texture and flavor.

How to Make (Step-by-Step)

Method (short, sweet, effective):

Step 1 — Prep your cookies and ice cream

Crush the Oreos in a zip-top bag with a rolling pin or pulse them a couple seconds in a food processor. Scoop the vanilla ice cream into your blender-ready bowl and let it soften for about a minute so it blends smoothly.

Step 2 — Blend the base

In a blender, combine the vanilla ice cream, milk, peppermint extract, and a few drops of green food coloring if desired. Blend until smooth. Keep an eye on the texture — you want it thick, not milkshake-thin.

Step 3 — Add the crunch

Stir in the crushed Oreo cookies. Don’t blend these in unless you want a uniform gray-green slush; we want visible cookie chunks.

Step 4 — Serve immediately

Spoon into a cup, napkin optional but recommended, and enjoy this minty treat! Top it or don’t; it still slaps either way.

Pro Tips for the Best Results

• Use slightly softened ice cream: Let it sit for 30–60 seconds so your blender doesn’t overwork and warm the mixture.
• Choose quality peppermint extract: A little high-quality extract goes a long way. Cheap ones taste medicinal.
• Add milk incrementally: Start with 1/2 cup and add a tablespoon at a time if you want a looser texture.
• Don’t over-blend Oreos: Stir them in to keep crunchy chunks. Texture matters.
• Adjust sweetness: If your ice cream tastes super sweet, cut the peppermint to 1/8 teaspoon.
• Serve cold bowls: Chill your serving glasses in the freezer for a frosty presentation.

Fun Variations & Topping Ideas

Variations:

• Double Oreo: Swap crushed Oreos with Oreo Thins for extra crispiness.
• Chocolate-mint: Add 1 tablespoon of chocolate syrup in the blender for a mocha-mint vibe.
• Vegan shamrock: Use a plant-based vanilla ice cream and almond milk; still delightful.
• Adult twist: Stir in 1 tablespoon of crème de menthe or mint liqueur after blending (keep it responsible).

Toppings:

• Whipped cream and extra cookie crumbs
• Mini chocolate chips or shavings
• Crushed peppermint candies for extra mint crunch
• A drizzle of hot fudge if you want to be extra dramatic

Storing and Reheating

Okay, let’s address the obvious: McFlurries don’t reheat like pizza. Here’s how to handle leftovers like a pro.

• Storing: Transfer leftover McFlurry into an airtight container. Press parchment paper against the surface to prevent ice crystals. Freeze for up to 2 weeks.
• Thawing: Remove the container from the freezer and sit it in the fridge for 10–15 minutes before scooping. This keeps texture closest to fresh.
• Re-serving: If the dessert gets too hard, microwave a small scoop for 6–10 seconds and stir. Don’t microwave the whole container unless you’re okay with a melted soup.
• Freshen up: Stir in a splash of milk and another tiny pinch of peppermint extract if the mint fades after freezing.

Frequently Asked Questions (FAQ)

How can I make this less minty?

Use 1/8 teaspoon peppermint extract or omit it entirely and add a drop of mint syrup instead for a milder flavor.

Can I use milkshake ice cream instead of regular vanilla?

Yes. Use any creamy vanilla as your base. Just watch the sugar level — some premade milkshakes make the whole thing too sweet.

Will blending ruin the Oreo chunks?

Blending will pulverize them if you mix them in. Stir Oreos in by hand to preserve big crunchy bites.

Can I use peppermint oil?

I don’t recommend peppermint oil for this because it concentrates flavor and can overpower. Stick to food-grade peppermint extract.

Is green food coloring necessary?

Nope. The classic minty vibe works without coloring. Use green dye only if presentation matters to you.
