Ingredients Method

Ingredients

  

• 1 frozen banana, sliced
• 1 cup milk of choice (dairy, almond, oat, or cashew)
• 1/2 cup plain or vanilla Greek yogurt (or a dairy-free yogurt)
• 2 tablespoons unsweetened cocoa powder
• 1–2 teaspoons pure maple syrup or honey, to taste (optional)
• 1/4 teaspoon peppermint extract (not mint extract; see notes)
• 1/2 teaspoon vanilla extract
• 1 handful fresh spinach (optional, for color and nutrients)
• 1–2 tablespoons chocolate chips or cacao nibs (optional, for texture)
• 1 cup ice (adjust for thickness)
• Pinch of sea salt (optional, to deepen the chocolate flavor)

Method

 

1. Prep your base: Add the milk, yogurt, and frozen banana to the blender. Starting with liquids helps everything blend smoothly.
2. Add flavor: Sprinkle in the cocoa powder, vanilla, peppermint extract, and a pinch of salt. If using sweetener, add 1 teaspoon to start.
3. Boost it: Toss in the spinach if you want a nutrient bump and a subtle green hue. Add chocolate chips or cacao nibs if you like a cookie-like bite.
4. Chill factor: Add the ice. Use more for a thicker, shake-like texture, less if you want it sippable.
5. Blend: Start on low, then increase to high until completely smooth, 30–60 seconds. If it’s too thick, splash in more milk.
6. Taste and adjust: Add a little more maple syrup or peppermint extract if needed. A tiny bit of mint goes a long way, so add carefully.
7. Serve: Pour into a chilled glass. For fun, garnish with a sprinkle of cocoa, a few nibs, or a fresh mint leaf.

What Makes This Special

This smoothie tastes like a milkshake, but it’s built with nourishing ingredients that help you feel full and satisfied. Cocoa, mint, and vanilla bring big flavor, while banana and yogurt create a smooth, creamy texture.

You can customize it based on what you have: dairy or non-dairy, sweetened or no added sugar. It’s also easy to make thicker for a bowl or thinner for a quick sip. And yes—it really does remind you of that classic cookie.

How to Store

This smoothie is best fresh, but you can keep it in a sealed jar in the fridge for up to 24 hours. The texture may thicken or separate—just shake or blend again with a splash of milk. For make-ahead convenience, freeze smoothie packs: portion banana slices, spinach, cocoa, and chocolate chips in a bag, then add liquids and blend when ready.

You can also freeze leftovers in popsicle molds for a quick, cool treat.

Why This is Good for You

• Protein and staying power: Greek yogurt adds protein, which helps keep you full and supports muscle repair.
• Fiber and potassium: Banana offers natural sweetness, potassium for heart health, and fiber for digestion.
• Antioxidants: Unsweetened cocoa powder contains flavonoids that support overall wellness and may help reduce inflammation.
• Greens, made easy: Spinach blends right in and brings iron, folate, and vitamins A and C, without changing the taste much.
• Lower sugar option: You control the sweetness. Skip added sweeteners or choose a small drizzle for balance.

Pitfalls to Watch Out For

• Overdoing the mint: Peppermint extract is strong. Start with 1/4 teaspoon and add drop by drop to avoid a toothpaste vibe.
• Too much ice: Excess ice can water down the chocolate flavor.

  Balance thickness with frozen banana instead of only ice.

• Sweetness creep: If your yogurt is already sweetened, taste before adding maple syrup. It’s easy to oversweeten.
• Cocoa clumps: Add cocoa after liquids and blend well to avoid dry pockets. A quick stir before blending helps.
• Thin texture: If it pours too quickly, add a few more banana slices, extra yogurt, or a small handful of oats to thicken.

Variations You Can Try

• High-Protein: Add a scoop of chocolate or vanilla protein powder and reduce sweetener.

  If it thickens too much, add more milk.

• Dairy-Free: Use almond or oat milk and a coconut or almond milk yogurt. The coconut version adds a subtle cookie-and-cream vibe.
• Mocha Mint: Add 1–2 teaspoons instant espresso powder or replace some milk with chilled coffee for a caffeinated twist.
• Cookie Crunch: Blend as usual, then pulse in a small handful of chocolate wafer crumbs for a true Thin Mint nod.
• Nutty Mint: Add 1 tablespoon almond butter or cashew butter for richness and extra staying power.
• Green Glow: Add 1/4 avocado for creaminess and healthy fats; cut back slightly on yogurt to keep balance.
• Low-Carb Lean: Swap banana for 1/2 avocado and a few ice cubes; sweeten lightly with a zero-calorie sweetener if desired.

FAQ

Can I use mint leaves instead of peppermint extract?

Yes. Use a small handful of fresh mint leaves, but note the flavor will be gentler and more herbal.

If you want that classic Thin Mint punch, a few drops of peppermint extract alongside leaves works best.

Is there a difference between peppermint extract and mint extract?

There is. Mint extract often blends spearmint and peppermint, which can taste more grassy or mild. Peppermint extract delivers that cool, sharp flavor you associate with Thin Mint cookies.

How can I make it thicker like a shake?

Use a fully frozen banana, reduce the milk slightly, and add more ice or a bit of yogurt. You can also blend in 2–3 tablespoons of rolled oats and let it sit for a minute to thicken naturally.

What if I don’t have cocoa powder?

You can use chocolate protein powder or a tablespoon of melted dark chocolate.

If using melted chocolate, blend quickly and add it while the blender is running so it doesn’t seize.

Can kids drink this?

Absolutely. Keep the mint extract on the lighter side and skip any added caffeine. If you’re using sweetened yogurt or milk, you might not need extra sweetener at all.

How do I make it without banana?

Use 1/2 avocado for creaminess and a few ice cubes for chill.

Add a touch more sweetener to balance the cocoa since you’re removing banana’s natural sweetness.

Will the spinach change the taste?

Not much. Spinach is mild and mostly adds color and nutrients. If you’re sensitive to greens, start with a small handful and increase as you get used to it.

Can I meal-prep this for the week?

You can prep freezer packs with banana, spinach, cocoa, and chocolate chips.

In the morning, add milk, yogurt, and extracts, then blend. This keeps flavors fresh and the texture spot-on.

In Conclusion

The Thin Mint Smoothie is a simple way to enjoy that nostalgic mint-chocolate flavor with ingredients you can feel good about. It’s creamy, cool, and endlessly adaptable—perfect for breakfast, a snack, or a light dessert.

Keep the mint balanced, the cocoa rich, and the sweetness just right for your taste. Once you get your favorite ratio, it’ll become a regular in your blender rotation.
