Forget sugary iced lattes from the café. Today, we’re upgrading your cold brew game with a delicious, healthy, and satisfying cold brew bulletproof coffee recipe that’s as easy to make as it is transformative.
This recipe blends the bold richness of cold brew coffee with the creamy, satiating power of grass-fed butter and MCT oil—plus a touch of natural sweetness and spice for a latte-like experience that fuels your body and your day.
And yes—it’s 100% keto-approved, dairy-sensitive friendly (with a simple swap!), and ready in under 5 minutes.
🌱 Why Cold Brew + Bulletproof = The Ultimate Morning Combo
Before we dive into the step-by-step, let’s talk why this combo works so well—especially if you’re into clean eating, weight management, or cognitive performance.
✅ Cold Brew Coffee: Smooth, Low-Acid, and Caffeine-Rich
Cold brew is made by steeping coarsely ground coffee in cold water for 12–24 hours. The result? A less acidic, naturally sweeter, and smoother coffee concentrate that’s easier on your stomach—perfect for sensitive digestive systems (like mine!).
It also has higher caffeine content than regular drip coffee, giving you a clean, jitter-free energy lift that lasts.
✅ Bulletproof Ingredients: Fat for Fuel
Traditional bulletproof coffee (popularized by Dave Asprey) uses grass-fed butter and MCT oil blended into hot coffee to create a creamy, high-fat drink that supports ketosis, suppresses appetite, and sharpens mental clarity.
But what if you prefer iced coffee? That’s where this cold brew bulletproof coffee recipe shines—it brings those same metabolic and cognitive benefits into a refreshing, cool format perfect for summer mornings or warm climates.
🛒 Ingredients You’ll Need
Here’s everything you need to make one serving of this keto-friendly cold brew bulletproof latte:

| Grass-fed unsalted butter(1 tbsp) | Rich in butyrate, omega-3s, CLA | Usegrass-fed gheeif lactose intolerant |
| MCT oil(½–1 tsp to start) | Fast-burning fat for energy & focus | Start small to avoid digestive upset |
| Vanilla bean powder(¼ tsp) | Natural flavor + anti-inflammatory | Vanilla extract (alcohol-free preferred) |

👩🍳 Step-by-Step Instructions
Follow these simple steps to make your cold brew bulletproof coffee without a blender or fancy tools.
Step 1: Prepare Your Mug (Not the Serving Glass!)
Grab a heat-safe mug or small bowl—not the glass you’ll serve in. This is crucial!
Why? Because you’ll be mixing hot water with your fats and powders first to emulsify them properly. Pouring cold brew directly over ice after mixing ensures the best texture and flavor.
Step 2: Add the Fats & Powders
Into your mug, add:
- 1 tbsp grass-fed butter (or ghee)
- ½ tsp MCT oil (start low if you’re new!)
- ¼ tsp vanilla bean powder
- A pinch of Ceylon cinnamon
- Monk fruit sweetener to taste (start with ¼ tsp)
⚠️ Important: Don’t skip the hot water step! Cold liquids won’t melt the butter or blend the MCT oil properly, leading to a greasy or separated drink.
Step 3: Pour in Hot Water & Froth
Add 2–3 tablespoons of hot (not boiling) water to the mug.
Now, froth the mixture using one of these methods:
- Handheld milk frother (my favorite—quiet, fast, easy to clean)
- Blender (blend 15–20 seconds until creamy)
- Jar + tight lid (shake vigorously for 30 seconds)
You should see a creamy, latte-like foam forming—this is your “bulletproof base.”
Step 4: Slowly Add Cold Brew
While frothing (or blending), gradually pour in 1 cup of chilled cold brew.
This gradual incorporation helps emulsify the fats into the coffee—no separation, no oily slick on top.
🌟 Sarah’s Tip: If using a blender, pour cold brew in through the lid opening while it’s running. If using a frother, just keep frothing as you pour.
Step 5: Serve Over Ice
Fill a tall glass with fresh ice cubes.
Pour your creamy cold brew mixture over the ice.
Watch it cascade into a velvety, frothy, café-quality latte—but with zero sugar and 100% clean energy.
Step 6: Enjoy Mindfully
Sip slowly. Feel the calm alertness. Notice how your stomach stays full for hours.
This isn’t just coffee—it’s your morning metabolic boost.
💡 Pro Tips for Perfect Results Every Time
- Make Cold Brew in Bulk
Brew a large batch weekly (1:4 coffee-to-water ratio, steep 16 hours). Store in the fridge for up to 2 weeks. Dilute with water or milk if too strong. - MCT Oil Adjustment
New to MCT oil? Start with ¼–½ tsp. Gradually increase to 1 tsp over 1–2 weeks to avoid digestive discomfort. - Dairy-Free Option
Use clarified grass-fed ghee—it’s virtually lactose-free but still delivers butyrate and healthy fats. - Flavor Variations
- Add cacao powder for mocha vibes
- Swap vanilla for almond extract
- Sprinkle sea salt for a “salted caramel” twist
- On-the-Go Version
Pre-mix dry ingredients (cinnamon, monk fruit, vanilla) in a small container. At work? Just add to cold brew + MCT oil + shake!
🧠 Health Benefits: More Than Just a Tasty Drink
This isn’t just a trendy coffee hack—it’s a functional wellness ritual with science-backed perks:
🔥 Supports Ketosis & Fat Burning
The medium-chain triglycerides (MCTs) in MCT oil are rapidly converted into ketones—your brain’s preferred fuel during ketosis. Combined with grass-fed butter’s CLA, this drink helps maintain a fat-burning state.
⚖️ Stabilizes Blood Sugar
No sugar crash here! Healthy fats + cinnamon help slow glucose absorption, preventing energy dips and sugar cravings later.
🧠 Boosts Mental Clarity
Ketones from MCTs cross the blood-brain barrier quickly, enhancing focus, memory, and cognitive stamina—ideal for work-from-home days or intense study sessions.
🌿 Anti-Inflammatory & Gut-Supportive
Butyrate (from grass-fed butter) nourishes gut lining cells, while cinnamon and vanilla offer potent anti-inflammatory and antioxidant compounds.
❓ FAQs: Your Top Questions Answered
Q: Can I use regular butter instead of grass-fed?
A: You can, but you’ll miss out on higher omega-3s, CLA, and butyrate. Grass-fed is worth the upgrade for maximum benefits.
Q: Is this drink keto-friendly?
A: Absolutely! With <1g net carbs (depending on sweetener), it fits perfectly into a ketogenic or low-carb lifestyle.
Q: Can I make this ahead of time?
A: Not recommended. The fats may separate when refrigerated. Best made fresh—but it only takes 3 minutes!
Q: What if I don’t have a frother or blender?
A: Use a small jar with a tight lid. Add hot water + ingredients, shake hard for 30 seconds, then pour in cold brew and shake again.
Q: Can I add milk or cream?
A: Yes—but choose unsweetened almond, coconut, or macadamia milk to keep it keto. Avoid dairy milk if tracking carbs closely.
🌈 Final Thoughts: Your New Morning Staple
As someone who’s always on the go—recording videos, editing, managing affiliate content, and juggling wellness goals—I need a morning routine that’s simple, satisfying, and sustainable. This cold brew bulletproof coffee checks every box.
