Ingredients:

1 cup hot brewed coffee (your favorite variety)
1 tablespoon grass-fed butter (or ghee or coconut oil)
1 tablespoon MCT oil (C8/C10 blend recommended)
Optional:
- 1 scoop collagen peptides
- 1-2 tablespoons unsweetened almond milk or keto creamer
- 1 teaspoon sugar-free sweetener (e.g., monk fruit/allulose blend)
- Dash of cinnamon, cocoa powder, or turmeric for flavor
- Sugar-free whipped cream or syrup drizzle for topping

Instructions:

Brew your coffee and pour it into a blender or tall mug.
Add butter and MCT oil (plus any optional ingredients).
Blend using one of the following methods:
- Blender: Secure lid and blend for 20–30 seconds until frothy.
- Milk frother or immersion blender: Mix directly in your mug.
- Self-stirring mug: Add ingredients and stir with the built-in motor.
Pour into a mug (if not already in one). Enjoy immediately for best texture.

Pro Tip:
Drink your bulletproof coffee fresh — once it cools, the fats may separate. If needed, re-blend for a quick refresh.

Ingredients for Bulletproof Coffee

The magic of bulletproof coffee lies in how a few high-quality ingredients come together to create a rich, frothy powerhouse of a drink. Here’s what you need — plus some flexible options depending on your dietary goals.

Core Ingredients

Hot Brewed Coffee – Use any style you enjoy: drip, French press, Americano, or even instant. For best flavor, go with a medium-dark roast. Decaf works too.
Grass-Fed Butter – Not just any butter. Grass-fed butter (like Kerrygold) is richer in omega-3s and fat-soluble vitamins. Ghee is a good lactose-free substitute.
MCT Oil – Medium-chain triglycerides are the secret weapon for quick energy. Go for a C8/C10 blend for optimal cognitive and metabolic effects.

Why these? When blended, the fat molecules emulsify into the coffee, creating a latte-like texture without dairy or sugar — ideal for keto or fasting.

Optional Add-Ins (Customizable Perks)

Unsweetened Almond Milk or Keto Creamer – Lightens the texture while keeping it low-carb.
Collagen Peptides – Adds protein and supports skin, joint, and gut health.
Monk Fruit or Allulose Sweetener – Balances bitterness with a clean sweetness.
Spices – Try cinnamon, turmeric, or a dash of cayenne for a health kick.
Unsweetened Cocoa Powder – Turns it into a keto mocha.
Toppings – Sugar-free whipped cream, keto syrups (vanilla, hazelnut, caramel), or even a sprinkle of salt for balance.

Can I use coconut oil instead of MCT oil?

Yes, but with some caveats. Coconut oil has MCTs in it but also includes C12 (lauric acid), which is slower to absorb. It works for texture, but you’ll miss the quick-energy boost of pure MCT oil. Also, coconut oil has a more distinct flavor that may overpower your coffee.

How to Make Bulletproof Coffee (3 Easy Ways)

Making bulletproof coffee the right way is all about emulsification. Simply stirring in oil and butter won’t cut it — you’ll end up with a greasy puddle on top. Instead, use one of these three proven methods to create a frothy, satisfying drink that tastes like a real latte (minus the carbs).

Step-by-Step Instructions

Brew the Coffee
Start with 1 cup of hot coffee. Any brewing method works: drip, French press, pour-over, or espresso diluted into an Americano. Just make sure it’s piping hot — you want enough heat to melt and blend the fats.
Add Ingredients
Into your blender, mug, or stirring vessel, add:
- 1 tablespoon grass-fed butter (or ghee/coconut oil)
- 1 tablespoon MCT oil
- Any optional add-ins: sweetener, collagen, almond milk, etc.
Blend Until Frothy
Choose your blending method:
- Blender (Best Texture)
  Add all ingredients, secure the lid, and blend on high for 20–30 seconds. You’ll get a creamy, café-style froth.
- Milk Frother or Immersion Blender
  Place everything in a tall mug and use the frother to emulsify. Be careful — don’t overfill the cup, or it might splash.
- Self-Stirring Mug (On-the-Go Option)
  Perfect for minimal cleanup. Just add the ingredients, press the button, and let the mug do the work.
Serve and Enjoy Immediately
Pour into your favorite mug (if not already there). Drink right away while it’s hot and emulsified.

What if my bulletproof coffee separates?

That’s normal if it sits too long. Just re-blend or use a frother to bring it back. To prevent this, drink it while it’s still hot and fresh. You can also add a bit of lecithin powder or collagen to help stabilize the emulsion.

Tips & Tricks for the Perfect Bulletproof Coffee

Making bulletproof coffee isn’t complicated — but like anything, the difference between “meh” and “mind-blowing” comes down to a few small details. Whether you’re just starting or you’ve been blending butter into your brew for years, these tricks will take your morning cup to the next level.

Froth Is Everything

Use hot coffee: Not warm. Not lukewarm. Hot. This helps melt the fats and makes it easier to emulsify everything into that creamy, latte-like texture.
Blend, don’t stir: Stirring will leave oil floating on top. Always use a blender, milk frother, or self-stirring mug. The goal is to create a consistent, velvety texture.
Start slow, then ramp up: When using a high-speed blender, pulse first before going full speed. This prevents splashes and ensures even blending.

Texture + Flavor Tweaks

Add a pinch of salt: Sounds weird, but it enhances flavor and reduces bitterness.
Sweeten smartly: If you’re used to sweet lattes, ease into it. Try a bit of monk fruit/allulose blend or a keto vanilla syrup.
Collagen = creamy boost: Not just for protein — collagen helps emulsify fats better, giving you more froth and less separation.

Mind the Timing

Drink it fresh: Let’s be real — re-heated butter coffee tastes… off. Drink it while it’s hot and freshly blended.
Meal prep tip: You can pre-measure your butter and MCT oil into silicone molds or an ice cube tray, freeze, and pop one into your blender with fresh coffee each morning.

How can I make bulletproof coffee creamier?

Use a combo of butter and MCT oil — both are needed for texture. For extra creaminess, blend in a tablespoon of unsweetened almond milk or a keto-friendly creamer. Collagen peptides and a longer blend time also help create a thicker, frothier drink.

Substitutions & Variations for Bulletproof Coffee

Bulletproof coffee isn’t a one-size-fits-all situation. Whether you’re dairy-free, experimenting with flavors, or just craving something different, here are some of the best ways to mix it up — without sacrificing the benefits.

Dairy-Free or Vegan Swaps

Ghee – A lactose-free alternative to butter that still delivers creaminess and rich flavor.
Coconut Oil – A solid stand-in for MCT oil. You’ll still get some MCTs, just with a gentler energy boost.
Vegan Butter – Works if you’re avoiding all animal products, but check for added carbs or oils that aren’t keto-friendly.

Flavor Variations You’ll Actually Want

Keto Mocha – Add 1–2 tablespoons unsweetened cocoa powder + your favorite keto sweetener. Bonus: it masks any lingering bitterness from strong coffee.
Spiced Up – Cinnamon, turmeric, or even pumpkin pie spice. Perfect in fall or for a subtle wellness boost.
Iced Bulletproof Coffee – Make it hot, blend, then pour over ice. Drink quickly — the fats will separate if it sits.
Salted Caramel or Hazelnut Latte Vibes – Add a splash of sugar-free flavored syrup (vanilla, hazelnut, caramel). These keto options sweeten without spiking your blood sugar.
Protein Boosted – Add a scoop of collagen or keto-friendly protein powder to turn your drink into a full breakfast substitute.

Can I make bulletproof coffee without butter?

Absolutely. You can substitute coconut oil, ghee, or a dairy-free creamer. However, butter gives the drink a unique richness and a true latte-like mouthfeel. Without it, the drink may feel thinner or separate more quickly unless you add something like collagen to help emulsify.

Frequently Asked Questions About Bulletproof Coffee

Does bulletproof coffee break a fast?

Technically, yes — it contains calories, so it breaks a “pure” fast. But for many doing intermittent fasting, the fat-only profile doesn’t spike insulin or kick you out of ketosis. It’s called a “fat fast” by some and can still deliver benefits like mental clarity, appetite suppression, and stable energy.

Can I make bulletproof coffee with tea?

Yes! Use a strong black tea or chai as your base instead of coffee. Blend with butter and MCT oil the same way. It won’t have quite the same richness, but it works well if you’re caffeine-sensitive or just not a coffee fan. Try it with Earl Grey for a creamy keto “London fog.”

Can I make it ahead of time?

Sort of. Bulletproof coffee separates quickly as it cools — it’s just the nature of blending fats with liquid. You can pre-mix your fats in a jar and refrigerate or freeze in cubes. When ready, brew fresh coffee and blend in one of the cubes. Fresh blending = best froth.

Is it safe to drink bulletproof coffee every day?

For most people, yes — assuming you’re not overdoing it on total daily fats or skipping real food entirely. If you’re using it as a breakfast replacement, make sure you’re still getting fiber and micronutrients later in the day. And if you’re sensitive to fats or caffeine, start slow.

What’s the best time of day to drink it?

Morning is ideal. The MCT oil gives an immediate energy boost and mental clarity, making it perfect as a breakfast replacement or pre-work session drink. Avoid late afternoon or evening if caffeine keeps you up.

Nutrition Information for Bulletproof Coffee

Understanding the macros in your bulletproof coffee can help you stay on track, especially if you’re tracking for keto, intermittent fasting, or general low-carb living. Here’s a breakdown of what’s typically in one serving, depending on your exact ingredients.

Macronutrient Notes

All fat, no carbs: This drink is designed to provide clean energy from fats without disrupting ketosis.

Is bulletproof coffee actually good for you?

It can be — if used intentionally. It’s high in healthy fats and can keep you full, focused, and in ketosis. But it’s not a miracle drink. Make sure you’re getting enough fiber, protein, and micronutrients throughout the day if you’re skipping breakfast in favor of bulletproof coffee regularly.
