Best Coffee for Bulletproof Coffee
Bulletproof coffee blends black coffee with butter and MCT oil - a strong, clean-tasting base matters more here than usual. Here's what to use.

Bulletproof coffee is black coffee blended (not just stirred) with a fat - traditionally grass-fed butter or ghee - and a source of MCT (medium-chain triglyceride) oil or coconut oil, until it turns frothy and almost latte-like. It was popularised as a breakfast replacement, especially by people doing intermittent fasting or a ketogenic-style diet, since it adds fat and satiety without the carbs of a regular breakfast.
Why the Base Coffee Matters More Here
In a regular cup, milk and sugar cover up a lot of flaws in the coffee. In bulletproof coffee, butter and oil don't mask bitterness the same way - they add richness, but a harsh, over-extracted, or stale coffee still tastes harsh underneath the fat. Because of that, you want a base coffee that's:
- Strong - brewed a bit more concentrated than usual, since it's about to be diluted in flavour (if not volume) by the fat.
- Clean and low-bitterness - a good medium-to-dark roast without a burnt or ashy edge holds up much better blended than a very light, sharp roast.
- Fresh - stale coffee's flat, cardboard-y notes get more noticeable once you're drinking it slowly, without milk to hide it.
A Simple Recipe
- Brew roughly 1.5-2 cups of strong black coffee (French press or filter both work well).
- Add 1-2 tablespoons of unsalted grass-fed butter or ghee.
- Add 1 teaspoon to 1 tablespoon of MCT oil or coconut oil - start low if you're new to it, since MCT oil can cause stomach upset in larger amounts.
- Blend for 20-30 seconds in a regular blender until frothy and emulsified - a spoon or whisk won't fully combine the fat, you'll just get an oil slick on top.
Pour hot and drink it fresh; it separates again if it sits too long.
Is It Right for You?
Bulletproof coffee is calorie-dense - a tablespoon each of butter and MCT oil adds roughly 200-250 calories, mostly saturated and MCT fat. That can be useful if your goal is appetite control during a fast or extra fuel on a low-carb plan, but it isn't automatically a "healthy" addition for everyone, and it doesn't suit every diet goal. This isn't medical or nutrition advice - if you're using it as part of an intermittent fasting or ketogenic protocol, it's worth checking the approach with a doctor or nutritionist first.

For bulletproof coffee, skip the delicate single-origin light roast and reach for something bold and clean - the fat will do plenty of work on texture, the coffee just needs to hold its own underneath it.
