Instructions
4 steps- 1
Brew 1 cup of strong coffee using your preferred method, aiming for a piping-hot temperature of around 195°F so the fats emulsify smoothly.
- 2
Pour the hot coffee into a blender, then add the 1 tablespoon of grass-fed butter and 1 tablespoon of MCT oil while the liquid is still very hot.
- 3
Secure the lid tightly with a folded towel over the top and blend on high for 20 to 30 seconds, until the mixture turns pale, opaque, and develops a thick foamy crema on top.
- 4
Pour into a warmed mug, dust with a pinch of cinnamon if desired, and drink immediately while frothy, before the fat separates.

Chef notes & practical guide
Technique notes, ingredient swaps, serve-alongside ideas, storage guidance, and equipment for this recipe.
Cultural context
Bulletproof coffee became widely known in North American keto and biohacking circles in the early 2010s as a way to blend coffee with fats into a latte-like morning drink. It is sometimes compared with butter tea traditions from Himalayan regions, but this version is a modern coffee-bar and diet-culture adaptation rather than the same drink.
Listahan note
This version keeps the drink very simple and focuses on the one thing that makes it work: blending hot coffee with the fats long enough to form a creamy emulsion. The cinnamon stays optional so the coffee, butter, and oil remain the main profile.
Technique cues
- Use coffee that is still very hot when it hits the blender; cooler coffee will not hold the fat as smoothly and can taste oily faster.
- Blend until the drink turns pale and opaque, not just until the butter melts. That visual change tells you the fat has dispersed into the coffee.
- Warm the mug first if you can. A cold mug cools the drink quickly, and this style of coffee is best before the foam settles.
Kitchen flow
- Parallel prep
- Warm the mugs with hot tap water while the coffee brews, then dump the water right before pouring.
- Make-ahead
- Do not blend ahead for best texture; measure the butter and oil into the blender cup while the coffee brews.
- Leftover move
- Chill extra coffee, then re-blend it briefly with a splash of fresh hot coffee to loosen the separated fats.
- Cleanup rhythm
- Rinse the blender with hot water right after pouring, before the butter film cools and clings to the jar.
Ingredient brief
Role, handling, and swap guidance for each key ingredient.
Freshly brewed hot coffee
Liquid base
Purpose: Strong hot coffee gives the drink enough bitterness and structure to balance the richness of the butter and oil.
Handling: Brew it fresh and use it immediately while steaming hot.
Adaptation: Espresso diluted with hot water gives a bolder cafe-style base; mild drip coffee makes a softer drink.
Grass-fed unsalted butter
Creamy fat
Purpose: Butter gives the coffee its dairy richness, rounded mouthfeel, and pale latte-like body.
Handling: Cut it into small pieces so it melts quickly in the hot coffee before blending.
Adaptation: Regular unsalted butter works with a similar texture; ghee gives a cleaner butter flavor with less milk-solid taste.
MCT oil (or coconut oil)
Blendable oil
Purpose: MCT oil adds body without the heavier flavor that more butter would bring.
Handling: Measure carefully, especially if you are new to using it, because a little changes the texture quickly.
Adaptation: Coconut oil works as listed, with a more noticeable coconut aroma and a slightly firmer texture as the drink cools.
Ground cinnamon (optional)
Finishing spice
Purpose: Cinnamon adds warmth and a dry, aromatic edge that keeps the drink from tasting flat.
Handling: Dust it over the finished foam rather than blending it in if you want the aroma to stay on top.
Adaptation: A tiny pinch of cocoa powder gives a more mocha-like finish without changing the method.
Technique notes
- Hold the blender lid down with a folded towel because hot liquid expands and can push upward as it blends.
- Start on a lower speed for a second if your blender allows it, then move to high once the butter begins to disappear.
- Drink it right away. As it sits, the foam thins and the fat can rise back to the surface.
Ingredient swaps
- Dairy-free direction
- Replace the butter with refined coconut oil or use extra MCT oil; the drink will be lighter and less creamy, with less of a latte-like finish.
- Gentler richness
- Use half the butter and half the MCT oil the first time, then adjust upward if you like a heavier texture.
- No-blender shortcut
- Use a milk frother in a tall heatproof jar or mug, adding the fats slowly so they disperse instead of floating on top.
Serve alongside
- Soft-scrambled eggs with chives
- Avocado and smoked salmon plate
- Spinach and feta egg bites
- Chia pudding with berries
- Sparkling water with lemon
- Unsweetened iced green tea
- Plain cold brew

Storage & reheating
- Refrigerate leftover blended coffee in a sealed jar for up to 1 day; expect the fat to separate as it chills.
- Reheat gently in a small saucepan or microwave-safe mug, then blend or froth again to bring back the creamy texture.
- Freezing is not worthwhile for this drink; the emulsion breaks and the reheated texture turns grainy.
Equipment
- Coffee maker or kettle setup
- Heatproof blender
- Folded kitchen towel
- Warmed mugs
