Equipment
Method
- Brew one cup of coffee using your preferred method. French press or pour-over produce the cleanest flavour base. The coffee should be hot — just off the boil — when it goes into the blender.
- Add the grass-fed butter and MCT oil to the blender first. Pour the hot coffee over the top. Never add the butter directly to the coffee in a mug and stir — the fat will float on the surface rather than emulsifying.
- Blend on high for 20–30 seconds until the mixture turns creamy and frothy with a uniform colour. It should look like a latte, not like oily coffee. An immersion blender works well if you don’t want to use a full blender for a single cup.
- Pour into a mug and serve immediately. Bulletproof coffee separates as it cools — drink it hot for the best texture. Do not reheat once made.
Nutrition
Notes
Net carbs: 0g per serving. Bulletproof coffee contains no carbohydrates and will not raise blood sugar or disrupt ketosis.
Start low on MCT oil: If you are new to MCT oil, begin with 1 teaspoon and increase to 1 tablespoon over 1–2 weeks. Too much too soon commonly causes bloating and digestive upset.
The blender is essential: Stirring will not emulsify the fat. You need mechanical blending — even 20 seconds with an immersion blender makes a significant difference in texture and drinkability.
Grass-fed butter matters: Grass-fed butter has a higher omega-3 and conjugated linoleic acid (CLA) content than conventional butter. Kerrygold is the standard choice in Canada and widely available.
Intermittent fasting use: Most fasting protocols allow bulletproof coffee during the fasting window because it contains no carbs or protein. It extends the fasting window comfortably for most people. If you are fasting for metabolic or autophagy reasons, check with your healthcare provider.
Calorie note: This recipe as written is approximately 225 calories. Using 2 tbsp butter and 2 tbsp MCT oil brings the total to approximately 450 calories — appropriate as a full meal replacement, not an addition to breakfast.
