What to check first

Brewer type and filter type

Your coffee maker’s type and the filter you use will influence the final taste and texture of your base coffee. Drip coffee makers with paper filters tend to produce a cleaner cup, while French presses or pour-overs with metal filters allow more oils and sediment through, which can contribute to a richer mouthfeel. For bulletproof coffee, a clean, strong brew is generally preferred.

Water quality and temperature

The quality of your water significantly impacts coffee flavor. If your tap water has a strong taste or odor, consider using filtered water. For bulletproof coffee, the water should be hot enough to melt the butter and emulsify the oils, typically between 195°F and 205°F. Water that is too cool won’t properly blend, while boiling water can scorch the coffee grounds.

Grind size and coffee freshness

The grind size should be appropriate for your brewing method. For drip coffee, a medium grind is common. Freshly roasted and ground coffee beans will yield the most vibrant flavor. Stale coffee can result in a flat, uninspired base for your bulletproof concoction. Aim to grind your beans just before brewing.

Coffee-to-water ratio

A common starting point for a strong coffee base is a ratio of 1:15 to 1:18 (coffee to water by weight). For example, you might use 2 tablespoons of coffee grounds for every 6 ounces of water. Adjusting this ratio can make your coffee stronger or weaker, impacting the overall intensity of the bulletproof drink.

Cleanliness/descale status

A clean brewing apparatus and blender are crucial for good-tasting coffee. Mineral buildup from hard water can affect the taste of your coffee and the performance of your brewer. Regularly descaling your coffee maker and ensuring your Ninja blender is free of old coffee residue will prevent off-flavors and ensure proper blending.

Step-by-step (brew workflow)

1. Brew your coffee.

• What to do: Prepare your coffee as you normally would using your preferred brewing method. Aim for a strong, hot brew.
• What “good” looks like: A hot, flavorful cup of coffee, brewed to your liking.
• Common mistake: Brewing weak coffee. This will result in a diluted bulletproof coffee that lacks depth. Avoid this by using a slightly higher coffee-to-water ratio or a finer grind if your brewer allows.

2. Gather your ingredients.

• What to do: Have your hot coffee, unsalted grass-fed butter (or ghee), and MCT oil ready.
• What “good” looks like: All necessary components are measured and within easy reach.
• Common mistake: Not having ingredients measured out. This can lead to rushing the blending process or adding ingredients inconsistently. Measure everything beforehand.

Have your hot coffee, unsalted grass-fed butter (or ghee), and MCT oil ready. For the best results, we recommend using high-quality grass-fed butter like this option.

3. Add coffee to the Ninja blender.

• What to do: Carefully pour your hot, freshly brewed coffee into the Ninja blender jar.
• What “good” looks like: The blender jar contains the hot coffee, and the liquid level is well below the maximum fill line.
• Common mistake: Overfilling the blender jar. This can cause hot liquid to escape during blending, posing a burn risk. Always leave ample headspace.

4. Add butter.

• What to do: Add 1-2 tablespoons of unsalted grass-fed butter or ghee to the coffee in the blender.
• What “good” looks like: The butter is in the blender jar, ready to be incorporated.
• Common mistake: Using salted butter. This will make your bulletproof coffee unpleasantly salty. Stick to unsalted.

5. Add MCT oil.

• What to do: Add 1-2 tablespoons of MCT oil to the blender jar.
• What “good” looks like: The MCT oil is added alongside the coffee and butter.
• Common mistake: Adding too much MCT oil at once. This can cause digestive upset for some individuals. Start with a smaller amount and increase gradually as tolerated.

6. Secure the lid.

• What to do: Ensure the lid of your Ninja blender is securely fastened. If your model has a vented lid, make sure the vent is properly sealed or covered if instructed.
• What “good” looks like: The lid is firmly in place, creating a seal.
• Common mistake: Not securing the lid properly. This is a major safety hazard, as hot liquids can splash out, causing burns. Double-check the lid’s connection.

7. Blend on high speed.

• What to do: Start the Ninja blender on a low speed, then quickly increase to high speed. Blend for 30-60 seconds.
• What “good” looks like: The mixture is rapidly swirling and becoming frothy and emulsified, with no visible separation of oil or butter.
• Common mistake: Blending for too short a time. This results in an oily, separated drink. Blend until it achieves a latte-like consistency.

8. Check for emulsification.

• What to do: Stop the blender and visually inspect the mixture.
• What “good” looks like: The coffee, butter, and oil have combined into a smooth, creamy, opaque liquid with a frothy top.
• Common mistake: Stopping too soon. If you see oil on top or streaks of unblended butter, it needs more blending.

9. Pour and serve immediately.

• What to do: Carefully pour the blended bulletproof coffee into your mug.
• What “good” looks like: A hot, creamy beverage that holds its frothy texture for a short while.
• Common mistake: Letting it sit too long. The emulsification is temporary, and the drink will start to separate if left to stand. Enjoy it right away.

10. Clean the blender.

• What to do: Rinse the blender jar and lid immediately with warm water. For a more thorough clean, add a drop of dish soap and some warm water, then blend briefly before rinsing.
• What “good” looks like: The blender jar is clean and free of any coffee or oil residue.
• Common mistake: Delaying cleaning. Dried coffee and oil residue can be difficult to remove and can affect future blends. Clean it right after you finish your drink.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your Ninja blender is not rated for hot liquids, then do not attempt to make bulletproof coffee in it because it can cause damage or a safety hazard.
• If you experience digestive upset after drinking bulletproof coffee, then reduce the amount of MCT oil in your next brew because too much can be difficult for some to digest.
• If your bulletproof coffee looks oily and separated, then blend it for longer because it hasn’t fully emulsified yet.
• If your coffee tastes weak, then increase the amount of coffee grounds or use a finer grind in your next brew because the base coffee needs to be stronger.
• If you notice a salty taste, then check that you used unsalted butter because salted butter will make the drink unpalatable.
• If your blender lid feels loose, then stop blending and re-secure it because a proper seal is critical for safety.
• If the butter is not melting into the coffee, then your coffee is likely not hot enough because hot liquid is needed to melt and emulsify the fats.
• If you want a creamier texture, then blend for a slightly longer duration because extended blending helps create a more stable emulsion.
• If you are new to bulletproof coffee, then start with smaller amounts of butter and MCT oil because your body may need time to adjust to the increased fat intake.
• If your coffee has an off-flavor, then ensure your coffee maker and blender are clean because residual oils and mineral buildup can affect taste.
• If the blended coffee is not frothy, then ensure you are blending on the highest speed setting because sufficient speed is needed to incorporate air and create foam.
• If you notice sediment in your cup, then ensure your coffee was brewed with a filter that removes fine particles because some brewing methods allow more sediment through.

FAQ

Can I use regular butter in my Ninja blender for bulletproof coffee?

While you can, it’s recommended to use unsalted grass-fed butter or ghee. Regular salted butter will make your bulletproof coffee taste salty, and grass-fed butter often has a richer flavor and better nutrient profile.

What kind of coffee should I use?

Use a high-quality, freshly roasted coffee bean. The type of roast (light, medium, or dark) is a matter of personal preference, but aim for a strong brew that will stand up to the added fats.

How much MCT oil should I use?

Start with 1 tablespoon of MCT oil per cup of coffee. Some people prefer more, but it’s best to start small, as too much MCT oil can cause digestive upset for some individuals. Gradually increase the amount as your body adjusts.

My bulletproof coffee is separating. What did I do wrong?

Separation usually means the ingredients didn’t fully emulsify. This can happen if the coffee wasn’t hot enough, if you didn’t blend for long enough, or if your blender’s speed wasn’t high enough. Try blending for an additional 30 seconds.

Is bulletproof coffee healthy?

Bulletproof coffee is high in fat and can be very satiating, which may help with appetite control for some. However, it’s also very calorie-dense and lacks many nutrients found in a balanced breakfast. Its health benefits are often debated and depend on individual dietary goals.

Can I make bulletproof coffee ahead of time?

It’s best to drink bulletproof coffee immediately after blending. The emulsification is temporary, and it will start to separate if left to sit. Reheating may also alter the texture and flavor.

What if my Ninja blender isn’t designed for hot liquids?

If your Ninja blender is not specifically rated for hot liquids, do not use it for bulletproof coffee. The heat can damage the blender’s components or cause the lid to fail, leading to a dangerous spill. In this case, use a separate immersion blender or a traditional blender that is safe for hot liquids.
