This Bulletproof Coffee Keto Milkshake transforms your ordinary morning coffee into a creamy, satisfying treat that keeps hunger at bay for hours. As someone who struggled with mid-morning energy crashes, this milkshake became my secret weapon for sustained focus and satisfaction.
I discovered this recipe during my keto journey three years ago, and it's become my non-negotiable morning ritual. Even my non-keto friends request it when they visit for brunch!
Ingredients
- Brewed coffee: cooled to room temperature gives you that essential caffeine boost while providing a rich base
- Coconut cream: creates that luxurious milkshake texture without dairy – look for full-fat versions for best results
- Ice cubes: help achieve the perfect frosty consistency – use filtered water ice for the cleanest taste
- MCT oil: provides quick energy for your brain and supports ketosis – choose a quality brand with C8 and C10 MCTs
- Vanilla extract: adds warmth and depth to the flavor profile – opt for pure extract rather than imitation
- Stevia: offers sweetness without the carbs or calories – liquid stevia provides the most consistent results
Step-by-Step Instructions
- Brew Your Coffee:
- Start with freshly ground beans and brew a strong cup of coffee. Allow it to cool completely to room temperature to prevent melting the ice too quickly. For best results, brew coffee the night before and refrigerate.
- Gather Your Ingredients:
- Measure all ingredients precisely for balanced flavor. The coconut cream should be at room temperature to blend smoothly with the other ingredients. If it's separated in the can, whisk it first.
- Blend To Perfection:
- Add all ingredients to your high-speed blender in the order listed. Start blending at low speed for 10 seconds, then increase to high for another 20-30 seconds until the mixture reaches a smooth, creamy consistency with tiny ice particles remaining.
- Serve Immediately:
- Pour your milkshake into a tall glass right away. The texture is best when freshly blended, as it will begin to separate if left sitting too long.

The MCT oil is truly the magic ingredient here. When I skip it, I notice a significant difference in my mental clarity and how long I stay satisfied. My favorite morning ritual is enjoying this on my porch while planning my day—somehow ideas flow better with this creamy elixir in hand.
Frothy Perfection Technique
For those who crave that coffeehouse-style frothy top, reserve a small amount of coconut cream. After pouring your milkshake, whip the reserved cream with a tiny dash of vanilla and dollop it on top. This extra step elevates the experience from a simple keto breakfast to something that feels truly indulgent without adding significant carbs.

Flavor Variations
The basic recipe is incredibly versatile. Add a tablespoon of unsweetened cocoa powder for a mocha version. Cinnamon and a dash of nutmeg create a spiced variation perfect for fall mornings. For a more dessert-like treat, try adding a tablespoon of sugar-free chocolate chips or a teaspoon of almond butter. My household favorite is adding a few drops of peppermint extract during the holiday season.
Nutritional Benefits
This keto milkshake does more than satisfy cravings. The combination of caffeine and MCT oil provides clean energy while promoting ketone production. The healthy fats from coconut cream support hormone balance and provide sustained energy without insulin spikes. When I switched from sugary coffee drinks to this recipe, I noticed improved focus throughout my mornings and more stable energy levels. Many of my clients report similar benefits, plus reduced cravings throughout the day.
Frequently Asked Questions
- → Can I use hot coffee instead of cooled coffee?
No, hot coffee should be avoided as it will melt the ice too quickly and result in a watery consistency. Always allow your coffee to cool to room temperature before blending for the perfect milkshake texture.
- → What can I substitute for MCT oil?
Coconut oil is the best substitute for MCT oil as mentioned in the ingredients. You could also use grass-fed butter, though this will alter the flavor profile slightly while maintaining the high-fat keto principles.
- → Is this milkshake truly keto-friendly?
Yes, this milkshake is keto-friendly as it contains high fat from coconut cream and MCT oil, uses stevia as a zero-carb sweetener, and contains no added sugars or high-carb ingredients.
- → What toppings work well with this drink?
Keto-friendly toppings include unsweetened whipped cream, a sprinkle of cinnamon, cacao nibs, or a small amount of grated dark chocolate (85% or higher). Avoid sugary toppings to maintain the low-carb profile.
- → How many carbs are in this milkshake?
This milkshake is very low in carbohydrates, with most of the minimal carbs coming from the coconut cream. The exact count depends on your specific brands, but it typically contains less than 5g net carbs per serving.
- → Can I make this ahead of time?
This milkshake is best enjoyed immediately after blending. If you need to prepare in advance, you can mix all ingredients except ice and store in the refrigerator, then blend with ice just before serving.
