This Keto Bulletproof Coffee is a frothy, warm drink made by blending freshly brewed coffee with butter and oil. The process creates a smooth, creamy texture and a thick foam on top, similar to a traditional latte, but without the use of milk or sugar.

About This Recipe

To get a consistent foam, the coffee must be mixed in a blender rather than stirred by hand. High-speed blending mixes the butter and oil with the hot coffee, which results in a velvety texture that stays integrated as you drink it. It is best to use a tall blender jar to ensure the liquid has enough room to froth up properly without splashing.

The flavor is rich and savory from the grass-fed butter, while the MCT or coconut oil adds a neutral finish. Because the fats are fully blended into the coffee, the drink has a heavy, rounded mouthfeel that is different from standard coffee with cream. This version uses only a few basic ingredients to create a drink that is thick and uniform in consistency.

If you prefer a different aroma, you can stir in a small amount of ground cinnamon or unsweetened cocoa powder before blending. It is important to use unsalted butter to maintain a balanced, clean taste. Once blended, the coffee should be served immediately while the foam is still light and airy.
