Critical Steps — Do Not Skip
- Coffee must be hot enough to melt the butter completely.

Chef Tips from the Video
- Use freshly ground, high‑quality beans for the best aroma.
- Grass‑fed butter adds a richer, slightly nutty flavor.
- For extra flavor, add a pinch of cinnamon or vanilla extract.
Troubleshooting
The coffee separates and the butter floats on top.
Make sure the coffee is hot enough (≥90°C) and blend for an additional 15‑20 seconds.
The froth is thin and disappears quickly.
Use a high‑speed blender or hand frother and blend longer; consider adding a splash of MCT oil for extra emulsification.
Storage

Freezer: Not recommended; butter may separate.
Room temperature: Best consumed immediately; will separate after 30 minutes.
Make-Ahead Tips
- Pre‑soften butter and keep it at room temperature.
- Brew coffee in a thermos to keep it hot while you prepare the butter.
