Quick Answer: What Causes Fat Bloom?

Most commonly, this results when chocolate is exposed to warm temperatures, which causes the cocoa butter (aka fat) in the chocolate to soften.

When the fat melts, it separates from the other ingredients in the chocolate and rises to the surface, where it then re-solidifies and creates a grayish “bloom”.

How do you stop fat blooms?


Store your finished chocolate products at a constant temperature between 18°C and 20°C. Fat-based fillings (e.g. pralines or nut-based fillings) will make fat bloom appear faster. You can prevent this by adding 5% to 6% cocoa butter to your filling and then pre-crystallising (or tempering) it.

How do you fix a fat bloom in chocolate?
