Chunks of creamer float on surface my coffee?

Insufficient Mixing: If you haven't stirred your coffee enough, the creamer may not fully dissolve and form clumps at the surface. Use a spoon or a whisk to mix your coffee thoroughly until the creamer is evenly dispersed.

Cold Coffee: If your coffee is too cold, the creamer may not melt completely and might appear as chunks on the surface. Ensure your coffee is hot enough to dissolve the creamer.

Type of Creamer: Different types of creamers may have different compositions that affect how they mix with coffee. Some creamers, especially ones with higher fat content or certain ingredients, may be less soluble and prone to clumping.

Creamer Temperature: The creamer's temperature can also affect how it mixes with the coffee. If the creamer is too cold, it may solidify in contact with the hot coffee, forming lumps.

Lumpy Creamer: Some creamers may naturally have a slightly lumpy texture due to their ingredients or processing. Check the creamer's consistency before adding it to your coffee to ensure it's smooth.
