I don’t know if’s a direct replacement for Butter EZ, but I believe Cera Bellina can be used for the same effect. I have some that I haven’t had a chance to try. It’s pricey at $2-3 per ounce.
WSP sells Cera Bellina as Smooth & Creamy Lotion Bar Additive: “Crafter's Choice Smooth & Creamy Lotion Bar Additive is a beeswax derivative that has gained tremendous popularity in lotion bar and lip balm formulas. It prevents the grainy texture shea butter typically exhibits when cooled. When added at 5%, shea butter lotion bars are smooth and creamy.”

From Lotioncrafter: “Cera Bellina has the unique ability to give stability by forming non-granular gels of liquid oils. Besides the consistency regulating properties of beeswax, Cera Bellina has the remarkable capability of inhibiting crystallization in the oil phase and therefore enhancing stability by preventing the formation of granules. This attribute can eliminate the graininess or rice granule effect that can occur when using shea and other natural butters in anhydrous formulations such as lip balms and lotion bars.”
