I bought from an online Filipino store a few items and they gave me a small jar of Ube Butter for free. The ube butter is similar to Biscoff spread because it is also made with cookies and butter. The cookies have ube flavoring, most likely unnatural and not real ube (purple yam from the Philippines). I didn't like it because it is too sweet for my taste and I was put off by the violent color. Yes, violent is not a typo.
Ube is not supposed to be this dark violet. Real ube yam is a lighter shade of purple and when cooked in milk and sugar should be light purple or very dark lilac. I also didn't like the artificial flavor of the store-bought ube butter so I made my own with homemade Ube Jam and butter plus a little powdered xylitol. Needless to say I prefer homemade Ube Butter because it is made with just Ube Jam and salted butter and the color is very very light lilac. I prefer salted butter because IMHO, salt enhances the flavor of sweets.
If you are using store-bought ube jam, make sure the color is not very dark purple because it will taste of fake ube flavoring that comes in a small bottle. If you don't mind the artificial flavor, then go ahead and use it.
