Trader Joe’s Speculoos Cookie Butter has to be the most popular cookie butter there is, and easily the brand that gets sold out very quickly. In some states, you can’t buy more than 2 or 3 cookie jars. Don’t go hoarding. It comes in two varieties: Creamy and Crunchy. Creamy is much more refined than Crunchy. But if you like nipping on sweets, crunchy is something that’s a clear winner for the sweet tooth.
