As mentioned above, your almond butter may not roll because you didn't add enough sugar. However, if you're using an almond butter that contains extra oils you may need to add more sugar to get it to roll also. All brands of almond butter produce a slightly different result, and if you're using one that already has added sugars it may roll on its own without adding any more. I like the Good & Gather almond butter from Target that requires stirring.
