I think you would need to either
add more coconut butter or consider adding ground nuts or fruit or all of the above.
It's a little thicker though so you may
need more coconut butter (an extra 2 tbsps or so) to get the right dough texture.
You could gently melt the strawberry truffles back down (I would place them in a bowl and place that bowl in another bowl of warm water, making sure to not get the truffles wet) and then stir in
some more coconut butter to firm them up.
The same happened when I made coconut meal, which was supposed to be
more coconut butter, but I think my whimpy, old food processor couldn't keep up for the full 20 minutes required to make two batches.
Can't wait to get
some more coconut butter so I can try it.
