Put the cake pieces in a food processor and blend until you get a fine breadcrumb like consistency.
Add the spread and blend until everything is well incorporated. Stop and scrape the side as needed.
Put the mixture into the fridge to firm for at least 30 minutes.
Shape into small balls, try to keep them the same size, using a teaspoon for measure.
Place into a plate lined with parchment paper and place them back in the fridge to firm up.
You go let your imagination go wild, when it comes to decoration. I coved a third of them with desiccated coconut, the other third with cocoa nibs and the last one with melted dark chocolate that I added some cocoa nibs inside. Any crushed nuts would work nicely here.
Refrigerate for at least 2 hours and enjoy!
