Mix oats, coconut, peanut butter, flaxseed, chocolate chunks, maple syrup and vanilla, until combined, in a large bowl.
Scoop and press the mixture directly into the wells of your Souper Cubes 2-Tbsp trays. For this recipe you will need three Souper Cubes 2-Tbsp trays, which will give you 30 portions.
Place the trays with labeled lids in the freezer overnight to fully freeze.
Remove the trays from the freezer and allow the trays to stand on the counter for 5 minutes before removing the lid and pop out the frozen cubes. This will allow the cubes to pop out much easier for you.
Optional: Pop-out the cubes and transfer them to freezer-safe bags. Label and return back to the freezer.
Let stand overnight in the refrigerator overnight to thaw or let stand on the counter for an hour to thaw before eating.
