Start by mixing oats, ground flax, cocoa powder, and honey in a medium bowl. You gotta stir well so the cocoa distributes evenly, or you’ll find clumps later.
Adding milk and peanut butter. Stir it all up till smooth and creamy. This part is kinda important ‘cause peanut butter melts better when stirred well into the milk.
Fold in banana slices, peanuts, and chocolate chips if you’re using ‘em. Don’t overmix once you add fruits and chips or they might break down too much.
Scoop the mixture evenly into your jars or containers. This way you get ready meals that can chill overnight easy.
Put lids on your containers and pop into the fridge. The slow soak overnight really lets flavors get tender and friendly.
