In a high-speed blender, combine the chia seeds, your choice of milk, peanut butter, cocoa powder, maple syrup or honey, and vanilla extract. Blend until smooth.

Pour the blended mixture into a bowl or airtight container, and stir to ensure the chia seeds are evenly distributed.

Cover tightly and refrigerate for at least 4 hours or preferably overnight to allow the pudding to set.

Before serving, stir the pudding to achieve a smooth texture. If it's too thick, add a splash of milk.

Spoon into bowls and add toppings like fresh fruit, nuts, or granola before serving.
