Toss the frozen banana, oats, peanut butter, and almond milk into your trusty blender. Give it a whirl until everything becomes silky smooth. Add some ice and any other extras you like, blend again, and witness the creamy magic unfold.
Pour the goodness into one big glass or two smaller ones. Feel free to sprinkle some chocolate chips on top if you're feeling a bit fancy.
VoilĂ ! You've just created a fantastic peanut butter banana smoothie that's perfect for starting your day on a tasty note.
