Prep the banana: Slice half the banana for layering and keep the rest aside for blending.
Blend the pudding base: In a blender, combine cottage cheese, Greek yogurt, the remaining banana, protein powder, sweetener, vanilla, and a pinch of salt. Add almond milk as needed. Blend until completely silky and smooth.
Adjust sweetness & texture: Taste and adjust sweetness. If too thick, add milk 1 tablespoon at a time. If too thin, add 1–2 tablespoons more protein powder or Greek yogurt.
Assemble: Layer pudding with banana slices, crushed healthy cookies, chia seeds, or granola if desired.
Chill: Refrigerate 1–2 hours for the best thick, creamy texture.
Serve & store: Enjoy immediately or store in airtight jars for up to 4 days. Add banana slices right before eating.
