Add the banana, Greek yogurt, and peanut butter into a blender or food processor. Break the banana into a few pieces before adding so it blends more easily. Start blending on a low speed to combine everything, then increase speed until the mixture becomes thick and creamy with no visible chunks.

Add the protein powder and cocoa powder directly into the blender. Blend again, starting slowly so the powders don’t fly up, then increase speed until everything is fully incorporated and the mixture turns into a rich, chocolatey base.

Continue blending for another 20–30 seconds until the pudding becomes completely smooth and silky. Pause if needed to scrape down the sides with a spatula so no dry powder or thick mixture is left behind.

Check the consistency of the pudding. If it feels too thick, add a small amount of milk (1–2 tablespoons at a time) and blend again until you reach your desired creamy texture. If it becomes too thin, you can balance it by adding a spoon of yogurt or a bit more protein powder.

For a thicker, more dessert-like texture, transfer the pudding into a bowl or jar and place it in the refrigerator for about 10–15 minutes. This helps it set slightly and enhances the flavor.

Once ready, give it a quick stir if needed and serve immediately. You can enjoy it as is or add toppings like sliced banana, chocolate chips, or chopped nuts for extra texture and flavor.
