Place the frozen banana chunks into the blender, setting the stage for a thick, creamy base.
Add the peanut butter and strawberry jam on top of the banana. These ingredients will melt slightly during blending, creating a rich, sweet swirl.
Pour in the almond milk and Greek yogurt, which will help the mixture blend smoothly and add tang and creaminess.
Blend everything on high for about 30-45 seconds, stopping occasionally to scrape down the sides with a spatula. You want the mixture to be thick, smooth, and scoopable, with no visible chunks.
Check the consistency: it should hold a shape when scooped. If it’s too thick, add a splash more milk and blend briefly; if too thin, add a few more banana chunks and blend again.
Pour the smoothie mixture into a serving bowl, smoothing the top with a spatula for a clean presentation.
Finish by adding your favorite toppings—granola, chopped nuts, fresh berries, a drizzle of honey, or a sprinkle of sea salt—creating a colorful and textured final look.
Serve immediately and enjoy this nostalgic, creamy treat that’s both satisfying and full of flavor.
