Add the yogurt and any milk or water to the blender first before adding the frozen ingredients. Starting with the liquid at the bottom helps the blender run more smoothly and prevents ingredients from getting stuck around the blades. Greek yogurt creates a thicker, creamier smoothie, while almond milk or water gives it a lighter texture.

Add the blueberries and banana to the blender. Frozen blueberries work especially well because they create a cold, thick smoothie with a rich berry flavor and vibrant purple color. The banana naturally sweetens the smoothie and helps create a silky, creamy consistency without needing extra sugar.

Sprinkle the chia seeds and cinnamon evenly over the fruit. The chia seeds help thicken the smoothie slightly while adding fiber and texture, and the cinnamon gives the smoothie a warm, cozy flavor that balances the berries beautifully.

Add the peanut butter along with any optional ingredients you’d like to include, such as spinach, ginger, turmeric, flaxseed, protein powder, or ice cubes. Peanut butter adds richness and helps make the smoothie feel more satisfying and balanced, while spinach blends surprisingly well into the blueberry flavor without becoming overpowering.

Secure the blender lid tightly and blend everything on high speed for about 45–60 seconds, or until the smoothie becomes completely smooth and creamy. Pause and scrape down the sides if needed to help all the ingredients blend evenly. The final texture should be thick, creamy, and silky with no chunks remaining.

Check the consistency after blending. If the smoothie feels too thick, add a small splash of milk or cold water and blend again briefly until it reaches your preferred texture. If you prefer an even thicker smoothie, add a few extra frozen blueberries or ice cubes.

Taste the smoothie before serving and adjust the flavor if needed. Add a little extra cinnamon for warmth, more peanut butter for richness, or a drizzle of honey or maple syrup if you prefer a sweeter smoothie.

Pour the smoothie into chilled glasses or jars and serve immediately while cold and fresh. If desired, garnish with extra blueberries, chia seeds, cinnamon, or a drizzle of peanut butter for a cozy café-style presentation.
