Load the blender. Add frozen mixed berries, banana, yogurt, and 3/4 cup of your chosen liquid. If using add-ins like chia or flax, add them now.
Blend on low to start. Begin at a low speed to help the blades catch the frozen fruit, then gradually increase to high.
Adjust texture. If it’s too thick, splash in more liquid, 1–2 tablespoons at a time. If it’s too thin, add a few more frozen berries or a couple of ice cubes.
Taste and sweeten. Blend in honey, maple syrup, or a date if needed.
Add vanilla extract if you like a bakery-style aroma.
Blend until silky. Keep blending for 20–30 seconds after it looks smooth for an ultra-creamy finish with no berry bits.
Serve immediately. Pour into a chilled glass or travel tumbler. Top with a few extra berries or a sprinkle of chia for texture.
