Slightly thaw the frozen acai packet under warm water for 5 seconds and break into smaller pieces.
Combine the acai chunks, protein powder, Greek yogurt, frozen blueberries, frozen banana, and almond milk in a high-speed blender.
Pulse the blender to break down solids, then blend on high while using a tamper to continuously press the frozen ingredients into the blades.
Process until the mixture is smooth with a thick, sorbet-like consistency, ensuring no large ice crystals remain.
Transfer the blended base into a chilled serving bowl immediately.
Garnish with chia seeds, almond butter, and granola.
