Prepare frozen ingredients: Let frozen banana and cauliflower thaw for 2-3 minutes for easier blending, but keep them mostly frozen for thick consistency.
Add liquid first: Pour almond milk into a high-speed blender to help with blending.
Add creamy ingredients: Add almond butter, honey, and vanilla extract to the blender.
Add dry ingredients: Add protein powder, cocoa powder, and a pinch of salt.
Add frozen ingredients: Add frozen banana chunks and cauliflower florets last.
Blend to perfection: Start blending on low speed, then gradually increase to high. Blend for 60-90 seconds until completely smooth and thick like soft-serve ice cream.
Check consistency: The mixture should be very thick - add more almond milk only if absolutely necessary, using as little liquid as possible.
Serve immediately: Pour into a chilled bowl using a spatula to get every bit.
Add toppings: Arrange toppings in sections or rows on top of the smoothie base for beautiful presentation. Serve immediately with a spoon.
