Add almond milk, chocolate protein powder, hazelnut butter, cocoa powder, instant coffee granules, ice cubes, maple syrup (if using), and vanilla extract to a blender. Tip: For a thicker shake, use frozen almond milk cubes instead of regular ice.

Blend on high speed until smooth and creamy, about 1-2 minutes. Tip: If the shake is too thick, add a splash more almond milk.

Pour into tall glasses, garnish with a drizzle of hazelnut butter or a sprinkle of cocoa powder if desired, and serve immediately.
