Add the vanilla ice cream, milk, maple syrup, chopped walnuts, vanilla extract, and salt to a blender. Tip: For a thicker shake, use frozen milk cubes instead of fresh milk.

Blend on high speed until smooth and creamy, about 30-45 seconds. Tip: If the shake is too thick, add a splash more milk and blend again.

Pour into tall glasses and garnish with extra chopped walnuts or a drizzle of maple syrup if desired. Tip: Serve immediately for the best texture.
