Adding raw oats to this shake produces a pleasantly chewy texture while providing fiber, which helps keep cholesterol levels in check.
Freeze pears in a single layer on a baking sheet overnight.
Combine pears, milk, buttermilk, oats, ice, maple syrup, almond butter, ginger, cinnamon, and a pinch of salt in a blender. Blend on low speed, then gradually increase speed to high. Blend until smooth, 1 to 2 minutes. Pour into chilled glasses, and garnish with ground cinnamon. Serve immediately.
Freezing the pears overnight reduces the amount of ice needed for blending the next day and results in a thick and creamy texture.
