Combine ¼ cup rolled oats and ¼ cup water in a microwave-safe bowl. Microwave on high for 2 minutes. Set the cooked oats aside to cool until they are no longer very hot.

In a blender add ½ cup milk, ⅓ cup plain Greek yogurt, ½ teaspoon ground cinnamon, a pinch of turmeric, the cored and roughly chopped apple, ¼ teaspoon vanilla extract, 1 teaspoon pure maple syrup, a small squeeze of fresh lemon juice, and the chopped pitted date (if using).

Add the cooled cooked oats to the blender.

Add ice cubes to the blender to achieve your desired thickness.

Blend on high until the mixture is smooth and uniform, stopping to scrape down the sides if needed.

Pour into a glass or jar and finish with a light dusting of ground cinnamon on top.
