- Vanilla extract: Brings out the sweetness of the other ingredients while enhancing the cookie-like flavor.

Instructions
Prep Tips
First, make the toasted oat topping so it can cool.
- Heat a skillet over medium heat.
- Melt the butter and add the oats, toasting while stirring for 4-5 minutes.
- Add the maple syrup, cinnamon, nutmeg, and salt. Heat through, stirring, for about a minute.
- Transfer to a bowl or plate and allow to cool to room temperature.
- Add the oats and date to the blender and blend for about 60 seconds to blitz the oats and chop the date.
- Add the rest of the ingredients and blend for about 60 seconds or until smooth and fully blended. Pause to scrape the sides down as needed. Add extra liquid only a tablespoon at a time if needed to help with blending.
Pour the smoothie mixture into a bowl and top with a tablespoon of the cooled oats. Add a chopped date and swirl of melted peanut butter if you want to garnish it more, or just serve.
