Tips & Variations

Use chocolate or vanilla protein powder based on your flavor preference to customize sweetness and richness.
Swap walnuts for almonds or pecans for different textures and flavors.
For extra texture, sprinkle some shredded coconut or chia seeds on top before serving.
If you prefer a sweeter oatmeal, increase the maple syrup slightly or add a drizzle of honey.

Storage

Store any leftover overnight oats covered in the refrigerator for up to 3 days. Stir well before serving and add a little almond milk to loosen if needed. This recipe is best enjoyed cold but can be warmed gently if you prefer.
