🥘Ingredients
- Banana: Use ripe bananas for natural sweetness and extra creaminess in your oats.
- Rolled oats: Opt for old-fashioned rolled oats for the best texture, quick oats can get mushy.
- Chia seeds: Boost fiber and omega-3s while thickening the oats. Make sure to stir well to avoid clumps.
- Protein powder: Adds extra staying power. Choose a vanilla or unflavored plant-based powder for the best taste.
- Plant-based milk: I used unsweetened almond milk for a light and creamy base, but you can substitute it with any dairy-free milk like cashew, coconut, or oat milk.
As always, you can find the full recipe with a list of ingredients with measurements in a printable recipe card at the end of this post.
