Cross-Contamination Warning for Gluten-Free Banana Oat Smoothie: When preparing this drinks and smoothies recipe, it is crucial to use gluten-free oats, as gluten-free oats are often processed in facilities that handle gluten-containing grains. Ensure all other ingredients, such as almond milk and almond butter, are also gluten-free to prevent accidental gluten exposure. In a shared kitchen, avoid porous materials — wooden spoons, wooden cutting boards, and scratched non-stick pans can harbor gluten proteins even after washing. Prefer glass, metal, or silicone tools.
Gluten-Free Notes for Gluten-Free Banana Oat Smoothie: Oats are the ingredient here that needs a gluten-free label, because ordinary oats are routinely cross-contaminated with wheat. Check almond milk and almond butter labels too if they are flavored.

Tips & Notes
- Refrigerate leftovers covered and finish them within a day. They thicken to a pudding within an hour, so stir in a splash of milk or eat it with a spoon.
- Overnight version: put the oats and almond milk in the blender jar, cover and refrigerate overnight. In the morning add the rest and blend; soaked oats blend silkier.
- Quick-cooking oats labeled gluten-free blend fastest; old-fashioned oats work just as well once powdered.
- Swap the almond butter for peanut butter, or add 1/4 cup plain Greek yogurt for a tangier, creamier glass.

Can I make a banana oat smoothie the night before?
Soak the oats in the almond milk overnight in the blender jar and blend everything in the morning. A fully blended smoothie made the night before turns thick and pudding-like.
