Step 1: Gather your ingredients. Make sure you have everything ready for a smooth blending process.
Step 2: Peel the ripe banana and break it into smaller pieces for easier blending.
Step 3: In your blender, combine the banana pieces, rolled oats, almond or soy milk, and water. Blend on high speed until smooth and creamy, about 30 seconds to 1 minute.
Step 4: Add the creamy peanut butter, ground cinnamon, and ground flaxseed. Blend again until well combined and smooth.
Step 5: Taste your smoothie. If you prefer it sweeter, add a drizzle of honey or maple syrup.
Step 6: Pour your Banana Oatmeal Smoothie into a glass and enjoy immediately. Optionally, sprinkle with cinnamon or top with sliced banana.
Notes
For an ultra-smooth texture, soak the oats in water for 10-15 minutes before blending. You can also add protein powder for an extra boost.
