If you love pumpkin pie (or not), try our delicious, creamy, and easy pumpkin pie smoothie with oats. We also love the color as it confers a fall-like and Halloween-like vibe. This pumpkin pie smoothie can be made vegan by using oat or almond milk. The cooked oats give it added nutritional benefits, including proteins and fibers. For added sweetness, use dates instead of maple syrup. Medjool dates are the best tasting dates and have a caramel-like flavor. However, you can substitute Medjool dates with your favorite type.
