Try a Walnut Smoothie to Start Your Day
I love starting my day with one of my easy, feel-good smoothie recipes. Starting the day with a green smoothie – like this pear spinach smoothie (another favorite!) – just sets the tone for the rest of the day.
This particular version is a great way to add walnuts to smoothies, and tastes like a banana walnut muffin (plus the added goodness of greens). I love the unexpected addition of walnuts, oats, and cinnamon in this, plus the giant handfuls of baby spinach. And there’s no easier way to go than just throwing them into a blender and sipping on a delicious, green smoothie.
All you need to do for this quick & delicious breakfast recipe is add all your ingredients to a blender and let it work it’s magic.This banana walnut smoothie recipe serves two, which is perfect if you plan on splitting it with someone. If it’s just for you, though, simply halve the ingredients listed, or save the second serving in a tightly sealed container such as a mason jar for a snack later in the day or for breakfast the next day. The oats will thicken the leftovers a bit, so feel free to thin it out with extra milk if need be.
We’re Skipping the Yogurt! This banana smoothie without yogurt relies on almond milk to create the perfect creamy texture without any yogurt. And it gets a boost of protein from the protein powder & walnuts too!

Ingredients & Substitution Suggestions
Frozen banana: You can also use fresh banana in place of frozen banana in this recipe. The banana adds some natural sweetness to the smoothie. If using fresh banana in place of frozen, be sure to add ice to the blender for better texture.
Walnuts: I like adding whole roasted walnuts to this recipe but you can also swap in almond butter for the walnuts.
Baby spinach: I like to use tender, non-bitter greens for smoothies. But you can use any greens you like that blend easily and work well with these other ingredients. Some baby kale would work well in addition to (or in place of) spinach here too.
Vanilla protein powder: You can use any protein powder you like the taste of. To keep this recipe vegan friendly, be sure to use a plant-based. To keep this recipe paleo friendly, be sure to use a grain-free and dairy-free protein powder.
Milk: Any milk will work! For a nut-free option try hemp milk or oat milk. If you like a thinner consistency in your smoothies, add more milk.
Rolled oats: Adding some whole rolled oats helps thicken the smoothie, and also helps give this smoothie it’s banana walnut muffin flavor. Be sure to used gluten-free oats to keep this recipe gluten-free. And omit the oats entirely for a paleo-friendly version.
Cinnamon: Since it’s a classic baking spice, cinnamon also helps give this smoothie it’s banana bread muffin flavor. If you don’t like or don’t have cinnamon, you can omit it.
