This sweet, creamy plant-based smoothie is light, refreshing, and ready in about five minutes. With just four simple ingredients, it’s a quick breakfast option or a satisfying light dessert.
I often make this smoothie for a fast breakfast, but it’s sweet and satisfying enough to enjoy as a light dessert. The deep purple color comes from blackberries and the natural sweetness comes only from the fruit and creamy oat milk.
This berry banana smoothie uses frozen fruit for a frosty, smooth texture and unsweetened oat milk for a gentle, neutral base. For a hint of extra flavor, use vanilla oat milk.
If you want more berry ideas, try blueberry popsicles or a strawberry acai lemonade next.

Oat Milk: Unsweetened oat milk keeps the smoothie light; swap in vanilla oat milk for a slightly sweeter, more dessert-like flavor.
See the recipe card below for exact ingredient amounts.
Substitutions & Variations
Liquid base: Swap oat milk for almond milk, coconut milk, or a mild juice if preferred.
No banana: If you skip the banana, double the berries or add ½ cup of vanilla plant-based yogurt for creaminess and sweetness.
Different berries: Use any mix of berries you like—blackberries, strawberries, blueberries, or raspberries work well. Aim for about 1 ½ cups total.
Step by Step Instructions
Making this vegan blackberry strawberry banana smoothie is simple:
Step 1: If you don’t have frozen fruit, freeze it ahead of time. Alternatively, add one cup of ice with fresh fruit. Place the fruit and oat milk into a blender and secure the lid.
Step 2: Blend for about 30 seconds or until smooth and creamy. Adjust texture by adding more oat milk in ½ cup increments to thin, or more frozen banana or ice to thicken.
Expert Tips
- Always use frozen fruit when possible to avoid adding ice and to keep the smoothie creamy and undiluted.
- Freeze peeled bananas in portions. Peel, break in half, and freeze bananas so you always have them ready for smoothies.
- Freeze at peak ripeness. Freeze your fruit when it’s perfectly ripe for the best flavor in every batch.
Frequently Asked Questions
Oat milk is a favorite because it’s lightly sweet and adds a creamy texture, but plant milks like almond or coconut also work well.
Most fruit combinations work. Stick to like flavors if you prefer a safe choice—mix berries together or group tropical fruits for consistent flavor.
