Ingredients You’ll Need
- 1 1/2 cups frozen mango chunks
- 1 ripe banana
- 1/2 cup rolled oats
- 1 cup milk (dairy or unsweetened almond milk)
- 1/2 cup plain Greek yogurt
- 1 tablespoon honey or maple syrup
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
- 3–5 ice cubes
Pro Tips
Using frozen mango is the easiest way to get a thick, creamy smoothie without watering it down. It also keeps the smoothie cold and refreshing without relying heavily on ice.
If you’re new to adding oats to smoothies, rolled oats work best. They blend smoothly and add body without making the smoothie feel gritty.
For extra smoothness, especially for kids, soak the oats in the milk for 10 minutes before blending. This softens them and creates a silkier texture.
Start blending on low speed, then gradually increase to high. This helps break down the oats evenly and prevents chunks from sticking to the bottom.
Taste the smoothie before serving and adjust sweetness as needed. Mango sweetness can vary, so a little extra honey or maple syrup may help balance the flavor.
Tools You’ll Need
- High-speed blender
- Measuring cups
- Measuring spoons
- Spatula
- Glasses or jars for serving
Substitutions and Variations
This mango banana oat smoothie is very flexible. If you don’t have Greek yogurt, regular plain yogurt works well, though the smoothie will be slightly thinner.
For a dairy-free version, use plant-based milk and coconut or almond milk yogurt.
You can swap mango for peaches or pineapple for a slightly different tropical flavor. If bananas aren’t your favorite, half an avocado can replace them for creaminess without added sweetness.
For added protein, blend in a scoop of unflavored or vanilla protein powder. Nut butters such as almond or peanut butter add richness and make the smoothie even more filling.
Chia seeds or ground flaxseed can be added for extra fiber and nutrition without significantly changing the flavor.
Make Ahead Tips
This smoothie is excellent for make-ahead prep. One easy option is to prepare freezer smoothie packs.
Combine frozen mango, rolled oats, and sliced banana in freezer-safe bags. When ready to blend, simply add the liquid ingredients and blend.
You can also blend the smoothie completely and store it in an airtight container in the refrigerator for up to 24 hours.
The oats will continue to absorb liquid, so the smoothie may thicken slightly. A quick shake or stir usually restores a smooth consistency.
For longer storage, freeze the blended smoothie in freezer-safe jars or silicone molds. Thaw overnight in the refrigerator and blend briefly before serving to bring back the creamy texture.
Step-by-Step Instructions
Step 1: Add the base ingredients
Add the frozen mango, rolled oats, and banana to the blender. These ingredients create the foundation of the smoothie and help achieve a thick, creamy texture.
Step 2: Add liquids and dairy
Pour in the milk and add the Greek yogurt. These ingredients soften the oats and balance the sweetness of the fruit.
Step 3: Add sweetener and flavorings
Add the honey or maple syrup, vanilla extract, and ground cinnamon. These ingredients enhance the natural flavors and add warmth.
Step 4: Add ice and blend
Add the ice cubes. Start blending on low speed, then gradually increase to high. Blend for 60–90 seconds, or until the smoothie is completely smooth.
Step 5: Adjust and serve
Check the consistency and taste. Adjust thickness or sweetness if needed, then pour into glasses and serve immediately.
Serving Suggestions
- Serve with whole-grain toast for a balanced breakfast
- Pair with scrambled eggs or yogurt for extra protein

Leftovers and Storage
Leftover smoothie can be stored in an airtight container in the refrigerator for up to 24 hours.
As it sits, the oats will continue to thicken the mixture, creating a denser texture. Stirring or shaking before drinking helps restore smoothness.
For freezing, pour the smoothie into freezer-safe jars or molds. Thaw overnight in the refrigerator or at room temperature for a few hours. Blending again briefly helps bring back the original creamy consistency.
Avoid leaving the smoothie at room temperature for extended periods, especially if it contains dairy, to maintain freshness and food safety.
