Ingredients You’ll Need
- 1 1/2 cups frozen blueberries
- 1 ripe banana
- 2 tablespoons natural peanut butter
- 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
- 3–5 ice cubes
Pro Tips
Using frozen blueberries is the easiest way to get a thick, creamy smoothie without watering it down.
They also help keep the smoothie cold and refreshing without needing too much ice.
Choose natural peanut butter with minimal added sugar for the best flavor and texture. Stir it well before measuring to ensure a smooth blend.
If you want an extra-creamy texture, use a frozen banana instead of a fresh one. This makes the smoothie thicker and more milkshake-like.
Start blending on low speed, then gradually increase to high. This helps the peanut butter blend evenly and prevents it from sticking to the sides of the blender.
Always taste the smoothie before serving. Depending on the sweetness of your blueberries and banana, you may want to adjust the honey or maple syrup slightly.
Tools You’ll Need
- High-speed blender
- Measuring cups
- Measuring spoons
- Spatula
- Glasses or jars for serving
Substitutions and Variations
This peanut butter blueberry smoothie is easy to customize. 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 peanut butter for almond butter or cashew butter if you prefer a different nut flavor. For a nut-free option, sunflower seed butter works beautifully.
If you’d like to add more protein, blend in a scoop of unflavored or vanilla protein powder. Chia seeds or ground flaxseed add fiber and nutrition without changing the flavor much.
A small handful of spinach can also be added for extra nutrients—the blueberry flavor masks it well.
Make Ahead Tips
This smoothie works very well for make-ahead prep. One easy option is to prepare freezer smoothie packs.
Combine frozen blueberries, sliced banana, and measured peanut butter (freeze in small scoops or parchment-lined dollops) in freezer-safe bags. When ready to blend, simply add the liquid ingredients.
You can also blend the smoothie completely and store it in an airtight container in the refrigerator for up to 24 hours.
The smoothie may thicken slightly as it sits, but a quick shake or stir usually restores smoothness.
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 3: Add liquids and flavorings
Pour in the milk and add the Greek yogurt, honey or maple syrup, and vanilla extract. These ingredients create a smooth, creamy texture.
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 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.

Leftovers and Storage

As it sits, the smoothie may thicken slightly due to the banana, yogurt, and peanut butter. Stirring or shaking before drinking helps restore the original texture.
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 creamy consistency.
Avoid leaving the smoothie at room temperature for extended periods, especially if it contains dairy, to maintain freshness and food safety.
