If you’re looking for a smoothie that’s thick, creamy, satisfying, and incredibly easy to make, this Green Peanut Butter Smoothie deserves a spot in your breakfast rotation.
It combines frozen banana, fresh spinach, creamy peanut butter, and almond milk into a beautifully smooth green drink. The frozen banana provides natural sweetness and a thick texture, while peanut butter makes every sip extra creamy and satisfying.
And the best part? You only need 4 main ingredients and a blender.
Green Peanut Butter Smoothie
Prep Time: 5 minutes
Total Time: 5 minutes
Servings: 1 large smoothie
Method: Blender
Ingredients
- 1 ripe banana, sliced and frozen
- 1 generous handful fresh spinach
- 2 tablespoons creamy peanut butter
- 1 cup (240 ml) unsweetened almond milk or oat milk
Optional Toppings
- Fresh banana slices
- Peanut butter drizzle
- Chia seeds
Step 1: Start With an Empty Blender
Start with a clean, empty blender.
Using a high-powered blender will give you the smoothest texture, especially when blending frozen banana and fresh spinach.
For easier blending, add the ingredients in the order below.
Step 2: Add the Frozen Banana 🍌
Cut one ripe banana into chunks and freeze it ahead of time.
Add the frozen banana pieces to the blender.
Using frozen instead of fresh banana is one of the easiest ways to make this smoothie naturally thick and creamy without adding lots of ice.
For an even sweeter smoothie, use a banana that was very ripe before freezing.
Step 3: Add Fresh Spinach 🥬
Add one generous handful of fresh spinach.
Don’t worry about the amount of greens—the banana and peanut butter help balance the spinach flavor.
Fresh baby spinach works especially well because it blends easily and has a mild flavor.
Step 4: Add the Peanut Butter 🥜
Spoon 2 tablespoons of creamy peanut butter into the blender.
Peanut butter gives this smoothie its rich, nutty flavor and makes the texture feel even creamier.
Both smooth natural peanut butter and conventional creamy peanut butter can work. Just keep in mind that the sweetness and consistency may vary between brands.
Step 5: Pour in the Almond Milk
Add 1 cup (240 ml) almond milk.
You can also substitute oat milk if you prefer.
For a thicker smoothie, start with slightly less milk and add more only if your blender needs it.
This is especially helpful if you’re trying to get that beautiful thick, spoonable smoothie texture rather than a thin drink.
Step 6: Blend Until Smooth
Secure the lid and blend on high until everything is completely combined.
You’ll see the ingredients transform from:
banana + spinach + peanut butter + milk
into a creamy green mixture.
Continue blending until there are no visible pieces of spinach remaining.
The finished smoothie should be:
Thick + silky + creamy + smooth + naturally green.
If it’s too thick for your blender, add another splash of almond milk and blend again.
If it’s too thin, add a few more pieces of frozen banana.
Step 7: Check the Texture
Before pouring, scoop up a little smoothie with a spoon.
A properly thick smoothie should coat the spoon and slowly fall back into the blender in a heavy, creamy ribbon.
It shouldn’t pour like juice.
This little texture check is especially useful if you want that thick café-style consistency.
Step 8: Pour Into a Glass 🥤
Pour the smoothie directly from the blender into a tall glass.
Because frozen banana creates such a creamy consistency, the smoothie should pour slowly and settle into a soft swirl on top.
For the best texture, serve it immediately.
Step 9: Add the Toppings
You can drink it as-is, but a few simple toppings make it even better.
Arrange several thin banana slices on top.
Drizzle a small amount of creamy peanut butter across the surface.
Finish with a light sprinkle of chia seeds for extra texture.
The combination of soft green smoothie + banana + golden peanut butter + tiny chia seeds also makes the finished drink look great in photos or recipe videos.
⭐ How to Make Your Smoothie Extra Thick
The biggest secret is frozen banana.
Avoid adding lots of ice because it can dilute both the flavor and creaminess.
Also, don’t automatically pour in extra milk. Start with the recipe amount—or slightly less if you prefer an especially thick smoothie—and only add more when necessary for blending.
For the creamiest result:
Use frozen banana → don’t overdo the liquid → blend thoroughly → serve immediately.
Easy Variations
🍫 Chocolate Peanut Butter Green Smoothie
Add 1 tablespoon unsweetened cocoa powder before blending for a chocolate-peanut-butter variation.
🫐 Berry Green Smoothie
Add about ½ cup frozen blueberries or strawberries. The flavor will be fruitier, although the final color may no longer be bright green.
🌱 Chia Green Smoothie
Add 1 tablespoon chia seeds directly to the blender. Let the smoothie sit for a few minutes after blending if you want the chia to thicken it further.
🥣 Extra-Thick Smoothie Bowl
Reduce the almond milk and blend until extremely thick. Pour into a bowl and top with banana, peanut butter, chia seeds, fruit, or granola.
