Peanut Butter Banana Date Smoothie (High Protein Breakfast Blend)

Every time I blend a new smoothie, I think this might be my favorite one yet. But this peanut butter banana date smoothie is one I keep coming back to. It’s creamy, naturally sweet, and blended with banana and Medjool dates, no added sugar needed.

It has all the hearty, comforting flavors of a homemade date muffin, only it’s a smoothie you can make in minutes.

With over 30 grams of protein from real, whole foods (no protein powders here), it’s the kind of breakfast that keeps you full and energized all morning long.

If you love dates or just have a few extra Medjool dates on hand, you’ve got to give this one a try. Every sip is a perfectly balanced mix of peanut butter, flax, cinnamon, banana, and those sweet little bits of date throughout.

Why You’ll Love This Peanut Butter Banana Date Smoothie

• Freezer-friendly with make-ahead packs for easy mornings.
• High in protein — 33 grams without using protein powder.
• Naturally sweetened with Medjool dates and banana, no added sugar needed.
• Quick breakfast that blends up in minutes.

Ingredients Needed

• Medjool dates (pitted)
• Frozen banana chunks
• Greek yogurt
• Milk (I like Fairlife for the extra protein)
• Vanilla extract
• Cinnamon
• Salt
• Powdered peanut butter (like PB2)
• Flax meal

Ingredient Notes

Medjool dates: Naturally sweet and caramel-like, they’re perfect for adding rich flavor without refined sugar. Cut them into smaller pieces for easier blending if your blender isn’t high-powered.

If you get ones with pits, make sure to remove before blending.

Frozen banana: Freezing overripe bananas is one of my favorite smoothie hacks. It adds creaminess and that signature smoothie texture.

Greek yogurt: My protein powerhouse! It gives the smoothie body and 18 grams of protein all on its own.

Powdered peanut butter: Big peanut butter flavor without the oil. Adds 6 grams of protein and keeps the smoothie light and balanced.

Flax meal: Boosts both protein (about 3 grams) and fiber while giving the smoothie a heartier texture.

Milk: I like Fairlife since it has extra protein per serving, but any milk will work fine here.

Cinnamon, vanilla & salt: These three bring cozy warmth and balance to every sip. I wouldn’t skip any of them.

Why I Use Powdered Peanut Butter: Powdered peanut butter gives all that nutty flavor without added oils. It’s mainly roasted peanuts with just a touch of sugar, and it blends perfectly into smoothies without making them heavy.

How to Make a Peanut Butter Banana Date Smoothie

Detailed recipe and instructions are in recipe card at bottom of post.

1. Prep the dates: If your dates aren’t already pitted, slice lengthwise and remove the pits. Cut each date into a few smaller pieces.
2. Add ingredients to blender: Start with milk to use the measurement markings on the blender cup, one less dish to wash! Then add vanilla, powdered peanut butter, flax meal, cinnamon, salt banana chunks, dates, and Greek yogurt.
3. Blend: If your blender has a smoothie button, use it. Otherwise, blend on low for 15 seconds, then high for about 60 seconds.
4. Adjust texture: For a thinner smoothie, simply use a bit more milk and slightly less yogurt.
5. Enjoy immediately: Pour into a tall glass and enjoy your high-protein breakfast blend.

Recipe Notes

• This smoothie makes about 16 ounces, or two smaller 8-ounce servings.
• If you have a high-powered blender like a Vitamix, you can skip cutting the dates into pieces.
• For easier cleanup, rinse the blender cup and blade right away. I hate trying to clean bits of dried on smoothie later!

Why I Love Adding Medjool Dates to Smoothies

Medjool dates are one of my favorite natural sweeteners. They bring a warm, caramel-like depth that makes smoothies taste indulgent without any added sugar.

But beyond flavor, they’re full of fiber and minerals like potassium and magnesium, both of which are great for morning energy.

I especially love how the dates blend into tiny flecks throughout the smoothie, giving it a little texture and natural sweetness in every sip.

Protein in This Smoothie

One thing that makes this smoothie special is the protein content: a full 33 grams packed into one glass. Here’s where it all comes from:

• Greek yogurt — 18g
• Fairlife milk — 6.5g (other dairy milks average 4g)
• Powdered peanut butter — 6g
• Flax meal — 3g
• Banana + dates — about 2g combined

That’s a seriously satisfying amount of protein from whole ingredients, all without any expensive protein powders.

I’ve never been a fan of protein powders since they often include soy or artificial sweeteners, and this recipe proves you don’t need them.

How to Make a Banana Date Smoothie Freezer Pack

I love having a few of these ready to go for busy mornings.

1. In a small snack baggie, combine powdered peanut butter, flax meal, cinnamon, and salt.
2. In a freezer-safe sandwich bag, add the dry ingredient bag plus a ripe banana cut into 1-inch chunks.
3. When you’re ready to make the smoothie, just add milk, vanilla, yogurt, and pitted dates to the blender along with your freezer pack.

No need to freeze dates. They’d be too hard to blend. The frozen banana gives you all the cold, creamy texture you need.
