20 Peanut Butter Protein Smoothies Under 350 Calories

20 Peanut Butter Protein Smoothies Under 350 Calories

Peanut butter is basically nature’s apology for making healthy eating so boring.

You want something that actually tastes good, keeps you full until lunch, and doesn’t require a nutrition degree to assemble. You also want it under 350 calories — because you’re not trying to drink your entire day’s worth of food through a straw. This list gives you 20 peanut butter protein smoothies that hit all three marks, organized so you can find exactly what your body needs right now.

The “I Just Woke Up and I’m Not a Morning Person” Smoothies

These are built for speed, minimal thinking, and maximum protein payoff before your brain fully boots up.

1. Classic PB Banana Protein Shake

Blend 1 scoop vanilla protein powder, 1 tablespoon natural peanut butter, half a frozen banana, 1 cup unsweetened almond milk, and a handful of ice. That’s it. 330 calories, 28g protein. This is the smoothie I’ve made probably 400 times. It tastes like dessert, takes 90 seconds, and genuinely keeps me full for three hours. Don’t overthink it.

2. PB & Coffee Wake-Up Blend

Add 1 tablespoon peanut butter, 1 scoop chocolate protein powder, half a cup of cold brew concentrate, half a cup of unsweetened oat milk, and 5 ice cubes to your blender. Blend until smooth. 285 calories, 25g protein. Your caffeine AND your protein, unified. IMO this is the most underrated smoothie on this entire list.

3. Peanut Butter Greek Yogurt Smoothie

Combine ¾ cup plain non-fat Greek yogurt, 1 tablespoon peanut butter, half a frozen banana, ½ cup almond milk, and a dash of cinnamon. Blend hard. 290 calories, 24g protein. The Greek yogurt doubles the protein without adding a single scoop of powder — which matters if you’re tired of the chalky aftertaste that comes with some protein supplements.

4. PB Oat Breakfast Smoothie

Blend 2 tablespoons rolled oats (raw, they blend fine), 1 tablespoon peanut butter, 1 scoop vanilla protein powder, 1 cup unsweetened almond milk, and ice. 320 calories, 27g protein. The oats add slow-digesting carbs that make this feel more like a meal than a drink. Pro Tip: soak the oats in the almond milk for 5 minutes first — your blender will thank you and the texture will be noticeably smoother.

5. Frozen PB & Strawberry Shake

Toss 1 tablespoon peanut butter, 1 cup frozen strawberries, 1 scoop vanilla protein powder, and ¾ cup unsweetened almond milk into the blender. Blend until thick. 270 calories, 25g protein. Peanut butter and strawberry is criminally underrated. Everyone defaults to banana like it’s the law.

Quick reality check: if you’ve been skipping breakfast because “nothing sounds good,” that’s your sign. These first five take less time than scrolling Instagram for a good recipe. Speaking of quick options, these 15-minute high-protein smoothies are worth bookmarking too.

The “I Need This to Actually Keep Me Full” Smoothies

Higher protein, more staying power. These are your between-meals lifesavers.

6. Double Protein PB Shake

Blend 1 scoop chocolate protein powder, 2 tablespoons powdered peanut butter (PB2), 1 cup unsweetened almond milk, ½ cup non-fat Greek yogurt, and ice. 310 calories, 35g protein. Powdered peanut butter is the secret weapon here — you get full peanut butter flavor at a fraction of the fat calories, leaving room to double up on protein sources. This is the one I reach for on heavy training days.

7. PB & Chia Satiety Smoothie

Combine 1 tablespoon peanut butter, 1 tablespoon chia seeds, 1 scoop vanilla protein powder, 1 cup unsweetened almond milk, half a frozen banana, and ice. Blend, then let it sit 2 minutes — the chia thickens it up. 335 calories, 26g protein. Chia seeds absorb 10 times their weight in liquid, which means this smoothie literally expands in your stomach. Counterintuitive? Yes. Effective? Absolutely.

8. PB Hemp Protein Powerhouse

Blend 2 tablespoons hemp seeds, 1 tablespoon natural peanut butter, 1 scoop vanilla protein powder, 1 cup unsweetened oat milk, and a handful of frozen spinach. 320 calories, 30g protein. You will not taste the spinach. I promise. I used to be deeply skeptical of this claim, and I was completely wrong. The peanut butter masks everything.

9. Peanut Butter Cottage Cheese Smoothie

Okay, stay with me. Blend ½ cup low-fat cottage cheese, 1 tablespoon peanut butter, ½ cup unsweetened almond milk, ½ cup frozen mango, and ice. 280 calories, 28g protein. Cottage cheese in a smoothie sounds like a bad idea until you try it — it blends completely smooth and adds a creamy texture that protein powder can’t replicate. The mango cuts through any savory edge.

10. PB Collagen Booster

Combine 1 tablespoon peanut butter, 1 scoop unflavored collagen peptides, 1 scoop vanilla protein powder, 1 cup unsweetened almond milk, and ½ frozen banana. 300 calories, 32g protein. Collagen dissolves completely invisible — no flavor, no texture — but stacks seamlessly with your other protein sources. Why This Works: collagen contains glycine and proline, amino acids that most protein powders are low in, making this combo more complete than either alone.

The “I’m Watching My Macros Seriously” Smoothies

Under 300 calories, high protein, no compromise on taste. These are the ones nutritionists would actually approve of.

11. Lean PB Vanilla Shake

Blend 2 tablespoons PB2 powdered peanut butter, 1 scoop vanilla whey isolate, 1 cup unsweetened almond milk, and 6 ice cubes. That’s the whole recipe. 220 calories, 30g protein. Whey isolate is lower in carbs and fat than concentrate, which is why this hits such a clean macro split. If you’re building toward a high-protein weight loss plan, this becomes your non-negotiable breakfast.

12. PB Blueberry Antioxidant Shake

Combine 1 tablespoon natural peanut butter, ¾ cup frozen blueberries, 1 scoop vanilla protein powder, ¾ cup unsweetened almond milk, and ice. Blend until purple and gorgeous. 265 calories, 24g protein. Blueberries are one of the lowest-calorie fruits you can blend — you get volume, flavor, and a serious antioxidant hit without the sugar spike that comes with mango or pineapple.

13. PB & Pumpkin Spice Shake (Year-Round, No Apologies)

Blend 3 tablespoons canned pumpkin puree, 1 tablespoon peanut butter, 1 scoop vanilla protein powder, ¾ cup unsweetened almond milk, ½ teaspoon pumpkin spice, and ice. 255 calories, 24g protein. Yes, this works in July. Pumpkin puree adds fiber and volume for almost zero calories. Tbh, I stopped waiting for fall to make this about two years ago and never looked back.

14. Dark Chocolate PB Shake

Combine 1 tablespoon natural peanut butter, 1 tablespoon unsweetened cocoa powder, 1 scoop chocolate protein powder, 1 cup unsweetened almond milk, and ice. Blend until dark and thick. 270 calories, 27g protein. Unsweetened cocoa adds deep chocolate flavor for about 12 calories. It also contains theobromine, a natural stimulant that gives you a mild energy lift — without the coffee jitters.

15. PB Raspberry Tart Shake

Blend 1 tablespoon peanut butter, ¾ cup frozen raspberries, 1 scoop vanilla protein powder, ¾ cup unsweetened almond milk, and 4 ice cubes. 250 calories, 24g protein. The tartness of raspberries cuts through the richness of peanut butter in a way that’s genuinely surprising. Pro Tip: raspberries are high in fiber relative to their size — this smoothie has roughly 8g of fiber, which is more than most people get from an entire meal. Pair this with ideas from this 12-smoothie metabolism-boosting collection for a full week’s rotation.

You’ve made it halfway through this list and your blender is probably calling your name right now. 🥜 That’s a good sign. Keep going — the last five are where things get genuinely creative.

The “I’m Bored of Basic Smoothies” Smoothies

These push the flavor combinations somewhere unexpected. All under 350 calories, all legitimately delicious.

16. PB & Matcha Green Smoothie

Blend 1 tablespoon natural peanut butter, 1 teaspoon matcha powder, 1 scoop vanilla protein powder, 1 cup unsweetened oat milk, half a frozen banana, and ice. 315 calories, 25g protein. Matcha and peanut butter sounds like a collision, but the earthiness of the matcha and the nuttiness of the peanut butter land in the same flavor family. This is the one friends always ask about when they see you drinking it.

17. PB Tropical Protein Shake

Combine 1 tablespoon PB2, ½ cup frozen mango, ¼ cup frozen pineapple, 1 scoop vanilla protein powder, and 1 cup unsweetened coconut water. Blend hard. 290 calories, 24g protein. Using powdered peanut butter here keeps the calories low enough to fit the tropical fruits in. The coconut water adds electrolytes naturally — FYI, this one doubles as a solid post-workout option on hot days.

18. PB Ginger Spice Recovery Shake

Blend 1 tablespoon natural peanut butter, ½ teaspoon fresh grated ginger, ½ cup frozen mango, 1 scoop vanilla protein powder, and 1 cup unsweetened almond milk. 295 calories, 24g protein. Ginger is an anti-inflammatory ingredient that research links to reduced muscle soreness — which makes this perfect post-training. If you’re serious about recovery nutrition, this pairs well with a broader muscle recovery meal plan.

19. PB Cinnamon Roll Shake

Combine 1 tablespoon peanut butter, 1 scoop vanilla protein powder, ½ teaspoon cinnamon, ¼ teaspoon vanilla extract, 1 cup unsweetened almond milk, and 3 ice cubes. Blend. 265 calories, 25g protein. This tastes so close to dessert that it almost feels like cheating. It doesn’t have a single gram of added sugar, and yet somehow it hits that sweet-spiced note that makes you feel like you’re getting away with something.

20. PB Black Bean Chocolate Smoothie

One tablespoon natural peanut butter, ¼ cup canned black beans (rinsed, drained), 1 tablespoon unsweetened cocoa powder, 1 scoop chocolate protein powder, ¾ cup unsweetened almond milk, and ice. Blend until completely smooth — this takes 45 seconds minimum. 330 calories, 32g protein. 😲 Black beans in a smoothie. I know. I resisted this for a full year before trying it. They add creaminess, fiber, and a hit of plant protein that makes this the highest-protein smoothie on the entire list — and you cannot taste them at all under the chocolate and peanut butter. This is your mic drop.

The Bottom Line on Peanut Butter Protein Smoothies

Every single smoothie on this list proves the same point: eating for protein doesn’t have to mean eating joylessly.

Pick one recipe from this list — just one — and make it tomorrow morning. Not next week. Tomorrow. Set your ingredients out tonight if that helps. Once you nail the first one, the habit builds itself.

The best smoothie is the one you’ll actually make again. And if that one happens to have peanut butter in it, you’ve already won.
