Banana & Peanut Butter Smoothie
Everything goes into the blender raw. No cooking, no heating, no prep beyond peeling a banana.
Yogurt, milk, and peanut butter push this glass to 38 grams of protein. Three separate sources, each with a different amino acid profile, and the whole thing is done in the time it takes the blender to finish.

Ingredients
- banana 1
- milk, 2% reduced fat 1 cup
- yogurt, nonfat 0.75 cup
- peanut butter 2 tablespoons
- honey 1 tablespoon
Method
-
Add all the ingredients to the blender and blend until smooth.
-
If the mixture is too thick, add water until desired consistency is reached.
-
Serve immediately.
Use a frozen banana instead of a fresh one. Freezing changes the starch structure and releases less water during blending, which gives the smoothie a thicker, creamier body without adding ice or extra liquid.
Why This Works
Behind this recipe
Is 38g protein in one smoothie too much to absorb?
No. The idea that your body wastes protein above 30 grams per meal is one of the most persistent myths in fitness nutrition. A systematic review of protein dose-response research found muscle-building benefits up to 0.4 grams per kilogram per meal, which puts the effective ceiling well above 38 grams for most adults. This smoothie's protein comes from three sources with complementary amino acid profiles, and your body processes all of it.

Yes. Greek yogurt is strained, which concentrates the protein and reduces the carbs. Swapping in the same amount of Greek yogurt adds roughly 5 to 8 grams of extra protein and makes the smoothie noticeably thicker. The fat content depends on whether you choose nonfat, low-fat, or full-fat Greek yogurt, so check the label if you are tracking macros closely.
Does the honey do anything besides add sweetness?
It does. Honey contains complex sugars called oligosaccharides that your body cannot digest. Those sugars pass through to the gut, where a randomized controlled trial found they selectively fuel Bifidobacterium, one of the key probiotic species in yogurt. The study tested honey against table sugar in the same yogurt and found significantly higher levels of B. animalis with honey. The mechanism is real, though the magnitude depends on whether your specific yogurt contains live cultures.
