Ingredients
- 1 frozen banana, broken into chunks
- 1 cup unsweetened almond milk (or skim milk)
- 1/2 cup plain nonfat Greek yogurt
- 1 scoop (about 30g) vanilla whey or plant protein powder
- 2 tbsp natural peanut butter
- 1/4 cup rolled oats
- 1/2 tsp vanilla extract
- 1/2 tsp ground cinnamon
- 4–5 ice cubes
- Optional: 1 tsp honey or maple syrup for extra sweetness
Instructions
- 1
Add the almond milk and Greek yogurt to your blender first — liquids at the bottom help everything blend smoothly.
- 2
Add the oats and let them soak for 1 minute. This softens them so you don't get gritty bits.
- 3
Add the frozen banana, protein powder, peanut butter, vanilla, cinnamon, and ice.
- 4
Blend on high for 45–60 seconds, scraping down the sides once, until the smoothie is thick, creamy, and milkshake-textured.
- 5
Taste and add honey if you want more sweetness. Blend 5 more seconds.
- 6
Pour into a tall glass, top with a drizzle of peanut butter and a few banana slices, and serve immediately with a thick straw.

Frequently Asked Questions
How is this peanut butter smoothie so high in protein?+
Three layered sources do the work: 25g from the protein powder, 12g from Greek yogurt, and 7g from peanut butter — that's 38g of total protein, more than most fast-food breakfast sandwiches.
Can I make a peanut butter smoothie without protein powder?+
Yes — add an extra 1/3 cup Greek yogurt and 2 tablespoons hemp hearts. You'll still hit about 28g of protein, perfect for an easy protein recipe without supplements.
Why use a frozen banana?+
Frozen bananas blend into a thick, ice-cream-like base without watering down the smoothie the way ice alone does. Slice ripe bananas and freeze on a tray for a week-long stash.
Can I meal prep peanut butter smoothies?+
Pre-portion all dry ingredients (oats, protein powder, cinnamon, frozen banana, peanut butter) into freezer bags. In the morning, dump into the blender with milk and yogurt and blend.
Is this a good post-workout smoothie?+
It's ideal — fast-digesting whey, carbs from banana and oats, and healthy fats from peanut butter cover the 3 macro bases for muscle recovery.
What can I add for extra nutrition?+
A handful of spinach (you won't taste it), 1 tablespoon ground flaxseed, or a teaspoon of cacao powder for a PB-and-chocolate twist. Pair with our Protein Pancakes for a giant high-protein brunch.
