Ingredients
- 2 cups cold whole milk or unsweetened almond milk
- 1/2 cup creamy natural peanut butter
- 2 ripe bananas, peeled and frozen
- 1/2 cup plain Greek yogurt
- 2 tablespoons honey or pure maple syrup
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon sea salt
- 1/2 cup ice cubes (optional, for extra thickness)
- Pinch of cinnamon (optional, for warmth)
- 2 tablespoons chopped roasted peanuts for topping (optional)
- Drizzle of chocolate syrup for serving (optional)
Instructions
- Pour your cold milk into a high-powered blender first. This creates a liquid base that helps everything blend smoothly and prevents your blender from getting stuck.
- Add the creamy peanut butter to the blender on top of the milk. Using natural peanut butter without added sugars and oils gives you the best flavor and texture.
- Break the frozen banana pieces into chunks and add them to the blender. Frozen banana is the secret to achieving that thick, creamy, almost milkshake-like consistency.
- Scoop the Greek yogurt into the blender, making sure to break it up into smaller pieces so it blends evenly throughout the smoothie.
- Add the honey or maple syrup for subtle sweetness. The banana already provides natural sweetness, so we’re just enhancing it gently.
- Pour in the vanilla extract and sprinkle the sea salt over the top. The salt enhances all the flavors and makes the peanut butter taste even more rich and complex.
- Add the optional cinnamon if you’d like a warm, cozy spice note that pairs beautifully with peanut butter.
- If you’re using ice cubes for extra thickness, add them now. This is optional since frozen banana already provides plenty of chill and thickness.
- Place the blender lid securely on top and blend on high speed for 45-60 seconds, until everything is completely smooth and creamy.
- Stop the blender and use a spatula to scrape down the sides if needed, then blend for another 15-20 seconds to ensure everything is fully incorporated.
- Divide the smoothie evenly between two tall glasses, pouring slowly to ensure you capture all the creamy goodness.
- Top each smoothie with chopped roasted peanuts for extra crunch and peanut flavor if desired.
- Add a decorative drizzle of chocolate syrup if you’re feeling fancy, then serve immediately with a sturdy smoothie straw or spoon.
- Enjoy your perfectly blended peanut butter smoothie while it’s at its creamiest and coldest!
Pro Tips
Frozen bananas are absolutely essential to this recipe. They create the thick, creamy base without requiring tons of ice, which can water down your smoothie. Freeze banana slices in advance in a zip-top bag for convenience.
Greek yogurt provides protein and creaminess that regular yogurt cannot match. If you don’t have Greek yogurt, use regular yogurt but reduce the amount slightly as it’s more liquid.
Natural peanut butter works best here, but creamy peanut butter from any reputable brand works wonderfully. Avoid the ultra-sweet varieties with added sugars and oils.
Don’t skip the salt. A pinch of sea salt enhances all the flavors in this smoothie and makes the peanut butter taste even more complex and delicious.
Milk choice matters. Whole milk creates the richest, creamiest result, but unsweetened almond milk, oat milk, or cashew milk all work beautifully. Avoid flavored varieties that compete with the peanut butter.
For a protein boost, add one scoop of vanilla or chocolate protein powder. This is perfect if you’re having this as a post-workout meal.
Make it vegan by swapping Greek yogurt for coconut yogurt or silken tofu, and use maple syrup instead of honey.
For chocolate peanut butter flavor, add two tablespoons of unsweetened cocoa powder and an extra tablespoon of honey.
Prepare frozen banana slices at the beginning of each week for grab-and-go smoothie making. They’ll keep in the freezer for up to three months.
This smoothie is best enjoyed immediately after blending, while it’s at its coldest and thickest. If you need to make it ahead, store it in an airtight container in the refrigerator for up to 24 hours, though separation may occur.
Double the recipe easily for four servings, or scale down to single servings by halving all ingredients. Adjust liquid amounts based on your preferred thickness.
