Serves: 2 people
What You’ll Need
These simple ingredients create smoothie magic:
- 2 large ripe bananas, peeled and sliced
- 3 tablespoons natural peanut butter (smooth or crunchy)
- 1 cup milk of your choice (dairy, almond, or oat milk work great)
- 1/2 cup plain Greek yogurt
- 1 tablespoon honey or maple syrup
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
- 1 cup ice cubes
- Pinch of salt
- 1 tablespoon ground flaxseed (optional, for extra nutrition)
Choosing the Right Bananas
The secret to an amazing peanut butter banana smoothie starts with selecting perfectly ripe bananas. Look for bananas that are yellow with brown spots – these might not look perfect, but they’re actually ideal for smoothies. The brown spots mean the starches have converted to natural sugars, making your smoothie naturally sweet and eliminating the need for extra sweeteners.
If your bananas aren’t quite ripe enough, you can still use them, but you might want to add a bit more honey to compensate for the lower natural sweetness.
Getting Your Peanut Butter Ready
Natural peanut butter can sometimes be thick and difficult to blend smoothly. To make blending easier, let your peanut butter come to room temperature before using, or give it a quick stir if the oils have separated. If you’re using peanut butter straight from the refrigerator, you can soften it by microwaving for 10-15 seconds.
Both smooth and crunchy peanut butter work wonderfully in this recipe. Smooth creates an ultra-creamy texture, while crunchy adds delightful little bits of peanut throughout the smoothie.
Building Your Smoothie
Add ingredients to your blender in the right order for the smoothest results. Start with the milk at the bottom – this liquid base helps everything blend properly and prevents your blender from working too hard. Add the sliced bananas next, followed by the Greek yogurt and peanut butter.
Pour in your honey, vanilla extract, and cinnamon, then add the pinch of salt. The salt enhances both the peanut and banana flavors, making them taste more like themselves. If you’re using flaxseed for extra nutrition, add it now along with the ice cubes.
Blending to Creamy Perfection
Begin blending on low speed for about 20 seconds to break down the larger pieces, then increase to high speed. Blend for 45 to 60 seconds until the mixture is completely smooth and creamy. The finished smoothie should have no lumps of peanut butter or chunks of banana.
If your smoothie seems too thick, add milk one tablespoon at a time until you reach your preferred consistency. If it’s too thin, add half a frozen banana or a few more ice cubes and blend again.
Taste and Perfect
Stop and taste your smoothie to check the flavor balance. The peanut butter and banana should complement each other perfectly, with neither overpowering the other. If you’d like it sweeter, add more honey gradually. For a stronger peanut flavor, add another tablespoon of peanut butter. Want more banana taste? Blend in half of another ripe banana.
The cinnamon should add warmth without being noticeable as a separate flavor. If you can taste it distinctly, you’ve added too much for this recipe.
Serving Your Smoothie
Pour your peanut butter banana smoothie into tall glasses immediately while the texture is at its peak. The beautiful pale brown color looks inviting, and the thick consistency means it will hold its shape nicely in the glass.
For extra indulgence, top with a dollop of whipped cream, a drizzle of additional peanut butter, sliced bananas, or a sprinkle of chopped peanuts. A dash of cinnamon on top makes for an attractive finishing touch.
Making It Even Better
This basic recipe welcomes creativity and personal touches. Add a tablespoon of cocoa powder for a chocolate peanut butter banana combination that tastes like dessert. Throw in a handful of spinach for extra vitamins without changing the flavor. For coffee lovers, add a shot of cold espresso or a teaspoon of instant coffee powder.
Storage and Make-Ahead Tips
While this smoothie is best enjoyed fresh, you can prepare ingredients ahead of time for quicker morning assembly. Slice bananas and freeze them in portions, or even pre-blend the entire smoothie and freeze it in individual containers. Frozen smoothie portions can be thawed overnight in the refrigerator and given a quick stir before drinking.
This protein-rich smoothie provides sustained energy and makes an excellent breakfast replacement or post-exercise recovery drink. The combination of natural sugars, healthy fats, and protein creates the perfect fuel for whatever your day brings.
