A creamy banana and peanut butter smoothie is my favorite way to start the morning with energy and a smile. This recipe comes together with just a handful of ingredients and delivers a thick nourishing blend that keeps you fueled for hours. Kids love it adults crave it and it is even better for those busy days when a quick nutritious boost is all you need.
The first time I tossed peanut butter into my blender with banana I was amazed how dessert-worthy it tasted while being so good for me. Now I throw this together every week usually as a post-workout treat or afternoon pick-me-up.
Ingredients
- Ripe banana: Brings natural creamy sweetness and helps with the smoothie’s thick texture. Choose one with plenty of brown speckles for maximum flavor.
- Creamy peanut butter: Adds protein and richness. Use a smooth variety and check ingredients for pure peanuts with little or no added sugar.
- Milk: Helps everything blend together nicely. Use dairy or your favorite plant-based milk like almond, oat, or soy for extra nutrition.
- Ice: Makes the smoothie cold and frothy. Blend in extra ice cubes if you love it thicker.
Step-by-Step Instructions
- Peel and Prepare the Banana:
- Slice one large ripe banana into pieces. This helps the blender create a super silky base and intensifies both sweetness and creaminess.
- Measure the Peanut Butter:
- Scoop two full tablespoons of creamy peanut butter. Use the back of a spoon to scrape every last bit into the blender.
- Add Milk and Ice:
- Pour in one cup of milk and toss in a generous handful of ice cubes. The milk keeps everything smooth while ice gives the blend that cool frosty texture.
- Blend Until Silky:
- Secure the blender lid and blend on high for a full minute. Stop halfway to scrape down the sides and check for any unblended chunk. Keep blending until perfectly smooth and pourable.
- Taste and Adjust:
- Dip in a spoon for a taste. If you want it sweeter, add half a banana more. If it is too thick, a splash more milk does the trick.
- Pour and Enjoy:
- Pour into a tall glass and sip right away. For extra flair, garnish with banana slices or a sprinkle of chopped peanuts.

Toasted peanut butter is my secret touch when I am craving something extra special. It gives the smoothie a warm nutty flavor that reminds me of summer afternoons spent baking peanut butter cookies with my grandma. Sometimes we would freeze banana slices ahead and add them to our smoothies making them even creamier.
Storage Tips
This smoothie is best enjoyed straight from the blender for peak texture and flavor. If you do need to make it ahead, keep it sealed in a jar in the fridge for up to one day. Give it a good shake before sipping or re-blend if it separates. Sometimes I even freeze leftovers as popsicles for an easy treat.
Ingredient Substitutions
Swap in almond or cashew butter for a new twist on flavor. Use oat milk or coconut milk to keep it dairy free. If you are out of fresh banana, frozen slices work beautifully. Just throw them in and reduce the ice.
Serving Suggestions
Top with granola, crunchy seeds, or a drizzle of honey for extra interest. At parties, I love serving this in shot glasses as an energizing mini-dessert. Kids can decorate their own with chocolate chips and a swirl of extra peanut butter.
Cultural and Historical Context
The pairing of banana and peanuts has roots in southern comfort food and shows up everywhere from sandwiches to milkshakes. The smoothie twist took off as home blenders got more popular, giving everyone an easy way to enjoy these classic flavors without any fuss.
