Choosing the Best Ingredients

Bananas

Use bananas with plenty of brown spots on the peel. These bananas are naturally sweeter and blend into a creamier texture. Frozen bananas make the smoothie thicker and colder without needing much ice.

Peanut Butter

Natural peanut butter provides a richer peanut flavor. Smooth peanut butter creates the creamiest drink, while crunchy peanut butter adds tiny bits of texture.

Milk

Whole milk gives the richest consistency. Low-fat milk makes the smoothie lighter. Almond, oat, soy, or coconut milk also work well and each adds a different flavor profile.

Sweetener

Taste the bananas before adding sweetener. If they are fully ripe, extra sweetener may not be necessary.

Step-by-Step Instructions

Step 1

Wash your hands and gather every ingredient and piece of equipment. Having everything ready makes the preparation faster and keeps the process organized.

Step 2

Peel the bananas. Slice them into several pieces so they blend more easily. If using frozen bananas, allow them to soften for just a minute or two before blending.

Step 3

Pour the milk into the blender first. Adding liquid before the solid ingredients helps the blender operate more smoothly.

Step 4

Add the banana pieces.

Step 5

Add the peanut butter.

Step 6

Pour in the vanilla extract.

Step 7

Sprinkle in the cinnamon.

Step 8

Add honey or maple syrup if desired.

Step 9

If using oats, yogurt, chia seeds, flaxseed, cocoa powder, or a pinch of salt, add them now.

Step 10

Add the ice cubes.

Step 11

Secure the blender lid tightly.

Step 12

Blend on low speed for about 20 seconds.

Step 13

Increase to high speed and blend for another 60 to 90 seconds until completely smooth.

Step 14

Stop the blender and check the consistency.

Step 15

If the smoothie seems too thick, add a little more milk and blend again.

Step 16

If it seems too thin, add another half banana or a few ice cubes and blend again.

Step 17

Taste the smoothie.

Step 18

Adjust sweetness, cinnamon, or peanut butter according to your preference.

Step 19

Blend one final time for about 15 seconds.

Step 20

Pour into chilled serving glasses.
