Easy Peanut Butter Banana Smoothie With Protein

Nothing goes better together than peanut butter and bananas. Smoothie drinkers love the combination of salty peanut butter and sweet bananas. The healthy combination of fruit and healthy fat is prime for a weight gain smoothie. 

A peanut butter banana smoothie is a perfect recipe to break your hunger and keep you full for hours. The thick and creamy shake resembles a milk shake, but healthier. The JuicingJournal team will often break a fast with this smoothie because it is so filling!  Manu reads also use it as a “bulking” option for post workout recovery.

Peanut Butter in Weight Gain Smoothies

Peanut butter is a common weight gain and bulking ingredient. When blended into a smoothie, it adds a creamy and rich element to the drink. Peanut butter is high in healthy fat and protein, which will keep you full for hours. Two tablespoons of peanut butter can contain up to:

  • 200 calories
  • 10 grams of protein
  • 30% DV of Niacin
  • 3 grams of fiber
  • 20 grams of fat
  • 10% DV of Vitamin E

Bananas in Weight Gain Smoothies

Bananas are a great complement to the tase of peanut butter. Bananas are a refreshing and light fruit that balances out the heavy and thick tase of peanut butter. Bananas blend well in smoothies due to their soft squishy texture. Many smoothie enthusiasts enjoy using frozen bananas to give their peanut butter banana smoothie an icier texture without using a lot of ice. 

Bananas are an excellent source of nutrients to help you gain wait in a healthy fashion. The versatile fruit is packed with potassium, natural sugar, fiber, and Vitamin C. It is easy to see how adding a banana to your smoothie puts this super-fruit to work for you. A single banana can easily provide you with the following nutrients:

  • 95 calories
  • 13 grams of natural sugar
  • 13 grams Vitamin C
  • 3 grams of fiber
  • 410 grams of Potassium
  • 30 grams of carbs

Preparation for a Peanut Butter Banana Weight Gain Smoothie

I want to walk you through how best to make the perfect peanut butter banana smoothie. It begins by prepping your ingredients the right way.

Freeze Bananas

If possible, freeze the bananas the night before making the smoothie. Using frozen fruit will allow you to get the icy texture of a smoothie without using as much ice. Using less ice will allow for the natural flavors of the banana and peanut butter to shine. Ice can dilute the natural flavors of your smoothie.

Pre-measure Milk, Honey, and Peanut Butter

Pre-mixing your milk, honey, and peanut butter will save you time in the smoothie making process.  If you plant to make the peanut butter banana smoothie several times, you can pre-mix the liquid ingredients for the coming days.

Use Crushed Ice If Possible

Using crushed, or nugget, ice will allow for a smoother blend of the ingredients.  Traditional cubed ice can result in larger chinks of ice in the smoothie. Using a strong blender can help to break down the smaller ice chunks, if crushed ice is not available. 

Weight Gain Smoothie Options

If gaining weight is your goal, there are several options that you can substitute to add calories and fat. Adding extra calories will allow you to gain weight quicker and in a healthier fashion. Using regular peanut butter, whole milk, and honey will add the necessary calories for weight gain. 

Whole Milk

whole milk

Whole milk is high in fat and calories. One cup of whole milk can contain up to 150 calories and 8 grams of fat. 8 grams of fat will put you well on the road to your weight gain goals.

JuicingJournal always encourages using whole milk to reach weight gain goals. 

Regular Peanut Butter

Peanut butter is offered in several different varieties. Traditional peanut butter is what you want if you are looking to add calories and fat. Regular peanut butter can contain up to 100 more calories and 8 more grams of fat than some low-fat options. Adding additional peanut butter to your peanut butter banana smoothie is an easy way to add nutrients and calories.

JuicingJournal always recommends adding additional peanut butter after all of the other ingredients have been mixed together. Peanut butter can overwhelm the other flavors of the smoothie. It is important to remember: “You can always add more, but you can’t take it out once it is mixed in.”


Natural honey is an excellent source of sweetness and calories. One tablespoon of honey contains up to 75 calories. The Juicing Journal editorial team always recommends using honey instead of refined sugar for sweetness. 

Chia Seeds

Chia seeds are often found in healthy smoothie recipes. Chia seeds are packed with nutrition despite their tiny size. Two tablespoons of chia seeds can add the following nutrients to any smoothie recipe:

  • 104 Calories
  • 5 Grams Protein
  • 10 Grams Fiber
  • 15% Daily Calcium
  • 25% Daily Magnesium
