Delicious protein shakes (and smoothies) are easy to make at home using easy-to-find ingredients. While protein powders are always an option, some find the flavor off-putting. A simple combination of peanut butter and banana makes for a winning flavor, and protein-filled whole foods like rolled oats, nuts or nut milks, and seeds also provide a nutrient boost. Following the shake recipe below yields 21 grams of protein, and you can always customize the shake if more protein is needed.

Things You'll Need

  • 1 ½ large ripe bananas, peeled and frozen

  • 2 tablespoons peanut butter (see note)

  • 1 cup unsweetened almond milk

  • 1/3 cup rolled oats

  • 1/8 teaspoon ground cinnamon, optional

  • 3 to 5 ice cubes

Ingredient Notes

  • Any type of peanut butter can be used in a shake or smoothie, including crunchy, creamy, sweetened, or unsweetened. If using an unsweetened peanut butter, you may consider adding a small amount of honey to sweeten the shake.


Video of the Day

  • Because there is protein in peanut butter, almond milk, and oats, it's not necessary to add protein powder, but you certainly can if you'd like. Choose a protein powder with few additives and low or no sugar in order to keep this shake clean and healthful.
  • Consider adding chia seeds or hemp seeds (or hemp powder), or whole raw nuts like almonds, walnuts or pecans to boost the nutrient level of this shake.


  • Any non-dairy milk, such as coconut milk, cashew milk or soy milk can be used to replace the almond milk. You can also use regular dairy milk.
  • In addition to peanut butter, you can make protein shakes using almond butter, cashew butter, sunbutter, etc.


  • A dash of cinnamon and even a tiny amount of pure vanilla extract are optional for enhancing the flavor of a peanut butter and banana protein shake.

Step 1: Gather Your Ingredients

Gauge and measure your ingredients depending on the level of protein and sweetness you're looking for. For more protein, add more peanut butter, or a scoop of protein powder. For a sweeter shake, add a small amount of pure maple syrup, honey, fresh figs, or pitted dates.

Step 2: Blend Ingredients

Add all of the ingredients for the shake to a high-powered blender. Blend until completely smooth. If necessary add more almond milk to help blend the ingredients. Note: As the shake sits, it will become thicker and creamier because of the oats.

Step 3: Enjoy!

Before pouring the shake into a glass, you can taste it for flavor. If you'd like, add more peanut butter, banana, almond milk, or a sweetener like honey to taste, and blend again until combined. Pour shake into a tall glass, and enjoy!


Serve and enjoy
