When it comes to choosing between cashew butter and peanut butter, do you find yourself wondering which one is the better choice? Both nut butters are delicious and offer unique nutritional benefits, making them popular choices for spreads, snacks, and cooking ingredients.

Nutritionally speaking, cashew butter and peanut butter are very similar in calories and fat content. The biggest difference between the two is that peanut butter has more fiber and protein and less carbs. Cashew butter contains higher amounts of iron, magnesium, and vitamin B6 and peanut butter contains more vitamin E, vitamin B6, and calcium.

Another determining factor of which nut butter I choose is obvious – the taste. This is one area where I find the two differ greatly. Cashew butter has a creamier consistency and a milder, slightly sweeter taste whereas peanut butter has a bolder flavor and a much thicker texture. Your tastebuds will be the judge of who you feel the winner is for sandwiches, snacks, and recipes.

Ingredient Comparison

When I am deciding which nut butter is best for me, I first want to examine the nutritional content.


Let’s first examine the macronutrients of these two popular nut butters:

  • Calories: Cashew butter and peanut butter are fairly similar when it comes to caloric content, with only minor differences depending on serving size and brand.
  • Protein: Peanut butter has a slightly higher amount of protein than cashew butter, making it a better choice if you want to increase your protein intake.
  • Fats: Both cashew and peanut butter are high in fat content but have a high dose of heart-healthy monounsaturated fats.
  • Carbohydrates: Cashew butter has more carbohydrates than peanut butter.


Now let’s compare the micronutrients in cashew butter and peanut butter:

  • Magnesium: Cashew butter is a rich source of magnesium, containing almost 100 milligrams more than peanut butter per serving.
  • Iron: Cashew butter also has a higher iron content per serving, containing almost 5 times more than peanut butter.
  • Vitamin B6: Both nut butters contain vitamin B6, but peanut butter contains two times more than cashew butter.
  • Calcium: Peanut butter contains a slightly higher amount of calcium than cashew butter per serving.

In summary, both cashew butter and peanut butter are healthy choices. Peanut butter is superior in protein and fiber, while cashew butter offers higher levels of micronutrients like magnesium and iron.

Nutritional Comparison

Best for Calorie Content

When comparing cashew butter and peanut butter, their calorie content is relatively similar. One tablespoon of cashew butter contains approximately 94 calories, while the same amount of peanut butter contains about 96 calories. This makes both nut butters almost equal in terms of calorie content.

Best for Carbs & Sugar Content

Cashew butter and peanut butter are similar in carb and sugar content but cashew butter is the winner in the category. One tablespoon of cashew butter has 4.4g of carbs and peanut butter has 3.6g. The biggest difference between these two is the sugar content. Cashew butter contains zero sugar whereas peanut butter has almost 2 grams per tablespoon.

Best for Protein Content

Both cashew butter and peanut butter contain protein but for this comparison, the winner is peanut butter. One tablespoon of peanut butter has approximately 3.6g of protein, whereas cashew butter contains around 2.8g.

Best for Fat Content

When it comes to fat content, there is only a marginal difference between these two nut butters. Cashew butter contains slightly more total fat, with 7.9g per tablespoon compared to peanut butter’s 8g. Peanut butter has a higher amount of saturated fat (1.6g) than cashew butter (1.4g), however, they both contain 4g of monounsaturated fat per tablespoon.

Best for Fiber Content

Neither cashew butter nor peanut butter are powerhouses when it comes to fiber but peanut butter does have slightly more fiber than cashew butter. One tablespoon of peanut butter contains about 0.8g of fiber, while cashew butter has only 0.3g.

Best for Sodium/Salt Content

Here again, these two nut butters are comparable. A tablespoon of either cashew butter or peanut butter contains a little over 2g of sodium. In this comparison there really is no clear winner however, if you are someone who needs to monitor your salt intake, look for a nut butter that does not have any added sodium.

Best for Vitamins/Minerals

Cashew butter contains a higher amount of iron and magnesium than peanut butter. Peanut butter contains more calcium, vitamin B6, and vitamin E, and niacin. Both of these nut butters offer varying degrees of health benefits.

Best for Flavor/Texture

Cashew butter and peanut butter may be similar in a lot of ways, but they are very different when it comes to flavor and texture. You will ultimately have to be the judge of who this winner is. But here are some general differences between these two that you may find helpful in making your decision.

Cashew butter has a slightly sweet taste. The higher fat content gives the texture a smooth, creaminess. Peanut butter has a more distinct taste, but it, too, is smooth and creamy. If you prefer more texture in your nut butters, you can choose a peanut butter that has actual pieces of peanut in the butter.

Here are some factors to consider when deciding which nut butter is the best fit for your flavor and texture preferences:

  • Sweetness: Cashew butter has a natural sweetness, while peanut butter is generally less sweet, with some brands adding sugar.
  • Texture variations: Peanut butter comes in both smooth and crunchy varieties, while cashew butter is typically creamy and smooth.
  • Richness: Due to its higher fat content, cashew butter may be perceived as richer or more decadent.
  • Pairings: Cashew butter has a milder taste, making it an excellent choice for both sweet and savory dishes. Peanut butter has a stronger taste, making it a better choice for international dishes such as Chicken Satay, Thai Peanut Sauce, or simply in your smoothie or as the classic peanut butter and jelly sandwich.

Cashew butter and peanut butter are both winners. Give them both a taste and see which one is the winner for you and your family.

Allergies and Sensitivities

If you are like me and have a family member with a nut allergy, you know how serious the matter is. Allergic reactions vary greatly from person to person so it is extremely important to closely examine the potential allergens with both cashew butter and peanut butter.

Peanut Allergies

Peanut allergies are more common than cashew allergies. If you have a peanut allergy, it’s crucial to avoid peanut butter and any products containing peanuts. Some symptoms of peanut allergies include:

  • Hives or redness on the skin
  • Swelling, particularly of the face and throat
  • Difficulty breathing or wheezing
  • Gastrointestinal issues, such as vomiting or diarrhea

In severe cases, a peanut allergy can cause a life-threatening condition called anaphylaxis. This is a severe immune response to the allergen that can cause difficulty breathing and requires immediate medical attention.

Cashew Allergies

Cashew allergies are less common but can still cause similar reactions to peanut allergies. If you are allergic to cashews, it is essential to avoid cashew butter and any products containing cashews. Symptoms of cashew allergies can include:

  • Skin reactions, such as hives or redness
  • Swelling of the face, lips, or tongue
  • Respiratory problems, like difficulty breathing or wheezing
  • Gastrointestinal issues, like vomiting or diarrhea

As with peanut allergies, a severe reaction with a cashew allergy can cause anaphylaxis and requires immediate medical attention.


Keep in mind that if you are allergic to one type of nut, there is a possibility of cross-reactivity with other types of nuts. This means that if you have a known allergy to peanuts, you might also have a sensitivity or allergy to cashews, and vice versa. If you are unsure about your nut allergy status, it’s best to consult an allergist or medical professional before including nut butters in your diet.
