🥘 Ingredients

ingredients for easy healthy keto low carb avocado peanut butter smoothie recipe

Peanut Butter: If you’re on the keto diet, be sure to use unsweetened peanut butter. Sugar adds unwanted carbs. Natural peanut butter brands typically avoid sugar but check the ingredient list just in case. If you’re looking to cut calories, powdered peanut butter is a good option but you will lose some of the creaminess.

Unsweetened Cocoa Powder: For an intense chocolate flavor, use dark cocoa powder. If you have a high-speed blender, you could also throw in some keto chocolate chips!

Erythritol: I prefer the taste of this sugar replacement, but you can swap it out with your favorite. A few drops of liquid stevia or monk fruit works great too. Just keep adding until you reach the desired sweetness.

Coconut Oil: Coconut oil makes this easy peanut butter smoothie oh-so-creamy!

Avocado: This secret ingredient has a mild taste and creamy flesh perfect for smoothies. It thickens this avocado smoothie recipe, but all you taste is peanut butter flavor! Look for a ripe avocado that gives slightly when you press on it.

Unsweetened Almond Milk: Almond milk has a mild flavor and creamy texture. Be sure to buy unsweetened to avoid added sugar. The almond milk also keeps this recipe plant based, so not only is this shake keto friendly, it happens to be a healthy vegan smoothie too!

Ice: Many smoothies use a frozen banana as a thickener. A fresh banana has over 20 grams of net carbs. Ice cubes add no carbs and thicken it up nicely! A scoop of keto ice cream works well for extra creaminess and to turn this peanut butter avocado smoothie into more of a dessert.

📖 Variations

Healthy breakfasts shouldn’t be boring! Customize this keto chocolate peanut butter smoothie however you please!

  • Milk: Hemp, soy, flax, and coconut milk are all great low-carb options. If you’re not on the keto diet, whole milk works great too. You can also use 1/2 cup of heavy cream and 1/2 cup of water for a super creamy smoothie!
  • Sweetener: Stevia and monk fruit are good options. Start with less because you can always add more but you can’t take it out. For a natural sweetener, try maple syrup or light agave. Keep in mind, any sugar based sweetener wont be low-carb.
  • Nut Butter: Almond butter, sunflower seed butter, and cashew butter are all great options.
  • Protein: Add a tablespoon of chia seeds, flax seeds, hemp seeds, or low-carb protein powder!
  • Greens: I haven’t tested this recipe with greens yet, but my gut says a handful of spinach would blend in nicely.
  • Toppings: Top with keto whipped cream and cacao nibs!

❓ Recipe FAQs

Why do you put avocado in a smoothie?

An avocado is a nutrient powerhouse! They’re rich in fiber, heart-healthy fats, and a variety of vitamins. They also have a creamy and mild flesh that thickens up a smoothie nicely. If you pair the avocado with strong flavors like peanut butter and chocolate, you won’t even know it’s there!

Is peanut butter okay for the keto diet?

Unsweetened peanut butter makes a great addition to the keto diet. Peanut butter is high in fat and protein yet low in carbs. Be sure to avoid added sugar and eat the spread in moderation for best results.

Can I drink smoothies on the keto diet?

Yes, smoothies can be low-carb and delicious! Be sure to avoid smoothies that are packed with fruit juice and high-carb fruits like bananas and mangoes. Instead, look for smoothies with low-carb ingredients like peanut butter, avocado, coconut milk, raspberries, etc. This keto peanut butter smoothie is perfect for a low carb diet!

How do you thicken a smoothie?

There are multiple ways to thicken a smoothie. Ice, frozen fruit, avocado, chia seeds, nut butter, cottage cheese, tofu, and flax seeds are all great options! Alternatively, you can simply add less liquid for a thicker smoothie.

💭 Expert Tips

  • If you don’t have a blender, a food processor will work too!
  • If you’re not on a low-carb diet, you can substitute half of a frozen banana for the ice. This will result in a creamy smoothie with no icy bits.
  • To make your peanut butter chocolate smoothie thicker, start with only 3/4 cup of almond milk.
  • Delicious smoothies are best made fresh! I don’t recommend storing them for later.
  • For a keto milkshake, substitute keto ice cream in place of the ice. Reduce the almond milk to 1/2 cup and then add enough ice cream to make it thick!
