This Keto Peanut Butter Smoothie is a smooth, velvety, incredibly delicious recipe that will satisfy your urge to start indulging in keto-friendly treats with the nutty taste of peanut butter. And unlike some other smoothies, which might rely on bananas or sweetened milk to give them some bulk, it goes all-in on healthy fats and non-sugary add-ins to keep carbs low and intensity high.
The base consists of unsweetened almond milk or coconut milk, mixed with natural, unsweetened peanut butter for a nutty, rich flavor. Cream cheese or heavy cream can enhance the creamy factor, and cocoa powder and vanilla extract make it taste like dessert. To pack in even more nutrition and keep hunger at bay, many shakes call for chia seeds, flaxseeds, or a scoop of protein powder.
This is a versatile smoothie—it is just as good plain as it is as a chocolate-peanut butter twist, and does well with an avocado or spinach addition to beef up the nutrition without changing the flavor profile too much. Sweetness is dialed with keto-friendly alternatives such as monk fruit or stevia.
Great for breakfast, a post-workout fuel up, or a sweet treat replacement, get your fill of healthy fats, protein, and taste, all in a glass with the keto peanut butter smoothie! It’s the perfect filling and decadent drink, which will have you buzzed and within keto macro values.
