Ingredients
Method
- Add liquids first. Pour the almond milk into your blender. This helps the blades catch everything evenly.
- Add the creamy ingredients. Spoon in peanut butter and heavy cream or coconut cream.
- Mix in flavor and sweetness. Add protein powder, sweetener, cocoa powder (if using), vanilla, cinnamon, and a pinch of salt.
- Top with ice. Start with 1/2 cup. You can always add more if you want it thicker and frostier.
- Blend until smooth. Begin low, then blend on high for 20–30 seconds until it’s creamy and no chunks remain.
- Taste and adjust. Add more sweetener, ice, or a splash of milk to hit your perfect texture and flavor.
- Serve right away. Pour into a chilled glass. If you want, dust with cocoa or cinnamon for a simple finish.
What Makes This Special
This smoothie uses a smart combo of healthy fats and low-carb ingredients to deliver great taste and staying power. You’ll blend unsweetened almond milk, natural peanut butter, and a bit of heavy cream or coconut cream for richness.
For sweetness, a keto-friendly sweetener brings the flavor together without adding sugar. A scoop of low-carb protein powder helps with texture and keeps you full longer. The result is smooth, frothy, and surprisingly indulgent for something so simple.
Ingredients
- 1 cup unsweetened almond milk (or unsweetened macadamia milk for extra creaminess)
- 2 tablespoons natural peanut butter (no sugar added; look for only peanuts and salt)
- 2 tablespoons heavy cream (or 2 tablespoons full-fat coconut cream for dairy-free)
- 1 scoop vanilla or unflavored low-carb protein powder (whey isolate, egg white, or plant-based)
- 1–2 teaspoons powdered erythritol, allulose, or a few drops liquid stevia (to taste)
- 1 tablespoon unsweetened cocoa powder (optional, for a peanut butter cup vibe)
- 1/2 teaspoon vanilla extract
- 1/8 teaspoon cinnamon (optional, adds warmth)
- Pinch of sea salt (balances flavors)
- 1/2–1 cup ice (adjust for thickness)

Why This is Good for You
- Low in net carbs: Unsweetened milk alternatives, natural peanut butter, and keto sweeteners keep sugars down.
- Healthy fats for satiety: Peanut butter and cream or coconut cream help you stay full and satisfied.
- Protein for balance: A scoop of protein supports muscle recovery and steadier energy.
- Micronutrients: Peanuts bring magnesium and vitamin E; cocoa adds antioxidants if you include it.
- Blood sugar friendly: No added sugar and a solid fat-protein combo help minimize spikes.
What Not to Do
- Don’t use sweetened milk or peanut butter. Added sugars will kick you out of ketosis quickly.
- Don’t skip the salt. A tiny pinch makes the peanut flavor pop and balances the sweetness.
- Don’t overdo the peanut butter. It’s calorie-dense; measure it so your macros stay on track.
- Don’t rely on high-carb thickeners. Avoid bananas, dates, or honey; use ice or a few chia seeds instead.
- Don’t forget to taste as you go. Protein powders vary; adjust sweetener and liquid for a smooth, pleasant sip.
Variations You Can Try
- Mocha Peanut Butter: Add 1 teaspoon instant espresso or 1/4 cup cold brew for a coffee kick.
- Salted Peanut Butter Cup: Use cocoa powder, add an extra pinch of sea salt, and finish with sugar-free chocolate shavings.
- Peanut Butter Berry: Blend in 1/4 cup frozen raspberries or strawberries. Keep portions small to stay low-carb.
- Green Peanut Butter Smoothie: Add a handful of baby spinach. It won’t change the flavor much but boosts nutrients.
- Dairy-Free Dream: Swap the heavy cream for coconut cream and use a plant-based protein powder.
- Extra Thick: Add 1–2 teaspoons chia seeds and let the smoothie sit for 5 minutes before drinking.
- Lower Calorie: Reduce peanut butter to 1 tablespoon and skip the cream; add more ice for volume.
- Almond or Cashew Twist: Replace peanut butter with almond or cashew butter if you prefer the flavor.
FAQ
Is Peanut Butter Keto?
Yes, in moderation.
Natural peanut butter with no added sugar fits into a keto diet thanks to its low net carbs and healthy fats. Just watch your portion size because calories can add up quickly.
What’s the Best Sweetener for This Smoothie?
Allulose and erythritol are great options that blend smoothly and taste close to sugar. Liquid stevia works too, but add it drop by drop to avoid bitterness.
Choose what you like and adjust to taste.
Can I Make It Without Protein Powder?
Absolutely. Skip the protein powder and add a few ice cubes plus an extra teaspoon of peanut butter for body. The texture will be slightly lighter, but still creamy and satisfying.
How Many Carbs Are in This?
Exact numbers depend on your brands and portions, but most versions land around 5–8 grams net carbs per serving.
Use unsweetened milk, natural peanut butter, and a low-carb protein powder to stay on target.
Can I Use Powdered Peanut Butter (PB2)?
You can, but check the label for added sugar. Powdered peanut butter lowers calories and fat, which may reduce creaminess and satiety. If you use it, add a little more cream or a few chia seeds to keep the texture lush.
What If I Don’t Have Almond Milk?
Use unsweetened macadamia, cashew, or coconut milk from a carton.
Avoid regular dairy milk, which is higher in lactose and carbs.
How Do I Make It Even Creamier?
Add an extra tablespoon of heavy cream or coconut cream, or toss in 1/4 of a ripe avocado. Blend well for a silky, milkshake-like finish.
Will This Work as a Meal Replacement?
Yes, if you include protein powder and enough fat. For a fuller meal, add a teaspoon of MCT oil or a small handful of hemp hearts to boost calories and satiety.
