This Keto Peanut Butter is a low-carb, no-sugar version of that popular spread, which is also made to fit into a low-carb, keto lifestyle. The problem is that most commercial peanut butters have added sugars, hydrogenated oils, and other unnecessary fillers that can make the carb count rise even higher and completely kick you out of ketosis. The keto version is 100 percent roasted peanuts (and maybe a pinch of salt), which means it’s a natural, creamy spread that comes with a healthy dosage of good fats and protein.

This version is pretty low in net carbs, so it’s an awesome pantry staple for those doing the keto thing. It can be consumed as is, spread over low-carb bread, stirred into smoothies or baked into dessert dishes. Some flavors also include extra MCT oil or flaxseed for added nutrition and energy.

This high-fat, low-carb food is not only tasty, but it is high in nutrients such as fiber, magnesium, and vitamin E, and will curb those cravings with its perfect fat-to-protein ratio, so you’ll be noshing less in between meals and whenever you are cooking with it. With its smooth spread and savoury, nutty flavour, keto peanut butter proves it’s possible to have your comfort food and enjoy it without getting caught in a net. It is a low-carb, guilt-free option that tastes great and offers maintain nutrition and energy.

Ingredients Equipment Method Notes

Ingredients

3 cups roasted peanut unsalted (or raw peanuts roasted at home)
2 table spoons peanut oil or avocado oil (optional, for a smoother consistency)
1/4 tsp salt
2 tbsp Optional powdered erythritol or monk fruit sweetener for a little sweet action
1/2 tsp vanilla extract
1/4 tsp cinnamon

Equipment

High speed food processor
Rubber spatula
Air tight glass jar with lid
A baking sheet
Measuring spoons

Method

Lay raw peanuts spread out on a baking sheet and roast them at 350°F (175°C) for about 10–12 minutes, or until golden and pleasantly fragrant. Let cool slightly.
In a food processor, place peanuts; pulse on high 1 minute or until crumbly, scraping down sides.
Process another 3-5 minutes, scraping down the sides every minute or so, until the peanuts go from crumbs to clumps to a grainy paste and finally a smooth peanut butter.
Add salt, and, if using oil, sweetener or flavorings, then blend 30 seconds longer to combine well.
For chunky peanut butter, stir in ¼ cup chopped peanuts at the end.
Great to use as a low-carb base for keto sweets, or straight from the spoon.

Notes

Transfer to a glass jar and chill for up to 3 weeks.

When you do blend, take your time; heat generated by the whirling blades eases peanut oils out from their esconce without any need for encouragement.

Flavour Profile of Keto Peanut Butter

Nutty & Roasted- The star flavor here is the unsweetened peanut butter, which imparts a nutty, roasty, and rich, earthy vibe.
Sweet & Balanced- We sweeten things up with low-carb sweeteners like erythritol or monk fruit, lending a gentle sweetness that is not so overwhelming that it steals the show from the peanut butter.
Buttery & Slightly Salty- Spreading with butter (or a little more peanut butter) increases the richness. A teaspoon or so of salt cut the sweetness and brought forward the general taste.
Warm Vanilla Notes- There’s good cozy warmth here from a splash of vanilla extract that gently rounds out the nuttiness.
Texture & Mouthfeel- Those treats? They’re typically soft and chewy in the center, subtly crisp at the edge, and instantly dissolve in your mouth, leaving behind that satisfying, rich peanut butter taste.
