Peanut butter was one of the first things I looked up when I started keto years ago. Good news: natural peanut butter is fine on keto. Better news: there are more ways to use it than most people realize.
Most people think keto peanut butter recipes stop at fat bombs and no-bake balls. That’s a small corner of it. I’ve used peanut butter in ice cream, Thai-style chicken sauce, meringue cookies, mug cakes, tarts, and fudge bars that sit in my freezer and disappear faster than I’d like to admit. The Classic Peanut Butter Cookies on this list are down to just three ingredients and under 2g net carbs per cookie. I’ve made them probably 40 times by now.
These are the ten peanut butter recipes I come back to most. Some are desserts. One’s dinner. A couple are good for meal prep. If you’re new to keto and trying to figure out how to handle sweet cravings without blowing your carbs, start here.

1. Keto Peanut Butter Fudge Bars
Per serving: 342 cal | 33.0g fat | 5.7g net carbs | 7.3g protein
Chocolate and peanut butter layered into a bar that sets up firm in the freezer and holds together when you grab one out of the bag. The texture is closer to fudge than a protein bar, dense, with a silky peanut butter center. I keep a batch wrapped individually in the freezer so I’m not standing in front of the fridge looking for something.
Peanut butter brings a solid amount of monounsaturated fat to these, which may help support healthy cholesterol levels. At 342 calories and 33g fat per bar, they’re filling enough that one is usually enough.
2. Tasty Keto Peanut Butter Cups Recipe
Per serving: 198 cal | 18.6g fat | 8.0g net carbs | 4.4g protein
Three-ingredient chocolate shell over a peanut butter center: same concept as the candy, different execution. The chocolate sets up firm and snaps when you bite into it. Straightforward to make and gone in about two days in my house.
3. Classic Peanut Butter Cookies
Per serving: 92 cal | 8.3g fat | 1.4g net carbs | 2.8g protein
Three ingredients: peanut butter, egg, sweetener. That’s the whole recipe. The texture is crumbly with a bit of chew, and the fork-press pattern on top actually matters: it’s not just for looks, it helps them bake evenly. At 1.4g net carbs each, I’ll usually have two without thinking twice about it.
If you’re using a natural peanut butter, stir it thoroughly before measuring: oil separation changes the texture of the finished cookie. I learned that the hard way the first time I grabbed a jar that had been sitting a while and didn’t bother stirring.
4. Peanut Butter and Chocolate Chunk Mug Cake
Per serving: 500 cal | 46.8g fat | 6.8g net carbs | 13.5g protein
One mug, one minute and thirty seconds in the microwave, and you’re done. I used to skeptical of mug cakes: most of them come out rubbery. This one actually works. The chocolate chunks stay soft and the peanut butter flavor carries all the way through. There’s no getting around the calorie count at 500 per serving, but it’s a single serving and it’s filling.
5. Keto PB & Chocolate Cottage Cheese Ice Cream
Per serving: 224 cal | 14.4g fat | 6.7g net carbs | 15.3g protein
Peanut butter, cocoa powder, and cottage cheese blended until smooth, then frozen. The cottage cheese is what makes it work: it churns into something that actually scoops like ice cream instead of freezing into a solid block. The texture surprised me the first time. I was expecting it to be icy and grainy.
Cottage cheese adds about 15g of protein per serving here, which pushes the protein-to-calorie ratio higher than most keto desserts. It’s also a source of casein, which digests slowly and may help with satiety for a few hours after eating.
6. Thai Style Low Carb Peanut Chicken
Per serving: 409 cal | 28.6g fat | 4.5g net carbs | 36.9g protein
This is peanut butter used in a completely different context, a Thai-style sauce over chicken with citrus and chili. The sauce is earthy and slightly sharp, not sweet. Serve it over cauliflower rice or just straight from the pan.
7. Keto Chocolate Puppy Chow
Per serving: 522 cal | 42.0g fat | 6.7g net carbs | 23.9g protein
Puppy chow is one of those childhood snacks that sounds completely keto-incompatible, but this version swaps in low-carb chocolate and peanut butter puffs instead of cereal. The coating is light and dry, and the pieces stay separate once cooled. It works well for a casual snack situation when you want something with texture rather than something rich.
8. Keto Almond Protein Breakfast Balls
Per serving: 428 cal | 34.8g fat | 4.7g net carbs | 21.7g protein
I make these on Sunday when I know the next few days are going to be rough. Six minutes to put together, and you have four servings of something filling with 21g protein each. They’re denser than they look: almond butter, protein powder, and a coating that crisps up slightly in the freezer. My buddy tried one when he stopped by last week and texted me for the recipe the next morning.
9. LC Peanut Butter Meringue Cookies
Per serving: 49 cal | 3.6g fat | 1.1g net carbs | 3.3g protein
Three ingredients: egg whites, powdered sweetener, peanut butter. They bake up light with a thin crisp shell and a soft center, nothing like a regular cookie. Good if you have leftover egg whites from another recipe.
10. Keto Chocolate Peanut Butter Tarts
Per serving: 331 cal | 28.4g fat | 5.0g net carbs | 9.0g protein
Small tarts with a chocolate shell and a thick peanut butter filling. More filling than dessert, at 331 calories and 28g fat each, one is legitimately enough. The crust holds up better than most keto pastry shells.
Peanuts are one of the better dietary sources of biotin, copper, and manganese, minerals that tend to go overlooked on keto. Worth keeping in rotation for more than just the taste.

Frequently Asked Questions
Is peanut butter keto-friendly?
Natural peanut butter, the kind with just peanuts and salt, is fine on keto. Two tablespoons run around 3-4g net carbs, which fits easily into most daily targets. The issue is commercial brands with added sugar or partially hydrogenated oil. If you’re just getting started, the keto food list covers which nut butters to keep and which to skip.
How much peanut butter can I eat on keto per day?
It depends on your total carb target for the day. Most people doing keto aim for under 20-30g net carbs, and two tablespoons of natural peanut butter is about 3.5g net carbs, so you have room. The bigger thing to track is calories, since peanut butter is calorie-dense. Use the keto calculator to figure out your specific fat and protein targets before deciding how much to work in.
What can I substitute for peanut butter in keto recipes?
Almond butter and sunflower seed butter both work well as direct swaps in most of these recipes. Almond butter is slightly lower in carbs. Sunflower seed butter is a good option if peanuts are a problem: the macros are similar. Check the complete keto food list for a breakdown of nut and seed butter options.
Can keto peanut butter cookies really have under 2g net carbs?
Yes, the three-ingredient version on this list (peanut butter, egg, sweetener) comes in at 1.4g net carbs per cookie. The key is using a powdered erythritol or allulose sweetener, which doesn’t add to the net carb count. If you’re new to keto baking and want to understand how sweeteners work in recipes, the keto sweeteners guide breaks it down.
Are keto peanut butter desserts good for meal prep?
Most of the recipes on this list hold up well for several days. The fudge bars and protein breakfast balls do best stored individually wrapped in the freezer: grab one when you need it. The cookies can sit at room temperature for 3-4 days in a sealed container. For a full approach to keto meal prep, the keto meal plan shows how to build a repeatable weekly structure.
Putting It All Together: Keto Peanut Butter Recipes
If you’re starting from scratch, make the Classic Peanut Butter Cookies first: three ingredients, hard to get wrong, and a good reference point for what keto baking can do. From there, the Fudge Bars and Protein Breakfast Balls are worth having in rotation for something you can grab without thinking. The Thai Peanut Chicken is the one to try if you want to see peanut butter working as a savory sauce rather than a dessert ingredient.
