What is a keto fat bomb?

If you remember the low-fat diet trend in the ’80’s, you might be appalled at the idea of trying to purposely increase the amount of fat you eat with the idea of losing weight. However, some people on a ketogenic diet may need a little extra fat to help balance their macros. This is where the “fat bomb” comes in.


A fat bomb is a keto-friendly snack that can give a boost of energy to someone who eats a keto diet. They are generally quick and easy to grab and can help you stay on plan as they can replace higher carb snacks.


Eating extra fat can be helpful to those who have just started eating a keto diet. The more available fats can make it easier for the body to learn how to burn fat and gives a bit of extra fuel to help “prime the pump.” 


Fat bombs can also be helpful to give those who need extra energy–especially if weight loss is not your goal. Those who eat a ketogenic diet for health reasons other than weight loss might need to eat a very high percentage of fat. For example, some doctors and nutritionists advise those using a keto diet to prevent seizures to eat 75% fat. Fat bombs can help them get to these macros. 


If you have chosen a keto lifestyle to lose weight, be sure to keep in mind that you want to burn body fat and not just the fat you are eating. If you find that you’re having trouble losing weight, too much fat and/or total calories could be part of the problem.


How to garnish these keto fat bombs

These peanut butter truffles can be enjoyed without any garnish at all, or you can use your imagination to create the truffle of your dreams! I like to add a bit of chocolate on top. Sometimes I use keto-friendly chocolate chips, If I don’t have chips, I might chop up some chocolate into small chunks. Another option, and what you see in the photos, is to make little chocolate curls by running a vegetable peeler on the side of a low-carb chocolate bar.


If you’re feeling ambitious, you can melt the chocolate and drizzle it over the truffles using a spoon or a pastry bag with a fine tip. This option may bring out your inner Jackson Pollock!

What Peanut Butter do I use for these keto fat bombs?

Peanut butter can be loaded with sugar, so I always check the nutritional label before buying. In addition to avoiding sugar, I try to watch out for artificial sweeteners such as aspartame, and trans-fats. I personally don’t mind palm oil or coconut oil. These can help emulsify the peanut butter so it doesn’t separate into two layers without adding trans fats.


If you choose the kind of peanut butter that separates, you can use it in this recipe. Just be sure to stir it up well before using it. I have tested this recipe both with the type of peanut butter that separates and the type that doesn’t and the results have been excellent with both.


What dairy products should I choose for these truffles?

While any brand of heavy whipping cream and butter will work in this recipe, I try to use high quality organic grass fed dairy products.  Cows on pasture are happy cows, plus, the grass they are eating adds omega 3 fatty acids to their milk.  


If you prefer using raw dairy products, you can use raw cream in this recipe. However, you will want to make sure it’s a few days old. Very fresh (same day) raw cream can be impossible to whip. I learned this the hard way when I had my own cow.

How do I store these Low Carb Peanut Butter Truffles

I normally store these truffles in sealed container in the freezer. This way, they stay much fresher and last longer. While you can eat them straight from the freezer, I prefer to let them warm up at room temperature for 5 minutes or so. This allows them to soften a bit, giving them a creamier consistency.

Truffle Ingredients

  • ½ cup chilled whipping cream
  • 2 teaspoons vanilla extract divided
  • 8 oz cream cheese softened
  • 1 cup peanut butter check the label for carb-count and artificial sweeteners
  • 2 tablespoons butter room temperature
  • 3 tablespoons powdered stevia erythritol sweetener 2X the sweetness of sugar--adjust amount to taste.
  • low-carb chocolate for garnish (chips, chunks, curls or melted chocolate) optional


  1. Line two baking sheets with parchment or a silicone liner.

  2. In a small bowl, beat the whipping cream until soft peaks form. Add 1 teaspoon vanilla extract and beat until stiff peaks form.

  3. In a separate bowl, beat cream cheese and peanut butter together in a medium bowl until smooth. Add butter, 1 tablespoon of vanilla extract, and sweetener and beat until incorporated.

  4. Fold ⅓rd of the whipped cream into the cream cheese mixture to lighten it. Then fold in the remaining cream.

  5. Spoon even amounts of the truffle mixture onto the prepared cookie sheet in ball shapes. Each ball will be the size of a heaping tablespoon. Add chocolate chips, curls, or chopped peanuts for garnish, if desired. If you are using melted chocolate as a garnish, refrigerate or freeze the truffles for a few hours first.

  6. Truffles can be served immediately (if you like them soft) or stored for later. Store in a single layer in an airtight container. They may be kept in the refrigerator or the freezer. Refrigerated truffles will be softer, and frozen truffles will be more solid. If you choose to freeze them, allow them to soften a few minutes at room temperature to soften slightly.
