Keto Peanut Butter Cup Fat Bombs


Fat bombs are the bomb! Not only are they super easy to make but their low-carb, high-fat content is great for avoiding a blood sugar spike.
Keto fat bombs are usually made from a high-fat base of nut butter, coconut oil, avocados or cream and then flavored and sweetened with some low-carb goodies. The fat in this recipe comes from peanut butter and coconut oil.
Following a ketogenic diet can be challenging sometimes. That’s where these peanut butter fat bombs come to save the day. They make snacking on a keto diet easy and stress-free.

What’s a fat bomb?

Fat bombs were originally designed for followers of a ketogenic diet. They are basically a mixture of ingredients filled with healthy fats. These ingredients are mixed together and then poured in a miniature muffin tin to form delicious bite-sized treats.
These chocolate peanut butter bites basically taste like a mix between peanut butter cups and fudge! They’re made up of peanut butter, coconut oil, cocoa powder, and stevia (a keto-friendly sweetener).

How do fat bombs help you lose weight?

First, let’s back up. To follow a ketogenic diet, it’s recommended to eat high fat and low carb foods. This is supposed to induce ketosis which is a state where the body begins to burn fat for fuel instead of carbs.
So when in the state of burning ketones (called ketosis) these fat bombs will provide an extra boost of fat calories that will aid the body in remaining in ketosis. They are also a great energy booster and can help you fight sugar cravings.

Why use fat bombs on keto diet?

They are high in fat (and low in protein) that they allow the body to burn more fat for fuel and help the body remain in ketosis.
They can provide essential healthy fats that may be lacking in a low-carb diet.
They also can provide an extra boost of energy as a low-carb diet can be initially hard on your energy levels.

How many fat bombs can you eat on keto?

That is completely contingent on how much additional fat is needed in an individual’s daily diet. While following the Keto diet, it’s recommended that daily macronutrients (fats, carbs, & proteins) are carefully tracked. So, these chocolate peanut butter bombs can be consumed if individual fat consumption levels haven’t been hit for the day. They can also be factored into daily meal (and macronutrient) planning.

How to make keto peanut butter fat bombs?

These peanut butter fat bombs pack a powerful amount of energy and they can easily be made and stored for the week ahead, making them the perfect on-the-go snack.
Step 1: Mix together the coconut oil, peanut butter, salt, vanilla extract, and an no-calorie sweetener in a small mixing bowl until it is smooth and creamy.
Step 2: Divide the mixture between muffin paper cups . Place them in the refrigerator for at least an hour, or overnight, to set.
Step 3: While the peanut butter fat bombs are chilling, it’s time to make the chocolate ganache! Simply whisk together all of the ganache ingredients until a silky smooth chocolate ganache comes together.
Step 4: Spoon the chocolate ganache over the chilled peanut butter fat bombs (it was roughly 1 tablespoon of chocolate ganache per fat bomb). Chill in the refrigerator until the ganache has set.
Step 5: Serve straight from the fridge so the fat bombs don’t melt.

How to make the perfect peanut butter fat bombs?

  1. You can substitute the peanut butter for any other smooth nut butter that has no added salt or sugar. It will still work perfectly and you can then experiment with different tastes. Always replace the nut butter in a ratio of 1:1. 
  2. The flavors of these peanut butter fat bombs can be experimented with in many ways. Not only can you change the nut butter used, but you can also use an edible essential oil like peppermint or orange to bring out the chocolate ganache flavoring. Use 1 – 2 drops of the flavored oil to give your fat bombs a unique spin!
  3. As these fat bombs are made with mainly coconut oil and peanut butter, they need to be stored in the refrigerator. Leaving them out at room temperature for too long will only result in a puddle of peanut butter and coconut oil. 
  4. I used muffin cups as a mold for the peanut butter fat bombs but you can be really creative with how you want your fat bombs to look. If you have chocolate molds, you could use them as well to make some truly delectable treats. Combined with some experimentation with the flavors and you can make some delicious fat bombs of your very own.
