What Is A Fat Bomb?

They’re a combination of healthy fats, nuts or seeds and created to help people who eat a lower carb diet include more healthy fats into their diet.

Typically fat bombs are made in a mini-muffin tin (like this recipe) or rolled into a ball similar to an energy bite.

Fat bombs are typically eaten in the morning, as a snacks to give you energy during the day or at night as a bedtime snack. I love to meal prep these on Sundays and have an easy snack to eat during the week.

Can I Use Another Nut Butter?

You can easily be make them with another nut butter like almond butter or cashew butter. They may even have fewer carbs! Just double check the ingredients for no added sugar.

What Sweetener Should I Use?

I’m a fan of monk fruit when it comes to keto sweeteners that won’t raise ketones or blood sugar. The taste and ingredient quality is the best in my opinion.

I don’t think this recipe needs a sweetener, but if you want it on the sweeter side, you can add this. I’ve also tested this with liquid stevia and it’s a great option. Some processed keto sugars to try are erythritol or xylitol.

Storing Leftovers

Peanut butter fat bombs store well in the refrigerator, but store best in the freezer. Keep them in an airtight container or freezer bag in the fridge for up to 1 week or in the freezer for up to 3 months.
