Why are fat bombs good for a keto diet?

Fat bombs are high in healthy fats and very low in carbs, so they help you hit your daily fat macros, curb sugar cravings, and provide quick energy on a ketogenic diet — all without kicking you out of ketosis.

Do keto fat bombs need to stay refrigerated?

Yes. Because they're made with coconut oil and cream cheese, they soften at room temperature and should be stored in the fridge or freezer. They keep up to 2 weeks refrigerated or 3 months frozen.

These no-bake peanut butter fat bombs are the easiest way to stay on track when a sweet craving hits. A creamy peanut butter center under a snappy sugar-free chocolate shell delivers rich, satisfying fat with barely any carbs.

Instructions

Line a 12-cup mini muffin tin with silicone or paper liners, or use a silicone candy mold.

In a medium bowl, beat together the peanut butter, ½ cup coconut oil, cream cheese, powdered sweetener, vanilla, and salt until smooth and creamy.

Divide the mixture evenly among the 12 liners, smoothing the tops. Freeze for at least 20 minutes, until firm.

Melt the sugar-free chocolate chips with 1 tbsp coconut oil in 20-second microwave bursts, stirring between each, until smooth.

Spoon the melted chocolate over each chilled fat bomb to coat the top. Return to the freezer for 10 minutes, until the shell sets.

Store in the fridge or freezer and enjoy chilled — they soften quickly at room temperature.

Tips & notes

Use a natural peanut butter whose only ingredients are peanuts and salt; many commercial brands add sugar that will spike the carb count.

Store in an airtight container in the fridge for up to 2 weeks or in the freezer for up to 3 months.

Swap the peanut butter for almond butter to make these nut-allergy-friendly for peanut-sensitive eaters, or skip the chocolate shell to save a few minutes.
