   Beat with a hand mixer or whisk until smooth and creamy.

Keeping It Fresh

• Refrigerator: Store in an airtight container for up to 2 weeks.
• Freezer: Freeze for up to 3 months.

  Let sit at room temp for 3–5 minutes before eating.

• Prevent odors: Use a tight-sealing container so they don’t absorb fridge smells.
• Keep them cold: They soften quickly at room temperature due to the coconut oil and butter.

Benefits of This Recipe

• Keto-friendly: Very low in net carbs with plenty of healthy fats to support ketosis.
• Satisfying snack: A small piece fights cravings and helps you avoid sugary treats.
• Quick energy: Fats provide steady energy without a sugar spike.
• Customizable macros: Adjust sweetener, add cocoa, or swap nut butters to fit your goals.

What Not to Do

• Don’t use sweetened peanut butter: Added sugar can push carbs too high.
• Don’t skip the powdered sweetener: Granulated sweetener can be gritty. Use powdered for a smooth texture.
• Don’t overheat the fats: Excess heat can separate the mixture and dull flavor. Melt gently if needed.
• Don’t leave them out: They soften fast.

  Keep them chilled until serving.

Alternatives

• Nut butter swap: Try almond butter, cashew butter (higher carbs), or sunflower seed butter for nut-free.
• Dairy-free: Replace butter with more coconut oil or palm shortening. Add a pinch of extra salt for balance.
• Flavor twists: Add cinnamon, espresso powder, or a few drops of maple or banana extract (sugar-free).
• Crunch factor: Stir in crushed roasted peanuts, coconut flakes (unsweetened), or cacao nibs.
• Chocolate shell: Dip set bombs in melted sugar-free chocolate and chill again for a glossy coating.

FAQ

How many carbs are in each fat bomb?

Exact macros vary by brand and portion size, but a typical mini-muffin-sized piece has about 1–2g net carbs. Check your labels and recalculate if you add mix-ins.

Can I make these without coconut oil?

Yes.

Replace coconut oil with more butter for a richer, slightly firmer texture, or use ghee for a hint of nuttiness. The flavor will change slightly.

Why is my mixture grainy?

You likely used granulated sweetener or a peanut butter with gritty texture. Use powdered sweetener and a smooth, natural peanut butter.

Mixing a little longer also helps.

Do I need a silicone mold?

It helps with easy release, but not required. You can spoon mounds onto a parchment-lined baking sheet, chill, and store once firm.

Can I reduce the sweetener?

Absolutely. Start with less and add to taste.

Many people prefer these lightly sweet since peanut butter is naturally rich.

Are these safe for kids?

Yes, if there are no nut allergies and they tolerate sugar alcohols well. Keep portions small and monitor for sensitivity to sweeteners like erythritol.

In Conclusion

Keto Peanut Butter Fat Bombs are a simple, reliable way to satisfy cravings while staying low-carb. With just a few ingredients and no baking, you get a creamy, customizable treat ready whenever you need it.

Keep them chilled, tweak the flavor to your liking, and enjoy a smart snack that actually supports your goals.
