If you love chocolate and peanut butter candy, but you’re following a low carb ketogenic diet, then this easy fat bomb recipe is what you need to kick your cravings to the curb! No baking required. I make these in a $2 ice cube tray from Walmart, and they pop out looking like little candy bars. Fair warning: they start melting the second they leave the freezer, so eat fast. That’s never been a problem at my house.
Just the Facts, Ma’am: 3 ingredients: sugar-free chocolate chips, peanut butter and coconut oil, plus optional walnuts. Melt in the microwave, pour into an ice cube tray and freeze 1 hour. Makes 12 bars at about 150 calories and 1g net carb each. No oven, totally dorm friendly. Keep them in the freezer, because they melt fast!

Want to know who loves fat bombs? Everybody! Especially those of us who are watching our carbs and avoiding extra sugar. But let me back up a little first, in case you’re new here!
Eating a low carb (or ketogenic diet) means getting plenty of healthy fats and lean protein into every meal while avoiding foods with extra sugar and carbohydrates.
It doesn’t mean depriving yourself or feeling guilty if you lose your way now and then. Trust me, I know this because I’ve lost 150 pounds on the keto diet, and if I hadn’t learned how to forgive myself and move on after I went off track or completely off the rails, I would still weigh over 275 pounds and feel like garbage.
How Fat Bombs Helped Me Lose Weight
I’ve always been a dessert person, and that did not change before, during, or after keto. One of the best things I did for myself and my sweet tooth was learning how to make fat bombs.
Fat bombs come in all shapes and sizes and flavors from sweet to savory. If sweet is your jam, you may love these chocolate chip cookie dough fat bombs too.
Fat bombs are easy to put together quickly, and they typically require a few simple ingredients. The only thing special you may need is a silicone mold, but if you don’t have one, its not a deal-breaker.
I make my cookie dough fat bombs on a regular cookie sheet covered with wax paper, and I have used ice cube trays instead of molds on more than one occasion.
The 3 Ingredients You Need
All you need is sugar-free chocolate chips (I use Lily’s), natural peanut butter and coconut oil. That’s it! The coconut oil helps the chocolate melt smoothly and gives these their fudgy texture. Want crunch? Crumble walnuts, almonds or pecans over the top before freezing.

Tips To Make The Best Fat Bombs
- Melt in short bursts. Microwave the chips and coconut oil 30 seconds at a time, stirring in between, so the chocolate doesn’t scorch.
- Use a cookie scoop to fill the ice cube tray. It’s faster and much less messy.
- Press toppings in while the mixture is still warm, or they won’t stick.
- Freeze at least 1 hour. Overnight is even better.
- Store in the freezer, because they melt fast at room temperature!
Chocolate Peanut Butter Fat Bomb FAQ
Can I make these with just 3 ingredients?
Yes! Swap the cocoa powder and stevia for ½ cup sugar-free chocolate chips (like Lily’s). Melt the chips with the coconut oil, then stir in the peanut butter. That’s just 3 ingredients, and it tastes like a peanut butter cup. The chips add a few carbs, so plan on about 2g net carbs each.
Can I make fat bombs in an ice cube tray?
Yes! A regular ice cube tray works great if you don’t have a silicone mold. Fill each cube about ¾ full, freeze for 30 minutes, then pop them out. Silicone trays release the easiest, but a plastic tray works too. Just let it sit on the counter for a minute before you twist it.
What peanut butter is best for keto fat bombs?
Natural peanut butter made with just peanuts and salt. Regular brands like Jif and Skippy have added sugar, which adds carbs. Check the label: if sugar is listed, keep looking.
Why do my fat bombs melt so fast?
Coconut oil and peanut butter soften quickly at room temperature, so these start melting within a few minutes. Freeze them for at least an hour, keep them in the freezer, and eat them straight from it. For photos or parties, chill the plate in the freezer first.
Are these fat bombs dairy-free?
Peanut butter and coconut oil are dairy-free, but chocolate chips vary. For dairy-free fat bombs, choose a chip with no milk in the ingredients, like Lily’s Dark Chocolate Style chips (always check the label), or make the cocoa powder version above.
Can I make these without chocolate chips?
Yes! This was my original recipe, and it’s still a favorite. Melt ½ cup coconut oil and whisk in 2 tablespoons unsweetened cocoa powder until smooth. Stir in ½ cup natural peanut butter and 5–10 drops liquid stevia (to taste), then pour into a silicone mold or ice cube tray and freeze 30 minutes to 1 hour. They’re softer and darker, with about 1.6g net carbs each.

3-Ingredient Chocolate Peanut Butter Fat Bombs
- Total Time: 1 hour 5 min
- Yield: 12 1x
- Diet: Gluten Free
Description
Rich, fudgy keto fat bombs made with just 3 ingredients in the microwave. No baking and no special molds, just an ice cube tray. Perfect for curbing a chocolate craving!
Ingredients
- 1 cup sugar-free chocolate chips (I use Lily’s)
- ½ cup natural peanut butter (no sugar added)
- 2 tablespoons coconut oil
- ¼ cup walnut pieces, crumbled (optional)
Instructions
- Add the chocolate chips and coconut oil to a microwave-safe bowl. Microwave in 30-second bursts, stirring between each, until melted and smooth (about 1 to 1½ minutes total).
- Stir in the peanut butter until completely smooth.
- Scoop or pour the mixture into an ice cube tray, filling each section about ¾ full. A cookie scoop makes this easy and less messy.
- If using walnuts, crumble them over the top and press them in gently.
- Freeze for at least 1 hour, until firm.
- Pop the bars out and serve straight from the freezer.
Notes
Storage: Keep in an airtight container or freezer bag in the freezer for up to 3 months. They soften quickly at room temperature, so serve them straight from the freezer.
Dorm friendly: All you need is a microwave, a bowl and an ice cube tray.
No chocolate chips? Use 2 tablespoons unsweetened cocoa powder plus 5–10 drops liquid stevia in place of the chips, and increase the coconut oil to ½ cup.
Variations: Swap the walnuts for chopped almonds or pecans, or sprinkle a pinch of flaky sea salt on top.
About the carbs: Each bar has about 5g carbs after fiber. Subtracting the sugar alcohols in Lily’s chips brings it to about 1g net carb per bar. If you only count part of the sugar alcohols, plan on 2–3g.
Net carbs: about 1g each
