Cacao nut butter fat bombs are a great way to satisfy a sweet craving. They are packed with healthy fats and a delicious source of energy.
Have you heard of fat bombs?
There was a time when these two little words were feared by anyone trying to keep their weight down. "I"m not having Carbonara sauce, that's a real fat bomb!" "Take away that pork belly/those peanuts/the oil-drenched xyz! The last thing I need is a fat bomb!"
Not the kind of fat bomb I'm talking about! (Even though I love anything drenched in olive oil).
Fat bombs are wonderful little morsels you treat yourself with when you feel like a little energy boost. They are the secret weapon for anyone on a low carb or ketogenic diet.
Like these delicious Cacao nut butter fat bombs!
I have to admit, when I first heard about fat bombs, the idea of eating something by that name did not entice me at all. Why would anyone want to eat a bite of pure fat? Wouldn't that make you, well, fat?
Turns out, the opposite is true. If you cut out the sugar and white carbs and follow a low carb diet, healthy fats such as olive oil, coconut oil, avocado or nuts are a fantastic source of energy for your body. Eating fat AND sugar together is the lethal combination that WILL make you put on weight. Fat alongside fibre and protein? Happy days.
Ingredients
1. Cacao.
I used cacao powder over cocoa. Cacao is made by cold-pressing the cacao beans, while cocoa is produced by roasting them. This minimal processing preserves all the incredible health benefits of cacao. It's rich in nutrients - one of the best plant-based sources of magnesium and iron - and contains 40 times more antioxidants than blueberries. It's also known to be a mood enhancer, regulates insulin levels and lowers blood pressure. The downside is that it is a bit more pricey than cocoa powder, but one pack lasts ages... and it tastes great.
2. Coconut oil.
I know. I have waxed lyrical about coconut oil before. It is one of the richest sources of saturated fats, but cannot be compared to, say, pork fat. The fatty acids in coconut oil are medium chain triglycerides (MCTs), which are metabolised differently by the body - they are converted into immediately available energy rather than being stored long-term. When you buy coconut oil, choose an organic, virgin oil and not the refined stuff.
3. Nut butter.
Whether it's peanut butter, almond butter or walnut butter - nut butters do not only taste great, but are packed with nutrients. Make sure you get a nut butter which contains the only ingredient it truly needs: nuts. No palm oil, no sugar, no salt. In the UK, brands like Biona and Meridian are good options.
Variations
You can play around with the amount of cacao powder - I like an intense chocolate taste, so used 3 tablespoon of cacao for my fat bombs. You could start with 2 tablespoons and take it from there. If you use cinnamon as well, using less cacao will bring out the taste of the cinnamon.
Also entirely optional is the type of nut butter you use. I had almond butter in my cupboard - but if you don't, just use peanut butter, walnut butter or even tahini (in the case of tahini, you might want to decrease the amount as I find it's quite strong in taste).
I don't like my sweets very sweet - therefore, one teaspoon of sweetener is plenty for me. Taste your mix and adjust to your liking!
A quick word about the cream: I have made several versions of these cacao nut butter bombs, using mascarpone (very nice) and cream cheese (not convinced) instead of cream. In another try I used only coconut oil and no cream, which tasted good to me, but did not go down too well with the rest of the family. I guess the cream makes it taste more like dark chocolate you can buy in shops.

I have changed these up a few times. I’ve used a sugar free marmalade and a sugar free raspberry jam and also used your recipe for caramel with a little salt to change up the flavour. Absolutely love them. By far my favourite fat bomb. I freeze them in a silicone ice cube tray and just pop them out as I need them.

How long do organic ingredients last and how should they be stored?
Katrin Nürnberger
It depends on the ingredients. I would always seal packets with nuts and store them in the fridge.
Rachel
How long are these good for in the fridge?
Katrin Nürnberger
Probably around 1 week.
Charlot
Just wondering if you could use olive oil instead of coconut oil? I’m out and really want to make them tonight!
Katrin Nürnberger
As long as you keep them in the freezer it should be possible. Coconut oil is firm at room temperature, whereas olive oil is liquid. However, use a mild olive oil or the taste may be a little strange
Minnie
These were delicious and just what I needed to curb my chocolate cravings. I didn’t add any sweetener as I’m trying to cut out sweetness and they were still very tasty. I put them in a mini muffin tray which worked fine
Lorraine
