Melt chocolate and coconut oil. You can do this in a water bath, a coated pot on the stove (gentle heat!) or in the microwave (4x 30 second bursts).
Crush your walnuts - I used a food processor - until you have small pieces. Keep a few larger ones to decorate the fat bombs. Dry-roast the walnuts in a pan on the stovetop over low heat until browned (optional).
Add the crushed walnuts, cinnamon and stevia to the melted chocolate mixture.
Pour into silicone moulds or ice cube tray and freeze for around 5 minutes until the tops are just set.
Remove the fat bombs from freezer and press the larger walnut pieces on top.
Return to the freezer for another 20 minutes until the fat bombs have set.

Notes
My mix made 30 Keto fat bombs, which weighed between 5 and 8 grams because I used 2 different-sized moulds. The nutrition is calculated for an average fat bomb weighing 6.6g.If you do not have moulds, you could also line a small tray with baking paper and pour the fat bomb mix into it. After it has firmed up you can either cut or break it into small pieces.Chocolate walnut fat bombs are best kept in the fridge or in the freezer. They stay firm at room temperature but do melt in your hand when you pick them up. I used caramel-flavoured stevia. I imagine a vanilla-flavoured one would be good in this recipe, too.
