Put the coconut oil in the mug and microwave for 15-20 seconds until melted.
Add to the mug the coconut flour, almond flour, baking soda and cinnamon and stir. Next add in the orange juice, vanilla extract, egg, honey and finely shredded carrot. Once everything is mixed add the raisins and chopped nuts.
Microwave the mug for 2½ to 3 minutes or until the cake has risen and the top is fully cooked and no longer wet to the touch. Serve topped with coconut cream.
