Preheat oven to fan forced 170ºC. Line a 20cm square cake tin with paper that comes up over the sides for easy removal.
Place butter and chocolate into Thermomix bowl and chop for 3 sec/speed 6.
Scrape down sides of bowl and melt for 3 min/50ºC/speed 1.
Add remaining ingredients except cherries and blend for 6 sec/speed 6. Scrape down sides of bowl and repeat.
Spread batter into prepared tin and arrange cherries into the batter with stalks poking out.
Bake for 25 minutes or until inserted skewer comes out almost clean. (You want moisture for this cake.)
At this point, I was going to drizzle it with chocolate ganache, but truly, it barely made it to the photograph…so up to you. Serve with fresh cream or ice cream, and I am guessing this cake would improve over time…as in; would have been more moist the next day, because that is what coconut does….but I will never know!
