I've read this and today I've made a coconut cinnamon mug pudding, I've mixed different sweeteners and... wow! No weird flavors, no aftertaste. Thank you for the tip!

If anyone is interested, I call it pudding, because I add a lot of heavy cream and the end result is quite moist.. Coconut, heavy cream, baking powder, egg, cinnamon and 3 different sweeteners to test what Ms Arielle said. I can't give quantities, because I don't measure, but I don't think it makes much difference. Lots of heavy cream, so it's quite wet when it goes to the microwave.
