Hello!  Are you into baking cakes?  
I love to eat them, but I've never baked them before. It is difficult?
It is not that difficult.  You just have to use the correct ingredients like flour, eggs etc. 
What do you do with all of the ingredients? Do you throw them in a bowl?
You throw them in a bowl in the correct proportions, then put them in an oven, sort of like you would with a barbecue in a masonry oven. 
That doesn't sound too difficult. How long does it take to bake a cake?
It depends on the method you are using. You have to use prolonged dry heat in an oven, but it could be made even on hot ashes or stones.
