Preheat the oven to 350 degrees.
Beat the eggs, sugar and vanilla.
Once combined, add the melted coconut oil and mix for 2 minutes.
Add water, flour, cocoa powder, xanthan gum and baking powder.
Once all ingredients are mixed well, pour into a greased (I use coconut oil) cake pan or cupcake liners.
Bake at 350 degrees. An 8 inch cake takes about 30 minutes and cupcakes take about 17-22 minutes.
