Preheat oven to 350 F.  Line a cookie sheet with parchment paper, then butter edges (OR butter entire cookie sheet).

Melt in a small saucepan over medium to medium-high heat:
1 cup butter

Add, then bring to a boil and let boil for 30 seconds, stirring til very smooth:
1/3 cup cocoa powder
1 cup boiling water

Remove chocolate mixture from heat and set aside.

In a large bowl, mix together: (It's important to mix dry ingredients first in GF cooking to avoid lumps)
3/4 cup brown rice flour
3/4 cup white rice flour
1/4 cup cornstarch OR arrowroot starch
2 Tbsp potato starch
2 Tbsp tapioca starch
1 tsp xanthan gum
1/4 tsp salt
2 cups sugar

Mix chocolate mixture into flour.

In a medium bowl, combine (this will start expanding because of the baking soda):
1/2 cup buttermilk (OR 2 Tbsp apple cider vinegar plus milk to equal 1/2 cup, let rest a few minutes to thicken)
2 eggs, beaten
1 tsp vanilla
1 tsp baking soda

Mix buttermilk/egg mixture into the flour/chocolate mixture above.

Remove from oven and place on a cooling rack.  Immediately begin preparing frosting so you can pour it on while the cake is still warm.
