Preheat the oven to 300 F / 150 C.
In a small saucepan, melt the butter.
Once melted, stir in the cocoa powder until no lumps are visible and set aside.
In a large bowl, mix together all remaining dry ingredients.
In a medium bowl, mix together all liquid ingredients, including the butter mixture. (Ensure it is no longer hot!)
Add 1/3 of the liquid mixture to the dry ingredients and mix, repeat until all ingredients are fully combined.
Bake at 300 F / 150 C for 40 minutes.
Once cool, frost and enjoy!
