Place the flour, sugar, baking powder, baking soda and salt in a large bowl and mix together.
Add the milk, vegetable oil, eggs, vanilla extract, food coloring and mix with an electric mixer until combined. Add the melted chocolate and mix well.
Slowly add the boiling water and mix until well combined.
Grease a 9-inch round baking pan. This recipe makes enough to fill 2 baking pans, but we only need one pan-worth for this recipe. You can freeze the extra cake or make 12 cupcakes!
Fill the pan(s) and bake at 350F for 30-35 minutes, until a skewer inserted into the center comes out clean. Cool for 15 minutes in the pan, then turn onto a wire rack and cool completely.
