To prepare a sweet and spicy chocolate cake recipe, first you need to prepare the ingredients for the cake. First, you'll need the following ingredients: 12 cup sugar, 1 cup cocoa powder, 2 tablespoons butter, and 1 teaspoon vanilla extract. You can find these ingredients at your local grocery store or online. Then, pour the wet ingredients into the dry ingredients and mix them together until they're well combined. Next, add the chocolate chips and beat them with an electric mixer on medium-high speed until the chips are completely melted. Pour the batter into an oiled cake pan and bake it in the oven for 35 to 40 minutes, or until it's just set. Allow it to cool for 10 minutes before cutting it into squares and serving it.
