1Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
In another bowl, melt the butter and let it cool slightly. Add the eggs, vanilla extract, and milk, and whisk until well combined.
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix.
Pour the batter into the prepared cake pan and smooth the top with a spatula.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Allow the cake to cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely.
Once cooled, frost or serve as desired. Enjoy your classic chocolate cake!
