Preheat the Oven: Start by preheating the oven to 180°C (350°F). Prepare your cake pan by greasing and flouring it to prevent sticking.
Mix Dry Ingredients: In a large bowl, combine the flour, cocoa powder, and baking powder. Whisk them together to blend thoroughly.
Whisk Eggs and Sugar: In another bowl, whisk together the eggs and sugar until the mixture becomes light and fluffy.
Combine Wet Ingredients: Stir in the milk and vegetable oil to the egg mixture, mixing until well combined.
Combine the Mixtures: Gradually incorporate the dry ingredients into the wet mixture, stirring until you have a smooth batter.
Pour and Bake: Transfer the cake batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Cool and Frost: Allow the cake to cool completely on a wire rack before applying your desired frosting.
