Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan to prevent sticking.
Mix the Wet Ingredients
In a mixing bowl, combine the ricotta cheese, sugar, milk, vegetable oil (or melted butter), eggs, and vanilla extract. Whisk until the mixture is smooth and creamy.
Combine the Dry Ingredients
In another bowl, whisk together the flour, cocoa powder, baking powder, and salt until well combined.
Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture. Stir gently until just combined; be careful not to overmix. If desired, fold in the chocolate chips for an extra chocolatey flavor.
Bake the Cake
Pour the batter into the prepared cake pan and smooth the top. Bake in the preheated oven for 35-40 minutes or until a toothpick inserted into the center comes out clean.
Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
Serve and Enjoy
Before serving, dust the top of the cake with powdered sugar. You can also add fresh berries for a pop of color and flavor. Enjoy this delightful dessert!
