This one-bowl chocolate coffee cake is rich, moist, and easy to make, perfect for any occasion.
Preheat your oven to 350°F (175°C).
Preheating ensures even baking from the start.
Grease a 13x9-inch baking dish thoroughly.
Use butter or non-stick spray for easy cake removal.
In a large mixing bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, salt, and cinnamon.
Sifting the dry ingredients helps avoid lumps.
Add the eggs, brewed coffee, vanilla extract, milk, vinegar, and vegetable oil to the dry ingredients. Mix until smooth using an electric mixer.
Mix on medium speed to avoid overmixing, which can make the cake dense.
Pour the batter into the prepared baking dish.
Tap the dish gently on the counter to release air bubbles.
Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Avoid opening the oven door frequently to maintain a consistent temperature.
Let the cake cool completely in the dish before frosting or serving.
Cooling prevents the frosting from melting and ensures clean slices.
Serve the cake as is or with your favorite frosting. Enjoy!
Pair with a scoop of ice cream for an indulgent treat.
