Follow these easy steps to create a delicious Chocolate Espresso Cake:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.

2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.

3. Combine Wet Ingredients: In another bowl, whisk together the brewed espresso, vegetable oil, eggs, and vanilla extract until well combined.

4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until smooth. Be careful not to overmix.

5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips if you desire some extra chocolate goodness in your cake.

6. Divide Batter: Pour the batter evenly into the two prepared cake pans.

7. Bake: Place in the preheated oven and bake for 30-35 minutes. A toothpick inserted in the center should come out clean.

8. Cool: Remove from the oven and let the cakes cool in their pans for 15-20 minutes. Then, gently transfer them to wire racks to cool completely.

9. Assemble the Cake: Once completely cooled, place one layer on a serving platter. Top generously with your favorite chocolate frosting.

10. Finish the Cake: Add the second layer on top and frost the top and sides of the cake. For an added touch, dust with cocoa powder or powdered sugar before serving.

Now, your incredible Chocolate Espresso Cake is ready to be enjoyed!
