In a large bowl, combine all the dry ingredients.
In a large bowl or measuring cup, measure all the wet ingredients. If using instant espresso ;powder, whisk it into the liquids.
Add the wet ingredients to dry ingredients; mix until combined, but don't over mix.
Pour the batter into the prepared baking pan, bake for 30-35 minutes or until a cake tester/ toothpick inserted into the center comes out clean.
Let cool in the pan for 10 minutes before inverting onto a wire rack to cool completely. Frost as desired.
