Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan or line it with parchment paper for easy removal.
In a large mixing bowl, combine sugar, eggs, and vegetable oil. Mix until well combined using a hand mixer or a whisk.
Add in the pumpkin purée and hot coffee, mixing until smooth.
In a separate bowl, whisk together flour, baking soda, baking powder, cinnamon, and salt. Gradually mix the dry ingredients into the wet mixture until just combined.
Pour the batter into your prepared cake pan and smooth the top. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
