Preheat the oven to 180 degrees.
Grease and lightly flour a 24 cm diameter mold.
Sift the flour, baking powder and baking soda into a bowl. Add the cinnamon and salt.
In a bowl or mixer, mix the eggs, pumpkin, oil, sugar and vanilla. Stir in the flours and work the mixture just enough to mix well.
Pour everything into the pan and level.
Cook for 40/45 minutes or until the appetizer comes out completely dry.
Let it cool in the mold for a few minutes before transferring it to a wire rack to cool completely.
