Preheat the oven to 180 degrees.
Prepare the coffee and let it dissolve in the soluble one.
Grease and lightly flour a 20/22 cm diameter tin.
Sift flour, baking powder and salt twice into a bowl.
In a bowl or in the planetary mixer, whip the eggs with the sugar until you get a nice frothy mixture, add the pumpkin and continue to whisk. Add the oil and the coffee. Stir in the flours and work the mixture just enough to mix well.
Pour everything into the pan and level.
Cook for 35/40 minutes or until the appetizer comes out completely dry.
Let it cool in the tin for a few minutes before transferring it to a wire rack to cool completely.
