Wash and dry the pumpkin. Then cut a piece and remove the fibers and seeds. Peel it (place the piece on a cutting board and peel it downwards with a knife) and grate it on a medium grater.

Transfer the grated pumpkin to a small ovenproof dish. Add the egg and oil. Mix thoroughly.

Next, add the flour, cocoa, sweetener, baking powder, and a pinch of salt. Mix and blend until the ingredients are combined (without lumps). Smooth the top of the mixture. Place it in an oven preheated to 180°C for about 20-30 minutes. Remove when the cake rises slightly and cracks on top.

Enjoy warm or cold.
