Preheat the oven to 180°C (350°F).

In a deep bowl, mix the semolina, vanilla extract, and baking powder.

Add the sugar and yogurt to the semolina mixture. Mix well until the sugar dissolves.

Add the butter and shredded coconut, and mix thoroughly.

Pour the Harissa mixture into a baking pan and let it rest for a few minutes.

Place the pan in the preheated oven for 30 minutes, or until the top is golden brown.

Drizzle the maple syrup evenly over the Harissa according to your taste. Cut into pieces and serve warm or cold.
