Heat the oven to 200 C (393F).
Grease a baking tray with butter or oil.
In a bowl, add wholegrain flour, white flour, baking powder, baking soda nd salt.
Whisk until well incorporated.
In another bowl, mix the yogurt, eggs, and maple syrup. Incorporate the liquid mixture into the flour mixture with the help of a whisk.
Add the butter and mix again. Don't overmix, it's ok if you get a lumpy dough.
In a small bowl, mix cream cheese with sugar.
Pour the dough into the baking tray greased in advance, on one quarter of the surface, spread the banana slices, on another quarter, the chocolate drops, on another raspberry and on the remaining quarter, add the cream cheese, a teaspoon at a time and spread with the tip of a knife or a toothpick. Then sprinkle with blueberries.
Put it in the oven and cook for 15 minutes or until it turns golden-brown on the surface. Drizzle with maple syrup, cut into squares and serve.
