Moist Orange Candied Peel Cake with Crunchy Streusel

In a bowl, combine the eggs, sugar, vanilla sugar, and a pinch of salt, then mix thoroughly.

Add the vegetable oil, yogurt, and milk, and mix again until smooth.

Sift the flour with the baking powder and fold it into the wet mixture.

Finally, fold in the candied orange peel.

Grease a baking pan with butter, dust with flour, and pour in the batter.

For the topping, combine the flour, sugar, and butter in a separate bowl, rub into crumbs, and sprinkle over the batter.

Place the pan in a preheated oven at 180°C (350°F) and bake for about 40–45 minutes until golden brown and a skewer inserted comes out clean.
