   Pour 200ml of milk into a mixing bowl. Add 2 eggs and 100g of sugar to the bowl.

2. 2.Whisk Initial Mixture

   Pour 100ml of vegetable oil into the mixture and continue whisking until fully incorporated.

4. 4.Add Cocoa and Cinnamon

   Add 3 tablespoons of cocoa powder and 1 tablespoon of cinnamon to the wet mixture. Whisk thoroughly until the cocoa and cinnamon are completely blended and there are no lumps.

5. 5.Incorporate Flour and Baking Powder

   Gradually add approximately 250g of all-purpose flour along with 10g (one packet) of baking powder to the mixture. Continue mixing until the batter becomes homogeneous and smooth. Add more flour if needed to reach the desired consistency.

   If desired, add chopped walnuts, hazelnuts, or chocolate chips to the batter. Gently fold them in until evenly distributed.
