Marble Bundt Cake

Method

1. Break the eggs into a large bowl.
2. Add granulated sugar and vanilla extract; beat with an electric mixer for about 5 minutes until light and fluffy.
3. Add vegetable oil and mix.
4. Add milk (or water) and mix.
5. Sift together flour, baking powder, and salt; fold into the batter until smooth.
6. Butter and flour a bundt pan (or use baking spray).
7. Pour about three-quarters of the batter into the pan.
8. Add sifted cocoa powder to the remaining batter and mix well.
9. Pour the cocoa batter on top of the white batter in the pan; use a skewer or knife to create a marbled effect by gently swirling.
10. Bake in a preheated oven at 170°C (340°F) for about 40 minutes.
11. Remove from oven and let cool slightly, then unmold the cake.
12. Prepare a sugar syrup (water and sugar, proportions not specified) and brush it over the cake's surface to glaze.
13. (Optional) Brush with melted chocolate.
