Preheat your oven to 175°C (350°F). Grease the bundt pan well with butter and dust with flour. This step prevents sticking and helps the cake release easily after baking.

In a large bowl, add flour, cocoa powder, sugar, baking powder, baking soda and salt. Mix well using a whisk. This ensures even distribution of all dry ingredients.

Add eggs, milk, oil and vanilla extract into the dry mixture. Mix slowly using a mixer or whisk. Blend until smooth and creamy without overmixing the batter.

Carefully pour hot coffee or hot water into the batter. Mix slowly until combined. The batter will be thin. This step enhances chocolate flavor and keeps cake moist.

Fold in chocolate chips if using. This adds extra richness and texture to the cake. Mix gently to spread them evenly in the batter.

Pour the batter into the prepared bundt pan. Tap the pan lightly on the counter. This removes air bubbles and helps the cake bake evenly.

Place the pan in the oven and bake for 40–45 minutes. Insert a toothpick in the center. If it comes out clean, the cake is ready.

Let the cake cool in the pan for 10 minutes. Then transfer to a cooling rack. Let it cool completely before slicing. Serve plain or with glaze.
