Preheat your oven to 350°F (175°C) and grease a bundt pan with cooking spray or butter.

In a large mixing bowl, combine the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk together until well combined.

Add the eggs, milk, vegetable oil, and vanilla extract. Mix until everything is well incorporated.

Carefully stir in the boiling water until the batter is smooth.

In another bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until it's velvety smooth.

Pour half of the chocolate batter into the prepared bundt pan, followed by dollops of the cream cheese mixture. Top with the remaining chocolate batter.

Using a knife or a skewer, gently swirl the cream cheese mixture into the chocolate batter.

Place your bundt pan in the oven and bake for 50-60 minutes, or until a toothpick comes out clean from the center.

Once baked, let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Once cooled, pour over your chocolate ganache before slicing and serving.
