Preheat your oven to 350°F (175°C). Grease two round cake pans with butter or cooking spray and line the bottoms with parchment paper.

In a large mixing bowl, whisk together the dry ingredients: flour, cocoa powder, sugar, baking powder, baking soda, and salt.

In a separate bowl, whisk together the wet ingredients: eggs, milk, vegetable oil, and vanilla extract until smooth.

Pour the wet ingredients into the dry ingredients and gently fold them together until just combined.

Divide the batter evenly between the prepared cake pans and bake for 30 to 35 minutes until a toothpick comes out with few moist crumbs.

For the ganache, heat heavy cream until it simmers, then stir in the chocolate chips until smooth and glossy.

Allow cakes to cool for 10 minutes in the pans, then transfer to a wire rack to cool completely before assembling with ganache.
