Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
In a mixing bowl, cream together the softened butter and granulated sugar until fluffy, about 4-5 minutes.
Add the eggs one at a time, mixing well after each addition to ensure a smooth batter.
Mix in the flour and milk alternately until just combined; fold in the chocolate chips.
Pour the batter evenly into the prepared pans and bake for 25-30 minutes, or until a toothpick comes out clean.
Making the Ganache
Heat the heavy cream until it simmers, then pour it over the chopped chocolate and whisk until smooth.
Once the cakes are completely cool, drizzle the ganache over one layer, letting it drip down the sides.
Notes
For the best flavor, use high-quality chocolate for the ganache.Store leftovers in the refrigerator for up to 5 days. Make sure to cool the cakes completely before applying the ganache to avoid melting.
