Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt.
Stir in the melted butter, eggs, and vanilla extract until well combined.
Fold in the chocolate chips, then pour the batter into the prepared cake pan.
Bake in the preheated oven for 25 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Cover with ganache.
For the ganache, heat the heavy cream in a saucepan over medium heat until it just begins to simmer. Do not boil. Pour the hot cream over the cup of semi-sweet chocolate chips in a bowl. Let it sit for a minute to soften the chocolate, then stir until smooth and fully combined.
