Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until combined.

Add the eggs, milk, vegetable oil, and vanilla to the dry mixture. Mix on medium speed for about 2 minutes until smooth.

Stir in the boiling water until combined.

Pour the batter evenly into the prepared pans and bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean.

Let the cakes cool in the pans for about 10 minutes, then remove them to cool completely on a wire rack.

While the cakes are cooling, beat the softened butter until creamy. Gradually add the powdered sugar and cocoa powder, alternating with milk until well blended. Mix in the vanilla extract.

Place one cake layer on a serving plate. Spread a generous amount of frosting on top, then add the second layer.

Use the remaining frosting to cover the entire cake, smoothing it out with a spatula or knife. Sprinkle chocolate chips on top.

Slice and serve the cake to enjoy a moment of chocolate bliss.
