Instructions
- Preheat oven to 175°C (350°F) and line 2 (or 3) round cake pans with parchment.

- Add eggs, milk, oil, and vanilla; beat until smooth.
- Add boiling water/coffee to the batter, which will be thin.
- Pour batter into pans and bake for 28–34 minutes for 8-inch pans. Cool completely.
- Heat heavy cream until steaming, pour over chocolate chips, let sit for 2 minutes, then whisk smooth. Add butter and a pinch of salt, let thicken for 20–30 minutes.
- Beat butter and sugars until fluffy, then add milk and vanilla. Mix in heat-treated flour and salt, fold in mini chocolate chips, and chill for 10 minutes.
- Beat butter for 3 minutes, gradually add powdered sugar, then add cream, vanilla, and salt. Beat until light and fluffy.
- Assemble the cake by placing the first chocolate cake layer, spreading a thick layer of chocolate fudge, adding the next cake layer, spreading the cookie dough cream, and adding the final cake layer.
- Apply a thin crumb coat of buttercream, chill for 20 minutes, then add a smooth final coat of vanilla buttercream and decorate the top.
- Chill the whole cake for 1 hour before slicing for clean layers. Store refrigerated up to 5 days.
