Prepare Custard
- In a medium pot over medium heat, combine chocolate milk, sugar, cocoa powder, and cornstarch. Whisk until thickened, about 2-3 minutes. Remove from heat and stir in butter, vanilla, salt, and dark chocolate until smooth. Cool, cover, and refrigerate for 2-3 hours.
Bake Cake
- Preheat oven to 350°F (175°C) and grease two 8-inch cake pans. In a bowl, mix room temperature milk and vinegar and let sit for 5 minutes. Add vegetable oil, vanilla, and sugar and mix well.
Mix Dry Ingredients
- Sift together flour, cocoa powder, baking soda, baking powder, and salt into the wet mixture. Fold dry ingredients until just combined.
Add Liquid
- Gradually stir in boiling water or coffee into the batter until smooth and thin.
Bake and Cool
- Pour batter evenly into prepared pans and bake for 25-30 minutes. Cool in pans for 10 minutes on a wire rack.
Assemble Cake
- Trim the tops of the cake layers for even stacking. Place one layer on a plate, spread chocolate custard on top, and add the second layer. Apply a crumb coat of custard, refrigerate for 30 minutes, then finish with a thicker custard layer.
Final Chill
- Chill the frosted cake for another 30 minutes to set the custard before slicing.

Notes
Watch the custard to ensure it's fully set and avoid a runny consistency. Trim carefully for even layers.
