A rich super moist chocolate cake with a chocolate buttercream frosting. This is the best cake in the world!
For an exceptionally moist cake, ensure your boiling water is truly hot when adding it to the batter; this helps bloom the cocoa and activate the leavening agents effectively. Do not overmix the batter after adding wet ingredients, as this can develop gluten and lead to a tough cake. When making the frosting, start with softened butter, not melted, for a light and fluffy consistency. If the frosting is too stiff, add a tiny bit more milk; if too thin, add more confectioners' sugar. Cool the cake layers completely before frosting to prevent the buttercream from melting. Leveling the cakes after cooling will provide a professional, even presentation.
