A densely chocolate cookie-cake-sandwich filled with fluffy white filling. A perfect treat for school lunches or snacks.
I find it easier to pipe the filling, so feel free to go that route if you prefer.
These make a fairly small cake, perfect for holding in little hands, and especially for school lunches. One of my granddaughters asked me to make them bigger next time; I suggested she have a second one later, and everyone was happy.
