This is a family recipe that has been passed down for years. Our mom used to make these for us when we were kids. The filling is more like a devil dog filling, not a frosting. Very yummy! This same filling is also great on angel food cake!

Operating without a standard stand mixer requires patience when building the marshmallow-like filling, because the cooked flour-and-milk paste must incorporate completely into the beaten fats and sugar. Hand mixers suffice if run on high speed for a full five minutes, ensuring the gritty sugar crystals dissolve into a smooth emulsion. Standard baking sheets lined with wax paper protect the delicate cocoa cakes from scorching on the bottom, insulating the batter as it spreads and bakes at 350 degrees.
Alternating dry ingredients with liquid milk and vanilla prevents gluten overdevelopment in the batter, keeping the crumb tender rather than tough. Cocoa powder introduces acidity and structure, requiring precise measurement of baking soda to achieve proper leavening without a metallic aftertaste. Dropping the batter by heaping tablespoons onto the pan maintains uniform sizing, ensuring that matching cake halves pair together evenly after cooling on wire racks.
Substituting shortening with additional butter alters the melting point and stability of the filling, resulting in a softer texture that yields quickly at room temperature. Butter contains water that can cause separation if added directly to warm flour paste, whereas shortening maintains a stable emulsion under friction. Maintaining the ratio of fats preserves the structural integrity required to hold the heavy chocolate cakes together without sliding.
Cooling the baked cakes completely before assembly prevents the high-fat filling from melting and squeezing out the sides under pressure. Storing the finished pastries in an airtight container for twenty-four hours softens the exterior crumb further, harmonizing the moisture levels between the cake and the sweet center.
