Notes
Mix Cornstarch Well: Make sure the cornstarch is completely dissolved in the milk before adding it to the dulce de leche. This helps keep your custard smooth.Watch the Heat: When cooking the custard, keep the heat on medium and stir constantly to prevent burning. If it thickens too fast, lower the heat to keep it silky.Cool the Custard: Let the custard cool a bit before spreading it on the cookies. This makes it easier to spread and keeps the cookies from getting too soft.Layer the Cookies: Lay the cookies evenly, covering the entire mold. This gives your cake structure and a nice balance of flavors.Chill the Cake: Chill the cake for at least 4 hours, or overnight. This lets the flavors blend and softens the cookies to a cake-like texture. For the ganache, refrigerate for an extra 2 hours to set and shine.Slice the Cake: To get neat slices, use a sharp knife warmed in hot water. Clean the knife between cuts to keep the layers looking nice.
