Three-dimensional wafer for a homemade Kinder Bueno (part 1, unfinished)

Press thick layers of aluminium foil firmly onto each facet of the plastic chocolate-bar molds to make a heatproof foil mold; patch holes with more foil.

Melt the butter and let it cool.

Add the melted butter, egg whites and a couple of tablespoons of water to the dry ingredients (cake flour, sugar), then vanilla extract and more water until it is like a pancake batter, not thin and not too thick.

Cook the wafer on the stovetop first so it heats immediately and puffs from the baking powder, then before it browns and sets, cut out the stencil on a cutting board, place on the mold and dry in a low oven preheated to 250, to dehydrate without colour.

Heat a grill press on the pan at the lower end of medium; pipe a length of batter and press to cook both sides. Grease the press and pan with butter first.

Cook hotter (medium) and thinner; thinner, softer wafer is more flexible for cutting and shaping.

Oil the inside of the polycarbonate mold with a brush, lay the inner strip in, paint batter along the top rim and bake until dry and crisp; the mold rated to 130 Celsius ('266').
