Combine the granulated sugar, butter, milk, honey, egg, and salt in a large saucepan. Stir over low heat until melted and smooth, keeping it below a boil. Stir in the baking soda until the mixture foams, then remove from the heat.

Stir about half of the flour into the warm mixture. Dust the counter with the remaining flour, turn the mixture out, and knead until a smooth dough forms. Divide into 4 equal pieces.

Heat the oven to 350°F (180°C). Roll each dough piece very thin into a rectangle, about 9 by 13 inches, and transfer to parchment-lined baking sheets. Bake each sheet for 8-10 minutes until lightly golden at the edges, then cool completely.

Whisk the milk, granulated sugar, cornstarch, and vanilla in a saucepan. Cook over medium heat, whisking constantly, until thick and bubbling. Transfer to a bowl, cover the surface, and cool to room temperature.

Beat the softened butter and powdered sugar until pale and smooth. Add the cooled pudding base a few spoonfuls at a time, beating well after each addition until the cream is silky.

Layer one honey sheet with half the cream, add a second sheet, spread with jam, add a third sheet, spread with the remaining cream, and top with the final sheet. Cover with parchment, place a light board on top, and refrigerate overnight.

Bring the heavy cream just to a simmer and pour it over the chopped chocolate. Rest for 2 minutes, stir until glossy, then spread over the chilled cake. Chill until set, trim the edges, and cut into 28 small petit fours.
