Preheat oven to 350 F.
In a bowl, whisk eggs and sugar together until combined.
In a separate bowl, gently melt butter and honey in a bain-marie (hot water bath) until hot, avoiding boiling. Add baking soda into this blend, mixing thoroughly until it begins to foam.
Gently stir the egg mixture into the hot honey and butter, then slowly add the flour until the dough is thick and a bit sticky.
Put the dough on a generously floured surface. Continue to add flour as necessary as you roll out the layers. Divide it into 8 equal pieces, and roll each piece to a thickness of 2 mm (1/16 in) on separate, lightly floured parchment papers. Each piece should be about 25 cm (10 in) in diameter.
Bake each layer for about 4 minutes each until golden. Don't over bake.
As you remove each layer, use a pizza cutter and plate or cake mold to trim each layer to 22-cm (9-in) diameter circles. Set trimmings aside for finishing crumbs.
