Pour the eggs, honey, oil and brown sugar into a bowl.
Mix, then add the almond powder, breadcrumbs, cinnamon, salt and baking powder.
Mix well and leave to stand for 10 minutes.
Pour into a square mould lined with greaseproof paper.
Bake at 170°C over static heat (not over revolving heat) for 40 minutes.
Turn out and leave to cool. Then simply cut it into slices.
If you want to make the chantilly, pour all the ingredients except the chantifix into a container or into the bowl of your food processor. Whip at high speed.
When the whipped cream has firmed, add the chantifix and whisk again to obtain a firm texture.
Serve the cake at teatime with whipped cream on hand!
