Preheat the oven to 190 ° C (top / bottom heat). Grease a 21 x 25 cm baking pan (or a corresponding springform pan) and sprinkle with a little sugar.
Beat the eggs with the sugar until frothy. Then add the flour, baking powder, butter and the pulp of the vanilla pod.
Peel the apples, remove the core and cut into small pieces. Add the apple pieces, lemon peel, lavender blossoms and amaretto to the batter and stir in.
Pour everything into the prepared dish and bake in the oven for about 30 minutes until golden. The cake tastes lukewarm but also very good cold.
