Peel and core 4 small apples and cut into thin wedges. Drizzle with the juice of 2 lemons to stop them browning.
In a bowl, whisk 150 g instant flour with 2 pinches saffron baking powder, 2 pinches salt, and 2 packets of vanilla sugar. Beat in 4 medium eggs and 200 ml milk until the batter is smooth.
Heat a non-stick pan over medium heat. Sprinkle in 1 tsp brown sugar, arrange a quarter of the apple wedges over it, and let the sugar caramelize for 2 min, until amber.
Scatter 1 tbsp butter flakes over the apples, then pour in a quarter of the batter to cover. Cover with a lid and cook over medium-low heat for 4–5 min, until the top is set and the underside is golden. Slide onto a plate and keep warm in a low oven.
Repeat with the remaining sugar, apples, butter, and batter to make 3 more pancakes.
Just before serving, scatter 40 g fat-free roasted flaked almonds over the pancakes.
