These madeleines echo the introspective and poignant afternoon teas Marianne often shares during her contemplative periods, especially during her time at university.
Preheat the oven to 350°F (175°C).
In a bowl, whisk together eggs and sugar until pale and thick.
Add vanilla extract and melted butter to the egg mixture, combining well.
Sift flour, baking powder, and salt into the wet ingredients and fold gently.
Spoon batter into greased madeleine molds, filling each about 3/4 full.
Bake for 10-12 minutes until golden and springy to the touch.
Cool on a wire rack before serving.
