The night before you make the cupcakes, infuse the milk with chamomile for the chamomile cream (see recipe that follows). In a medium saucepan on medium heat, bring the milk and chamomile flowers to a gentle simmer for 10 minutes. Then cover with a lid or place plastic wrap on the surface to prevent a skin and refrigerate overnight.
To make the cupcakes, preheat the oven to 350° F. Grease your cupcake cups or pan. Sift the cake flour, salt and baking powder into a medium-size bowl. In a large bowl and using an electric mixer, cream the butter. Gradually add the granulated sugar and beat until the mixture appears light and fluffy. Be sure to scrape down the sides of the bowl.
Add the eggs 1 at a time, beating to incorporate each addition. Then add the vanilla and cardamom.
Alternate adding the milk and flour mixture, incorporating each addition.
Fill each cup in your pan with 2 tablespoons of mixture (or until cups are ¾ full). Bake for 19 to 24 minutes, or until cupcakes appear golden and a tester inserted into the center comes out clean.
Remove the cupcakes from the pan and place them on a rack to finish cooling completely. While cooling, make the chamomile cream filling.
