Preheat the oven to 180 ° C top / bottom heat (convection: 160 ° C). Line a baking sheet with parchment paper.
First crumble the marzipan mixture with your fingers in a mixing bowl and mix with the other dough ingredients to form a smooth dough.
Place 12 piles of the dough on the prepared baking sheet with 2 tablespoons and bake until golden yellow for about 15 minutes. Carefully place on a wire rack and let cool down.
For the icing, heat the milk with the marzipan mixture in a small saucepan, stir until smooth and stir in the powdered sugar. Brush the flat side of the cooled Americans with the warm icing and sprinkle with chocolate sprinkles.
Alternative: For a simple glaze, stir approx. 150 g of powdered sugar with 3 - 4 tablespoons of lemon juice in a cup and coat the Americans with it.
