Finely grind approx. 100 g Amarettini in the universal chopper. Whip butter and sugar until white-creamy. Stir in the eggs one after the other. Mix flour and baking powder. Sift the flour mixture over the butter and egg mixture, stir in the ground amarettini, liqueur and orange juice. Line a muffin tray (12 troughs) with paper baking cups.
Spread the mixture in it. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 15-20 minutes. Remove the muffins and let them cool down. Mix mascarpone and lemon curd with a whisk until smooth. Coarsely crumble the remaining Amarettini. Dip the muffins upside down into the mascarpone cream and sprinkle with crumbled amarettini
