Instructions

Working time approx. 15 minutes; Total time approx. 15 minutes

Preheat the oven to 180°C (160°C fan-assisted oven). Grease a muffin tin or line it with paper baking cups. Crumble the speculatius biscuits and mix thoroughly with the flour, almonds, spices, baking powder, and baking soda. Lightly whisk the eggs in a large bowl. Stir in the sugar, butter, yogurt, and coffee thoroughly. Add the flour mixture and mix until the dry ingredients are moistened. Pour the batter into the baking tin. Bake in the oven (middle rack) for about 20-25 minutes. Let the muffins rest in the baking tin for 5 minutes, then let them cool. For the glaze, lightly whisk an egg white. Mix about a tablespoon of it with the cinnamon and powdered sugar until you get a spreadable glaze. Brush on the mixture and decorate with speculatius biscuits.
