Sieve the flour and baking powder onto a work surface. Press a depression in the middle. Add the egg, egg yolk and cream. Spread cold fat in flakes as well as 70 g sugar, salt and 2 teaspoons cinnamon on the edge of the flour.
Chop through all ingredients with a large knife. Then knead quickly with your hands to a smooth shortcrust pastry. Wrap in cling film and chill for about 30 minutes. Then form the dough into 15 cm long and approximately pencil-thick rolls.
Place the pretzels on a baking tray lined with baking paper. Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 12-15 minutes. Mix the remaining sugar with cinnamon in a deep plate.
Roll the still warm pretzels in it. Makes about 60 pieces.
