Beat soft butter lightly with a whisk, add eggs, beat.
Dissolve yeast in milk, pour in the egg mixture, add flour with baking powder. Knead a soft dough that does not stick to your hands, put it in a bag and put it in the refrigerator for two hours.
Preheat the oven to 180 degrees. Divide the dough into 3 parts. Roll out each part into a circle. Cut into segments, put jam on the edge and wrap each segment with a bagel, not tight! Place on a parchment-lined baking sheet and bake for 20 minutes until golden brown. Happy tea!
