First put the flour, yeast, salt and sugar in a mixing bowl and mix. Then add the milk and the butter and knead with the dough hook, a good 10 minutes on a medium level. Then knead the raisins under the dough.
Sprinkle cinnamon on the dough and work it roughly into the dough. It should not be uniform, streaks are desired. That gives a nice look later. The dough is perfect if it sticks only lightly.
So let the dough covered for at least 1 hour.
Briefly knead the dough and then form into 8 equal sized balls. Use a cooking spoon to prick a hole in the center of the dough pieces and gently shape into a ring with circular motions. Enlarge the hole with your fingers. If it is too small, that's when baking.
Preheat the oven to 220 ° C.
Bring the water to a boil and insert 2 Bagels each after about 30 seconds turn and then take out. Place on a wire rack and drain.
Put the Bagels on a baking sheet add oat milk on the top and sprinkle with a little sugar.
Bake in the oven for 20 minutes until golden brown.
