After 10 minutes, stir in the 1 cup of all-purpose flour

In the bowl of an electric mixer fitted with a paddle attachment, cream
together the butter and sugar for 8 to 10 minutes. With the mixer
on low speed, add the eggs, 1 at a time. When the mixture is smooth, stir in the vanilla and salt. Add the bread flour and mix on low speed until fully incorporated.
Stir in the yeast mixture until thoroughly incorporated. Put the dough into an oiled bowl and allow to proof for 1 to 1 1/2 hours. In a medium bowl, mix together the granulated sugar and the ground cinnamon. Set aside.
Lightly flour a cool work surface and roll the dough out to about 1 1/2-inch thickness. Cut the dough with a round 3-inch cutter and turn them onto a floured baking sheet to rest, about 20 to 30 minutes, before frying.
Heat the oil in a large heavy-bottomed pot to 365 to 370 degrees F. Drop the dough rounds, in batches, into the hot oil and cook until golden brown on 1 side. Using a slotted spoon, turn the dough rounds on the second side and cook until golden brown. Remove them from the oil to paper towels to remove any excess oil. Roll the doughnuts in the cinnamon sugar and arrange on a serving platter. Serve immediately with the Cranberry Jam for dipping.
