Cinnamon Roll Donuts

I was excited to use my donut pan again for a new recipe.  There are so many donut recipes I want to try but just haven't gotten to yet.  We had another unexpected snow day so donuts were just what we needed on a cold morning.  This recipe is slightly adapted from Buns In My Oven.


For the donuts:
1 cup flour
1/4 cup plus 2 tbsp white sugar
1 tsp baking powder
1/2 tsp ground cinnamon
1/2 teaspoon salt
1/4 cup plus 2 tbsp buttermilk
1 egg
1/2 tsp vanilla
1 1/2 tsp vegetable oil

Cinnamon topping:
2 tbsp butter
2 tsp cinnamon
5 tbsp brown sugar
1 tsp milk
1 tsp cornstarch
1 tsp vanilla

For the glaze:
1/4 cup powdered sugar
1 tbsp plus 2 tsp milk

Heat oven to 325.  Grease donut pan.  In a small saucepan melt the butter then stir in the cinnamon, brown sugar and cornstarch.  Bring the mixture to a boil then remove from heat and stir in vanilla.  Pour evenly into the bottom of each donut well.  In a mixing bowl combine the flour, sugar, baking powder, cinnamon and salt.  In a small bowl whisk together the buttermilk, egg, vanilla and vegetable oil.  Pour the buttermilk mixture into the flour mixture and stir until combined.  Carefully spoon the batter into the donut pan.  Bake for 10 minutes. Remove from oven and let cool for 2 minutes before removing the donuts.  Let the donuts cool for 5 more minutes before making the glaze.  In a small bowl whisk the milk into the powdered sugar. Pour into a small ziplock bag and cut the tip off and drizzle across each donut.  Serve right away or let cool longer.
