Vanilla Glaze ingredients:
1/2 C milk
2 C powder sugar
2 tsp vanilla extract

Donut Directions: 
Preheat oven to 400 degrees.
Use a baking spray to prep your doughnut pan (I love this silicone one found on amazon)
Set the pan to the side.
Mix together the flour, baking powder, baking soda, cinnamon, salt and sugar in a large bowl.
Whisk together the whole milk, sour cream , and eggs into a separate bowl.
Whisk in the melted butter, vegetable oil, and vanilla
Gradually whisk in the wet ingredients into the dry ingredients and stir just until combined
Spoon the batter into the doughnut pan.
Bake at 400 degrees for 9 minutes.
Allow doughnuts to cool a few minutes in the pan.
Transfer the donuts to a wire rack to completely cool.

Glaze Directions:

Combine all ingredients into a large mixing bowl and mix until smooth

Pour glaze over doughnuts and let dry for an hour before decorating

Once dry, using the blue cookie icing, pipe a line on the top left corner of the doughnut and fill it in

Pipe 5-7 lines using the red icing onto the doughnuts

Using the white icing, pipe on 10-12 dots on the blue part for the stars in the flag

Let dry for another hour to two hours before enjoying.
