Combine the yeast mixture, evaporated milk, oil, sugar, egg, vanilla, baking powder, salt, and 2 cups flour in a stand mixer with a paddle attachment at medium speed until smooth.
Replace the paddle attachment with a dough hook attachment of an electric mixer and add enough remaining flour to make a soft dough that is still a little sticky.
Fry 2-3 beignets at a time in oil that is 375 degrees until golden brown. Use tongs to remove the Mickey Beignets from the hot oil and place them on a paper towel for 1-2 Minutes.
Add 1/2 cup powdered sugar to a paper bag and add one beignet at a time. Close the bag and shake until the beignet is covered with powdered sugar. Tap below for the full recipe!
