In a large bowl, whisk together the flour, sugar, baking powder, cinnamon, and salt.
2 cups all-purpose flour, 3 tablespoons powdered sugar, 1 teaspoon baking powder, ½ teaspoon ground cinnamon, ¼ teaspoon kosher salt
In a medium bowl, whisk the milk, eggs and vanilla until combined.
1¼ cups whole milk, 2 large eggs, ½ teaspoon pure vanilla extract
Pour the wet ingredients into the dry and whisk until mostly smooth, a few small lumps are okay.
Transfer the batter to a piping bag with a large round tip, a funnel, or a liquid measuring cup.
Pour the batter into the hot oil, swirling and looping to make the classic funnel cake shape.
Let the batter cook until golden on the underside, about 90 seconds. Gently flip with tongs and cook the second side for another 60-90 seconds.
Remove the funnel cake and set it on the wire rack. Repeat with the remaining batter. Let the funnel cakes cool slightly, dust with powdered sugar, and enjoy.
