How to Make It
Pour oil to a depth of 2 inches in a large saucepan, deep fryer, or Dutch oven. Heat over medium-high to 350°F.
Whisk together flour, 2 tablespoons sugar, baking powder, salt, and 1/2 teaspoon green chile powder in a large bowl; set aside. Whisk together milk, eggs, and melted butter in a medium bowl until combined.
Add milk mixture to flour mixture, and stir until just combined. (It’s OK if the batter is a little lumpy.) Fold in apple.
Once oil is hot, use a tablespoon to lower dollops of batter into hot oil. (Be careful here, as you don’t want the oil to splatter.) Use a butter knife or small heatproof spatula to coax the batter from the tablespoon into the oil. Fry in small batches, no more than 5 at a time, to help keep the temperature of the oil steady. Cook, until golden brown, about 2 minutes per side.
Remove fritters from oil, and place on a paper towel–lined plate. Stir together remaining 1/2 cup sugar and remaining 1 teaspoon green chile powder in a small bowl. Toss warm fritters in sugar mixture. Serve fritters warm.
