Add neutral frying oil to a large saucepan over medium high heat so it’s 4-5″ deep. Heat up until 350F, or the oil is glistening.
In a large bowl, combine the flour, sugar, baking powder, cinnamon, and salt. Mix well.
Add the sourdough discard, melted butter, and hot water. Mix until a thick batter.
Add the sliced peaches and toss until well coated.
Working in small batches, fry the peaches for 2-3 minutes, until deeply golden.
Use a slotted spoon to transfer to a paper towel lined plate.
To make the glaze, combine the powdered sugar, cinnamon, and maple syrup. Mix in 1 teaspoon milk at a time until a thick glaze. Drizzle over each the peach fritter bites. Enjoy warm!
