Wash, peel, and dice fresh peaches into bite-sized pieces or use well-drained canned peaches, patting dry.

In a large bowl, whisk together flour, sugar, baking powder, salt, and cinnamon until combined.

In a separate bowl, beat together eggs, milk, vanilla, and melted butter until smooth.

Fold wet mixture into dry mixture; be careful not to overmix. Gently stir in diced peaches.

Heat vegetable oil in a skillet over medium heat until it reaches 350°F.

Drop spoonfuls of batter into the hot oil, frying in small batches for 3-4 minutes on each side.

Use a slotted spoon to transfer the fritters to a paper towel-lined plate to drain excess oil.

Dust warm fritters with powdered sugar or drizzle with glaze, if desired.
