Begin by slicing your fresh pineapple into 1/2-inch thick rings, ensuring a steady surface for even cooking. Set aside on a plate.

In a mixing bowl, whisk together flour, sugar, baking powder, salt, and ground cinnamon. Create a well, add egg and milk, stirring until smooth.

In a fryer or pot, pour vegetable oil and heat to 375°F (190°C). Use a thermometer for accuracy.

Dip each pineapple ring into the batter, ensuring full coverage. Allow excess batter to drip off before frying.

Carefully place coated rings in hot oil, frying in batches. Cook for about 2 minutes on each side until golden brown.

Remove fritters from oil and drain on paper towels. Dust with cinnamon and sugar while warm.

Plate the fritters warm and serve with coconut ice cream if desired.
