1. Mix sugar and cinnamon in a bowl. This blend will coat the doughnut fries, giving them a sweet and spicy flavor.2. Take your ready-made dough and roll it out into a 20x30cm (8×12″) rectangle. If there are any seams, make sure to pinch them together.
3. Use a pizza cutter to slice the dough in half lengthwise, then cut across into 1½cm strips to create the ‘fries’.4. Before cooking, dip each strip of dough into melted butter to ensure they crisp up beautifully in the air fryer.
5. Arrange the buttered strips in the air fryer basket or on racks in a single layer. Cook at 380°F for about 5 minutes or until they turn golden brown and crispy.6. While still warm, toss the fries in the cinnamon-sugar mixture to coat them evenly.
