Brush 1 tortilla with melted butter. Set a second tortilla on top and brush it with butter. Repeat until you've buttered and stacked all 5 tortillas.
5 flour tortillas, 3 tablespoons unsalted butter
Use a pizza cutter to cut the stack in half, then into quarters, then into eighths.
Arrange the wedges buttered side up on the baking sheet so they don't touch. Sprinkle with the cinnamon sugar.
Bake for 8 to 10 minutes, rotating the pan halfway through, until golden brown and firm to the touch. Watch closely for the last 2 minutes so they don't burn. Cool completely.
For the Apple Pie Party Dip:
Peel and core the apples, then dice them into bite or smaller-sized pieces. Combine apples, lemon juice, brown sugar, preserves, and cinnamon in a bowl.
