01 - Whisk together flour, baking powder, and salt in a medium bowl. Set aside for later use.
02 - Beat softened butter and granulated sugar in a large mixing bowl until light and fluffy, approximately 2-3 minutes.
03 - Add egg, vanilla extract, and orange zest to the butter mixture. Beat until fully incorporated.
04 - Gradually incorporate flour mixture into wet ingredients, mixing just until smooth dough forms. Avoid overmixing.
05 - Divide dough into two equal portions. Flatten each into a disc, wrap in plastic wrap, and refrigerate for 1 hour.
06 - Process dried cranberries, sugar, orange zest, orange juice, and water in a food processor until finely chopped and spreadable.
07 - Roll one dough portion between parchment sheets into a 9x12-inch rectangle. Spread half the filling evenly, leaving 1/2-inch border on one long edge.
08 - Roll dough tightly from the opposite long edge into a log. Pinch seam to seal. Repeat with remaining dough and filling.
09 - Wrap logs in plastic wrap. Refrigerate for at least 1 hour or freeze for easier slicing.
10 - Preheat oven to 350°F. Line baking sheets with parchment paper.
11 - Cut logs into 1/4-inch rounds. Arrange 2 inches apart on prepared baking sheets.
12 - Bake for 13-15 minutes until edges are lightly golden. Cool on sheets for 5 minutes, then transfer to wire rack.
