Add all-purpose flour to the creamed mixture. Mix on low speed, then increase to medium until well combined and large crumbs appear. Avoid overworking the dough.

Divide dough in two. Wrap one half in plastic wrap and refrigerate. Press remaining dough evenly into the base and sides of the prepared tart pan. Optionally, cover with parchment paper and add pie weights. Bake on a baking sheet for 15 minutes. Allow crust to cool 5–10 minutes after removing from oven.

Spread a thin layer of cranberry jam on cooled crust. Remove reserved dough from refrigerator and crumble half evenly over the jam. Distribute half of the walnut pieces over the top. Repeat with remaining dough and walnuts for a layered effect.
