Put an oven rack in the center of the oven. Preheat the oven to 350 degrees F. Butter and flour a 9-inch round cake pan.
In a medium bowl, whisk together the flour, cornmeal, baking powder, salt, and orange zest. Measure 3 tablespoons of the flour mixture into a small bowl. Add the chopped cranberries and toss until coated. Using a stand mixer fitted with a paddle attachment, beat the butter and sugar on medium speed until light and fluffy, about 2 minutes. Beat in the vanilla extract. Add the egg yolks and whole eggs, 1 at a time. Gradually add the flour mixture and mix until just incorporated. Using a spatula, gently fold in the cranberries.
Pour the batter into the prepared cake pan and smooth the surface with a spatula. Bake until the cake is golden brown, and a cake tester inserted into the center of the cake comes out clean, about 40 minutes. Cool for 20 minutes. Remove the cake from the pan and transfer to a wire rack to cool completely. Cut the cake into wedges, arrange on a serving platter and serve with the Caramel Walnut Sauce. (The cake can be made 1 day ahead. Store airtight in a plastic container.)
