Maple Squares with Walnuts (Kopie)

*****
(recipe adapted from Saveur)

8 tbsp. unsalted butter, cubed and chilled, plus more for pan
1 cup plus 2 tbsp. flour, plus more for pan
1/4 cup plus 2/3 cup maple sugar
3/4 cup maple syrup
1 1/4 cup chopped walnuts
1/4 – 1/2 tsp. kosher salt (I did 1/2)
2 large eggs, lightly beaten

Heat oven to 350° F. Butter and flour an 8″ square baking pan; set aside. In a food processor, process butter, 1 cup flour, and 1/4 cup maple sugar until combined; transfer to pan and press evenly into bottom. Bake until lightly browned, about 15 minutes. Whisk remaining flour and maple sugar with maple syrup, walnuts, salt, and eggs in a bowl; pour over baked crust. Bake until filling is golden brown and set, 30–35 minutes. Serve warm, in a bowl, with heavy cream poured over.
