Make the crust:
Line a straight-sided 13x9-inch metal baking pan with foil, letting the ends create an overhanging edge for easy removal. In a medium bowl, stir together the butter, 3/4 cup of the sugar, and the salt. Whisk in the egg yolks. Stir in the flour to make a stiff dough. Transfer about 2 cups of the dough to the prepared pan, and press the mixture evenly into the bottom. Prick the dough all over with a fork. Refrigerate the pan for 30 minutes (or freeze for 5 to 7 minutes), until the dough is firm.
Meanwhile, position a rack near the center of the oven and another near the top. Heat the oven to 325°F.
Bake the dough until the crust begins to set but does not brown at all on the edges (the center will not be firm yet), about 20 minutes. While the crust bakes, prepare the streusel and the topping.
Make the streusel:
With your fingers, combine the remaining 1/4 cup granulated sugar with the reserved dough until crumbly. The mixture should hold together when pressed, but readily break into smaller pieces.
Make the cranberry topping:
In a medium saucepan, bring the cranberries, sugar, and 1/4 cup water to a boil over high heat. Reduce the heat to medium high and continue to boil until the liquid is reduced to a thick syrup, 5 to 8 minutes. Remove the pan from the heat and let the mixture cool 5 to 10 minutes—the syrup will continue to thicken as the mixture cools.
Spread the cranberry mixture evenly over the hot crust. Scatter the streusel over the cranberries (don’t crumble the streusel too much or the texture will be sandy). Increase the oven temperature to 350°F and bake the bars near the top of the oven until the streusel is golden and set, about 25 minutes. (Baking these bars at the top of the oven helps the streusel brown faster without overbrowning the crust.)
Place the pan on a metal rack to cool until the crust is completely firm, at least 1 hour. (For faster cooling, put the bars in the fridge once the pan is no longer piping hot, or even outside in winter.)
When the bottom of the pan is cool, carefully lift the bars from the pan using the foil sides and transfer them to a cutting board. Separate the foil from the bars by sliding a spatula between them. Cut the bars into 1-3/4-inch squares.
Make Ahead Tips
The bars will keep at room temperature for one week.
