GRAHAM-FLOUR AND JAM PASTRY SQUARES

Steps:

• Pulse flours and salt in a food processor to combine. Add butter and cream cheese and pulse until small pieces remain. Add ice water and pulse until dough just starts to clump together.
• Turn out dough (it will be crumbly) onto a clean work surface and divide in half. Wrap each in a piece of plastic wrap and press to form a flat rectangle. Refrigerate dough until firm, at least 20 minutes and up to 1 day.
• Preheat oven to 375 degrees. Roll out each rectangle on a lightly floured piece of parchment to a 10-by-14 1/2-inch rectangle. Transfer one rectangle (with parchment) to a baking sheet. Spread jam on top, leaving a 1-inch border all around. Roll up remaining rectangle on rolling pin, then unroll on top of first rectangle. Press edges together, then use a crimped pastry wheel to trim all around. Brush beaten egg over top, then use a paring knife to cut a few vents in top crust. Refrigerate 30 minutes.
• Bake until golden and jam is bubbling up through vents, about 35 minutes. Let cool completely on baking sheet on a wire rack. Pastry can be stored, covered in plastic, up to 1 day before glazing and cutting.
• Whisk together confectioners' sugar and 1 tablespoon milk in a small bowl; if mixture is too thick to pour, add more milk, a drop at a time. Drizzle icing over top of pastry, then let set at least 10 minutes before cutting into 12 squares, 3 across short side, 4 down long side.
