For dough: In the bowl of a stand mixer fitted with the paddle attachment, place flour, sugar, yeast, and salt. Add sour cream, melted butter, ¼ cup hot water, and eggs; beat at low speed until a soft dough forms. Switch to the dough hook attachment; beat for 8 minutes. Cover bowl with a clean cloth, and let rest for 10 minutes.
For filling: In the work bowl of a food processor, place ground almonds, sugars, egg white, coffee granules, cinnamon, almond extract, and salt; pulse until combined. (Do not overmix, or it will turn into a paste.) Refrigerate until ready to use.
Spray a 13x9-inch baking dish with cooking spray.
On a heavily floured surface, roll dough into an 18x10-inch rectangle. Brush dough with melted butter. Sprinkle with filling, leaving a 1-inch border on long sides of dough. Starting with one long side, tightly roll up dough, jelly-roll style, and press edge to seal. Using a serrated knife, cut into 1½-inch-thick slices. Place cut side down in prepared dish. Cover and let rise in a warm, draft-free place (75°) until doubled in size, about 1 hour.
Preheat oven to 350°. Bake until lightly browned, 25 to 30 minutes.
For coffee glaze: In a small bowl, stir together cream and coffee granules until dissolved. Add confectioners’ sugar, stirring to combine. Drizzle glaze over warm rolls.
