In the bowl of a stand mixer fitted with the paddle attachment, combine 2 cups (250g) flour, sugar, Platinum Yeast, and salt.
In a medium saucepan, heat 1/2 cup (120g) water, milk, butter, and vanilla over medium heat until an instant-read thermometer registers 120°F (49°C) to 130°F (54°C). Add warm milk mixture to flour mixture, and beat at medium speed until combined and cooled slightly, 2 minutes. Add 1 egg (50g), egg yolk, and orange zest, and beat at medium speed until combined. With mixer on low speed, gradually add 2 1/4 cups (281g) flour, beating just until combined and stopping to scrape sides of bowl.
Switch to the dough hook attachment. Beat at low speed until a soft, somewhat sticky dough forms, about 12 minutes, stopping to scrape dough hook and sides of bowl. Add up to remaining 1/4 cup (31g) flour, 1 tablespoon (8g) at a time, if dough is too sticky.
Lightly oil a large bowl. On a lightly floured surface, shape dough into a smooth round. Place dough in bowl, turning to grease top. Cover and let rise in a warm, draft-free place (75°F/24°C) until doubled in size, 40 minutes to 1 hour.
In a small bowl, whisk together remaining 1 egg (50g) and remaining 1 tablespoon (15g) water.
Lightly punch down dough. Cover and let stand for 5 minutes. Turn out dough onto a lightly floured surface, and roll into a 24x12-inch rectangle. Using a small offset spatula, spread Almond Cream (recipe below) onto dough, leaving a ½-inch border on one long side. Sprinkle with cranberries. Brush border with egg wash. Starting with opposite long side, roll up dough, jelly roll style; pinch seam to seal. Gently shape log to even thickness, if necessary. Trim edges flat. Place log on a sheet of parchment paper. Form dough into a circle. Brush trimmed ends with egg wash, and press together, pinching dough to seal.
Using a serrated knife or kitchen scissors, cut three-fourths of the way into dough, being careful not to cut all the way through dough. Make a second cut 1 inch from first cut. Repeat process around the circle until you reach first cut. Gently turn each slice onto its side, slightly overlapping with the previous piece. Slide parchment onto a baking sheet. Cover and let rise in a warm, draft-free place (75°F/24°C) until puffed, 20 to 30 minutes.
Preheat oven to 350°F (180°C). Brush egg wash onto dough.
Bake until lightly golden and an instant-read thermometer inserted in center registers 190°F (88°C), 30 to 45 minutes, loosely covering with foil to prevent excess browning, if necessary. Let cool on pan for 10 minutes. Remove from pan, and drizzle with Orange Glaze (recipe below). Serve warm or at room temperature.
