01 -  Preheat oven to 400°F. Line a baking sheet with parchment paper. 
 02 -  In a large mixing bowl, combine the flour, granulated sugar, baking powder, and salt with a whisk. 
 03 -  Add cold, cubed butter to the bowl and cut it into the flour mixture with a pastry cutter or fingertips until the mixture resembles coarse crumbs. 
 04 -  Gently fold in the chopped dried cranberries, finely diced jalapeño, and chilled cream cheese cubes until distributed evenly. 
 05 -  In a small bowl, whisk together the heavy cream and egg. Pour over the dry mixture and stir just until the dough forms; avoid overmixing. 
 06 -  Transfer dough to a lightly floured surface. Pat into a 1-inch thick disc, then slice into 8 equal wedges and arrange them on the prepared baking sheet. 
 07 -  Brush the tops with heavy cream and sprinkle with coarse sugar if desired. Bake for 16 to 18 minutes or until golden brown. Allow to cool slightly before serving.
