Heat oven to 325°F. Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, sugar, baking powder, and salt. Using a pastry blender, cut butter into flour mixture to form crumbs; mix in fruit and almonds; set aside.
In a separate bowl, mix together cheese, egg, vanilla, and lemon zest. Combine wet with dry ingredients, mixing until most of the flour is moistened.
Turn dough out onto a floured surface; knead two or three times, until it holds together. Divide in half. Roll each piece into an 8-by-7-inch oval about 1/2 inch thick. Fold each piece in half, leaving the edge of the top half about 1/2 inch short of the edge of the bottom half. Press the top edge of the dough into the bottom edge to form a traditional stollen shape. Place on baking sheet. Bake until lightly browned around edges, about 40 minutes. A toothpick inserted in center should come out clean.
Remove from oven; transfer to a rack. Brush each with 2 tablespoons butter. Sprinkle heavily with powdered sugar. Cool. Repeat with remaining butter and sugar. Wrap in plastic wrap until ready to serve. Makes 2 loaves.
