Preheat a baking sheet in a 450 degrees F oven. Roll out 1 pound pizza dough into a 12-inch round. Brush with melted butter and sprinkle with sugar. Bake on the hot baking sheet until golden, about 8 minutes. Brush with 1/4 cup raspberry jam, then bake 2 more minutes. Cool slightly. Beat 1/3 cup mascarpone or cream cheese with 3 tablespoons confectioners' sugar and 1/2 teaspoon vanilla. Spread over the pizza and top with raspberries, toasted almonds and confectioners' sugar.
