German Apple Pancake Recipe

Adjust rack to upper middle position and preheat oven to 500°F. Whisk flour, 1 tablespoon sugar, and salt in medium bowl to combine. Whisk in milk, yogurt, eggs, and vanilla until just combined; set batter aside. Stir remaining 4 tablespoons sugar with cinnamon in a small bowl. Heat butter in 10-inch non-stick oven-safe skillet over medium heat until melted. Increase heat to medium high and add apples and cinnamon-sugar to pan. Cook, stirring frequently, until apples have softened and are beginning to caramelize, 6 to 8 minutes. Remove from heat, pour batter over apples and immediately place pan in oven. Reduce heat to 425°F and bake until pancake is puffed, just set in center, and golden around the edges, about 15 minutes. Cool pan on wire rack for 5 minutes, then carefully invert pancake onto serving plate. Dust with powdered sugar and serve.
