A Blueberry Dutch Baby is a quick and easy baked oven pancake often called a German Pancake. Its high puffs, crisp edges, and tender delicious center is such a treat that it just might become a weekend tradition!
Preheat the oven to 425 degrees F. Add 2 tablespoons butter and the blueberries in a 10-inch cast-iron skillet and place in the oven as it heats. Remove once the butter melts; 3 to 5 minutes.
As the butter is melting, whisk the milk, eggs, maple syrup, and vanilla in a bowl. Add the flour, cinnamon, and salt; whisk until very smooth with no dry flour remaining. You can also blitz the batter in a blender.
Remove the skillet from the oven and brush the melted butter to grease the sides of the skillet.
Quickly but carefully pour the batter into the center of the hot skillet. If necessary, give it a quick stir to distribute the blueberries.
Return the skillet to the oven and bake until browned and nicely puffed, 15 to 20 minutes. Don't open the oven door for the first 15 minutes!
Remove from the oven, top with pats of remaining butter, and dust with confectioners’ sugar.
Notes
Make ahead: Make the batter the night before and refrigerate until ready to bake. Let the batter come to room temperature before pouring into the hot skillet.
