125 g all-purpose flour
1.25 ml fine salt
1.25 ml pure vanilla extract
3 large eggs, at room temperature
160 ml milk, at room temperature
45 g clarified butter, melted
80 g fresh blueberries, or more to taste
15 g unsalted butter, melted
1/2 Meyer lemon, juiced
30 g powdered sugar, or to taste
30 ml maple syrup, or to taste
Step 1
Preheat the oven to 220°C (425°F).
Step 2
In a high-speed blender, combine flour, salt, vanilla extract, eggs, and milk. Blend on high speed until completely smooth and very thin, about 1 minute.
Step 3
Place a 23- or 25-cm cast iron skillet over high heat. Add clarified butter into the skillet and use a pastry brush to grease the sides. Heat butter until just starting to smoke.
Step 4
Quickly and carefully pour the batter into the center of the skillet, then sprinkle blueberries over top. Transfer skillet to the center of the preheated oven and bake until browned and nicely puffed, 20 to 25 minutes.
Step 5
Carefully remove from the oven and immediately brush the top with melted butter. Squeeze lemon juice over top as Dutch baby deflates. Dust with powdered sugar.
Step 6
Cut in wedges to serve and drizzle with maple syrup.
