In a blender, combine all the batter ingredients in the order they’re listed. Blend until smooth.
Heat the air fryer to 400℉ and place the empty cake pan (see note 1) inside for 4 minutes to get it really hot. Generously grease the hot cake pan with cooking spray. Cut 2-1/2 tablespoons butter into 3 equal pieces and place in the bottom of the cake pan. Carefully use tongs to lower the cake pan into the air fryer basket. Cook for 1–2 minutes or just until butter is melted.
Remove and immediately pour 1 cup of the batter into the pan in a circular motion. Return pan to air fryer and cook at 400℉ for 7–10 minutes. It is perfect at 8 minutes in my air fryer.
Using tongs, remove the cake pan from the air fryer. Repeat with the remaining 2 cups of batter, making 2 more Dutch Babies.
Melt butter in a medium pot over medium heat. Once melted, add in both sugars. Stir until combined. Add in the heavy cream and reduce heat to low. Simmer, stirring occasionally, for 5 minutes. Remove from heat and stir in vanilla and salt.
Add fresh berries and vanilla syrup to your Dutch Babies and serve.
Notes
Note 1: You can create your own cake pan with 2 sheets of foil. Place two sheets of foil on top of each other, then fold into the shape of a 6-inch round cake pan, about 2-inches tall. If it’s not tall, the Dutch Baby may spill out as it rises. Generously grease with cooking spray and watch bake time closely. Dutch Babies in foil pans take about 1–3 minutes longer in my air fryer.Storage: Store batter in fridge overnight. Dutch babies are best eaten right after being made.Nutrition Note: Nutrition information will vary, depending on how much syrup you use.
