Place a standard 12-muffin pan on a rack in the middle of the oven and heat the oven to 425°F.
Place pancake mix, water, eggs, sugar, and vanilla extract in a blender/food processor fitted with the blade attachment. Blend for 1 minute — batter will be very runny. Let batter rest for 10 minutes.
Carefully remove the preheated muffin pan from the oven. Add 1 piece of butter to each well. Pour the batter into the wells, about 3-4 tablespoons per well.
Bake until Dutch babies are puffed and lightly golden brown, about 15 minutes. Let cool for 1 minute before serving.
Spoon 1-2 tablespoons lemon curd into well of each Dutch baby; sprinkle with powdered sugar and garnish with cherry and mint leaf.
