One of the things my wife, Deborah, loves to make is a Dutch baby. If pancakes and popovers had a baby, it would be a Dutch baby! Hers is savory with lots of cheese. I decided to switch it around and make her a dessert, taking out the cheese and replacing it with vanilla and lemon. I think the best part is when you take it out of the oven... it's like a mutant soufflé!
Preheat oven to 425F.
Add eggs, milk, flour, sugar, salt, lemon zest, and vanilla paste to blender. Blend to combine all ingredients.
Heat a cast iron skillet on the stove top until hot. Add butter and melt completely. Pour batter into the hot pan, and place in oven. Cook for 15-20 minutes until it is golden brown and puffed up. Remove from oven and top with blueberry sauce and powdered sugar.
