Although you took care to create a super-airy batter, Dutch babies by nature are supposed to collapse once they come out of the oven. This rise and fall in the cooking process gives the final product a satisfying, puffy texture. That said, it is still supposed to puff up in the oven!
DO NOT open your oven once your Dutch baby is inside!
If your Dutch baby did not rise enough (or at all), it could be a combination of different factors. It’s important to make sure that your oven is super hot at 425 degrees—and that your skillet is, too. One classic baking mistake that also applies to this recipe is opening the oven door during baking. I know it’s tempting. But don’t do it! It’s better to keep an eye on it through the glass and not open the door. All that heat needs to stay inside the oven to achieve the best results.
Dutch babies need the perfect batter consistency, so pay attention!
The batter is another factor. If you under mix the batter, you won’t get that airy texture. If you overmix the batter, it might start developing too much gluten structure, resulting in a dense pancake. Just follow the instructions carefully and you’ll have a perfect Dutch baby pancake in no time!
