According to Sunset magazine, Dutch babies were introduced in the first half of the 1900s at Manca's Cafe, a family-run restaurant in Seattle owned by Victor Manca. While these pancakes are derived from the German pancake dish, it is said that the name Dutch baby was coined by one of Victor Manca's daughters. In 1942, Manca's Cafe owned the trademark for Dutch babies, although the cafe later closed in the 1950s.
This pumpkin Dutch baby recipe comes from the website Baking Bites. I've been making traditional Dutch babies for weekend breakfasts for years and always put the ingredients in the blender and did for the recipe too. The eggs need to be whipped until frothy and then add the rest of the ingredients. This one did not puff up as much as traditional ones do, probably because of the weight of the pumpkin puree. Andrew, Karen, the Hub and I acted as taste testers, and everyone like the recipe.
