Chocolate German pancakes

We've been making what we call "German Pancakes" in our family forever - and I just now found out they're also known as Dutch babies.

Here's our original recipe:

German Pancakes

1 cup milk
1 cup flour
6 eggs
1/4 tsp salt
2-3 Tbs butter.

Mix all ingredients except for butter in blender. Preheat oven to 450. Put butter in a glass pie pan or casserole dish and put in oven until butter melts. Then pour in batter and bake until it puffs up and is golden - 15-20 minutes. We like to drizzle it with fresh lemon juice and sprinkle with powdered sugar.

Now here's the chocolate version from marthastewart.com

Chocolate Dutch Baby

3/4 cup whole milk
3 large eggs
1/3 cup all-purpose flour (spooned and leveled)
1/4 cup unsweetened cocoa powder, sifted
1/4 teaspoon coarse salt
1/2 teaspoon pure vanilla extract
1/4 cup granulated sugar
2 tablespoons unsalted butter
3 tablespoons confectioners' sugar, for dusting

Preheat oven to 425 degrees. In a blender, combine milk, eggs, flour, cocoa powder, salt, vanilla, and granulated sugar. Blend until foamy, 1 minute. In a large cast-iron skillet (I think a glass dish would work), melt butter over medium. Pour batter into skillet and immediately transfer to oven. Bake until puffed and set, 20 minutes. Dust with confectioners' sugar and serve immediately.

Someone try this and let me know how it tastes!

Ok - I tried this recipe and it's delicious.
