Marbled Babka
Dough:
3.5 cups flour
1 tablespoon dry yeast
1/3 cup sugar
2 eggs
8 tablespoon (1 stick) butter
3/4 cup lukewarm milk
1/2 teaspoon salt
​
Filling:
12 tablespoons room temperature butter
150-gram light brown sugar
80-gram cocoa
generous amount of Nutella
​
Eggwash:
1 whole egg,
1 teaspoon milk
​
note: if you do not want to use Nutella, double the cocoa filling
​
Dough:
In a mixing bowl, combine flour, yeast, sugar, eggs, butter, salt and milk.
Knead about 7 minutes (speed #2 in KitchenAid).
Cover and place in the fridge overnight.
​
Filling:
In a food processor combine well all filling ingredients.
The filling can be made any time before you need it, but need to be soft enough for easy spreading.
​
Assemble the cake:
Remove the dough from the fridge.
Cut in half.
On a floured surface roll it out to a very thin 10"x14" rectangle.
Spread almost 1/2 of the filling leaving a narrow margin.
Fold into 2 and roll out again to a thin layer. Spread with the filling.
Roll into a tight roulade.
Repeat with the other half of the dough.
You may place the first roulade in the fridge while working with the second.
​
Cut the roulade in half, place so cut side is up and twist the 2 halves together, keeping the cut side up.
​
Repeat with the second roulade.
​
Place each roulade in a lined and oiled baking pan.
Let rest for at least 60 minutes.
The cake will not rise much.
​
You may bake in a regular baking pan or place in a loaf pan.
​
Brush with the egg wash.
​
Bake in 350f 30-35 minutes.
​
Cool completely before slicing.
