In the bowl of a stand mixer fitted with the dough hook, combine warm milk (100 Degrees F), a pinch of sugar, and the active dry yeast. Allow it to sit for about 5-10 minutes until frothy.
Into the bowl of the mixer add 4 cups of flour (reserve 1/2 cup), sugar, salt, and orange/lemon zest, softened butter, and eggs to the yeast mixture.
Knead the dough on medium-low speed until it becomes smooth and elastic about 5 minutes. Add in the remainder of the flour if needed.
Transfer the dough to a lightly floured surface and shape into a ball. Place in a greased bowl and cover with plastic wrap (I use a shower cap). Let it rise in a warm place for 1-2 hours or until it doubles in size.
Make the filling - In a separate bowl, mix chopped pecans, sugar, cinnamon, cardamom, and melted butter. Set aside.
Roll out the dough into a large rectangle on a floured surface. Sprinkle the filling evenly over the dough. Size doesn't matter.
Roll the risen dough tightly into a log and make a U-shape. Cut the log lengthwise about halfway down, exposing the layers of filling. Twist the two halves together, creating a braided appearance. It is a beautiful rustic bread.
Transfer the twisted dough into a well-greased Babka pan or a regular cake pan. Cover it and let the dough rest for an additional 30-60 minutes.
Preheat the oven to 350°F (180°C). Bake the Babka for 35-45 minutes or until golden brown. If the top is browning too quickly, cover it with foil.
While the Babka is still warm, brush the top with a simple sugar glaze made from powdered sugar and citrus juice. Room temperature or warm water can also be used.
Allow the Easter Babka to cool before slicing. Serve it with joy and celebrate the rich traditions of Easter with family and friends
