Grease two 8x4 loaf pans and line with parchment paper.
Divide the dough into two equal parts and roll each part into a 12x18 rectangle. (refrigerate the second piece while you shape the first one) Lightly flour your work surface and rolling pin, and rotate the dough as you roll to ensure it does not stick. Spread 1/2 of the remaining almond paste over the top of the rectangle dough.
Roll the dough into a spiral log, starting with the long side.
Move the two ends towards each other, so that the log will be shaped like a U.
Gently twist the two sides around each other.
Place the twisted dough in the prepared pan. Repeat with the second piece.
Brush the shaped babkas with the egg wash.
Top with the almond topping and set aside to rest for 90-120 minutes.
Bake for 35 minutes at 350F (180C) in a preheated oven until the inner temperature reads 90-210F (88-98C).
Remove from the oven and allow the bread to cool in the pan before inverting and serving.
