Flaky bear claw pastries filled with sweet almond paste are a beloved American bakery classic. Their distinctive shape and rich filling make them a memorable breakfast indulgence.
Warm the milk gently to 110°F and dissolve the active dry yeast with a pinch of sugar; let it stand for 5 minutes until foamy.
In a mixing bowl, combine the all-purpose flour, salt, and sugar. Cut in chilled unsalted butter until the mixture resembles coarse crumbs.
Add the yeast mixture, one egg, and vanilla extract to the dry ingredients. Knead until a soft dough forms, then cover and let rise in a warm place for 1 hour.
For the filling: mix almond paste, slivered almonds, and remaining egg in a small bowl until smooth and spreadable.
Roll the dough out on a lightly floured surface to a 12x16 inch rectangle. Spread the almond filling over half, then fold dough over to cover. Cut into 8 sections, and make 3–4 slits on one side of each for the 'claws.'
Arrange pastries on a parchment-lined baking sheet, shape claws by gently separating slits, and let rise for 30 minutes.
Bake in a preheated 375°F oven for 18–22 minutes until golden brown; cool slightly before serving.
