01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, combine almond flour, sugar, egg white, softened butter, almond extract, and salt. Mix until a smooth paste forms.
03 - Roll out the thawed puff pastry on a lightly floured surface into a 12x12 inch square.
04 - Cut the pastry into 4 equal strips, then cut each strip in half to create 8 rectangles.
05 - Place about 1 tablespoon of almond filling down the center of each rectangle, leaving a border around the edges.
06 - Fold each rectangle in half lengthwise, covering the filling and sealing the edges by pressing gently.
07 - With a sharp knife, make 3–4 cuts along the sealed edge of each pastry to create the claw effect. Gently curve the pastries into a slight arc to fan out the toes.
08 - Transfer to the prepared baking sheet. Brush each bear claw with beaten egg, sprinkle with sliced almonds and coarse sugar if using.
09 - Bake for 18–22 minutes, or until puffed and golden brown.
10 - Allow to cool slightly before serving.
