I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Preheat the oven to 425°F and line a large baking sheet with parchment paper.
In a small bowl, mix together all of the almond flour, granulated sugar, salt, eggs, and almond extract until fully combined.
Lay the puff pastry on a lightly floured surface and cut it into 10 equally sized rectangles. Score each rectangle, leaving a half-inch border, and pierce the centers several times with a fork. Place them on the prepared baking sheet.
Divide the filling evenly between the rectangles, placing it in the centers of the rectangles. Mix the remaining egg with 1 tablespoon of water and brush the edges of the pastry. Bake for 15 minutes or until the pastry is golden and puffed. Cool completely before icing.
Simple Icing
Whisk together the powdered sugar, heavy cream, and vanilla extract, then drizzle over the cooled danishes and top with toasted almonds. Enjoy!
