Preheat the oven to 400°F (200°C).

In a bowl, sift together the almond powder, powdered sugar, flour, baking powder, and salt. Set aside. In another bowl, using a whisk or handheld mixer, beat the whites until stiff peaks form. (Or, use a stand mixer fitted with the whip attachment.)

In a stand mixer fitted with the paddle attachment (or with a handheld mixer or a wooden spoon and some stamina), beat the butter until creamy and soft. Add the egg yolks, ne at a time, beating after each addition. Beat in the almond extract. Then add the dry ingredients, beating just until thoroughly combined. The mixture will be a bit stiff. On low speed, slowly add half of the whipped whites, mixing just until combined. Using a rubber spatula, gently fold in the remaining whites.
