Preheat your oven to 350°F (175°C) and grease a baking sheet with butter or line it with parchment paper.

In a mixing bowl, combine the ricotta cheese, sugar, vanilla extract, almond extract, and egg. Mix until smooth.

In a separate bowl, sift together the flour, baking powder, and salt.

Gradually fold the dry ingredients into the ricotta mixture until combined, being careful not to overmix.

Fold in the slivered almonds evenly throughout the dough.

Shape the dough into pillow-like balls and place them on the prepared baking sheet.

Bake in the preheated oven for 15-18 minutes until lightly golden.

Remove from the oven and cool on a wire rack for about 10 minutes. Dust with powdered sugar before serving.
