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

In a mixing bowl, whisk together the ricotta cheese, granulated sugar, vanilla extract, almond extract, and egg until smooth and creamy (about 2–3 minutes).

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

Fold the dry ingredients into the wet mixture using a spatula until just combined, being careful not to overmix.

Gently fold in the slivered almonds until they are evenly distributed.

Shape the dough into golf ball-sized pillows and place them on the prepared baking sheet, spaced about 2 inches apart.

Bake for 15–18 minutes, or until lightly golden on top.

Allow to cool on a wire rack for about 10 minutes and dust with powdered sugar before serving.
