In a large mixing bowl, mix together all of the ingredients (except the sliced almonds and powdered sugar) until combined.
Line a baking sheet with parchment paper and preheat the oven to 350F.
Taking the dough 2 tablespoons at a time, roll it into a cylinder shape, then shape the ends into points to create a crescent. Press some sliced almonds on top and arrange the cookies (at least 1 inch apart) onto the baking sheet.
Bake for 15-17 minutes, until golden.
Let the cookies cool, then dust them with powdered sugar and enjoy!
