Step 1

Preheat oven to 350 degrees and position baking rack in the middle of the oven. Use 1 tablespoon of butter to grease a 9-inch standard springform pan. Add in one tablespoon of powdered sugar and move around pound, shaking out excess when coated. Set aside.

Step 2

In a medium mixing bowl, whisk together the flour, baking powder, and salt. Set aside.

Step 3

In a large mixing bowl with handheld mixer or stand up mixer fitted with paddle attachment, cream together the stick of softened butter, sugar, and ricotta cheese until light and fluffy, about 5 minutes. Add in the eggs and almond extract and cream together for another minute. Pour in the flour mixture and mix until combined. Fold in the finely chopped almonds.

Step 4

Pour the batter into the prepared springform pan. Bake on center rack for 45-55 minutes, or until a toothpick inserted in cake comes out clean. Let cool in pan for at least 10 minutes before releasing springform and cooling on wire baking rack completely.

Step 5

For the topping, sprinkle sliced almonds on top of cooled cake. Place the powdered sugar in a fine mesh sieve to shake on top of cake just until cake is just covered.
