Instructions

1
Preheat your oven to 180°C (350°F). Grease and flour an 8-inch (20 cm) round cake pan.
2
In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy.
3
Beat in the eggs one at a time, ensuring each egg is fully incorporated into the batter before adding the next. Stir in the vanilla extract.
4
In a separate bowl, whisk together the all-purpose flour, finely ground walnuts, baking powder, and a pinch of salt.
5
Gradually add the dry ingredients to the wet ingredients, mixing gently until just combined. Be careful not to overmix the batter.
6
Pour the cake batter evenly into the prepared cake pan and smooth the top with a spatula.
7
Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean.
8
Let the cake cool in the pan for 10-15 minutes before carefully inverting it onto a wire rack to cool completely.
9
Optionally, once cooled, dust the cake generously with confectioners' sugar and garnish with a few walnut halves before slicing and serving.
